restrict the full undistorted output of the amplifiers. Note that the actual output power available often depends on the mains supply voltage, which may ‘sag’ during heavy performances.

In a system where the amplifiers are capable of exceeding the ratings of the speakers, set the threshold to a level appropriate to the speakers and NOT the clipping point of the amplifier. This is normally achieved by feeding the system with pink noise at the maximum level required and then turning down each limiter threshold switch until the yellow LIM LED is just flashing.

Limiter Cancel

When up (CANCEL), this switch will disable all limiters and the yellow LIMITER CANCEL LED will light. It is normally only used when setting up and calibrating - or trouble shooting - the system.

When the limiters are cancelled the output meters will continue to operate normally up to the limiter threshold.

Output Level and Limiter Meter

The lower four green LEDs show the signal level in dB relative to the limiter threshold. i.e. they always show the signal headroom that is available before the limiters will start operating. The yellow LIM LED lights when the threshold has been reached and the limiter is operating. The top red LED lights when the input signal is causing 4dB or more limiting to occur. If during use the +4 LEDS are on for more than occasional brief flashes the input signal is too hot and should be turned down at the mixing console to reduce distortion.

Band Mutes

Each output has an independent MUTE Switch and red MUTE LED. These are latching switches which will retain their settings even when power is turned off and on again.

Note that the MUTE LED will always follow the position of the MUTE switch regardless of the status of the standby mute. If the expected output signal appears to be muted but the MUTE LED is not lit then check the STANDBY MUTE LED
