Mic 1- 3 and Audio input 4-6
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, 2 and 3 are intended for electret type microphones. The microphone inputs are balanced with 24V phantom power.
Audio input 4 is intended for connection to an external microphone amplifier or an external fixed mixer. It is crucial that the external mixer is a fixed mixer. Automatic, smart and other types of adaptive mixers might cause the echo canceller to malfunction.
Audio input 5 is intended for connection to external playback devices or to telephone
Audio input 6 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 6. If input 5 and 6 is configured to one stereo input pair, see Stereo Settings, then the VCR ducking will apply to both input 5 and 6.
