SoundCraft SPIRIT FOLIO User Manual page 4

Accepts XLR-type connectors and is
designed to suit a wide range of
BALANCED or UNBALANCED signals.
Professional dynamic, condenser or
ribbon mics are best because these will
be LOW IMPEDANCE. You can use
low-cost HIGH IMPEDANCE mics, but
the level of background noise will be
higher.
If you turn the PHANTOM POWER on
(top right-hand side of the mixer) the
socket provides a suitable powering
voltage for professional condenser mics.
Unplug any mics if you want to use the
LINE Input. Set the input level using the
GAIN knob.
See page 11
This knob sets how much of the source
signal is sent to the rest of the mixer.
Too high, and the signal will distort as
it overloads the channel.
Too low, and the level of any
background hiss will be more
noticeable and you may not be able to
get enough signal level to the output of
the mixer. See `Initial Setting Up' to
learn how to set the GAIN correctly.

Pressing this switch reduces the level of bass
frequencies only. This feature is very rare for such a
small mixer.
Use this in live PA situations to reduce stage rumble or
`popping' from microphones.
See page 11
Turn to the right to boost low (bass) frequencies, adding warmth to
vocals or extra punch to synths, guitars and drums. Turn to the left to
reduce hum, stage rumble or improve a mushy sound. Set the knob to
the centre-detented position for a neutral EQ response.
Accepts 3-pole `A' gauge (TRS) jacks. Use
this input for sources other than mics, such
as keyboards, drum machines, synths, tape
machines or guitars. The input is
BALANCED for low noise and immunity
from interference, but you can use
UNBALANCED sources by wiring up the
jacks as shown on page 11, although you
should then keep cable lengths as short as
possible. Unplug anything in the MIC input
if you want to use this socket. Set the input
level using the GAIN knob.
