4.5.1 Inputs
Mic and Audio input L-R (VCR Left/Right)
By default, all inputs are enabled. Just plug in an audio source and it is active. Audio inputs
that are On will automatically be mixed. Unconnected inputs will automatically be muted.
Select Off to prevent audio/noise from connected but unused inputs.
Audio inputs L-R (VCR Left/Right) are intended for connection to a VCR, DVD player or PC
audio output. They can also be connected to other external playback devices. As there is no
acoustic echo canceller on these inputs they should not be connected to any microphones.
The audio entering these inputs will be heard from the local speaker as well.
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 audio equipment that 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.
