MIC INPUT
The mic input accepts XLR-type connectors and is designed to suit a wide range of
BALANCED or UNBALANCED low-level signals, whether from delicate vocals requiring
the best low-noise performance or close-miked drum kits needing maximum headroom.
Professional dynamic, condenser or ribbon mics are best because these will be LOW
IMPEDANCE. While you can use low-cost HIGH IMPEDANCE mics, you do not get the
same degree of immunity to interference on the microphone cable and as a result the
level of background noise may be higher. If you turn the PHANTOM POWER on (top
right-hand side of the mixer) the socket provides a suitable powering voltage for
professional condenser mics.

Unplug any mics if you want to use the corresponding LINE Input to avoid the load
presented by the mic from affecting the Line Input gain. The input level is set using the
TRIM knob.
LINE INPUT
Accepts 3-pole `A gauge (TRS) jacks, or 2-pole mono jacks which will automatically
ground the 'cold' input. Use this input for sources other than mics, such as keyboards,
drum machines, synths, tape machines or guitars. The input is BALANCED for low
noise and immunity from interference, but you can use UNBALANCED sources by
wiring up the jacks as shown below, 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. Unplug anything in the MIC input if you
want to use this socket. Set the input level using the TRIM knob.
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 signal from the channel appears on the TIP of the plug and is returned on the
RING.
STEREO INPUTs
Accept 3-pole `A gauge (TRS) 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 below, 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.
FX RETURNS
Similar to the Stereo Inputs, except that they are unbalanced. Input gain is sufficient to
allow the connection of +4dBu professional or -10dBV semi-professional equipment.
