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 an 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
amplier, 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’amplicateur pourrait être endommagé.
• To avoid risk of damage to the amplier or the speakers, always check that speaker loads are appropriately
wired to the amplier.
• Pour éviter les risques de dommages à l’amplicateur ou aux haut-parleurs, vériez toujours que les charges
des haut-parleurs sont correctement câblées à l’amplicateur.
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 Congurator uses to communicate with the
amplier. 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 amplier 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 amplier. The amplier
boots-up for up to 10 seconds as the front panel LED ashes green.
Once the boot-up sequence is complete, the amplier 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 amplier must be powered on last.
• L’amplicateur 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. Conguration is performed using Extron DSP Congurator
software, while control is performed via SIS commands. To learn about full computer requirements, see the DSP Congurator

Creating a Physical Dante Network
A physical network is required to share Dante audio channels
among Dante-enabled devices like those found in the NetPA
U 8001 SUB. Other devices capable of sending and receiving
audio over a Dante network must be on the same physical
network in order to communicate with Dante (see gure 7 on
the right for an example of a Dante network).

Dante Network Setup
Use a standard Ethernet cable to connect a NetPA U 8001 SUB amplier 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 difculty in identifying inputs and outputs. To
avoid confusion, rename each device to a unique identier.
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.

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.

NetPA U 8001 SUB • Setup Guide (Continued)
Gain Structure
The input sensitivity of the NetPA U 8001 SUB amplier is 0 dBFS. To achieve maximum output power without degrading audio
clarity, the peak signal level on the meter at the amplier channel output attenuators should be set at—or as close as possible—to
0 dBFS.
The default conguration 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 amplier output channel and mixed at 0 dB to the AT outputs.
• AT inputs are mixed at -6 dB to the amplier output and at 0 dB to the Line outputs.
• Output Signal Chain
• All output trims are set to 0 dB.
• Amplier 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 amplier 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 amplier 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.
