To prevent damage to the input mixer, the power level at the input mixer

C A U T I O Nmust not exceed +72 dBmV. To prevent signal compression, power at the input to the input mixer must be kept below 39 dBmV.

N O T E

To protect the mixer from possible damage, 0 dB RF attenuation (no input power reduction to the mixer) can be selected only from the number/units keypad.
