Up to two external microphones such as a handheld microphone or pin microphone can be connected to the product.
If you want to amplify the sound in your location when having a conversation with the remote location, connect an
external microphone.
A wireless handheld microphone or wireless pin microphone can also be used.
■Preparation
To connect an external microphone, use a microphone with a cable that has an RCA pin plug that can be connected to
the YVC-1000MS.
■Connection
The following example shows a case in which one handheld microphone is connected to the product.
An external microphone can be used together with the microphone supplied with the product, or an optional
microphone (YVC-MIC1000EX).
•The sound picked up by external microphones is output not only in the remote location but also from the built-in speaker.
When external speakers are used, the sound is also output from them.
•The video conference system can be connected to an audio input terminal that has no external microphone connected to it.
For details, refer to "Connecting to a video conference system using audio cables" (page 23).
■Setting with "YVC-1000 Configurator"
When using external microphones, connect the product to a PC or a Mac on which the "YVC-1000 Configurator"
application has been downloaded, to enable the external microphones. Also, adjust the volume or tone to suit the type
of external microphone you are using, or your environment.
For details, refer to "When external microphones are connected:" (page 38).
If you hear any feedback, place the external microphones away from the speakers, or reduce the sensitivity of the
external microphones using "YVC-1000 Configurator".
The settings configured with "YVC-1000 Configurator" are saved in the product, therefore it is not necessary to keep the PC
or Mac connected after the settings have been completed. The configured settings continue to be saved even after the product
has been turned off.

Up to two speakers with built-in amplifiers can be connected to the product as external speakers. When using the
product in a layout or a multi-participant conference that cannot be covered by only the built-in speaker, use external
speakers to extend the area where playback sounds can be heard.
Use external speakers with a low latency and distortion.
If you use external speakers with a high latency or distortion, it may cause an echo phenomenon in the remote location.
■Preparation
Prepare audio cables (RCA pin plug) to suit the number of external speakers to be connected.
•Speakers with a built-in amplifier may have a different shape of the audio input terminal depending on the model. Use an
audio cable with the plug shape that matches the shape of the audio input terminal for each of your speakers. The product
must be connected to an RCA pin plug regardless of the type of the plug to be connected to each speaker.
•Monaural signal is output as an audio signal from both external speaker terminals.
■Installation
Place all external speakers 1 m to 20 m (3.3 ft to 66 ft) away from all microphones.
The following figure shows an example of installation of two external speakers and one microphone.
If external speakers are too close to or far from
microphones, it may cause an echo phenomenon in the
remote location.
■Connection
Connect the product to external speakers using audio cables.
The following example shows a case in which two external speakers are connected.
Do not connect external speakers to the audio output terminals.

The automatic audio tuning function automatically measures acoustic features of the location the product is installed in
as well as acoustic conditions such as positions to place the microphone and speaker, and tunes the acoustic settings to
the optimal level to suit the environment the product is used in.
If you have changed the installation location or installation position of the product, or if you have changed the number of
microphones or connected an external speaker, be sure to carry out automatic audio tuning before using the product.
The result of automatic audio tuning continues to be saved even after the power has been turned off.
■Preparation
Make the following preparation to normally carry out the automatic audio tuning.
•Place the Control Unit, microphones, and external speakers (if used) as used actually, and make connections.
•Adjust the speaker volume so that four or more lamps light up on the level indicator.
■Carrying out automatic audio tuning
While automatic audio tuning is active, the voice guidance is replayed to explain the procedure for carrying out automatic
audio tuning.
1Hold down the call button ( ) for 2
seconds or more.
The call button ( ) flashes orange, and automatic
audio tuning starts.
2The acoustic measurement starts.
A white noise (hissing sound) is replayed from
speakers as the measurement sound. During
measurement, stay away from the devices and keep
quiet.
3The acoustic settings starts.
This carries out the optimization of adaptive echo
canceller settings and automatic room EQ settings,
the latency compensation of external speakers, and
the calibration of frequency characteristics.
If "MODE" is set to "PA MICROPHONE" using
"YVC-1000 Configurator", the latency compensation of
external speakers will not be enabled.
4Automatic audio tuning ends.
When automatic audio tuning ends, the result is
notified using the voice guidance.
Also, the result is indicated by the color and lit/not
lit status of the call button ( ).
Each indicator status has the following meaning.
•Lit (Green): Normal end
•High-speed flash (Orange): Abnormal end
•Automatic audio tuning cannot be started in the following
cases.
-The speaker volume is low (three or less lamps light up
on the level indicator).
-No microphone is connected.
•If the following operation or status is detected during the
acoustic measurement, automatic audio tuning is stopped.
-The call button ( ) has been pressed.
-When the product is connected to a PC or a Mac using
a USB cable, the speaker volume has been operated
through a PC or a Mac.
-A microphone cable has been unplugged.
-When only external speakers are enabled, no sound is
output from them.
