SoundCraft Spirit Folio 4 - Manual (Page 4)

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 (shown by illumination of the PEAK LED),
and causes clipping. 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.
Setting the knob to the `U' mark gives unity gain for the LINE input.
These sends are always PRE-FADE,
PRE EQ and are unaffected by the ON
switch. They would typically be used
for Foldback or Monitor feeds, for
which it is important that the send
should be independent of the fader so
that, for instance, the mix to artists
headphones or monitor wedge is not
affected by changes in fader level.
This control sets the
amount of the channel
signal feeding the Right
and Left MIX or GROUP
outputs, allowing you to
move the source
smoothly across the
stereo image. Rotation
fully anticlockwise feeds
the signal solely to the
Left mix bus, Group 1 or
Group 3, while rotation
clockwise sweeps the
image to the right bus,
Group 2 or Group 4.
Pressing this switch reduces the level of
bass frequencies only, and is a real bonus
on a compact mixer.
Use this in live PA situations to reduce stage
rumble or `popping' from microphones.
There are two knobs which work together to form a SWEPT
MID EQ. The lower knob provides 15dB of boost and cut,
just like the HF EQ knob, but the frequency at which this
occurs can be set by the upper knob over a range of 250Hz
to 6kHz. This allows some truly creative improvement of the
signal in live situations, because this mid band covers the
range of most vocals. Set the lower knob to the
centre-detented position when not required.
Turn to the right to boost high
(treble) frequencies by up to
15dB, adding crispness to
cymbals, vocals and electronic
instruments. Turn to the left to
cut these frequencies by up to
15dB, reducing hiss or
over-emphasis of
high-frequency consonants,
which can occur with certain
types of microphone. Set the
knob in the centre-detented
position when a flat response
is required.
Turn to the right to boost low
(bass) frequencies by up to
15dB, adding warmth to vocals
or extra punch to synths,
guitars and drums. Turn to the
left to cut low frequencies by
up to 15dB for reducing hum,
stage rumble or to improve a
mushy sound. Set the knob to
the centre-detented position
when not required.
