INSTALLATION Configure the matrix mixer input from the codec output. The input gain of the matrix mixer should be set to match the nominal output level of the codec. For example, if the codec outputs a -10 dBV (-8 dBu) level, 8 dB of gain should be applied on the matrix mixer input. This will bring the codec level up to 0 dBu inside the matrix. Verify Room Gain After adjusting the loudspeaker level, verify the room gain in your system using the ROOM GAIN meter on the DIAGNOSTICS page of C
