10
MASTER Control
This is the overall Master volume control to adjust your room sound level.
5
GAIN Control
Controls the preamplifier drive level.
Low settings give cleaner sounds, higher give more distortion.
This should be used in conjunction with the VOLUME control to give sensible levels.
(Rule of thumb Low GAIN settings use high VOLUME settings. High GAIN settings use lower VOLUME settings)
This will give good overall balance to all your sounds.

(Setting too high on overdriven sounds can cause unwanted distortion)
7
BASS Control
