4.5.1 Inputs
Mic 1- 2 and Audio input 3-4
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. The activated audio sources are stored
on camera presets.
Mic 1 and 2 are intended for electret type microphones. The microphone inputs are balanced with
24V phantom power.
Audio input 3 (AUX) is intended for connection to external playback devices, but the input can
also be configured as a microphone input by selecting Mic. When set as a microphone input it will
turn off and replace the Mic 2 input. The audio will be mixed an set up as for the Mic 2 input and
there will be an echo canceller working on the input to prevent unwanted echo to be heard at the
far end. When not configured as a microphone and connecting an external playback device to this
input there will be no echo cancelling and the audio source connected to Audio input 3 will be
heard from the local loudspeaker as well.
Audio input 4 (VCR) is intended for connection to a VCR or DVD player. It can also be connected
to other external playback devices. As there is no acoustic echo canceller on this input it should
not be connected to any microphones. The audio entering this input will be heard from the 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.
The VCR ducking is only valid for audio input 4. If input 3 and 4 is configured to one stereo input
pair, see Stereo Settings, then the VCR ducking will apply to both input 3 and 4.
