Fader Alignment

Changing Input/Output Levels

D/ESAM 820 User's Guide
Use the following procedure to align the Control Panel faders such that electrical
fader position matches physical fader position:
1.
Ensure that monitor levels for all channels are turned down.
2.
Take all faders and physically move them to their uppermost limit (+6
dB position). Leave each fader there.
3.
To align faders, press LOCK/UNLK, hold it down and press FADER
SPLIT. Electrical position now matches the physical scale printed on
the panel. This completes the fader alignment process.
