Operating Manual - nX, nXe, and nXp 150W/75W Power Amplifiers
 4 nX FRONT PANEL FEATURES (all models)

4.1 Mounting Holes

– Four front panel mounting holes for standard a 19" equipment rack.

4.2 Air Vents

– Cool air enters in through the amplifier sides and is blown out the front.
4.3 Factory Reset Switch, Sleep Mode, Disable Mode
used to perform a factory reset. It is also used to set sleep mode and disable user controls (see
below). To perform a factory reset and return all amplifier settings to their original factory
defaults, use a pencil point or equivalent to press and hold the switch during power up until all
channel LEDs sequence from bottom to top. Factory reset will not erase stored user presets.
Releasing the switch before the LED sequence is complete will cancel the process. Upon
completion, all LEDs turn off and the amplifier resumes normal operation.
Setting Sleep and Control Disable Mode - The factory reset switch is also used to select
one of four sleep and user control disable modes as shown to the right. The default status is
Sleep and Disable OFF (Mode 1). To advance to the next mode, press and hold the factory
reset switch when the amplifier is fully on. The four possible mode combinations will cycle
through and repeat. To select a mode, release the switch when the desired mode is displayed.
The Disable LED is lit any time the power switch and rear panel level controls are disabled,
either by selecting disable mode from this switch or from software.
Sleep Mode Status Indicator: The blue sleep LED will turn on during the mode-selection process whenever sleep mode would
be enabled upon release of the reset switch, but it will turn back off as soon as the reset switch is released. The sleep LED re-
mains off unless the amp goes to sleep due to audio inactivity. To view whether sleep mode is currently active or not, quickly
press and release the reset switch. If sleep mode is active (mode 2 or mode 3 as shown above) the blue sleep LED will light up.

4.4 Bridge Mode LED Indicator

BRIDGE - This green LED indicates when each channel pair is configured to BRIDGE mode from the back panel
switch. When set to bridge mode, only the odd numbered input and level control is used for that channel pair.

4.5 Channel LED Indicators

TEMP - This yellow LED turns on when an amplifier channel has reached an operating temperature that is 80% of its
maximum safe range, and the cooling fan is at its maximum speed. The LED lights dimly at first and will glow brighter if the
temperature increases.
CURRENT - This green LED lights proportionately with the output current delivered to the speaker load.
SIGNAL - This green LED lights when the output voltage reaches -18dB from full output.
CLIP/MUTE - CLIPPING: The red LED indicates clipping when speaker output is 1dB below rated output, or when the
input preamp signal is clipped. MUTE: The LED indicates mute when the channel is muted or when its level control is fully attenu-
ated. Additionally, the Clip/Mute LED is used along with the Protect LED to indicate an output DC fault (see

section 14).
