GAIN
Facility for switching between high (H) and
low (L) gain. The appropriate LED illumi-
nates to show which position is active.
H (HIGH) position:
This is the standard position for the majority
of power amplifiers and loudspeakers.
L (LOW) position:
A lower gain setting is recommended only
when high efficiency speakers such as
horns are being used.
When switching between gain settings, the
muting function is activated to prevent
switching noises being sent to your ampli-
fier and loudspeakers. The outputs are
restored after a short time. (The muting
LED turns off.) The gain and phase
switches should not be operated at the
same time or immediately after each other,
as this could cause cracking noises through
your system.
