There was a time when the P.A. system and the operator
existed only to increase the overall volume of the performers,
so that they could be heard in a large room or above high
ambient noise levels. This just isn’t true any more. The sound
system and the sound engineer have become an integral part
of the performance, and the artists are heavily dependent on
the operator’s skill and the quality of the equipment.
The following introduction to the basics of mixing are
included for the benefit of those users who may not have any
significant familiarity with sound equipment, and who are
baffled by the endless jargon used by engineers and artists
alike.
The four Output Groups provide submixing to the Mix L/ R
outputs or may feed external equipment directly. Each
incorporates stereo panning and PFL monitoring or bargraph
metering and includes an external Return input for effects or
submixing from external sources.
The Master section provides master level control for the Left,
Right, Mono and Auxiliary Send busses, with separate AFL
monitoring on each Auxiliary Send and the Mono output.
The Mix L/ R and Group outputs all have insert points for the
connection of external signal processing.
Comprehensive Talkback facilities are provided, which allow
an external talkback microphone to be routed to Mix L/ R,
Groups and Auxes 1 & 2 as required. Six 12-segment, 3-colour
peak reading LED bargraph meters provide clear display of
Mix L/ R, Group and PFL signals. Pressing any PFL or AFL
switch puts the selected signal onto both sides of the
headphones output, and the right bargraph meter.
SPIRIT Live 4 is designed to be as user-friendly as possible,
but a few minutes spent reading through this manual will
help you become familiar with the product away from the
pressure of a live session, and allow you to gain full benefit
from the superb performance offered by your new mixer.
Above all, remember that your SPIRIT mixer is designed to
extend your creativity. The more you explore the controls
and the effect they have on the sound output, the more you
will appreciate how you can influence and enhance the final
sound.
