The Extron NetPA U 2002 SB is an ENERGY STAR-qualied, Dante-enabled power amplier with onboard audio DSP, for use in
low-impedance speaker systems or high-impedance line distribution audio systems.
The NetPA U 2002 SB is 1U high, half rack-width, and rack-mountable. The ampliers have mounting holes for 9” (22.86 cm) and
deeper rack shelves and are plenum-rated with an optional ex conduit adapter. The units are convection-cooled.
This guide provides instructions for an experienced installer to set up and operate the NetPA U 2002 SB power amplier. For full
installation, conguration, and operation details, see the NetPA U 2002 SB 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 2002 SB amplier ships with a set of rack ears, so the 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” screws (2).

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.
The 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 should be stacked without a
ventilation opening between the groups.
The NetPA U 2002 SB 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).

details, consult the NetPA U 2002 SB 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 4-pin, 5 mm captive-screw connector for two channels of speaker output on the NetPA U 2002 SB amplier. Each
port has a screw ange to secure the plug to the connector (see figure 6 on the next page to learn how to wire the captive screw
connector).
Follow the instructions below to congure the rear panel for the NetPA U 2002 SB:
• For stereo modes, connect a 4-pin, 5 mm captive screw connector for two channels of speaker outputs. The port has a
screw ange to secure the plug to the connector.
• For mono modes, connect the same 4-pin, 5 mm captive screw connector but wire only the middle speaker output pins for a
single channel of speaker output (see figure 6 to learn how to wire the speaker output).
ATTENTION:
• Do not connect the speaker output connector to the amplier until the output mode has been set properly (see
“Setting the Output Mode” on the next page for details).
• Ne connectez pas le connecteur de sortie du haut-parleur à l’amplicateur tant que le mode de sortie n’a

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 low-impedance speaker loads
(4 Ω/8 Ω/16 Ω) and high-impedance speaker loads (70 V/100 V) are appropriately wired to the amplier for the
desired mode.
• Pour éviter les risques de dommages à l’amplicateur ou aux haut-parleurs, vériez toujours que les charges de
haut-parleur à faible impédance (4 Ω/8 Ω/16 Ω) et les charges de haut-parleurs à haute impédance (70 V/100 V)
sont correctement câblées à l’amplicateur pour le mode souhaité..
Step 5 — AT Port
Connect a 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 6 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

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 2002 SB User Guide for more information).
Double-check the correct load is connected and properly wired to the rear panel connections (see Speaker Wiring on page 3 for
more information).
Step 8 — DSP Configurator Software Installation
There are no hardware controls for the NetPA U 2002 SB. Conguration is done using Extron DSP Congurator software and
control is performed using SIS commands. To learn about full computer requirements, see the DSP Congurator product page on

environment via the DSP Configurator. The following steps detail how to configure a NetPA U 2002 SB amplifier.
Configure the NetPA U 2002 SB Amplifier
1. Ensure the control computer is connected to either the AT port, RS-232 port, or the rear panel USB conguration port.
2. Start the DSP Congurator software. From the splash screen drop-down list, select NetPA U 2002 SB. Click OK. The main
workspace opens.
3. The software starts in Emulate mode:
a. To create a conguration le ofine and then upload that conguration to a NetPA U 2002 SB unit at a later time, remain
in Emulate mode and save the conguration le.
b. To upload a conguration to the NetPA U 2002 SB unit or download the current conguration from the unit, enter Live
mode. When in Live mode, changes made in DSP Congurator immediately affect the connected NetPA U 2002 SB. To
enter Live mode, click Live at the top of the DSP Congurator workspace, or select Tools >Connect to Device, or
press <F6> on the keyboard.
NOTE: When Live mode is selected, a connection dialog box appears. Select the desired connection type and
follow the on-screen prompts (see the NetPA U 2002 SB User Guide for more information on connecting live to a

Setting the Output Mode
The NetPA U 2002 SB output mode is congured via DSP Congurator and the selection is passed to the amplier. There are six
selectable modes that are divided into two stereo modes and four bridged mono modes.
• Stereo Modes (8 ohm/4 ohm) — Each channel of an output pair behaves independently, and each input can be routed to
any output.
• Bridged Mono Modes — There are four bridged mono modes: two low-impedance (8 ohm and 16 ohm) and two high-
impedance (70V and 100V). The second amplier output is not user-controllable in DSP Congurator.
• 8 ohm bridged — This mode bridges the output pair and sets it for an 8 ohm load.
• 16 ohm bridged — This mode bridges the output pair and sets it for a 16 ohm load.
• 70V — This mode bridges the output pair and sets it for a 70V load.
• 100V — This mode bridges the output pair and sets it for a 100V load.
Bridging occurs in the amplier. The positive pin on Channel 1 becomes the positive pin of the bridged output, and the positive
pin on Channel 2 becomes the negative pin of the bridged output.
When the amplier is set to bridged mono mode, DSP Congurator deletes the Channel 2 amplier output signal chain, including
mix points and output processors.
In the 70V and 100V modes, an 80 Hz, 12 dB/octave high-pass lter is applied to the output lter block by default. The user can
change the frequency and slope of this lter. In all other modes, the high-pass lter is not applied by default.
Configuring the Output Mode
1. Select Tools> Congure Amplier Output Mode to open the Congure Amplier Output Mode dialog box.

NetPA U 2002 SB • Setup Guide (Continued)

Dante Network Setup
Use a standard Ethernet cable to connect a NetPA U 2002 SB 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-9175f2 (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 a
NetPA-U-MainRack (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.

Gain Structure
The input sensitivity of the NetPA U 2002 SB 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 channels 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 a separate input gain placed before the processors.
• All processors are disabled.
• All input pre-mix gains are set to 0 dB.
• Mix Points
• AT inputs 1 and 2 are mixed at 0 dB to their respective Amplier and Line outputs .
• Output Signal Chain
• Amplier output mode is set to stereo, 8 ohms.
• All output trims are set to 0 dB.
• All processors are disabled, except in 70V and 100V output modes. In these modes, a user-modiable, 80 Hz high-pass
lter is applied to the output lter block by default.
• Amplier channel output attenuators are set to -24 dB.
• Amplier Line and AT outputs 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, cross-points, and output trim blocks are set to 0 dB
2. Adjust the Mic/Line Input ANG GAIN blocks so the output meter reads -17dBFS
3. Adjust the output attenuators, so the output meter reads -17 dBFS
Refer to the NetPA U 2002 SB 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.
