c. Ensure that all Volume Controls are set to maximum volume, i.e., control at position '11'.
d. Make broadcasts from the fist microphone and confirm that they are free of acoustic feedback.
e. If feedback is encountered or volume adjustment is required in a particular zone (or one or more of the
group of zones) even though all inputs have been balanced, and all outputs have been set to the
correct volume for all other inputs, then reduce the Relative Output Gain for the associated output until
the feedback is eliminated.

Microphone Equalisation

Menu: Configuration or Config System Router Inputs Mic/Line
Possible values:
System default configuration:
A 3-band equaliser is provided on Mic/Line inputs in order to balance the input tone. This equaliser has a
shelving HF (treble) adjustment, shelving LF (bass) adjustment, and a fixed MID section adjustment.
A High Pass filter is also configurable. This would typically be used on microphone inputs to prevent
excessive 'pop' noise.
Set the equaliser as required.

Microphone Fade Up and Down Times

Menu: Configuration or Config System Router Inputs Mic/Line <I/P #nn – input name>
Possible values:
System default configuration:
The Fade Down time is:
•
The time it takes for the signal to fade down when turned off (un-routed);
•
The time it takes for the signal to fade down before an overriding broadcast is made in its place
