The   

 is fitted with a universal 

 connector. Into this connector one should always insert a heavy duty 

 AWG 3

conductor line cord with a conventional AC plug with a ground pin. This line cord should be connected to an independent mains circuit

capable of supporting at least 15 amps continuously or greater. This is particularly critical for sustained high power applications. If the

socket used does not have a ground pin, a suitable ground lift adapter should be used and the third wire grounded properly. Never

break off the ground pin on the 3 conductor line cord. The use of extension cords should be avoided, but if necessary, always use a

three-wire type with at least a 

 AWG wire size. The use of lighter wire will severely limit the power capability of this amplifier.

Always use a qualified electrician to install any necessary electrical equipment. To prevent the risk of shock or fire hazard, always be

sure that the amplifier is properly grounded.

This switch is used to either ENABLE or DEFEAT the 

 compressor.

are connected to dual OP AMP circuitry which offers very low noise and extremely high common mode rejection ratio to minimize

outside interference!

Between the two XLR connectors is a recessed switch (13) which allows the user to select the desired polarity (phase) of the

XLR inputs. This switch is a push-push type and a small diameter “tool” is required to select the desired position. Set to the out

(default) position, the polarity is pin   positive, pin   negative, and pin   ground. This is the polarity found on most Peavey power

amplifiers. Although this is not the world “standard” (IEC) polarity, it was chosen by Peavey more than 20 years ago, and thus we

offer this polarity to be consistent with products both past and present. If this amplifier is used with other competitive products which

use the IEC standard polarity, then the   position of switch (13) should be selected yielding pin   positive, pin   negative, and pin

 ground. As with any electronic gear, polarity (phasing) is important because the loudspeaker enclosures associated with this

power amplifier must be in phase with any other loudspeaker enclosures associated with other power amps. If one loudspeaker

system were to “push” while the other “pulls”, then a serious sound “cancellation” could result. Changing the setting of the polarity

switch has the same effect as reversing the polarity of the loudspeaker connections at the output.

in the center of the “combo” connectors are also connected to a unique 

balanced” input circuitry. When used, these 

 jacks are not “chassis grounded” but connected to ground through a relatively low

impedance circuit which is part of a “ground loop” elimination circuitry associated with the input. This feature will normally allow “hum

free” operation when relatively short 

 cable patches are made to this input from various outputs on this amp and other equipment

that share the same rack with this amp. This “quasi-balanced” circuit is “automatic”, and is virtually invisible in normal usage. It can

not be defeated.

Each channel also has a female phone jack (14) labeled 

 This jack offers a very flexible patching capability. When the

XLR input connectors (11) are used, then this 

 jack is the output of the electronic balanced input circuitry, and as such can be

used as a “line out” to connect to the other input jack on this amplifier or other amps in the same rack. Thus one balanced mixer feed

can be connected to the amp via the XLR connector and then further distributed locally via the 

 jack. Alternatively, when the 

phone jack input (12) is used as the input, then the 

 jack becomes a “bridged” input to it (similar to a Y-cord), again allowing this

input signal to be patched to the other input jack on this amplifier or other amps in the system.
