STEREO LIVE SOUND SYSTEM
In a live sound reinforcement or a public address system (P.A.
System), the input signals to the mixer will come from the micro-
phones and instruments on the stage. Each microphone or instru-
ment to be amplified by the P.A. system must be connected to one
of the mixing console inputs. It is preferred to have as many of the
stage instruments as possible plugged into the mixer. This allows
for the best overall sound control of the instruments as they are
mixed together and then amplified by the P.A. system. The mixer
can be operated on the stage or from a remote location in front of
the stage using a snake cable to bring the signals from the stage to
the mixer. The advantage of the remote operation allows the per-
formance to be monitored and mixed from the audience’s perspec-
tive.
THE SOUND CHECK
The sound check takes some skill, but mostly patience from the
performers and especially you the system operator. If you get frus-
trated during the sound check the performers can lose confidence
and the sound may suffer due to things missed in the sound check.
The basic sound check follows this format: First test all micro-
phones and other input devices(direct boxes, etc.) before the per-
formers are included in the sound check. A good thing to also
check here is feedback in the monitors from the microphones.
Good positioning of the monitors and the use of the graphic equal-
izer solves most major monitor feedback problems. Now for a
sound check with the performers. First set the level of each per-
former individually and in cases where a performer has multiple
microphones, such as with a drummer, set each drum mic individ-
ually then the drum set as a whole. This is also a good time to
make some channel tone control adjustments to tailor the sound of
the individual performers and instruments. Next after setting each
individual, have the performers run through a song or a portion of
the show. Don’t hesitate to stop the performers if something needs
to be adjusted or if an individual performer or microphone needs to
be heard solo again. Remember the sound check is not a rehears-
al, but a system check, a time to work the bugs out of the system
so the show can go smoothly. It is always a good idea for the mixer
operator to have a microphone to inform the performers of what is
needed during the sound check. If a monitor system is being used,
the mixer operator’s microphone should only be heard through the
monitors when addressing the on stage performers, especially if
something needs to be checked during the show. If the sound
check is allowed to run through its full course, the system should
run smoothly at show time.

DSP EFFECTS
Select from Reverb, Flange, Chorus, and Echo. Écho delays with reverb includes delay times of 50,100, 150, 250,
350, and 500 milliseconds.
The basic hook up is simple, using four (or
two stereo) RCA cables. Plug the TAPE
SEND on the mixer into the tape deck’s
inputs and the mixer’s TAPE RTN’s into the
tape deck’s outputs. With an external
effects processor, plug a 1/4” cable from
the EFF SEND output on the mixer into the
input jack on the effects processor. Then
from the outputs of the effects processor,
plug one or both (for stereo) cables into the
L/R EFFECTS RETURN.
