• Project
Enter the details of your project. Note that when exporting the results as a Project Report, the following characters are
automatically replaced with “_” (underscore) in order to prevent false representation in HTML format.
Characters: < > & “
• Calculation
Atmospheric Condition
Enter “Humidity” and “Temperature”. These parameters affect the speed of sound and the air absorption coefficient. The default
settings are 50% for humidity and 20°C for temperature. Check the “Air Absorption” checkbox to take attenuation of high
frequency components due air absorption into account in calculations.

Precision
Select the degree of precision used in the SPL calculation and contour calculation respectively. When a lower precision is
selected, Y-S3 uses an interpolation for faster processing. You may use a lower precision in the design stage for faster processing
and the highest precision in the final stage for checking the detailed results.
Phase Consideration
Check the “Interference Sum” checkbox to take phase interference into account when calculating the frequency characteristics
and sound pressure distribution. Energy summing calculations are performed if you do NOT check this box.
Sound Source for Calculation
Select “Swept Band Noise” or “Full Band Noise” for use as the sound source in the calculation. When “Swept Band Noise” is
selected, band pass noise assumed to be used. The bandwidth corresponds to the frequency selected in Aspect View. In this mode,
the overall level in Graph is the average energy of each band response. When “Full Band Noise” is selected, full band noise is
assumed to be used. The overall level in Graph is the summation of each band response. The “Swept Band Noise” mode is
convenient when you want to see the frequency characteristic while referring to the required SPL. You may easily deduce the
overall SPL by averaging the SPL results at several frequencies in this “Swept Band Noise” mode. The “Full Band Noise” mode
is more reasonable for a comparison of the calculated SPL with the value measured by using full band pink noise and real time
spectrum analysis.
Fig: Level difference between “Sound Source for Calculation” settings
Swept Band Noise Full Band Noise
Graph Overall
Select the frequency range of overall level displayed in Graph. The default range is 20 Hz to 20 kHz. For “Swept Band Nose” (cf.
previous section), the overall level denotes the average level of the response in the selected range. For “Full Band Noise”, the
overall level equals the summation of the response in the selected range. Check “A Weighted” checkbox to process the sound in a
similar manner to that of the human ear, using “A” characteristics. The Overall figures in Graph are displayed in dBA units.
Peak Factor of Source Signal
Select the source type from “Sine (Peak-to-RMS 3dB)”, “Pink (Peak-to-RMS 6dB)”, or “Music (Peak-to-RMS 10dB)”. “Sine”
has a 3 dB difference between the peak signal and RMS, “Pink” has 6 dB and “Music” has 10 dB. In this list, you select a
peak-to-RMS level in a practical sense. These levels are used by the clip level indicator and for auto tuning. “Output

Symmetry
Check this checkbox to place a mirror image of the speaker array with respect to the y-z plane. For a stereo system, when the left
side speaker is entered, the right side “mirrored” speaker will appear automatically. Speakers will overlap if Position x in “Array
Geometry” is set to the default (0.00). Please enter an appropriate figure. Note that since speaker figures are also mirrored, the
mirrored figure is different from the actual picture in some cases for some asymmetric models like IS2112AS or IF2115AS. This
will not affect calculation results. An asterisk (*) appears beside the array names of mirrored speakers, to help distinguish them
from the original speakers.
Array Geometry
Enter positional data for the speakers such as the splay, angle and coordinates of the speaker array. The contour diagram does not
display if the target point is not located on the receiving surface in Aspect View after you have positioned the speaker. Further,
the contour figure will not display if the target point is in an area obstructed by walls (first floor only) or floors. In both cases, the
sound pressure distribution that is displayed is based on calculations made for those areas that sound can travel to unobstructed.
Placing a speaker array outside the receiving surface or stage excludes it from calculations, and its output does not appear on
contour figure and sound pressure distribution.
