Congratulations on your purchase of the Ecoustic
TM
112 This amplifier is primarily designed for acoustic
.
guitars but works equally well with other acoustic instruments, vocals, drum machines, keyboards, or any
other source requiring full-range amplification. The coaxial, 12-inch woofer/soft dome tweeter combination
creates a system with uncompromised lows and very smooth highs. The
5band
active equalization on each
of the two channels, when used with their individual effects loops and on-board spring reverb, allows for
complete control of the tonal balance of the instrument, vocal, etc.
The primary Instrument Channel has a specially designed feedback elimination system that includes a
phase reversal switch, and a frequency sweepable notch system that allows for exact placement on the
problem frequency without reducing the volume in the surrounding frequency band. This system is roughly
equivalent to having a single band from a 31-band,
l/3
octave
EQ
that can be swept from 40 Hz to 2
kHz.
The Microphone Channel includes a phantom-powered balance Low-Z input and a High-Z input that works
simultaneously to allow the use of either type microphone and/or other sources, such as drum machines,
keyboards, tape decks, etc. The equalization is
identic
to that on the Instrument Channel, making this
channel a second guitar input. A commonly used method for amplifying acoustic guitar is to mic the instru-
ment and mix it with the piezo output. By using the phase switch on the Instrument Channel, the user can
easily mix the two with the appropriate phase so as not to cancel any lows.
The inclusion of a transformer-balanced direct output allows the signal to be fed to a mixer either from the
Input of the Instrument Channel or from the preamp out, which contains the sum of the Instrument and Mic
Channels.
FRONT PANEL FEATURES
INPUT (1)
A
l/4”
instrument jack is provided with extremely wide dynamic range. This input will accept very high level
signals or very low signals from any type acoustic instrument.
PASSIVE/ACTIVE SWITCH (2)
Reduces system gain when pressed to allow for greater dynamic range when using instruments with high
output built-in preamps.

BACK PANEL FEATURES
GROUND SWITCH (18)
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-l 20 V products only (19)
A
For your safety, we have incorporated a three-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
properly grounded receptacles.
DIRECT OUT-LOW-Z BALANCED (20)
An XLR jack is provided to route the signal to mixing/recording consoles.
PRE/POST
EQ
SWITCH (21)
Selects either Instrument (Pre EQ) or both the Instrument and Microphone Channel (Post EQ) signals to the
direct out jack.
PREAMP OUT (22)
The Preamp Out can be used to route the amplified signal to a mixing console, tape recorder, etc. Connect
the Preamp output using a shielded cable to the input of “he tape recorder, mixer, etc. This patch does not
affect the operation of the amplifier.

EFFECTS RETURN-INSTRUMENT (27)
Input for returning signals from external low-level effects or signal processing equipment for the Instrument
Channel. (Footswitchable).
REMOTE SWITCH JACK (28)
Provided for the connection of a 2-button, remote footswitch (optional). The footswitch is used to defeat the
effects loop on the Instrument Channel and also allows the user to remotely mute the amplifier.
Note: When the amplifier is muted, the power LED will flash.
IMPORTANT: The mute circuit functions only on the Preamp Out. If the Direct Out is selected to
Instrument (Pre EQ), it will not be muted when the amp is muted.
Note: Effects Loop is footswitchable on the Instrument Channel only.
