Peavey PA 700S - Page 7

The REVERB CONTOUR (16) is the control used to vary the tonality of the reverb signal and is a low
cut type equalizer. This contour control is very useful in tailoring the reverb sound and in controlling reverb
induced feedback. Balancing these reverb controls will yield many combinations of reverb delay, tonality,
and sustain.
The REVERB RETURN (22) is the gain control element for the reverb system which normally con-
sists of the internal delay line unless the switching jack for the reverb return has been plugged into. We have
designed a system that provides an automatic patching facility for the internal reverb with the added flexi-
bility of being able to accept signals from outside sources. This is accomplished by use of a switching jack
on the rear panel (reverb return). If it should be necessary to use the reverb mixing buss for other purposes,
we have designed in the flexibility to allow this option.
The REVERB PAN (23) is the control that enables the operator to place the signal from the effects
level control on either, both, or any combination in between the left and right main channels. This panning
capability must be present to retain true stereo stereo capability for the PA 700S. The action of this pan
control is similar to those on the individual channels and should present no problem in operation.
The MONITOR MASTER FADER (10) is the output level control for the main monitor system. The
same operating practices should be observed when using this control as when using the main channel con-
trols. The individual channel monitor send controls should be set in such a manner that will allow the moni-
tor master slider (fader) to be operated somewhere in the middle of its travel to allow yourself adequate
control margins, up or down, as might be required on the job. The monitor output signal is flat, that is,
we did not include equalization for the monitor in the PA 700S since this equalization is usually external
to the mixer and is best performed on the stage itself, which is generally at some considerable distance
from the mixer. It is because the mixer is usually located remotely from the performing area that it is
sometimes difficult for the monitor equalization to be performed at the mixer.
The METER SET CONTROLS (17) (18) enables the VU METERS (19) (20) to be adjusted for proper
indication of the relative output power of the internal power amplifiers of the PA 700S. When the PA 700S
is received, the meters will be properly calibrated to indicate the clipping point of the power amplifiers.
Occasional deflection into the red zone is normal, but continual pegging of the needles is to be avoided.
The HEADPHONE LEVEL CONTROL (21) adjusts the signal level at the headphone output jack.
The headphone jack is a standard stereo type jack. Any impedance headphones may be used with the
PA 7008.
REAR PANE!
The PA 700S rear panel features a complete patching panel for various input and output functions,
as well as the microphone input connectors for each channel.
Each patch point is given an alphatical diagram letter for identification purposes. The high impedance
input connectors are standard phone jacks. The low impedance input connectors are of the cannon type,
three conductor connectors to be used for low impedance microphones only, and will accept 150 to 600
ohm microphones.
CAUTION
NEVER USE THE LOW IMPEDANCE AND HIGH IMPEDANCE INPUTS SIMULTANEOUSLY!
The PA 700S is a stereo mixer with self-contained power amplifiers, therefore, many of the input and
output patch points perform the same functions. For this reason only one set of connectors will be ex-
plained in detail.
The POWER AMP IN (A) jack allows a signal to be connected directly to the internal power ampli-
fier. When a plug is inserted in this jack, none of the front panel level controls will be functional. All
mixer functions are disconnected when this jack is in use.
The GRAPHIC IN (B) jack enables a signal to be injected directly into the graphic equalizer and
through to the power amplifier associated with that equalizer. All mixer functions are disabled when this
jack is in use.
The GRAPHIC OUT (C) jack allows the user to have access to the channel output signal after the
graphic equalizer and prior to the power amplifier. It is possible to mix an additional input at this point if
the signal to be mixed is froth a low impedance source and has a level of approximately 1.0 Volt r.m.s.