Position
Enter the position coordinates of the speaker array. Defaults (x, y, z) = (0.00, 0.00, 8.00), with height set to 8 meters. The
coordinates are at the center rear point of the array. Click to place a speaker on the floor automatically. Enter the angle
you want. Floor-mounted speakers not facing the receiving surface and speakers with the same z-coordinates as the height of the
receiving surface will not have target points displayed on the receiving surface, and are thus not displayed in the contour figure.
Each coordinate can be set in the range of -99.99 m to 99.99 m (-328.0 ft to 328.0 ft).
Angle
Enter the angle of the speaker. Enter the Pan (default: 00.0), Tilt (default: 30.0), Rot (default: 00.0) angles. The angle can be set
in the range of -180.0 to 180.0.

Coverage (Distributed Speaker Layout Pattern)
Speakers are placed automatically based on the coverage area of the receiving surface. This function is useful when evaluating
the speaker placement necessary to obtain direct distribution of sound.
Layout Judgment
Set the defining parameters for “Pattern”, “Bandwidth” and “Center Frequency” from the list boxes and choose a density.
Pattern:
Select either “Rectangular” or “Hexagonal” as a layout pattern for speakers on a flat surface.
Band Width, Center Frequency:
Set the bandwidth and frequency used to calculate the coverage area. Although the narrower bandwidths allow closer
distributions to the desired frequencies, they are also subject to more extreme distribution changes caused by interference and
other factors. The default setting is 2 Oct. Band, 1 kHz, which should cope with most vocal bandwidths
Density:
Set the density of the coverage area on the receiving surface. Take the distance between the receiving surface and the plane
where the speakers are located (the height, for speakers installed in the ceiling) when setting this parameter. Generally, higher
ceilings mean increased distances between speakers, so you should select high density to achieve sound pressure above a
constant level.

6. Displaying Calculation Results
• Overview
Y-S
3
calculates responses on the audience area considering the arrangement of each speaker array, EQ, delay, system attenuation
and other related parameters. The results are displayed in Aspect View or Graph.
Aspect View
Aspect View displays the layout of the speakers, along with sound pressure distributions and contour figures based on calculation
results. To update calculation results, select the center frequency and bandwidth (1/1, 1/3, 1/6, FFT) from the list box in the upper
section of Aspect View, then select the calculation mode icon. If you set bandwidth to “FFT”, you can enter the bandwidth you
want in the text box between 44 – 22000Hz. Clicking after changing calculation conditions applies the new
conditions to the calculation results and updates Aspect View, Balloon view and Graph.
• Contour figure
Y-S3 displays the contour figure for -3 dB, -6 dB and -9 dB for the target point of the speaker arrays or each speaker array
selected in Aspect View. The contour figure is depicted using three lines, indicating -3 dB (red), -6 dB (orange) and -9 dB (green)
drops in sound pressure from the target point that is closest to the speaker arrays or speaker. You can show or hide these lines by
selecting [Contour (-3dB) (3)], [Contour (-6dB) (6)], or [Contour (-9dB) (9)] from the [View (V)] menu. These figures are the
bandwidth and center frequency figures selected in the list boxes in the upper area of Aspect View. When speakers are mounted
on the floor, the contour figure is not available when the target point is not located on the receiving surface or is in an area
obstructed by walls (first floor only) or floors. Additionally, Y-S
3
does not display target points or contours of speaker arrays
placed using the “Symmetry” function in “Enclosure type - Auto layout” and “Enclosure type - Manual layout”. To display
contour figures for walls, open the Project Properties window from the [File (F)] menu, and place a check in the “Contour
Display” checkbox in Others. Y-S
3
does not display a sound pressure distribution for walls. This wall is used for display the
contour figure only, and is treated as being acoustically transparent. Thus calculations do not take reflections from this wall into
account.
Array Mode
Displays a contour figure for speakers displaying target points. A speaker array made up of a single speaker will have the same
display as “Single Mode”. Speakers distributed on a plane are treated as individual speakers, and thus have the same display as
“Single Mode”.
Single Mode
Displays a contour figure for each speaker displaying target points. When you have placed multiple speakers, you can use the
checkboxes in Speaker List to turn each speaker on/off. Since the contour figures for each speaker are calculated relative to the
respective target points, the SPL for each speaker will be different even for contour lines of the same color.

