11.3 Audio Parameter Configuration
To Configure the Music Input Audio Parameters:
4. Select the music input, and then modify the required audio parameters as follows.
Note that the in addition to the unbalanced input (Input 9), a balanced input can be used for background
music.
5. Define a gain to be applied to the input audio, in respect of any output to which it may be routed.
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆI/P #<nn>ÆAudioÆGainÆInputs
L
The input gain of each audio input should normally be set so that all inputs are balanced,
and give the same output level on each of the outputs.
6. Define the output specific relative gains.
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆI/P #<nn>ÆAudioÆGainÆOutputs
L
• Normally all Music input gains will be set to ‘balance’ the input, and the output gain will
be set to give the required level at each output. However, if the Music input is desired
to have a different gain in a particular output or outputs, then these inputs can be given
a different gain relative to each appropriate output.
• Any output level adjustment should be performed with the ANS function for that output
disabled, as described in Section ”18.2 Output Configuration for ANS Monitoring”.
7. Define the relative gain for each frequency band (low, mid, and high frequencies) of 3-band equaliser.
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆI/P #<nn>ÆAudioÆEQ
If using a balanced input for background music, make sure that the switchable High Pass filter is
disabled.
