help me understand input voltage

The CDA9887 has a pre out rated at 4volts. O.K.

the EQ215i says to adjust the input untill the light flicks 1 time a sec. This is approaching 8 volts. O.K.

I get this. But then

It says to adjust the output according to the amplifier specification. The XS4600 says input sensetivity is 1-3 volts :? Unless i am reading this incorrect. I am supposed to kill off the 8 volt clean unclipped signal down to 3 volts ??? That means the output signal knobs will be so low they wont even register into the green LED display on top of the EQ.

Am I understanding this correctly. The signal should only be 3 volts going to the amp and then i want to adjust the sensativity on the amp to bring the levels back up to where I want them.


Help

Not much point in boosting the input voltage only to cut it. I'd basically roll with EQ gains at 0... maybe to bump your signal to 4v rms (which you can measure with an AC voltmeter and a 60Hz tone, just like the amp outputs).
