6 - INSERT POINT

The unbalanced, pre-EQ insert point is a break in the channel signal path, allowing

limiters, compressors, special EQ or other signal processing units to be added in the

signal path. The Insert is a 3-pole ‘A’ gauge jack socket which is normally bypassed.

When a jack is inserted, the signal path is broken, just before the EQ section. The Send

may be tapped off as an alternative pre-fade, pre-EQ direct output if required, using a

lead with tip and ring shorted together so that the signal path is not interrupted.

CT OUTPUT

Channels 1-8/1-16/1-24 (see block diagram) have a dedicated Direct Output which

allows direct connection to external devices, for example to feed Tape Machines or

effects units.

The pre-fade direct output level may be monitored by pressing the PFL switch on the

appropriate channel to feed the pre-fade signal to the monitors and the bargraph

meters.

The Direct Outputs are normally set POST-FADER for use as effects sends or to provide

fader control of recording levels in a studio recording application. For live recording the

outputs can be individually changed to PRE-FADER by pressing this switch, so that the

direct output level remains unaffected by fader settings for the main PA mix.

ALISERALISER

ALISER

The Equaliser (EQ) allows fine manipulation of the frequency bands, and is particularly

useful for improving the sound in live PA applications where the original signal is often

far from ideal and where slight boosting or cutting of particular voice frequencies can

really make a difference to clarity.

AINAIN

AIN

This knob sets how much of the source signal is sent to the rest of the mixer. Too high,

and the signal will distort as it overloads the channel. Too low, and the level of any

background hiss will be more noticeable and you may not be able to get enough signal

level to the output of the mixer.

See `Setting Up & Troubleshooting’ on page 20 to learn how to set GAIN correctly.

Pressing this switch activates a steep 18dB per octave filter which reduces the level of

bass frequencies only. Use this in live PA situations to clean up the mix, reducing stage

rumble or ‘popping’ from microphones.
