Changing the Gain of Your Amplifier: Internal Adjustments!

These instructions are for use by qualified personnel only. Before any routine maintenance,
please ensure that your amplifier is disconnected from the mains supply!
Gain/Sensitivity Settings
Adjustment is by moving a link on the input PCB (PCB741) — one link for each channel.
Channel A's link is number 1, channel B's is number 2 and so on.
The gain may be set to 26, 32 (factory default setting) or 36dB.
Remember, setting higher gain does not change the maximum available power but changes
the level of signal input to achieve maximum power. In any case, provided that the input
signal is less than 20dBu/7.7V, the built in limiter circuit will prevent distortion within the
amplifier.
The gain should be set to match the signal level from the source — mixer, equaliser etc.