10. General Theory
General calculation methods
• Y-S
3
computes the speaker array response at the receiving point or audience area.
• The responses are computed by combining the responses from each speaker based on a geometrical simulation.
• Each speaker response is computed using measured directional impulse responses. First by selecting the impulse response
for the corresponding direction based on the relationship between the receiver point and the speaker position, and then
considering the effects of attenuation by distance, air absorption, amplifier type, system attenuation, and processor settings
(EQ, delay).
• There are two methods of combining responses: a method that considers the interference and a method that is based on the
summing of energy and not taking the interference into account.
• The response is limited to direct sound. Calculations are performed as for a free sound field without any reflections.
• The sound pressure level is calculated assuming sine wave or pink noise input to the system.
• There are two types of pink noise: band-pass filtered noise for the “Swept Band Noise” option or overall noise for the “Full
Band Noise” option.
• The response for the two channels used in auralization is computed by first convolving the head-related transfer function
(HRTF) of the directions corresponding to each speaker’s response, and then combining these responses.
Auto setting methods
• There are two auto setting functions. “Auto layout” selects the appropriate speakers for the current room configuration, and
“Auto tuning” determines the parameters (Angle, EQ, Amp type, Input Level and Attenuation) for each speaker.
• The results for each function are only rough estimates, and adjustments or modifications will be necessary for either method.
Calculations are made based on the following theory.
1. Auto layout
• Y-S
3
selects the speaker type that is appropriate for the configuration of the room, its area, and the dimensions of the floor.
• Speaker positioning is conducted in accordance with the speaker arrangement methods (Center, Center + Side, Side) while
considering the ceiling height of the room.
• Angles are set to default: Pan and Rot = 0 degrees, Tilt = 30 degrees and Splay Angle = minimum.
2. Auto tuning
• Y-S
3
sets speaker parameters for each speaker array.
• Y-S
3
decides the speaker angles (Pan, Tilt and Splay Angle) to minimize the standard deviation of the sound pressure level
within the area that is selected by the user as the coverage of the speaker array.
• When computing angles, the proper setting is selected from among the conditions in which all of the target points of the
speaker composing the speaker array are within the selected cover area.
• Y-S
3
decides the EQ and gain for each speaker so that the frequency responses are flat and their levels match the required
SPL set by the user at the target points of each speaker that composes the speaker array. (Note 1: In auto tuning, since sound
pressure level calculations at axis points are computed based on the summing of energy, peaks/dips from interference are not
corrected. Note 2: Delay is not tuned automatically. All the delays are set to 0 ms after auto tuning.)
• In the level adjusting, Y-S
3
first decides the necessary output power for each speaker referring to the required SPL. Then,
Y-S
3
decides the attenuation level to adjust the necessary power difference between the speakers in one speaker array. Finally,
Y-S
3
decides the input signal level from the necessary output power and amplifier gain.

