In handling the calibration instructions, I am confused about the following;
Input level calibration
I apply a 1kHz, -10dB (0.3V) signal to input 1. Controlled via a parallel connected scope to read on the VU meter 0VU.
The VU meter has a range from - 20 dB to + 3 dB, left to right.
I don't understand now to what reading I should trim input monitor level R107 ?
I start this callibration due to different readings on the 8 channels
