A “biamped” system is one in which low frequency and high-frequency signals are reproduced by separate power amplifiers and speaker enclosures. Biamped systems provide increased headroom, greater clarity, and superior power handling. LOW RANGE OUTPUT (11) Provides a post-crossover low range signal. HIGH RANGE OUTPUT (12) Provides a post-crossover high range signal. Signals which appear at this jack may be processed by the chorus circuit. NOTE: Signal level of high and low range crossover outputs is controlled by the post gain control. CHORUS IN/OUT SWITCH (13) Is used to activate/defeat the chorus circuit. To activate the circuit, depress the switch to its “in” position. NOTE: Chorus footswitch “overrides” push switch. RATE CONTROL (14) Controls the sweep rate (frequency) of the chorus effect. DEPTH CONTROL (15) Controls the depth (intensity) of the chorus effect. PREAMP OUT/POWER AMP IN (16) These jacks are provided for in-line patching of effects devices. To patch an effects unit, connect the Preamp Output 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. Connect the 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. DDT COMPRESSION LED (17) The amplifier is equipped with the patented DDT compression circuit (U.S. Patent 4,318,053). The compression circuit eliminates audible power amp clipping, reduces distortion, and protects the loudspeaker. In use, the Compressor LED may occasionally illuminate, indicating that the compressor is engaging to prevent distortion. If the LED is continuously illuminated, Gain control or Low EQ control settings should be reduced to prevent possible loudspeaker damage. POWER LED (18) Illuminates when AC power is being supplied to the amp. POWER SWITCH (19) Depress the switch to the “On” position. The red pilot light (LED) will illuminate indicating power is being supplied to the unit. TNT’ 115 125 VAC er.Hj SCO w*t IS 21 22 MADE IN U.S.A.

LINE CORD (120V PRODUCTS ONLY) (21) 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. GROUND SWITCH (22) 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. CHORUS REMOTE SWITCH JACK (23) Provided for the connection of the optional remote footswitch. The footswitch is used to activate/defeat the chorus circuit.
