GETTING TO KNOW YOUR CONSOLE
Refer to the fold-out front panel diagram which shows the
control functions on the SPIRIT LIVE 4. Each facility is
described below, and is identified by the reference number.

INPUT CHANNEL
1. MICROPHONE INPUT
The Microphone input is via a standard female XLR-3
connector and is available when the LINE -20dB 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. This is switched on globally from the power supply in
the case of the 12, 16 and 24 channel desks, or from a rocker
switch adjacent to the d.c. power connector at the top right of
the 32 channel desk. Should you wish to configure inputs
without +48V power, see Selectable Options on Page 27 for
details of this modification.
Transformer-coupled dynamic microphones may be used
without causing damage, even when the +48V power is
connected, but care must be taken when using unbalanced
sources, because of the voltage present on pins 2 and 3 of the
XLR connector. Microphone input level is set by the GAIN
control(6).
NOTE: Phantom powered mics should not be plugged in
with the +48V switched on. Also you should be aware that
some microphones draw an unusually large current which
may overload the power supply, resulting in distortion.
Consult your microphone supplier for guidance if necessary.
2. DIRECT OUTPUT
A ground compensated DIRECT output is provided, fed from
the output of the fader buffer, which is therefore unaffected
by the position of the ROUTING switches or PAN control.
This provides an ideal source for external processing units,
the output of which may be brought back to the console
through the STEREO sections or group RETURNS, or to
directly send to the tracks of a tape machine for multitrack
recording. This provides as many Tape Sends as there are
mixer channels, without using the group or mix outputs.
