FRONT PANEL
HIGH GAIN INPUT (1)
Used for most electric guitars. It is 6 dB louder than the Low Gain input.
LOW GAIN INPUT (2)
Provided for instruments that have extremely high outputs, which can result in overdriving (distorting) the High Gain input. If
both inputs are used simultaneously, the output levels are the same (both are Low Gain).
BRIGHT SWITCH (3)
Provides a preset boost (+ 8 dB) to treble frequencies. To activate, depress the switch to its “in” position.
PRE GAIN (4)
Controls the input volume level of the amplifier.
POST GAIN (5)
Controls the overall volume level of the amplifier. The final level adjustment should be made after the desired sound has been
achieved.
LOW (6)
An active tone control (shelving type, +/- 15 dB) that varies the low frequency boost or cut.
OPERATION NOTE
Excessive EQ boost, especially of the low frequencies, increases the possibility of speaker damage, and sacrifices valuable
heacroom.
GRAPHIC EQUALIZER (7)
This seven-band, one octave equalizer provides 15 dB of boost or cut at each center frequency.
HIGH (8)
An active tone control (shelving type +/- 15 dB) that varies the high frequency boost or cut.
CHORUS EFFECTS SEND (9)
High pass output above 200 Hz for supplying signals to external effects or signal processing equipment.
EFFECTS RETURN (10)
Provided for patching an effects device output back into the mixer, May also be used as an independently variable auxiliary
input.
PREAMP OUT/POWER IN (11)
These jacks are provided for in-line patching of effects devices. To patch an effects unit, connect the Preamp Qutput to the
Input of the device. Next, connect the output of the device to the Power Amp Input (high-quality shielded cables must be used
for these connections). The Preamp Output can also be used to route the amplified signal to a mixing console, tape recorder,
etc. Connectthe Preamp Output, using a shielded cable, to an input of the tape recorder, mixer, etc. This patch does not affect
the operation of the amplifier. NOTE: The preamp output level is approximately 1 volt RMS and is of relatively low impedance
(600 ohms). Any effects device used in this effects loop must be capable of receiving 1 volt input and providing 1 volt output
in order to properly drive the power amp. The Power Amp Input has an internal switch which disconnects the internal preamp.
HEADPHONE JACK (12)
This stereo jack allows signals to flow to both sides of any stereo headset.
POWER LED (13)
Iluminates when AC power is being supplied to the amp.
POWER SWITCH (14)
Depress to “Cn” position to turn on.

LINE (MAINS) CORD RETAINER (15)
Allows storage of mains cable for travel.
GROUND SWITCH (16)
Three position rocker-type switch which, in most applications, should be operated in its center or zero position. There may be
some situations when audible hum and/or noise will come from the loudspeaker. If this situation arises, position the ground
switch to either positive or negative (+ or -) or until the noise is minimized.
NOTE: Should the noise problem continue, consult your Authorized Peavey Dealer, the Peavey Factory, or a qualified service
technician. THE GROUND SWITCH IS NOT FUNCTIONAL ON 220/240 VOLT MODELS.
LINE CORD (120 V PRODUCTS ONLY) (17)
For your safety, we have incorporated a 3-wire line (mains) cable with proper grounding facilities. It is not advisable to remove
the ground pin under any circumstances. If it is necessary to use the equipment without proper grounding facilities, suitable
grounding adaptors should be used. Less noise and greatly reduced shock hazard exists when the unit is operated with the
proper grounded receptacles.
