Notice of external microphone usage
If you connect external microphones with “AUDIO 1 IN” or “AUDIO 2 IN”, you need to use Mic Mixer
and adjust its output level to line level, and this output should be inputted to “AUDIO 1 IN” or “AUDIO 2
IN”.
Adjust the audio level by watching the level meter displayed on the monitor to prevent level clipping. The
level meter can be displayed by setting “On” of “Setup →Home Menu 3 →Audio Level Meter”.
When “AUDIO 1 IN” and “AUDIO 2 IN” are used as AUX which can be selected in Setup menu (Setup
→Audio 1 →Audio Input), up to 22 kHz input signal can be passed through, but echo canceling function
cannot be used.
When “AUDIO 1 IN” and “AUDIO 2 IN” are used as MIC which can be selected in Setup menu
(Setup →Audio 1 →Audio Input), echo canceling function can be used (but input frequency is
limited.).
For details of Menu settings, refer to “To set up audio input and echo canceller” in 2-2-2.
Adjusting the volume from the remote party’s audio by viewing the volume level of the
Communication System and adjusting the volume on the TV monitor
Before adjusting the volume on the TV monitor, set the volume on the Communication System to the
appropriate position.
1. To display the volume meter, confirm its setting. (Setup →Home Menu 3 →Volume)
2. Press the VOLUME [+]/[_] buttons on the remote commander to set the volume level, such that the
bar displayed on the screen is adjusted to the middle position.
3. Adjust the volume on the TV monitor so that you can clearly hear a remote party speaking.
n
Do not activate the TV’s surround sound feature as it may prevent the echo canceller of the Commu-
nication System from functioning properly and thus produce an unexpected sound. During communi-
cation, set the volume on the Communication System to the appropriate level. Do not adjust the
volume on the TV monitor.

Audio output delay setting
Using the Lip Sync function closely synchronizes the audio and video signals. Even with the Lip Sync
function, however, there still may be a slight time lag, but this can be eliminated by setting a value in
“Audio Output Delay Setting”.
Note that, when the audio signal is fed to an audio system other than that built into the video display, even
using Lip Sync function will not be eliminate the time lag between the audio and video. The time lag can
also be eliminated by setting a delay in “Audio Output Delay Setting”. “Default” is that value with which
the audio is almost synchronized with the video. You can select “Default”, “Default ?50 ms”, and “De-
fault ?100 ms”. When you select “Custom”, an audio output delay between 0 ms and 500 ms can be set as
an absolute delay (Ver.2.01 and later), which has no relation to the Default value.
Audio input delay setting
When there is a time lag between the input audio and input video, a delay can be set in “Audio Input
Delay” to adjust the audio to the video.
An identical delay is set for all the microphones and all the external lines of the Communication System.
After setting up the audio and video system to operate with the Communication System, setting “Audio
Input Delay”, but then disconnecting the audio and video system from the Communication System,
restore the original values or set the “Default” value.
“Audio Delay from Video Picture at Remote Party” contains “Audio Input Delay” set for the local party
and the “Audio Output Delay” set for the remote party. The optimum “Audio Output Delay” setting is
adjusted for each remote party according to the individual usage circumstances, so it is recommended to
use the “Default” value for “Audio Input Delay Setting”.
