9.1.3 Music Input Gain Configuration
Each of Music inputs (Music A and Music B) has adjustable analogue gain analogue. The analogue gain
settings are non-volatile, are and retained even after power failure and/or processor failure.
In order to set the input gain and the line sensitivity proceed as follows.
1. Select ConfigurationÆSystemÆRouterÆInputsÆMusic/MuteÆMusic A or Music B.
From V4.1.0470 or later:
ConfigurationÆSystemÆRouterÆInputsÆMiscÆMusicÆMusic A or Music B
2. Move to, and select the Gain menu item:
[Gain] EQ Name
3. Scroll the input gain values until the required value is displayed:
[Gain(dB)=-25]
Default value: ‘–25’
Possible values: –63dB to 0dB (1dB steps)
Note: 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.
Note that this adjustment works in real time, so it can be experienced immediately on any live
routes.
4. Save the changes by pressing the SELECT key, or cancel by pressing the BACK key.
