Congratulations on your purchase of the Ecoustic™ 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 5-band 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, 1/3 octave EQ that can be swept from 40Hz to 2kHz .

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 identical 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 instrument 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 1/4'' 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.

PHASE REVERSE SWITCH (3)

Reverses the phase of the instrument signal in order to reduce feedback or to correct out-of-phase conditions when using both the Instrument Input and Mic Input on a single instrument.

INSTRUMENT LEVEL (4)

Control is the overall volume level of the Instrument Channel.

EQUALIZATION—INSTRUMENT CHANNEL (5)

Specially designed 5-band, active equalization.

FREQUENCY (6)

Provides selectable frequency shift of notch filter from 40Hz to 2kHz to eliminate acoustical instrument feedback.

NOTCH (7)

Variable notch control used in conjunction with frequency shift to provide the proper notch setting required to eliminate feedback from instrument. (The more counter clockwise, the deeper the notch, i.e. the notch is out of the circuit when the control is set at full clockwise position.)

REVERB SEND-INSTRUMENT CHANNEL (8)

Controls the amount of reverb signal from the Instrument Channel. Reverb is an echo type effect.

MIC INPUT/LOW-Z (9)

For use with low impedance microphones or high-level sources equipped with a male XLR connector.

Phantom power allows use of microphones that require phantom power.

MIC INPUT/HIGH-Z (10)

For use with high impedance microphones or high-level sources equipped with a 1/4" phone plug.

MIC LEVEL (11)

Controls the overall volume level of the Microphone Channel.

EQUALIZATION-MIC CHANNEL (12)

Specially designed 5-band, active equalization.

REVERB SEND-MIC CHANNEL (13)

Controls the amount of reverb signal from the Microphone Channel.

MASTER REVERB (14)

Controls the overall amount of reverb signal for both the Instrument and Microphone Channels.

PRESENCE (15)

This is an active tone control that boosts the extreme high frequencies. It controls the overall presence signal for both the Instrument and Microphone Channels.

POWER LED (16)

Illuminates when AC power is being supplied to the amp. If amplifier is muted using optional remote switch, the power LED will blink.

POWER SWITCH (17)

Depress the switch to the "on" position. The red LED will illuminate indicating power is being supplied to the unit.

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-I 20 V products only (19)

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/POSTEQ 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.

POWER AMP IN (23)

Used to connect line level signal to the power amplifier.

EFFECTS SEND-MIC (24)

Input for returning signals from external low-level effects or signal processing equipment for the Microphone Channel.

EFFECTS SEND-INSTRUMENT (26)

Output for supplying signals to external low-level effects or signal processing equipment for the Instrument Channel.

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.
