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).

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

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

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

+122 °F (+50 °C).

• 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).

Figure 5. Speaker Output Port and Wiring Diagram

ATTENTION:

• You must use Class 2 wiring for this output to comply with UL requirements.

• Vous devez utiliser le câblage de classe 2 pour cette sortie an de vous conformer aux exigences UL.

• Do not tie channel output pins to each other or to ground. Doing so will short out the outputs, damage the

amplier, or both.

• Ne pas lier les sorties 1 et 2 des canaux entre elles ou à la terre. Les sorties pourraient être court-circuitées et/

ou l’amplicateur pourrait être endommagé.

• To avoid risk of damage to the amplier or the speakers, always check that speaker loads are appropriately

wired to the amplier.

• Pour éviter les risques de dommages à l’amplicateur ou aux haut-parleurs, vériez toujours que les charges

des haut-parleurs sont correctement câblées à l’amplicateur.

Step 5 — AT Port

Connect an RJ-45 connector to the AT port to connect and

communicate with the Dante network. It is also one of the

interfaces DSP Congurator uses to communicate with the

amplier. The Link LED indicates when a connection is made.

Go to Configure Dante Device Settings on page 5 for

information on Dante settings. See the image to the right for

wiring.

Step 6 — Powering on Ampliﬁer and Adjustments

Ensure all sources connected to the amplier inputs are muted to

avoid potential speaker damage during power-up.

Reconnect all the power cables and switch on the rest of the

equipment before powering on the power amplier. The amplier

boots-up for up to 10 seconds as the front panel LED ashes green.

Once the boot-up sequence is complete, the amplier takes more time to sync with the Dante network, and begin the

playback of streamed content. The front panel LED lights green after approximately 20 seconds.

ATTENTION:

• The amplier must be powered on last.

• L’amplicateur doit être mis sous tension en dernier.

Step 7 — Checking LEDs

Check the Limiter/Protect and Signal LEDs on the front and rear panels to see if any problems are encountered (see “Front

Panel Features and Troubleshooting” in the NetPA U 8001 SUB User Guide for more information).

Double-check the correct load is connected and properly wired to the rear panel connection (see Speaker Wiring on page 3

for more information).

Step 8 — DSP Conﬁgurator Software Installation

There are no hardware controls for the NetPA U 8001 SUB. Conguration is performed using Extron DSP Congurator

software, while control is performed via SIS commands. To learn about full computer requirements, see the DSP Congurator

Dante Network Setup

Use a standard Ethernet cable to connect a NetPA U 8001 SUB amplier to a Dante network via the AT port. Launch the

Dante Controller program.

Dante Controller automatically discovers all Dante devices on the network and allows other Dante-enabled devices to

communicate with it. The default device name is the model name followed by the last six characters of the device MAC address

(for example, NetPA-U-xxxxxx). Multiple devices on the same network can present difculty in identifying inputs and outputs. To

avoid confusion, rename each device to a unique identier.

NOTE: To simplify setup, connect only one Dante device to the network at a time.

Dante Controller Operation

Dante Transmitters and Receivers

A Dante network is comprised of transmitters that output digital audio onto the Dante network and receivers that receive

digital audio input from the Dante network.

• Transmitters output digital audio from the device onto the audio network.

• Receivers take in digital audio from the audio network into the device.

Network View Layout

In the Dante Controller software, Dante transmitters are

listed horizontally across the top of the Network View

(1), while Dante receivers are listed vertically on the left

side of the window (2). Creating a link in the connection

matrix routes audio from a transmitter to a receiver (3).

Routing Devices

1. To show the transmitters of a Dante device, click

the +box next to the desired device in the Dante

Transmitters panel, such as

NetPA-U-Classroom-1 (1). The +changes to a –

sign when the details for the device expand.

2. To show the receivers of a Dante device, click the

+box next to the desired device in the

Dante Receivers panel, such as DMP128P-PD-Control-Room (2).

3. Click the intersection of the desired subscription (discrete connection) between a transmitter and a receiver (3). A check

mark at the intersection indicates the subscription is made. A check mark also appears next to the receiver channel.

NOTE: A receiver can subscribe to only one transmitter. A transmitter can connect to multiple receivers.

4. To undo routing, click the junction again to disconnect the receiver from the transmitter.

NOTE: After making changes to Dante network routing such as subscriptions, device names, or channel labels, wait at

least 5 seconds before disconnecting or powering down the devices. This ensures that the new information is properly

saved to those devices. Device-level configurations, such as sample rates, latency, and clock settings are saved

instantly.

For more information on conguring a NetPA U 8001 SUB unit in Dante Controller, see the “Dante Controller” section of the

NetPA U 8001 SUB User Guide found on www.extron.com.

Gain Structure

The input sensitivity of the NetPA U 8001 SUB amplier is 0 dBFS. To achieve maximum output power without degrading audio

clarity, the peak signal level on the meter at the amplier channel output attenuators should be set at—or as close as possible—to

0 dBFS.

The default conguration of the DSP blocks are as follows:

• Input Signal Chain

• All analog input gains (ANG GAIN) are set to 0 dB.

• All Dante inputs do not have an input gain inserted.

• All processors are disabled.

• All input pre-mix gains are set to 0 dB.

• Mix Points

• Analog inputs are mixed at -6 dB to the amplier output channel and mixed at 0 dB to the AT outputs.

• AT inputs are mixed at -6 dB to the amplier output and at 0 dB to the Line outputs.

• Output Signal Chain

• All output trims are set to 0 dB.

• Amplier channel output attenuator is set to -24 dB.

• Line and AT output attenuators are set to 0 dB.

Setting-Up Gain Structure

Setting proper gain structure is necessary to ensure maximum audio clarity and amplier output performance. To set-up gain

structure, follow the steps outlined below, using a calibrated pink noise source.

1. Ensure all pre-mix gain and output trim blocks are set to 0 dB.

2. If mixing a stereo input to the subwoofer output, set mix point gain to -6 dB for each input channel. If mixing a mono input to

the amplier output, set mix point gain to 0 dB.

3. Adjust the Line Input ANG GAIN blocks so the output meter reads -17 dBFS.

4. Adjust the output attenuators, so the output meter reads -17 dBFS.

Refer to the NetPA U 8001 SUB User Guide found on www.extron.com for more details on setting-up gain structure.

NOTE: When setting levels, pay attention to avoid digital clipping.

Crossover Filter

One lter block is available for each output channel. This lter block offers a crossover lter that links the parameters of two (one

high-pass and one low-pass) or three (two high-pass and one low-pass) output lters. To apply a crossover lter to the output

channel, follow the procedure found in the NetPA U 8001 SUB User Guide.
