Front Panel Features
NetPA U 8001 SUB Front Panel
Power/Standby LED — A single LED that lights green when the unit is on and active,
and lights amber when:
• The unit is powering up and booting.
• The unit is in standby mode, which turns off all outputs from the amplifier although
the amplifier still receives power.
• DC voltage is detected (see
This LED unit flashes amber when an "Identify Device" request is sent to the unit via
Dante Controller, and the Link Indicator LED located on the rear panel blinks green.
Once the cycle has been completed, the LED returns to normal.
NOTE: Power indicator LED may light amber for a short time after the removal
of AC power. This is normal.
Over Temp Indicator — A single LED that lights red when the amplifier has exceeded
the maximum recommended operating temperature. The amplifier recovers once the
unit has sufficiently cooled down (see Troubleshooting).
Channel Status LEDs — Two rows of two LEDs on the NetPA U 8001 SUB that
represent amplifier channels.
Limiter/Protect LED — This LED lights red when the channel is in protection

mode, which is triggered by any of the limiter protection circuits such as:
• When the channel is in an overload situation.
When the output short circuits.
•
• When digital clipping is detected on the output of the DSP going into the
amplifier channel.
When the channel overheats.