Editing Project Properties • Overview You can edit parameters such as the environment and processor selection, amplifier voltage, and text in the Project Properties window. Click in the tool bar or select [Project Properties (P)] from the [File (F)] menu, open the Project Properties window, and edit the contents of the Project, Calculation, System, and Others views. These parameters may be saved as a user default setting by clicking the button. When you click the button, all parameters in every tab sheet within the Project Properties window are saved as the default setting. In order to apply the saved setting, click icon. When you create a new project, the software default setting is applied. • Project Enter the details of your project. Note that when exporting the results as a Project Report, the following characters are automatically replaced with “_” (underscore) in order to prevent false representation in HTML format. Characters: < > & “ • Calculation Atmospheric Condition Enter “Humidity” and “Temperature”. These parameters affect the speed of sound and the air absorption coefficient. The default settings are 50% for humidity and 20°C for temperature. Check the “Air Absorption” checkbox to take attenuation of high frequency components due air absorption into account in calculations. 16 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 Precision Select the degree of precision used in the SPL calculation and contour calculation respectively. When a lower precision is selected, Y-S3 uses an interpolation for faster processing. You may use a lower precision in the design stage for faster processing and the highest precision in the final stage for checking the detailed results. Phase Consideration Check the “Interference Sum” checkbox to take phase interference into account when calculating the frequency characteristics and sound pressure distribution. Energy summing calculations are performed if you do NOT check this box. Sound Source for Calculation Select “Swept Band Noise” or “Full Band Noise” for use as the sound source in the calculation. When “Swept Band Noise” is selected, band pass noise assumed to be used. The bandwidth corresponds to the frequency selected in Aspect View. In this mode, the overall level in Graph is the average energy of each band response. When “Full Band Noise” is selected, full band noise is assumed to be used. The overall level in Graph is the summation of each band response. The “Swept Band Noise” mode is convenient when you want to see the frequency characteristic while referring to the required SPL. You may easily deduce the overall SPL by averaging the SPL results at several frequencies in this “Swept Band Noise” mode. The “Full Band Noise” mode is more reasonable for a comparison of the calculated SPL with the value measured by using full band pink noise and real time spectrum analysis. Fig: Level difference between “Sound Source for Calculation” settings Swept Band Noise Full Band Noise Average SPL SPL Summation Frequency Frequency Graph Overall Select the frequency range of overall level displayed in Graph. The default range is 20 Hz to 20 kHz. For “Swept Band Nose” (cf. previous section), the overall level denotes the average level of the response in the selected range. For “Full Band Noise”, the overall level equals the summation of the response in the selected range. Check “A Weighted” checkbox to process the sound in a similar manner to that of the human ear, using “A” characteristics. The Overall figures in Graph are displayed in dBA units. Peak Factor of Source Signal Select the source type from “Sine (Peak-to-RMS 3dB)”, “Pink (Peak-to-RMS 6dB)”, or “Music (Peak-to-RMS 10dB)”. “Sine” has a 3 dB difference between the peak signal and RMS, “Pink” has 6 dB and “Music” has 10 dB. In this list, you select a peak-to-RMS level in a practical sense. These levels are used by the clip level indicator and for auto tuning. “Output configuration settings (Speaker Property - Config)” and “Auto tuning” in chapter 5. 17 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 • System Signal Processor Select the output processor type. The selected processor is used in [Export DME Configuration] (selected from the [File (F)] menu) and [Product List] (selected from the [Option (O)] menu). Each processor has different processing powers and number of outputs. The specifications are available in http://www.yamahaproaudio.com/. If you select “SP2060”, you can then select a processor that sets EQ and Delay values for all outputs, or one which sets values for each amplifier. The configuration used in “SP2060” is shown in the following table. Table: Configurations applied to each speaker type in SP2060 Speaker Type Configuration Tri-amp (IF3115t) 2 x 3-way Bi-amp (IF2112b, IF2115b, …) 3 x 2-way Passive (IF2112p, IF2115p, …) Multi Zone Combination (IH2115 + IL1115) 2 x 2-way + 2 x Aux AC for Amplifier Select the amplifier voltage. This figure is used to determine how clipping is displayed. You can check on the specifications of each amplifier at http://www.yamahaproaudio.com/. The default setting is “120 V”. 