SoundCraft SPIRIT POWERSTATION, User Manual

Page: 6 / 37

The
SPIRIT POWERSTATION
forms the heart of a complete
sound system, and splits into five sections. The Inputs
receive, match and process individual source signals, and
distribute them at precise mix levels to a stereo Mix output.
The Master section allows overall level control of the outputs,
and provides monitoring of the audio signal at many points in
the mixer, either on headphones or meters. The Graphic
Equaliser
provides a means of correcting the output signal to
suit different room acoustics, and the Lexicon Digital Effects
Processor
offers a wide range of treatments to the sound. The
Power Amplifier receives the output from the other sections
and drives the loudspeaker system. A brief overview of the
facilities is given below:
The Auxiliary Sends provide a way of routing the input
signals to a choice of secondary outputs, for artists foldback,
echo units or additional speaker outputs. The Aux 2 control
also provides access to a dedicated feed to the Lexicon Digital
Effects Processor.
The Pan control adjusts the position of the input signal within
the stereo mix, and can be swept from full left, through to full
right. This allows particular artists to retain their correct
spatial position within the mix, and can be valuable for live
effects.
Pre-Fade-Listen(PFL) allows you to monitor the signal at
many points in the mixer. Pressing any PFL switch places the
signal at that particular point onto the headphones and the
meters (if PFL is selected as the Monitor Source), to check the
quality of the signal or to pin-point problems. Using PFL will
not affect the signals on the outputs from the desk.
Each input channel and the main L/R outputs have an Insert
‘A’ gauge jack socket, which is a break point in the 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
directly after its original exit point. The Insert point is
normally bypassed by the ‘A’ gauge jack socket contacts, and
is only brought into operation when a plug is inserted.
Typical uses would include Effects Processors, Limiters,
additional Equalisers or Delay units.
The terms PRE and POST are often used in the context of
Inserts, Equalisers and Auxiliary Sends, and describe whether
that facility is placed before (Pre) or after (Post) another
particular section. This is explained further in the detailed
description of facilities.
