input (100 VAC to 240 VAC, 50-60 Hz) to the internal, auto-switching power supply.
This connector may be replaced by the Flexible Conduit Adapter Kit (see
Conduit Adapter Kit on page 10).

3.5 mm captive screw ports to input up to four balanced or unbalanced line level or
microphone level signals.
NOTE: Inputs remain active during standby. Phantom power is not available on any of
the inputs (see figure 14 for captive screw connector wiring).

Channel Status indicators (see figure 13) — Two double-stacked LEDs on the
3
NetPA U 1002 units and four double-stacked LEDs on the NetPA U 1004 units. The top
red LEDs are used for Limiter/Protect status, and the bottom green LEDs are for signal
status.
The LEDs function the same as the LEDs on the front panel.
Line Outputs (see figure 13) — Connect up to two or four 3-pole 3 mm captive screw
4
connectors in order to output up to two or four balanced or unbalanced line level output
signals.
NOTE: The outputs do not remain active when the amplifier is in standby. For
applications where the line and Dante outputs may be used independently during
long periods of no amplifier activity, such as when the unit is being used as both
an amplifier and off/on-ramp to the Dante network, the auto-standby timer must
be disabled and the amplifier must not be forced into standby.

to the RS-232 port to remotely monitor and control the unit. Connect a 3.5 mm 2-pole
captive screw connector to the standby port to remotely place the amplifier in standby
mode (see figure 16 on the next page)).
Standby mode is activated when the Standby pin is connected to the G pin. Standby
mode turns off all the outputs, although the amplifier still receives power. The power
LED on the front panel lights amber when the amplifier is in standby mode.
The amplifier enters standby mode when one of the following happens and are
prioritized as
follows:
• Activation of the remote standby port (done by shorting the STANDBY pin to the
ground pin).
Through the PSAV (Standby)
