GETTING TO KNOW YOUR CONSOLE
FACILITIES
Refer to the fold-out front panel diagram at the rear of this
manual, which shows the control functions on the SPIRIT
Monitor. Each facility is described below, and is identified by
a reference number.
INPUT CHANNEL
1. MICROPHO NE INPUT
The Microphone input is via a standard female XLR-3 connec-
tor and is available when the LINE switch is released. It is
designed to accept a wide range of balanced or unbalanced
low impedance input signals.
+48V Phantom Power is available on each input microphone
socket, with an overall ON/OFF switch at the right hand side
of the console, beside the power input socket.
Transformer-coupled dynamic microphones may be used
without causing damage, even when the +48V power is con-
nected, but care must be taken when using unbalanced
sources, because of the voltage present on pins 2 and 3 of the
XLR connector.
NOTE: The microphone should always be plugged in before
switching the +48V on or off. Also you should be aware that
some microphones draw an unusually large current which
may overload the power supply, resulting in distortion. Con-
sult your microphone supplier for guidance if necessary.
2. 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 and then back into the mixer to
continue through to the final output. The Insert is a 3-pole

‘A’ gauge Jack, 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
