Hello,
i am at the first step of calibrating my compressor using the Hairball audio way.  The problem is that I'm not getting a voltage reading at the output xlr.

I have a signal and reading coming to the input xlr  (.775vac).

I measured the voltage to the input and ground pad on the board and with the input knob at 48 I'm getting 0v and at input 0 I'm getting .875 v. so it seems to be working to here.

I visually checked the wiring from the meter board and input transformer to the output and it is wired fine. 

I'm just not too sure what I should be looking for from here (i.e. what to test and what I should be seeing for readings).

I'm assuming that I shouldn't have the unit plugged in for this step and will not plug it in for testing unless someone recommends that I do so.

Thank in advance for any help.
 
the calibration is done with the meter on the compressor so you don't really need to monitor the output

just set up a 0dB oscillator and follow the steps
