Audio Processing
You may, for example, pan the signals, route them to buses and set the
desired volumes.
Note Mic inputs are only available if you set the appropriate Audio Mode in the
AUDIO submenu of the SETUP main menu (see Audio Submenu on
page 129).
5.4.2 Stereo Inputs
You can use up to eight stereo audio inputs simultaneously, for example,
audio signals from video channels and separate signals from CD players
or other devices.
The stereo inputs can be processed the same way as the microphone
inputs.
5.4.3 Adjusting Audio
The audio channel settings can be edited in the AUDIO MIXER main menu
(see Audio Mixer Main Menu on page 97) and via the audio faders and
buttons on the front panel.
Some important functions are explained here.
Equalizer
An equalizer allows you to manipulate the frequency spectrum of an audio
signal. You can use it, for example, to prevent feedback in live situations,
to reduce unwanted frequencies like low-level noise, or to raise frequen-
cies that are important for an instrument’s sound or a speaker’s intelligi-
bility.
The INDIGO AV Mixer provides a 4-band equalizer for each channel, i.e.
you can adjust four different frequencies simultaneously: Low, Mid 1,
Mid 2
, and High.
Additionally, there is a Low Cut for each channel that cuts all frequencies
below 100 Hz to reduce low-level noise.
ON Button
This button toggles between on and off.
If, for example, one of two microphones is not used for a while and has to
be activated later at the same level, you will not need to adjust the fader to
reduce the level. Simply press the
ON button (in the AUDIO MIXER main menu
or on the front panel). This turns off the related audio channel. To turn the
channel on, press the
ON button again.
