instructions, and specifications.

The Extron NetPA U 8001 SUB is an ENERGY STAR-qualied, Dante-enabled subwoofer amplier with onboard audio DSP,
designed specically for use with the Extron SF 10C SUB in-ceiling subwoofer speaker, as well as other 8, 4, or 2 ohm
subwoofers with similar power requirements. The NetPA U 8001 SUB can deliver up to 800 watts at 8 ohms, 650 watts at 4 ohms,
or 325 watts at 2 ohms.

The NetPA U 8001 SUB is 1U high, half-rack width, and rack-mountable. The amplier has mounting holes for 9-inch (22.86 cm)
and deeper rack shelves, and is plenum-rated with an optional ex conduit adapter. The unit is convection-cooled.

This guide provides instructions for an experienced installer to set up and operate the NetPA U 8001 SUB subwoofer amplier.
For full installation, conguration, and operation details, see the NetPA U 8001 SUB User Guide available at www.extron.com.

Installation Steps

Step 1 — Mounting onto a Rack

Turn off all of the equipment and disconnect it from the power source. Mount the amplier as required. It can be securely mounted
in a variety of locations, using optional Extron Mounting Brackets and accessories (see the Extron website for compatible
optional mounting accessories), or using the included three-piece bracket system. The brackets do not come attached to the
amplier.

The following sections describe two methods of rack-mounting the ampliers.

Rack Ear Mounting (Single Unit)

The NetPA U 8001 SUB amplier ships with a set of rack ears, so this half-rack width amplier can be installed in a full-rack width
space. Mount the amplier with rack ears as follows:

1. If the amplier has its rubber feet installed, remove them.

2. Attach the rack brackets (one long and one short) to the sides with the four provided #6 machine screws (

1

).

3. Insert the amplier into the rack and align the holes in the rack ears with the holes on the rack.

4. Secure the amplier to the rack using the four provided 10-32 x 3/4-inch screws (

2

).

Bridge Plate Rack Mounting (Side-by-Side)

The NetPA U 8001 SUB ships with a bridge plate connector to connect two ampliers together and form a full-rack width unit.
Mount and connect two ampliers as follows:

1. If the amplier has its rubber feet installed, remove them.

2. Position two ampliers upside down and side-by-side as shown below.

3. Use the bridge plate connector and the four provided #4 machine screws to connect the two units together (

4. Attach the two short rack ears to the units with the four provided #6 machine screws (

2

).

5. Insert the amplier into the rack and align the holes in the rack ears with the holes on the rack.

6. Secure the amplier to the rack using the four provided 10-32 x 3/4” screws (

Figure 2. NetPA U 8001 SUB Bridge Plate Rack Mounting

In addition to rack-mounting, the NetPA U 8001 SUB can also be mounted directly to the SF 10C SUB using the mounting
hardware that is included with the speaker. Please see the NetPA U 8001 SUB User Guide for detailed setup instructions.

Ventilation Recommendation

Excessive heat decreases the optimal lifetime of the power amplier. An
Over Temp LED indicator on the front panel of the amplier lights red when

Vent Space

the recommended operating temperature has been exceeded.

NetPA Ultra ampliers need to be arranged in a rack environment, so that
the environment around the amplier does not reach or exceed +122 °F (+50
°C). No more than four ampliers in a group should be stacked without a

Vent Space

ventilation opening between the groups.

The NetPA U 8001 SUB can also be arranged above or below a non-NetPA
Ultra device, but in any case, the environment should never reach or exceed

Vent Space

Vent Space

+122 °F (+50 °C).

Figure 4. Remote Volume Control and Standby Ports

• Standby mode is forced when the Standby pin is connected to the second G pin. The power LED on the front panel

lights amber when the amplier is in Standby mode, indicating that the amplier is still receiving power despite the fact
that it has turned off all the outputs.

NOTE: The enabling and disabling of the auto-standby timer is handled through SIS or DSP Configurator. For more

details, consult the NetPA U 8001 SUB User Guide.

• Connect a 3.5 mm, 3-pole captive screw connector to remotely control the volume via SIS commands, and connect a 3.5

mm, 2-pole captive screw to place the amplifier into Standby mode.

Protocol for the RS-232 port:

• 38,400 baud • 1 stop bit • 8 data bits • no parity

Step 4 — Speaker Wiring

Connect a 2-pin, 5 mm captive-screw connector for speaker output on the NetPA U 8001 SUB amplier. The port has a screw
ange to secure the plug to the connector (see figure 5 to learn how to wire the captive screw connector).
