A ‘Y’ lead may be required to connect to equipment with separate send and
return jacks as shown below:
Stereo Inputs STEREO 1/2
These accept 3-pole 6.35mm (1/4") 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, al-
though 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 Outputs
The MIX outputs are on XLR’s, wired as shown, and incorporate impedance
balancing, allowing long cable runs to balanced amplifiers and other equip-
ment.
Aux and FX Bus Outputs
The Aux and FX Bus outputs are on 3-pole 6.35mm (1/4") jack sockets, wired
as shown on the left, and are balanced, allowing long cable runs to balanced
amplifiers and other equipment.
Headphones
The PHONES output is a 3-pole 6.35mm (1/4") jack, wired as a stereo output
as shown, ideally for headphones of 150
Ω or greater. 8Ω headphones are
not recommended.
