Stereo Inputs STEREO 1/2
These accept 3-pole ‘A’ gauge jacks, or 2-pole mono jacks which will automatically
ground the ‘cold’ input. Use these inputs for sources such as keyboards, drum
machines, synths, tape machines or as returns from processing units. The input is
BALANCED for low noise and immunity from interference, but you can use
UNBALANCED sources by wiring up the jacks as shown, although you should then
keep cable lengths as short as possible to minimise interference pick-up on the
cable. Note that the ring must be grounded if the source is unbalanced.
Mono sources can be fed to both paths by plugging into the Left jack only.
Mix Inserts
The unbalanced, pre-fade Mix insert point is a break in the output signal path to
allow the connection of, for example, a compressor/limiter or graphic equaliser.
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 mix fader.
The mix signal appears on the TIP of the plug and is returned on the RING. A ‘Y’ lead
may be required to connect to equipment with separate send and return jacks as
shown below:
Mix Outputs
The MIX outputs are on XLR’s, wired as shown, and incorporate impedance balanc-
ing, allowing long cable runs to balanced amplifiers and other equipment.
