Both unbalanced phone type (+4 dB/10 kΩ) and balanced XLR type (+4 dB/600 Ω) jacks are provided. Use the LINE SOURCE switch to select the signal that is sent to the LINE OUT jack. As the unit is equipped with an output limiter and speaker simulator (can be switched ON/OFF), and the output level of these jacks is controlled by the LEVEL control, these jacks can be used to send a line level signal to a mixing console or an additional amplifier.  Panel Controls and Connections @0 Line Out Source Switch (LINE SOURCE: THRU/PRE EQ/POST EQ) This switch is used to select the signal that is delivered from the LINE OUT jack. THRU ........... Delivers the signal received via the INPUT jack without alteration. Select this setting when connecting to a DI (Direct Injection) box. PRE EQ ....... Delivers the signal before it has been processed by the tone controls (the Sound Type is active). This setting can be used when separate EQ settings are required for speaker and line outputs. POST EQ ..... Delivers the signal after it has been processed by the tone controls. This setting can be used when you want the line signal processed with the same EQ setting as the speaker. * The FX LOOP is active on both PRE EQ and POST EQ signals. @1 Speaker Simulator Switch (SP SIM: OFF/LINE/ON) This switch is used to switch the Speaker Simulator circuit ON/OFF. When the Speaker Simulator is activated, this special circuit adds the live characteristics of a speaker to the line out signal and headphones output. This feature is also effective when you want to produce a distorted sound with the tweeter level raised. The sound created with the Speaker Simulator is optimized to compliment the selected Sound Type. OFF .............. Deactivates the Speaker Simulator on LINE OUT, SPEAKER, and PHONES jack signals. LINE ............. Activates the Speaker Simulator on LINE OUT, and PHONES jack signals only. ON ................ Activates the Speaker Simulator on LINE OUT, SPEAKER, and PHONES jack signals. * The Speaker Simulator can only be applied to the LINE OUT jack output when the @0 Line Out Source Switch is set to “POST EQ”. @2 Output Limiter Switch (OUTPUT LIMITER: ON/OFF) This switch is used to switch the Output Limiter circuit ON/OFF. When set to the ON position, the limiter suppresses the signal if it exceeds the threshold before sending it to the SPEAKER jack and LINE OUT jack. OFF .............. Deactivates the Limiter on both LINE OUT and SPEAKER jack signals. ON ................ Activates the Limiter on both LINE OUT and SPEAKER jack signals. @3 MIDI OUT Jack Connect this jack to the MIDI IN jack on an external MIDI device that can save MIDI data (such as a MIDI data filer, etc.), and save patch data from the BBT500 to an external device. (→ pg. 17: MIDI Bulk Out) Also, when MIDI Merge is set ON, MIDI data received from an external MIDI device via the MIDI IN jack is transmitted from the MIDI OUT jack without alteration. (→ pg. 17) @5 Speaker Jacks (SPEAKER 1, 2 (EXT)) Two Speaker Jacks are provided for connecting speaker systems. The amp’s internal speaker (4 Ω) is connected to the SPEAKER 1 jack. The SPEAKER 2 (EXT) jack can be used to add an external speaker(s). Also, if necessary, you can disconnect the internal speaker to connect 2 external speakers directly to the amp. The two speaker jacks are connected in parallel. When external speakers are used, make sure the speakers meet the following requirements. ● When using a single SPEAKER Jack (1 or 2) Please use a system that complies with one of the following requirements. • The total impedance* of the circuit should never be less than 2Ω. • A 2Ω speaker system must have a power handling capability of 500W or greater. • A 4Ω speaker system must have a power handling capability of 250W or greater. • An 8Ω speaker system must have a power handling capability of 125W or greater. ● When using both SPEAKER Jacks (1 & 2) Please use a system that complies with one of the following requirements. • The total impedance* of the circuit should never be less than 2Ω. • A 4Ω speaker system must have a power handling capability of 250W or greater. • An 8Ω speaker system must have a power handling capability of 125W or greater. To obtain optimum performance from the amplifier, we recommend connecting the internal speaker to the