Balanced Inputs
Balanced input wiring requires two conductors with shield (22-gauge is the most common). The use of
crimp type spade lugs is highly recommended for permanent installations. At the input section located on
the rear of the amplifier, wire the “hot”/positive lead to the “+” terminal, the “common”/negative lead to the
“-” terminal and the shield/drain to the “ground” terminal (Figure 3).
The XLR inputs (+4 dB balanced line level) can be utilized with standard 3-pin XLR male to female patch
cables to accommodate outputs from a mixer, equalizer, or crossover when the amplifier is used as a
portable sound system amplifier.
