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 amplier model is 2RU, and is designed to t in a standard 19-inch equipment rack. Use four screws when mounting

the amplier 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 amplier’s chassis to the rack enclosure. This is accomplished using star type lockwashers on the four

rack mounting screws, placed between the amplier chassis and the rack rails. These star washers will penetrate through the

amplier and rack rail nish to adequately ground the chassis to the rack.

2.7 Cooling

Air vents on the amplier front and side panels must have access to free owing 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 amplier. See

the BTU/hr chart below for amplier thermal output characteristics.
