Adjusting Digital Input Gain
If your system has digital input gain control, adjustments (within the gain range
for the specific audio input board) can be made at any time during normal
operation. When audio is adjusted for a device on one virtual matrix, the
adjustment remains in effect for that device on all virtual matrices switching
audio signals.
Caution: We strongly recommend that digital input gain adjustments be made
only by a qualified dealer.
The purpose of controlling input gain (the nominal level of the signal from the
source device) is to allow source signals of various amplitudes to be equalized
before they are routed and the volume is adjusted. Equalizing source levels
provides a consistent reference for volume adjustments and eliminates jumps
when routing a new source to a destination.
Typical uses for input gain include switching consumer and professional grade
audio equipment (whose levels can vary noticeably) in the same matrix switcher.
Input gain adjustment is also used for equalizing amplitudes between balanced
and unbalanced source inputs.
The example below adjusts the input gain for Input (source)
26: Main Mic Mtg Rm A on Virtual Matrix 2.
To adjust input gain to equalize input levels:
1. At the Main Menu screen, choose the Audio command.
If the Audio command is not available, press the Function key to view