SPEAKER 2 jack, and using the SPEAKER 1 jack to connect an external speaker (set) with a 4Ω impedance and power handling capacity of 250W or greater. * See page 10 for more information on total speaker impedance. * For U.S. and Canadian models only To protect against electromagnetic waves, attach the supplied Clamp Filters to the cables connecting the amplifier’s SPEAKER 1, 2 (EXT) jacks to the speakers. (→ pg. 10) @6 Tweeter Level Control (TWEETER LEVEL) This controls the built-in tweeter speaker’s output level (mainly high frequencies above 4 kHz). @7 Power Connector (AC IN) Connect the supplied power cable to this terminal to supply the unit with power from an AC power outlet. When connecting the power cable, make sure the amplifier’s POWER switch is turned OFF. @4 MIDI IN Jack Connect this jack to the MIDI OUT jack on MIDI Foot Controller, etc., to select patches, control volume, etc., with the MIDI Foot Controller. (→ pg. 16) Also, patches that have been saved to an external MIDI device can be loaded into the BBT500’s internal memory. (→ pg. 17: MIDI Bulk IN) 9  Panel Controls and Connections * Total Impedance Whenever two or more speaker cabinets are connected to the unit, consideration must be given to the total impedance of the speaker system. Normally, a speaker cabinet has an impedance of 4, 8 or 16Ω. But when two or more speaker cabinets are used together, the total impedance will change according to the manner in which the cabinets are connected. ● Connecting in a Series Total impedance = 1st Speaker + 2nd Speaker + 3rd Speaker … Connecting three 4Ω speaker cabinets in a series as shown below, results in a total impedance of 12Ω. As the BBT500-115’s and BBT500-110’s two speaker jacks are connected in a parallel circuit inside of the amplifier, adding a 4Ω external speaker to the 4Ω internal speaker will result in a total impedance of 2Ω. So in order to maintain a minimum impedance of 2Ω, an external speaker with an impedance of 4Ω or greater must be used. ● Connected in Parallel Total impedance = Connecting three 4Ω speaker cabinets in a parallel configuration as shown below, results in a total impedance of about 1.3Ω. 4 4 4 External Speaker Greater than 4 Ω ● Attaching the Clamp Filter Internal Speaker 4Ω (For U.S. and Canadian models only) To protect against electromagnetic waves, attach the supplied Clamp Filter to the cable connecting the bass guitar to the amplifier’s INPUT jack, and to the cable connecting the amplifier to an external speaker. * The cable connecting the internal speaker (SPEAKER 1 jack) is fitted with a Clamp Filter at the factory. * When attaching the clamp filter, wrap the cable once around the clamp filter as close to the BBT500 unit as possible. Cable Clamp Filter 10 Clamp Filter  Operating Instructions Sound Setting Getting sound output 1 First, make sure that the POWER switch is switched OFF, then connect your bass to the INPUT Jack on the front panel. 2 Rotate the OUTPUT knob fully to the left and then switch the POWER switch ON. To protect the speakers, make sure that the OUTPUT knob is set to “0” whenever switching the POWER switch ON or OFF. 3 First, set the INPUT LEVEL knob to its 12 O’clock position, then while playing the bass, gradually increase the GAIN, MASTER, and OUTPUT knobs to adjust the sound. 4 Once the system is producing sound, set the input level as described in the “Adjusting the Input Level” section below. When the power is switched ON, all control knobs function as labeled on the panel and described below. All lamps on the display above the control knobs and switches are unlit. Rotate the SOUND TYPE knob to select a sound type, then use the Tone Control knobs to shape the sound. Before selecting a sound type, first set the GAIN through TREBLE control knobs to their center positions then try out the different Sound Types. Also, the COMP knob is used to adjust the compressor’s compression ratio. The compressor automatically balances the differences between loud and soft levels when playing. Rotate the knob to the right to increase the amount of compression. q w e r t y u i o !0 !1 q INPUT LEVEL: Sets the Input Level Adjusting the Input Level The INPUT LEVEL control optimizes the signal received from the bass for use with the amplifier, to produce wide dynamic range and rich tone. A poorly adjusted level results in noise, feedback, a cutup sound, etc. * Since output levels vary from instrument to instrument, you will need to readjust the input level to match the instrument’s output level whenever you change instruments. 