GETTING TO KNOW YOUR CONSOLE
MONO INPUT CHANNEL
1 & 2 MICROPHONE/LINE INPUT
The MICROPHONE input (1) is via a standard female XLR-3
connector and shares an input stage with the Line input. It is
designed to accept a wide range of balanced or unbalanced
low impedance input signals. The LINE (2) input is a 3-pole
1
⁄
4
" ‘A’ gauge jack socket and presents a high impedance
(>10k
Ω
) to the input signal, enabling many types of
instruments to be plugged straight in without D.I. boxes or
external preamplifiers. Any connection to the Mic input
should be unplugged when the Line input is in use
.
+48V Phantom Power is available on each input microphone
socket. This is switched on globally from the master section at
the top right corner of the mixer. All faders should be
DOWN when switching on phantom power.
NOTE: Phantom powered mics should not be plugged in
with the +48V switched on. DO NOT use phantom power
with unbalanced mics or damage may result.
Transformer-coupled dynamic microphones may be used
without causing damage, even when the +48V power is
connected.
Input level is set by the GAIN control (4).
3 INSERT
The INSERT is a break point in the input channel signal path.
It allows the signal to be taken out of the mixer, through an
external piece of equipment such as a compressor and then
back into the mixer to continue through to the final mix
output. The Insert is a 3-pole
1

" ‘A’ gauge Jack Socket, which
is normally by-passed. When a jack plug is inserted, the
signal path is broken at a point just after the Hi-Pass Filter,
but before the EQ section. The signal from the channel
appears on the TIP of the plug and is returned on the RING.
The insert point allows limiters, compressors and other signal
processing units to be added as required to particular input
channels and because it is located PRE EQ, noise generated by
the external equipment may be reduced by a small amount of
H.F. cut in the Equaliser.
