OPERATION
In normal use the power amplifier can be left switched on at the back panel.
The signal sense circuitry automatically switches the power amplifier to
standby after a few minutes if no input signal is present, and the front panel
indicator changes from green to red.
The sensitivity adjustment control on the back panel allows you to adjust the
signal sensing threshold. Normally this should be at maximum sensitivity.
Only back this off if the amplifiers regularly get powered up by interference
or noises in the system.
Should you wish to bypass the signal sense circuit an internal link can be
fitted which forces the amplifier to power up as long as mains power is
applied. Please consult your retailer if you wish this to be done.