1 Rotate the volume control on your bass to its maximum level and play loudly while rotating the INPUT LEVEL knob. An ideal level is attained when the green indicator is lit. 2 Continue to rotate the INPUT LEVEL knob to the right making sure the red indicator does not light. As long as the red indicator does not light, rotate the knob fully to the right. w SOUND TYPE: Selects the Sound Type (11 types) FLAT ............ A clean tone with all frequencies set flat. This setting also works well with an upright bass or an electric-acoustic bass. TUBE ........... A clear and warm tube type sound. This setting also works well with an upright bass or an electric-acoustic bass. SOLID ......... A fat solid-state type sound R & B ........... A fat R & B type sound VINTAGE ..... A vintage tone with warm mid frequencies MODERN .... A modern sound with rich low-end and bright high-end CLASSIC ..... Rock bass sound HEAVY ........ A heavier sound than the CLASSIC setting DRIVE ......... Overdrive bass sound DIST ............ Distortion bass sound FUZZ ........... Fuzz bass sound e COMP: Compression Ratio (1.0 to ∞, 16 steps) This adjusts the compressor’s compression ratio and output levels simultaneously. As the value increases, so does the amount of compression applied to signals that exceed the threshold level (→ pg. 14). r GAIN: Pre-Amp Gain (0 to 10, 0.1 step) Set the knob so that the red indicator does not light. t MASTER: Master Volume (0 to 10, 0.1 step) y BASS: Bass Frequency (-15dB to +15dB, 0.2dB step) u LOW MID: Low Mid Frequency (-15dB to +15dB, 0.2dB step) i MIDDLE: Middle Frequency (-15dB to +15dB, 0.2dB step) o HIGH MID: High mid Frequency (-15dB to +15dB, 0.2dB step) !0 TREBLE: Treble Frequency (-15dB to +15dB, 0.2dB step) !1 OUTPUT: Sets the output level HINT Using the OUTPUT and MASTER Controls Both knobs can be used to control the overall volume however, the MASTER knob is the preamplifier’s master volume and its setting is saved in memory. The OUTPUT knob is the power amplifier’s output volume and its setting is not saved in memory. Use the MASTER knob to set individual volume settings of patches saved to memory, and use the OUTPUT knob to set the output volume level produced by the speakers. 11  Operating Instructions Storing and Recalling Patches After creating a sound that you like, you can store its settings in the unit’s internal memory. Sound setting data (individual knob settings) is called a Patch. Saving a patch to the unit’s internal memory is called Store. The BBT500 provides five memory locations for storing patch data. Patch data in the memory is stored even when the power is switched OFF, and can be recalled at any time by pressing the patch’s corresponding switch. Take note that unless the changes are saved to memory, any changes made to the patch will be lost when another patch is selected or when the power is switched OFF. Storing a Patch After creating a sound you want to keep for later use, press and hold any one of the Memory Switches (1-5) until all of the front panel indicators light. Ex.) Press and hold Memory Switch [1] until all indicators light. However, if the value set in the patch is different than the knob’s actual position, the patch’s value will flash in the display but it will not change, nor will the sound, even though you are turning the knob. For more information on this situation, refer to the “Knob Position and Settings” section below. ● Knob Position and Settings When a patch is recalled from memory, etc., it may be that the knob’s actual position differs from the value set in the recalled patch. In this case, the BBT500 is programmed to flash the patch’s value on the display without changing it or the sound until the knob’s position corresponds to the value in the recalled patch setting. If the display flashes when rotating the knob, continue rotating the knob until its position matches the flashing value. When the position and value match, the value will stop flashing on the display and change as the knob is turned. Ex.) If the GAIN knob is pointing at the “3 