I am actually renewing this nice amplifier.
There are 3 pair of potentiometers to properly set the level meters:
first pair is to set the output to 0dB 10W
second pair -20dB (0,1W)
third pair -40dB (0,01W)
Entrance signal should have following parameters:
150mV -16,5dB 1kHz -36,5dB - 56,5 dB
That damping in decibells is probably achievable in a professional generator.
Is there another, simpler way to set the VU meters ?

Definitely yes - in other amplifiers.
In this amplifier - if you are provided with 3 trimpots per channel then you either use them or do not use them, the choice is yours.
