:  Input level will vary, the important level to worry about is the output level because that level can be control with input plugin attenuators.  Need to know the gain of the amplifier before you can select the plugin attenuator.  For example if the gain of the amplifier is 40dB and you are trying to achieve a output level of 50 dbmv, therefore the input level has to be at least 10 dbmv, levels are referenced to the highest frequency of the signals in the bandwidth.  If the input level is above 10 dbmv, we can use the correct value plugin attenuator to achieve the desire 50 dbmv output level.