o’clock” position and a patch with a GAIN setting of 4.0 is recalled. * INPUT LEVEL and OUTPUT LEVEL settings are not stored in memory. Recalling a Patch To use one of the patches stored in memory, just press the Memory Switch [1]-[5] to which the data is stored. The indicator of the selected Memory Switch lights. Ex.) Recalling the patch stored to Memory Switch [2]. The value “4.0” flashes on the display but rotating the knob from the “3 o’clock” position to the “11 o’clock” position does not change anything. As the knob goes past the “11 o’clock” position and its position matches that of the value, the value will then stop flashing and start changing according to the knob’s position. ● The Useful “Undo” Function After you recall or store a patch, the value for each knob will appear in the display when the knob (COMP - TREBLE) is used. Setting Value 12 Press and hold the [MANUAL] switch activates the “Undo” function, which returns settings to the condition they were in prior to pressing a Memory Switch [1]-[5] or the [MANUAL] switch. This function is useful in cases such as: You’ve just made some changes to the patch saved in Memory Switch [1] but pressed Memory Switch [2] before you could save the changes to memory. Press and hold the [MANUAL] switch to return the settings to the same condition they were in before you pressed Memory Switch [2]. In the same manner, you made some changes to a patch but pressed the [MANUAL] switch before you could save those changes to memory. Press and hold the [MANUAL] button to restore your changes.  Detailed Parameter Settings The BBT500 also features more precise settings for defining the frequencies for each of the Tone Control knobs, operating the Compressor and Noise Gate, or setting the Blend Level of the effect loop, etc. To access these settings, press the [FUNCTION] switch and use the four Modes described below. • Amp Mode In this mode, each knob functions in the manner it is labeled on the front panel. • Equalizer Mode This mode is used to set the 1-band parametric equalizer and the center frequency for each of the Tone Controls (Bass – Treble). Amp Mode Each knob functions in the manner it is labeled on the panel. In the Amp Mode, the knob’s value (or patch’s setting value) is shown on the display when the knob is turned. * After the BBT500’s power is switched ON or the [MANUAL] switch is pressed, nothing is shown in the display until a Memory is recalled, or a mode other than the Amp Mode is selected. Enter the Amp Mode using one of the following methods. • The Amp Mode is the default mode when the BBT500’s power is switched ON. • Compressor Mode This mode is used to set the Compressor’s blend level, noise gate level, and effect loop. • Press the [MANUAL] Switch to enter the Amp Mode. • Utility Mode This mode is used to set the crossover filter, and individual MIDI settings. • In the Equalizer, Compressor, or Utility Mode, press the [FUNCTION] switch. Individual settings in the Amp Mode, Equalizer Mode, and Compressor Mode are saved when patch data is saved to the unit’s memory. Individual parameter settings in the Equalizer Mode and Compressor Mode are set to their default values when the power is switched ON. Individual settings in the Utility Mode are saved when exiting the Utility Mode, and they are retained even if the power is switched OFF. • Press a Memory Switch [1] – [5] to recall a patch. Or, press and hold a Memory Switch to save a patch to memory. ● How Knobs Function in the Amp Mode The knob’s value is shown on the display when the knob is turned. q w e r t y u i o !0 !1 Each control knob’s function in the Amp Mode is the same as described in the “Sound Setting” section (→ pg. 11). q INPUT LEVEL: Sets the Input Level w SOUND TYPE: Selects the Sound Type (11 types) e COMP: Compression Ratio (1.0 to ∞, 16 steps) r GAIN: Pre-Amp Gain (0 to 10, 0.1 step) t MASTER: Master Volume (0 to 10, 0.1 step) y BASS: Bass Frequency (-15dB to +15dB, 0.2dB step) u LOW MID: Low Mid Frequency (-15dB to +15dB, 0.2dB step) i MIDDLE: Middle Frequency (-15dB to +15dB, 0.2dB step) o HIGH MID: High mid Frequency (-15dB to +15dB, 0.2dB step) !0 TREBLE: Treble Frequency (-15dB to +15dB, 0.2dB step) !1 OUTPUT: Sets the output level 13  Detailed Parameter Settings Equalizer Mode Compressor Mode The Equalizer