2.4 Remote Control Wire
Remote DC level control (all models) - Unshielded bell or telephone wire is sufficient for DC level control, as is CAT5 cable.
The V+ and GND pins from one amplifier channel can be shared with other remote DC level controls wired to the same ampli-
fier, however do not connect this ground to any external grounds.
Remote Standby (nXe and nXp only) - This is a logic level signal, use unshielded low gauge wire.
Fault (nXe and nXp only) - This is also a logic level signal, unshielded low gauge wire is adequate.
Preset (nXe and nXp only) - This is also a logic level signal, unshielded low gauge wire is adequate.
Data (nXe and nXp only) - Four conductor telephone wire is suitable, as well as CAT5, but if shielded wiring is used be sure
to ground the source end of the shield. Under no circumstances should shielding be left unconnected to ground, as the added
line capacitance will degrade the data signal. Maximum data cable distance is 1,000 ft (305m).
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 1RU, 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). 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.
