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.

FAC ILITI ES

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.