mode lets you make settings for the internal 1-Band Parametric Equalizer, and set the center frequency (or in the case of the TREBLE control knob, its cutoff frequency) for each of the panel’s Tone Controls (BASS – TREBLE) in the internal five-band equalizer. The Compressor Mode provides settings for the Compressor, Noise Gate, and Blend Level for the effect loop. To enter the Equalizer mode, press the [FUNCTION] switch. Knob functions are displayed in the bottom row of the panel display above the knobs. ● How Knobs Function in the Equalizer Mode The knob’s value is shown on the display when the knob is turned. q w e The function of each knob is displayed here. r t y u i o !0 !1 To enter the Compressor Mode, press and hold the [FUNCTION] switch until the knob functions are displayed in the upper row of the panel display above the knobs (the row above that used by the Equalizer Mode). ● How Knobs Function in the Compressor Mode The knob’s value is shown on the display when the knob is turned. q w e r t The function of each knob is displayed here. y u i o !0 !1 q INPUT LEVEL: Sets the Input Level q INPUT LEVEL: Sets the Input Level w SOUND TYPE: No function. w SOUND TYPE: No function. e COMP (PEQ F): Sets the center frequency of the 1-band parametric equalizer (20Hz to 20.0kHz, 255 steps) e COMP (RATIO): Compression ratio (1.0 - ∞, 16 steps) *operates the same as COMP in the Amp Mode. r GAIN (THRSLD): Compressor threshold level (-54dB to 0dB, 1dB step) r GAIN (PEQ Q): Sets the bandwidth of the 1-band parametric equalizer. (0.1 to 20.0, 255 steps) t MASTER (PEQ G): Sets the gain level of the 1-band parametric equalizer. (-15dB to +15dB, 0.2dB step) y BASS (FREQ): Sets the center frequency of the BASS control knob. (20Hz to 320Hz, 255 steps) u LOW MID (FREQ): Sets the center frequency of the LOW MID control knob. (80Hz to 1.28kHz, 255 steps) i MIDDLE (FREQ): Sets the center frequency of the MIDDLE control knob. (250Hz to 4.00kHz, 255 steps) o HIGH MID (FREQ): Sets center frequency of the HIGH MID control knob. (500Hz to 8.00kHz, 255 steps) !0 TREBLE (FREQ): Sets the center/cutoff frequency of the TREBLE control knob. (1.25kHz to 20.0kHz, 255 steps) !1 OUTPUT: Sets the output level Sets the signal level from which the compressor will activate. Compression is applied to signals that exceed this level. t MASTER (ATTACK): Compressor attack time (0msec to 120msec, 1msec step). Sets the amount of time required for application of the compressor from the time the signal exceeds the threshold. When a slow attack time is set, the beginning of the attack will not be compressed. y BASS (RELEASE): Compressor release time (5msec to 42.3 sec, 160 steps). Sets the amount of time required for the compressor to switch off after the signal goes below the threshold level. This smoothes gain changes to keep the sound natural. u LOW MID (C. GAIN): Compressor gain (0dB to 18dB, 0.1dB step) This parameter works in conjunction with the compressor ratio setting which is set with the e COMP (RATIO) control knob. In other words, gain is automatically adjusted along with amount of compression applied to the signal. If the Ratio = “1.0”, Gain = “0”. If the Ratio = “∞”, Gain = the setting determined with the control knob. i MIDDLE (KNEE): Compressor knee (Hd (Hard), 1, 2, 3, 4, 5) r PEQ Q + Sets the depth of signal compression after the input signal exceeds the threshold level. When set to Hd (hard), compression starts soon with the ratio you have set. However, when set to 1-5, compression startup is gradual, creating a more natural sound (soft knee compression). 0.1 0 Frequency t PEQ G Gain 20 – o HIGH MID (N. GATE): Noise gate threshold level (OFF, -53dB to 0dB, 1dB step) When the input signal’s level falls below this set level, the noise gate activates cutting off the signal. !0 TREBLE (BLEND): Blend level between the effect loop’s RETURN signal e PEQ F and the dry signal (the sound created in the BBT500) (0% (Return 0%, Dry 100%) to 100% (Return 100%, Dry 0%)). !1 OUTPUT: Sets the output level 14  Detailed Parameter Settings Utility Mode Crossover Filter The Utility Mode provides settings for the Crossover Filter and MIDI. These settings are saved internally when you exit the Utility Mode and kept even when the amplifier’s power is switched OFF. By connecting two BBT500s