local speaker as well. If Auto is selected, the audio from the VCR will only be heard when
VCR is selected as video source.
Mix Mode
Auto
The adjustment of each microphone signal is done automatically to obtain the
best possible audio and minimize the background noise.
Fixed
Fixed will maintain a constant weighting of all microphones.
VCR Ducking
If VCR Ducking is activated, the VCR audio level will be attenuated if someone talks into the
microphone or at the far end.
Level Settings
It is possible to adjust the audio input levels according to which external audio equipment is
connected. The on-screen audio level indicator will make it easier to set the correct input level
settings. The input level should be adjusted so that the average level reaches the preferred
level marker. The audio inputs are adjustable in steps of 1.5 dB from 0 dB to 22.5 dB.
The default levels for Mic 1,2 and 3 are set for use with an Audio Technica AT871R or
AT841R microphone in an average videoconferencing room. The gain can be adjusted
correctly for a wide range of microphones.
A few examples of microphone levels are:
Audio Technica
AT871R
+3dB (default)
Audio Technica
AT851R +7dB
TANDBERG Audio
Science +19.5dB
Audio inputs 4, 5 and 6 are set to a default level which is adhered to by most manufacturers
of audio-visual equipment and is a level at which most audio-visual equipment (CD-players,
VCRs or DVDs) will work.
