4.5.1 Inputs
Mic 1- 3 and Audio input 4-6
By default, all inputs are enabled. Just plug in an audio sou rce 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 conne ction 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 m alfunction.
Audio input 5 is intended for conne ction to external playback device s or to teleph one add-on
hybrids. As there is no acoustic echo canceller on this input it should not be connected to any
microphones. The audio source connected to this input will be heard from the local speake r as
well.
Audio input 6 is intended for conne ction to a VCR or DVD player. It can also be connected to
other external playback devices. As there is no acoustic echo can celler on this input it should not
be connected to any microphon es. The audio entering this input will be heard from the local
speaker as well. If Auto is selected, the audio from the VCR will on l y 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 ba ckground noise.
Fixed
Fixed will maintain a constant weig hting 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 config ured to one stereo input
pair, see Stereo Settings, then the VCR ducking will apply to both input 5 and 6.