as shown in the illustration below, you can create a bi-amplified system, where one amplifier is used to drive high frequencies and a second amplifier drives low. This system uses the amplifier’s onboard crossover filter (LPF or HPF) to determine the range of frequencies that each amplifier will deliver. ● Entering the Utility Mode To enter the Utility Mode, from any mode press and hold the [FUNCTION] switch for more than 3 seconds, until “utL” appears on the display. ● Setting the Crossover Filter 1 Press and hold the [FUNCTION] switch for more than three seconds (until “utL” appears on the display) to enter the Utility Mode. 2 Rotate the COMP knob to set the Crossover filter’s cutoff frequency. * Range of cutoff frequency L10 (LPF 100Hz) to L00 (LPF 1000Hz), byP (Bypass), h10 (HPF 100Hz) to h00 (HPF 1000Hz), 93 steps ● How Knobs Function in the Utility Mode In the Utility Mode, only the INPUT LEVEL, OUTPUT, and COMP knobs function. All other knobs (SOUND TYPE, GAIN - TREBLE) have no function. • INPUT LEVEL: Sets the Input Level • OUTPUT: Sets the output level When using a bi-amplified system, make sure that the INPUT LEVEL control knob on the second BBT500 is set to its minimum level. Ex.) Operating a bi-amplified system in which the crossover filter on the first amplifier is set to h50 (HPF 500Hz) to produce high frequencies, and the crossover filter on the second amplifier is set to L50 (LPF 500Hz) to produce low frequencies. • COMP: Sets the cut off frequency of the crossover filter When the COMP knob is used (when setting the crossover filter), the setting’s value is shown in the display. Other than that, only utL appears on the display. Use the [MANUAL] switch and Memory Switches [1] through [5] to set individual MIDI settings. (→ [MIDI Settings] pg. 16) Individual MIDI Settings First amplifier (HPF 500Hz) Bass When the COMP knob is used (when setting the crossover filter), the setting’s value is shown in the display. Other than that, only utL appears on the display. TUNER OUT INPUT * Set to “h50” with the COMP control knob Second amplifier (LPF500Hz) Produces higher frequencies above 500Hz INPUT q w e * Set the INPUT LEVEL to its minimum level * Set to “L50” with the COMP control knob Produces low frequencies up to 500Hz 15  Detailed Parameter Settings MIDI Settings The BBT500 is MIDI* compatible and equipped with MIDI IN and MIDI OUT jacks. * What is MIDI? The acronym for Musical Instruments Digital Interface, MIDI is a worldwide standard communication interface that allows MIDI compatible musical instruments, computers, and other MIDI devices to share musical information and control one another regardless of instrument type or maker. 3 Create a Program Change Map*. (Default → Program Change No: Memory No = 1:1, 2:2, 3:3, 4:4, 5:5, 6:1, 7:2, 8:3 …) * What is a Program Change Map? A Program Change Map assigns a program change number (received via MIDI) to a memory number. For example, when the BBT500 receives “Program Change Number 1” from an external MIDI device, it will recall memory number “3”. This is also called a Program Change Table. With MIDI functions you can do things like select a patch from the BBT500’s memory using an external MIDI device like the MFC10 Yamaha MIDI Foot Controller, etc. You can also backup data by sending the contents in the unit’s memory to a device that is capable of saving MIDI data (Yamaha MDF3, etc.). 3-1 Press and hold the [FUNCTION] switch for more than 3 seconds (until “utL” appears on the display) to enter the Utility Mode. ● Selecting a Patch with MIDI 3-2 While holding the [MANUAL] switch, press Memory Switch [1]. The currently assigned MIDI program change number appears on the display (after a few seconds, the display will return to “utL”). 1 Using a MIDI cable, connect the MIDI IN jack on the BBT500 to the MIDI OUT jack on the external MIDI device. * Use only a standard MIDI cable that is less than 15 meters in length. Use of a longer cable can result in trouble such as abnormal operation, etc. Receive Program Change Number MIDI Cable BBT500 Rear Panel MIDI IN MIDI OUT STATUS DATA/CTRL BANK MSB/MAX BANK LSB/MIN TOGGLE ON-OFF /NUMBER OF PGM 8.8.8. DEC ±10 INC /NO /YES MEMORY EDIT PC EDIT WRITE /EXIT 3-3 Use Memory Switches [1] and [2] to set the program change number (1-128) that is received by the BBT500. Use Memory Switch [2] to increase the value and Memory Switch [1] to decrease the value. 