Hello friends, I hope you are doing well. I'm new here, but I can see this is a great community.
A couple of years ago, I bought 2 FC526-XFMR for my dad to assemble. He did so, but before calibrating them, he passed away due to COVID-19. I don't want to talk about the sadness of this... I was left with two uncalibrated compressors, as I don't know much about electronics. I'm a musician, I've been studying a lot and have already achieved some things, but there are two issues I can't resolve. I know they're silly for those who know, and I apologize, but I can't find this information anywhere...
In the review sheet, in the "Gain Reduction Meter Calibration" section, point 4 says "Turn the input pot up to approximately 1:00". So, What is 1:00? Let's say if I put the potentiometer fully CCW and move it CW to the first painted dot, is that what it refers to as 1:00? If I do this and move the GR Switch, I don't have any gain reduction. But if I put the potentiometer, let's say, past the middle of the potentiometer, where on a wrist clock it would be 1:00 PM, I do have gain reduction when activating the switch. I'm adding a photo where I left the input and output potentiometers where I more or less get the desired reduction (-7dB). Could you tell me if this is correct?
Also, in the "Pre Calibration Information" section, point 2 says "2. Before proceeding forward with the meter calibration steps below, make sure you have between +2.498V DC and +2.502V DC at the "top" of the meter resistor string for the LM339 comparators, which is MTR point #11 in the pic. See the Test Points Guide for more info."
To check #11, do I put the multimeter on one side to ground (as when checking test points) and the other on #11 as in the second photo I added? This way, I'm getting 2.46 volts. Is this okay, or is something wrong?
I greatly appreciate your time. This was long; I wanted to be as clear as possible. Greetings and have a good weekend!