18 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 • Others Unit Select “Imperial” (feet and Fahrenheit) or “Metric” (meter and Celsius) for units of length and temperature. Listen Enter the coordinates of the principal performer or person speaking. These figures should be absolute coordinates. You should take height into account if you are using the equipment on a stage. For example, using a sound source 1.5 m for the stage floor, when the height of the stage floor is 0.8 m from the ground gives a total height of 2.3 m. Y-S3 refers to the origin point when creating auralization data. The auralization data is calculated using head-related transfer functions (HRTF) by assuming that the listener is facing the Origin Point. See chapter 6 for how to create auralization data. Contour Display Check the “Wall” checkbox to show the walls in Aspect View. The height of the wall is fixed at 5 m. You may check any unnecessary radiation onto the walls by checking the contour shown on the walls. Note that Y-S3 does not calculate the reflections from the walls even if this option is selected. Report Page Size Set the size of the page to print. You can select letter size or A4 paper. 19 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 4. Placing Speakers • Overview Place the speakers in the room. You can add positions for each speaker array on a conventional proscenium or stage, and place speakers on flat surfaces within the room such as ceilings and walls. • Installing Speakers By installing the speaker data that you’ve downloaded from the Yamaha Pro Audio website, you will be able to add the speakers you want to use to Y-S3. For the installation procedure, see “Installing Speaker Data” on page 4. • Adding a new speaker (Add Speakers) Click in Speaker List or select [Add New Array (N)] from the [Array (A)] menu to open the Add Speakers window. You can select the installation method (Enclosure type - Manual layout, Enclosure type - Auto layout, Distributed) from the list box. Place each speaker array for which you have entered details. Installed speakers will be appear in Aspect View, and are available for selection in Speaker List. See chapter 6 for details on calculation results. Speaker Arrays This is a very flexible installation method compatible with all Installation Series speakers. You can save installation data for each speaker array. (See chapter 5) Enclosure type - Manual layout: The method allows a great deal of freedom in speaker layout, allowing the “Array Type” selection, mirroring, and direct entry of coordinates. Enclosure type - Auto layout: Y-S3 will select an appropriate speaker array for your room and arrange them automatically, based on your “System Type” selection. Distributed Speakers You can arrange speakers with a fixed spacing on a level surface (e.g. wall or ceiling). For the compatible speakers, please check the website at http://www.yamahaproaudio.com. Since the speakers will be treated as part of the flat surface, you cannot save this arrangement. (See chapter 5) Distributed: Sets the parameters for the level surface in which speakers are placed, depending on your speaker and the “Plane Type” selections. Coverage: Y-S3 automatically places speakers in the coverage area on the receiving surface, depending on your selections for placement pattern and degree of consolidation of the receiving surface. Grid: You can place speakers at any intervals on a grid, based on your selections for placement pattern and the distance between speakers. 20 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 • Placing the speakers manually (Enclosure type - Manual layout) Click in Speaker List or select [Add New Array] from the [Array] menu to open the Add Speakers window. Select “Enclosure type - Manual layout” from the list box. Select a speaker array type and enter the coordinates and conditions for the area to calculate the results. Name Input a name for the new array (e.g. Center, Left, Right, Delays, etc). Y-S3 automatically assigns names for single speakers that compose the array like ***sp1, ***sp2 (*** is the array name). You can change these names also in Speaker List after placing the speaker array. To change them, select the speaker array or single speaker in Speaker List, right-click and select [Rename], then enter the new name. Array Type Select the speaker array type from the list box. When you would like to use an array type which is not shown in the list box, you need to import a speaker array template (“.ysd” file) from “ARRAY_LIBRARY” folder to the “Array Type” list. Select “Import Array Type” from the list box and Y-S3 imports the data to the “Array Type” list so that you may select the array type in the list box. The imported array type will remain on the list until you delete it, even after you restart the program. To delete the imported data from the list, delete the “.ysd” file from the “data_foldertemplate_folderSPA_DATA” folder in the program folder. Y-S3 requires at least one template to be present in the “Array Type” list. Placing an imported array template (.ysd) in the room will convert it to array data (.spa) containing the conditions for the speaker array, which you can save and load. (See chapter 5) The suffixes in the speaker array template have the following meanings. p: Passive, b: Bi-amp, t: Tri-amp, r: rotate (horn-rotated), floor: +3dB (adding reverberations from the floor) You can check the specifications for each speaker on the website at http://www.yamahaproaudio.com/.