3-4 While holding the [MANUAL] switch, press Memory Switch [2]. The memory number that will be recalled when the program change number that was set in step 3-3, appears on the display. (After a few seconds, the display will return to “utL”). External MIDI Device 2 Set the MIDI receive channel on the BBT500 and the MIDI transmit channel on the external device to the same MIDI channel. (Default channel: 1) * MIDI data can not be transmitted or received if the MIDI channels are not properly matched. 2-1 Press and hold the [FUNCTION] switch for more than three seconds (until “utL” appears on the display) to enter the Utility Mode. 2-2 While holding the [MANUAL] switch, press Memory Switch [3]. The currently assigned MIDI receive channel appears on the display (after a few seconds, the display will return to “utL”). Memory Number 3-5 Use Memory Switches [1] and [2] to set the memory number (1-5) that corresponds to the program change number received by the BBT500. Uses Memory Switch [2] to increase the value and Memory Switch [1] to decrease the value. 3-6 If necessary, repeat steps 3-2 through 3-5. 3-7 Press the [FUNCTION] switch to enter the Amp Mode. MIDI Receive Channel 4 2-3 Use Memory Switches [1] and [2] to set the MIDI receive channel (1-16, ALL, oFF). Use Memory Switch [2] to increase the value, and Memory Switch [1] to decrease the value. * “ALL” is set to Omni On. When “oFF” is set, MIDI data will not be received. 16 Now, when a program change number transmitted from an external MIDI device is received by the BBT500, it will recall the corresponding memory number that is set in the program change map you just created will be recalled. * Refer to the Owner’s Manual that came with your MIDI device on how to receive or transmit program change data.  Detailed Parameter Settings ● MIDI Merge Settings 4 If you want MIDI signals received by the BBT500’s MIDI IN jack transmitted without alteration to other MIDI devices connected to the BBT500’s MIDI OUT jack, set the MIDI Merge to “on”, if not, set it to “oFF”. 1 Press and hold the [FUNCTION] switch for more than three seconds (until “utL” appears on the display) to enter the Utility Mode. 2 While holding the [MANUAL] switch, press Memory Switch [4]. The current MIDI Merge setting appears on the display (after a few seconds the display will return to “utL”). MIDI Merge Setting Use Memory Switches [1] and [2] to set the type of data (1-5, ALL) to be sent with the Bulk Out operation. 1-5 ...... Sends only the data from the selected memory number. ALL ..... Sends all data in memory numbers 1-5 and Utility Mode settings. 5 Press Memory Switch [5] to carry out the Bulk Out operation. While the Bulk Out operation is in progress, all lamps on the unit will light. * The device number becomes the MIDI receive channel number (→ pg. 16). When the MIDI receive channel is set to “ALL” (Omni ON), the channel is set to 1. 6 Press the [FUNCTION] switch to enter the Amp Mode. ● About MIDI Control Changes 3 Use Memory Switches [1] and [2] to set MIDI Merge either “on” (Memory Switch [2]) or “oFF” (Memory Switch [1]). 4 Press the [FUNCTION] switch to enter the Amp Mode. You can use the MIDI Bulk Out operation to back up data saved in the BBT500 (data in memory 1-5 and Utility Mode settings) to a device that can save MIDI data (such as a Yamaha MDF3, etc.). Using a MIDI cable, connect the MIDI OUT jack on the BBT500 to the MIDI IN jack on an external MIDI device. * Use only a standard MIDI cable that is less than 15 meters in length. Use of a longer cable can result in trouble such as abnormal operation, etc. MIDI Cable BBT500 Rear Panel * With the exception of the Number 7 Control Change, the BBT500 does not recognize any other MIDI Control Change messages. * The Main Volume data will not change, even if a different memory number is selected. ● MIDI Bulk Out 1 You can control the overall volume of the BBT500 by connecting an external MIDI device’s MIDI OUT jack to the BBT500’s MIDI IN jack, and transmit Number 7 Control Change Messages (Main Volume) to the BBT500. MIDI IN * When the POWER is switched ON, the Main Volume data is set to its MAX value. * After the Main Volume data is changed, and the external