Refer to the fold-out front panel diagram at the rear of this
manual, which shows the control functions on the SPIRIT
STUDIO. Each facility is described below, and is identified

INPUT - CHANNEL PATH
1. MICROPHONE INPUT
The Microphone input is via a standard female XLR-3
connector and is available when the LINE switch is re-
leased. It is designed to accept a wide range of
balanced or unbalanced low impedance input signals.
2. +48V PHANTOM POWER
Each microphone input can provide the +48V neces-
sary for phantom-powered mics and this may be
turned on or off with the +48V switch.
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, re-
sulting in distortion. Consult your microphone supplier
for guidance if necessary.
Transformer-coupled dynamic microphones may be
used without causing damage, even when the +48V
power is connected, but care must be taken when us-
ing unbalanced sources, because of the voltage
present on pins 2 and 3 of the XLR connector.
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 and then back
into the mixer to continue through to the final output.
The Insert is a 3-pole 1 ⁄