For a stereo system, when the left side speaker is entered, the right side “mirrored” speaker will appear automatically. Speakers will overlap if Position x in “Array Geometry” is set to the default (0.00). Please enter an appropriate figure. Note that since speaker figures are also mirrored, the mirrored figure is different from the actual picture in some cases for some asymmetric models like IS2112AS or IF2115AS. This will not affect calculation results. An asterisk (*) appears beside the array names of mirrored speakers, to help distinguish them from the original speakers. Array Geometry Enter positional data for the speakers such as the splay, angle and coordinates of the speaker array. The contour diagram does not display if the target point is not located on the receiving surface in Aspect View after you have positioned the speaker. Further, the contour figure will not display if the target point is in an area obstructed by walls (first floor only) or floors. In both cases, the sound pressure distribution that is displayed is based on calculations made for those areas that sound can travel to unobstructed. Placing a speaker array outside the receiving surface or stage excludes it from calculations, and its output does not appear on contour figure and sound pressure distribution. Position Enter the position coordinates of the speaker array. Defaults (x, y, z) = (0.00, 0.00, 8.00), with height set to 8 meters. The coordinates are at the center rear point of the array. Click to place a speaker on the floor automatically. Enter the angle you want. Floor-mounted speakers not facing the receiving surface and speakers with the same z-coordinates as the height of the receiving surface will not have target points displayed on the receiving surface, and are thus not displayed in the contour figure. Each coordinate can be set in the range of -99.99 m to 99.99 m (-328.0 ft to 328.0 ft). Angle Enter the angle of the speaker. Enter the Pan (default: 00.0), Tilt (default: 30.0), Rot (default: 00.0) angles. The angle can be set in the range of -180.0 to 180.0. Splay Angle Select the splay angle of the speaker array from the list box. 23 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 24 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 • Placing the speakers automatically (Enclosure type - Auto layout) Y-S3 can automatically place speakers in the room. The appropriate speaker types for the configuration of the room, such as the surface area of the audience area, and the ratio of its width and length, can be selected automatically. Click in Speaker List or select [Add New Array (N)] from the [Array (A)] menu to open the Add Speakers window. Select “Enclosure type - Auto layout” from the list box. Select “System Type” and ceiling height and click to begin calculations and configure the system composition. Note that auto layout only takes the 1st floor into consideration; 2nd and higher floors are not taken into consideration. When calculations are complete, Y-S3 displays a message prompting you to carry out auto tuning. Click to begin auto tuning. Click to finish without auto tuning. See chapter 5 for details about auto tuning. You cannot use “Auto layout” in “SPL Mode” when Y-S3 displaying a sound pressure distribution. Always switch to “Array Mode” or “Single Mode” before using this function. Additionally, “Auto layout” deletes any existing speaker arrays that have already been placed and places new speaker arrays. Speakers placed suing the “Distributed” function are not deleted. This is useful in instances such as when you want to replace speakers on a stage or proscenium but retain speakers installed in the ceiling.

The following diagrams depict the differences before and after auto-tuning speaker arrays (included mirrored speaker arrays) in area setting above. Before Auto Tuning After Auto Tuning 39 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 Setting methods • • • • • Y-S3 sets speaker parameters for each speaker array. Y-S3 decides the speaker angles (Pan, Tilt and Splay Angle) to minimize the standard deviation of the sound pressure level within the area that is selected by the user as the coverage of the speaker array. When computing angles, the proper setting is selected from among the conditions in which all of the target points of the speaker composing the speaker array are within the selected cover area. Y-S3 decides the EQ and gain for each speaker so that the frequency responses are flat and their levels match the required SPL set by the user at the target points of each speaker that composes the speaker array. (Note 1: In auto tuning, since sound pressure level calculations at axis points are computed based on the summing of energy, peaks/dips from interference are not corrected. Note 2: Delay is not tuned automatically. All the delays are set to 0 ms after auto tuning.) In the level adjusting, Y-S3 first decides the necessary output power for each speaker referring to the required SPL. Then, Y-S3 decides the attenuation level to adjust the necessary power difference between the speakers in one speaker array. Finally, Y-S3 decides the input signal level from the necessary output power and amplifier gain. 40 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 5-2.