MIDI device is disconnected, the pre-amp’s volume level may not be sufficient. If this case occurs, transmit a Control Change with a higher volume setting again, or switch the POWER OFF and then back ON. ● About MIDI Bulk In Using a MIDI cable, connect the MIDI IN jack on the BBT500 to the MIDI OUT jack on an external MIDI device to return data that has been stored on the external device, to the BBT500’s memory. This operation is referred to as MIDI Bulk In. * The device number becomes the MIDI receive channel number (→ pg. 15). When the MIDI receive channel is set to “ALL” (Omni ON), the channel is set to 1. When set to “oFF” (OFF) data will not be received. MIDI OUT * “Ld” appears on the display while receiving MIDI Bulk data. External MIDI Device 2 Hold the [FUNCTION] switch for more than three seconds (until “utL” appears on the display) to enter the Utility Mode. 3 While holding the [MANUAL] switch, press Memory Switch [5]. The type of data to be sent with the Bulk Out operation appears on the display (after a few seconds the display will return to “utL”). Type of data to be sent with the Bulk Out operation. ● Sending/Receiving MIDI Data Between Two BBT500s The MIDI Bulk In or MIDI Bulk Out operations can be used to copy memory or Utility Setup data in one BBT500 to another BBT500. ● Restoring the Factory Presets This operation clears the contents of the BBT500’s memory 1-5 and restores all parameters to their factory preset settings. While holding the [MANUAL] switch and Memory Switch [5], switch the POWER switch ON. 17  Air Flow The device utilizes a forced air cooling system, which cools the interior of the unit by drawing air through the front intake by the fan, which push the air out the back. Front view Rear view Intake Error Messages If an error occurs during operation, one of the following error message numbers will appear on the display. E1: MIDI Receive Buffer Full CAUSE: Too much MIDI data is being received by the BBT500 at one time. SOLUTION: Try reducing the amount of data being sent or, break the data into smaller blocks. E2: Communication Error. CAUSE: An abnormality is detected during MIDI communications. SOLUTION: Check all connections, etc. and try again. E3: Bulk Receive Check Sum Error. CAUSE: The check sum does not match the received MIDI bulk data. SOLUTION: Check all connections and data, and try again. E4: MIDI Receive Data Abnormality. CAUSE: An abnormality is detected in the received MIDI data. SOLUTION: Check all connections and data, and try again. Troubleshooting • No Sound → Is the power cord properly connected to the device? → Is the volume turned up on the instrument connected to the INPUT jack? → Are the INPUT LEVEL, GAIN, MASTER, OUTPUT control knobs set to “0”? → Check the Effect Loop’s BLEND setting (Compressor Mode: TREBLE control knob). Unless an external effector is connected to the device, raising the BLEND control will result in lowering the original sound. If the BLEND control is set to “100”, the original sound will not be produced. • Sound output is low → Is the volume turned up on the instrument connected to the INPUT jack? → Are the INPUT LEVEL, GAIN, MASTER, OUTPUT control knobs turned up? → Check the Effect Loop’s BLEND setting (Compressor Mode: TREBLE control knob). Unless an external effector is connected to the device, raising the BLEND control will result in lowering the original sound. If the BLEND control is set to “100”, the original sound will not be produced. → Check the Compressor setting. A low Threshold setting or a high Ratio setting will result in a lowered the output signal level. Also, a long release setting or low Compressor Gain setting will result in a lowered output signal level. 18 Cooling fan Exhaust  Specifications Power Amplifier Section Class-D power amplifier circuitry Output 250 W/4Ω (When used alone) 500 W/2Ω (Max output with external speaker connected) Speaker Section Speaker Power Handling Impedance BBT500-115 : 15” Woofer x1, Tweeter x1 BBT500-110 : 10” Woofer x1, Tweeter x1 250 Wrms 4Ω Preamplifier Section All digital signal processing Sound Type: 11 Presets 5-Band Semi Parametric Tone Controls (Variable Frequencies) Parametric Equalizer (PEQ, F, G, Q) A/D Conversion 24 bit D/A Conversion 24 bit Effect Section Compressor RATIO, THRSLD, ATTACK, RELEASE, C.
