2.5 Aux Output Wiring (nXe and nXp only)
The aux outputs are pseudo-balanced, meaning they use single ended signal (+) but with balanced impedance, and can be wired
balanced or unbalanced.
Always use shielded cable for audio signals.
2.6 Mechanical
Each amplifier
model is 2RU, and is designed to fit in a standard 19-inch equipment rack. Use four screws when mounting
the amplifier to the front rack rails. Rear support is recommended for mobile or touring use (see mechanical drawing below).
In some installations where the sound system is exposed to a high level of RF noise or system-induced oscillation, it may be
necessary to ground the amplifier’s chassis to the rack enclosure. This is accomplished using star type lockwashers on the four
rack mounting screws, placed between the amplifier chassis and the rack rails. These star washers will penetrate through the
amplifier and rack rail finish to adequately ground the chassis to the rack.
2.7 Cooling
Air vents on the amplifier front and side panels must have access to free flowing room temperature air. Cool air is drawn in
through the sides and blown out the front. It is not necessary to leave empty rack spaces above or below the amplifier. See the
BTU/hr chart below for amplifier thermal output characteristics.