Displaying Calculation Results • Overview Y-S3 calculates responses on the audience area considering the arrangement of each speaker array, EQ, delay, system attenuation and other related parameters. The results are displayed in Aspect View or Graph. Aspect View Aspect View displays the layout of the speakers, along with sound pressure distributions and contour figures based on calculation results. To update calculation results, select the center frequency and bandwidth (1/1, 1/3, 1/6, FFT) from the list box in the upper section of Aspect View, then select the calculation mode icon. If you set bandwidth to “FFT”, you can enter the bandwidth you want in the text box between 44 – 22000Hz. Clicking after changing calculation conditions applies the new conditions to the calculation results and updates Aspect View, Balloon view and Graph. • Contour figure Y-S3 displays the contour figure for -3 dB, -6 dB and -9 dB for the target point of the speaker arrays or each speaker array selected in Aspect View. The contour figure is depicted using three lines, indicating -3 dB (red), -6 dB (orange) and -9 dB (green) drops in sound pressure from the target point that is closest to the speaker arrays or speaker. You can show or hide these lines by selecting [Contour (-3dB) (3)], [Contour (-6dB) (6)], or [Contour (-9dB) (9)] from the [View (V)] menu. These figures are the bandwidth and center frequency figures selected in the list boxes in the upper area of Aspect View. When speakers are mounted on the floor, the contour figure is not available when the target point is not located on the receiving surface or is in an area obstructed by walls (first floor only) or floors. Additionally, Y-S3 does not display target points or contours of speaker arrays placed using the “Symmetry” function in “Enclosure type - Auto layout” and “Enclosure type - Manual layout”. To display contour figures for walls, open the Project Properties window from the [File (F)] menu, and place a check in the “Contour Display” checkbox in Others. Y-S3 does not display a sound pressure distribution for walls. This wall is used for display the contour figure only, and is treated as being acoustically transparent. Thus calculations do not take reflections from this wall into account. Array Mode Displays a contour figure for speakers displaying target points. A speaker array made up of a single speaker will have the same display as “Single Mode”. Speakers distributed on a plane are treated as individual speakers, and thus have the same display as “Single Mode”. Single Mode Displays a contour figure for each speaker displaying target points. When you have placed multiple speakers, you can use the checkboxes in Speaker List to turn each speaker on/off. Since the contour figures for each speaker are calculated relative to the respective target points, the SPL for each speaker will be different even for contour lines of the same color.

Exporting Configurations in DME Designer Format Y-S3 can automatically generate an output system configuration for all placed speaker arrays and save them in DME Designer Project format. Saving a Configuration in DME Designer Project File (.daf) Format To save the current configuration in DME Designer Project File (.daf) format, click on the tool bar, or select [DME Configuration (D)… (*.daf)] from [Export (E)] in the [File (F)] menu and enter a file name. You may open a saved .daf file in DME Designer. The .daf file includes the necessary number of processors and configurations for the placed speaker arrays. Saving a Configuration in DME Designer Device Configuration (.ddf) Format You can also export the DME's internal configuration as Device Configuration file. To save the configuration in Device Configuration (.ddf) format, select [DME Configuration(M)… (*.ddf)] from [Export (E)] in the [File (F)] menu, and enter a file name. To load a file into DME Designer, start DME Designer, and select [Create New Group] from [Import Device Configuration] in the [File] menu on the main screen. You may also import the configuration to the DME already in the project file that has been made with DME Designer. Select the processor from [Import Device Configuration] in the [File] menu of DME Designer, and load the saved file. Saving a Configuration in DME Designer Library File (.cel) Format You may save the configuration of the output component of each placed speaker array in Library File (.cel) format. Select [DME Configuration(E)… (*.cel)] from [Export (E)] in the [File (F)] menu, and specify the destination folder. In the specified folder, a folder is created for each speaker array, and the library file is saved in each array folder. The file name is (the name of the speaker array)_(the component name).cel or (the name of the speaker array)_(the name of the speaker)_(the component name).cel. If a file with the same name already exists, the file will be overwritten. If necessary, create a new folder. The component name corresponds to the DME Designer configuration, which is delay (Delay-Short 1 Output), peq (PEQ-Mono 8 Band), or SPProc (Speaker Processor). The saved library file can be opened in DME Designer and Amp Editor. For details on how to open library files, see the respective software owner's manual. To use a Speaker Processor library file that has been saved using Y-S3 in Amp Editor, first convert the file to a TXn library file (*.ce2) using the Speaker Processor Library Converter. When the library file is recalled in Amp Editor, the data in the file will be changed to limiter values that match the TXn gain structure. A 1-way library file can be loaded without having to first convert it into a TXn library file (*.ce2). For details about Speaker Processor Library Converter, see the Amp Editor owner's manual. Amp Editor does not support the loading of delay library files.

