Front Panel Icons - NHT M-60 Xd Owner's Manual

FRONT PANEL ICONS:

Standby:
This text illuminates whenever the XdA is in standby. See the Trigger Control section for more
details.
Power:
This text illuminates whenever the XdA is powered up and operational.
Fault:
This text illuminates whenever the XdA detects a fault condition. There are several situations that
can cause this.
If one of the speaker outputs is shorted to each other or ground, the fault light will stay on until the
condition is fixed and the XdA is power cycled. The amplifier channel with the shorted speaker wire
will remain muted until the condition is fixed.
If any of the amplifiers has excessive DC at its output, the fault light will remain on and that channel
will remain muted.
If any of the amplifiers' temperature gets too high for safe operation, the fault light will illuminate and
that channel will mute. To fix the condition, the amplifier must cool off at least 10 degrees C and
then be power cycled.
If any of the amplifiers are driven into clipping, the fault light will flash during clipping. If the amplifier
is driven into clipping excessively, the over current protection will trip and that channel will mute. To
reset this protection, power cycle the XdA.