Other Functions • Input Level Negotiation Adjust input levels (Speaker Property - Config - Input Level) from all installed speaker arrays to a fixed level. Select [Input Level Negotiation (I)] from the [Option (O)] menu to open the Y-S3: Input Level Negotiation window. The current input level (Input Level (dBu)) for each array and the attenuator settings for each amplifier connected to the speakers in the array are displayed in the Current column. The highest level of those displayed appears in bold. Click to standardize all related figures to this level. Y-S3 adjusts the amplifier attenuators at the same time so that the output to all speakers remains the same. This is useful when working with smaller mixers that are not equipped with multiple output busses. Before adjusting the input level After adjusting the input level 53 Yamaha Sound System Simulator Y-S3 Owner’s Manual V3.0 10. General Theory General calculation methods • • • • • • • • Y-S3 computes the speaker array response at the receiving point or audience area. The responses are computed by combining the responses from each speaker based on a geometrical simulation. Each speaker response is computed using measured directional impulse responses. First by selecting the impulse response for the corresponding direction based on the relationship between the receiver point and the speaker position, and then considering the effects of attenuation by distance, air absorption, amplifier type, system attenuation, and processor settings (EQ, delay). There are two methods of combining responses: a method that considers the interference and a method that is based on the summing of energy and not taking the interference into account. The response is limited to direct sound. Calculations are performed as for a free sound field without any reflections. The sound pressure level is calculated assuming sine wave or pink noise input to the system. There are two types of pink noise: band-pass filtered noise for the “Swept Band Noise” option or overall noise for the “Full Band Noise” option. The response for the two channels used in auralization is computed by first convolving the head-related transfer function (HRTF) of the directions corresponding to each speaker’s response, and then combining these responses. Auto setting methods • • 1. • • • 2. • • • • • There are two auto setting functions. “Auto layout” selects the appropriate speakers for the current room configuration, and “Auto tuning” determines the parameters (Angle, EQ, Amp type, Input Level and Attenuation) for each speaker. The results for each function are only rough estimates, and adjustments or modifications will be necessary for either method. Calculations are made based on the following theory. Auto layout Y-S3 selects the speaker type that is appropriate for the configuration of the room, its area, and the dimensions of the floor. Speaker positioning is conducted in accordance with the speaker arrangement methods (Center, Center + Side, Side) while considering the ceiling height of the room. Angles are set to default: Pan and Rot = 0 degrees, Tilt = 30 degrees and Splay Angle = minimum. Auto tuning Y-S3 sets speaker parameters for each speaker array. Y-S3 decides the speaker angles (Pan, Tilt and Splay Angle) to minimize the standard deviation of the sound pressure level within the area that is selected by the user as the coverage of the speaker array. When computing angles, the proper setting is selected from among the conditions in which all of the target points of the speaker composing the speaker array are within the selected cover area. Y-S3 decides the EQ and gain for each speaker so that the frequency responses are flat and their levels match the required SPL set by the user at the target points of each speaker that composes the speaker array. (Note 1: In auto tuning, since sound pressure level calculations at axis points are computed based on the summing of energy, peaks/dips from interference are not corrected. Note 2: Delay is not tuned automatically. All the delays are set to 0 ms after auto tuning.) In the level adjusting, Y-S3 first decides the necessary output power for each speaker referring to the required SPL. Then, Y-S3 decides the attenuation level to adjust the necessary power difference between the speakers in one speaker array. Finally, Y-S3 decides the input signal level from the necessary output power and amplifier gain. 54-
