About this Guide
This guide describes the installation and operation of the NetPA 502 AT and
NetPA 1001-70V AT audio power amplifiers. Throughout this guide, both models may be
referred to collectively as the NetPA AT.
Overview
The Extron NetPA 502 AT and NetPA 1001-70V AT are ENERGY STAR® qualified half rack
1U, convection-cooled power amplifiers featuring Dante digital audio networking. They
deliver two channels of 50 watts into 4 ohms, or a single channel of 100 watts at 70 volts.
NetPA AT amplifiers can receive audio from Dante-equipped audio processors over a
standard local area network, greatly simplifying the cabling infrastructure for sharing audio
across multiple rooms or floors in a building. In addition to amplifying incoming Dante audio,
NetPA AT amplifiers feature line level outputs that can simultaneously feed an additional
speaker zone or audio system. They feature an Extron exclusive, highly efficient, advanced
Class D amplifier design, plus patented CDRS - Class D Ripple Suppression that provides
improved signal fidelity over conventional Class D amplifiers.
The NetPA 502 AT two channel amplifier delivers 50 watts rms per channel into 4 ohms or
25 watts rms per channel into 8 ohms. The NetPA 502 AT is ideal for amplification of voice
or program content to stereo speakers, or two sets of 8 ohm ceiling speakers in a dual zone
application. The professional grade amplifier also features greater than 90 dB signal-to-noise
ratio and less than 0.1% THD+N.
The NetPA 1001-70V AT mono amplifier delivers 100 watts rms for 70 volt high impedance
speaker systems in voice reinforcement and distributed audio applications. The professional
grade amplifier features greater than 90 dB signal-to-noise ratio and less than 0.1% THD+N.
The NetPA 1001-70V AT also includes a switch-selectable, high pass filter that rolls off
frequencies below 80 Hz to prevent saturation of speaker transformers.
Dante enables audio system scalability over a local area network using standard Internet
protocols. Dante technology distributes audio channels at 24-bit/48 kHz over a single
Gigabit Ethernet link with extremely low latency. Dante-enabled Extron digital signal
processors feature a built-in four-port Gigabit switch that provides direct interconnection of
multiple units to create larger, cost-effective audio matrixes.
Setting up a network of Extron Dante-enabled products, including the NetPA AT amplifiers,
requires Dante Controller software as well as DSP Configurator Software. Dante Controller is
used to easily assign an output from a Dante-equipped digital signal processor, such as the
Extron DMP 128 Plus AT, to an input on a NetPA AT amplifier.
NetPA AT Series User Guide • Introduction
1
The ENERGY STAR qualified NetPA AT amplifiers are energy efficient products that conserve
energy and reduce costs. They include an auto power-down feature that automatically
places the amplifier into standby after 25 minutes of inactivity.
The NetPA 502 AT and NetPA 1001-70V AT can output incoming Dante channels as line
level signals to simultaneously feed the audio into another speaker zone or audio system.
Both amplifiers also include recessed, detented level controls located on the rear panel
to prevent tampering. These controls facilitate adjustment of audio system gain structure,
or setting an individual level for each zone. Additionally, the NetPA AT amplifiers include
multiple protection circuits that momentarily activate when an abnormal condition, such
as overheating, is detected. An advanced, automatic clip limiter protects speakers from
clipping distortion.

NetPA AT Software
The NetPA AT has both hardware and software controls. Software configuration and
operation are accomplished using a PC running Microsoft Windows 7 or newer. Dante
Controller for Windows from Audinate is required to select and route NetPA AT digital inputs
to all connected Dante‑compatible devices on the same network and to rename connected
devices.
To assist identification of multiple connected NetPA ATs on the network, each NetPA AT
must be renamed using Dante Controller. Dante Controller is available from the NetPA AT
product page at www.extron.com (see Software Download and Installation on
page 11). Digital signal routing can only be done using Dante Controller.
See Rear Panel Features and Connections on page 6 for additional details to
connect via the LAN port.
Software Installation Overview
Download and install the Dante Controller software program.
Download Dante Controller for Windows at www.extron.com (see Dante Controller
for Windows on page 11).
Install Dante Controller.
Rename each NetPA AT as it is placed on the network (when there are multiple
NetPA ATs on the network) (see Rename the NetPA AT on page 16).
NOTE: To avoid confusion, rename each device with a unique identifier. To simplify
renaming, connect only one device to the network at a time. As each device is
renamed, it can remain on the network.

NetPA AT Bus
NetPA AT uses Dante technology to provide high performance digital audio networking
over standard TCP/IP networks. Dante allows audio channels to be transported across
a switched Ethernet data network while meeting the quality requirements of professional
audio.
The audio network can be shared with control traffic or unrelated data traffic. Audio
channels can be unicast or multicast to make the best use of available bandwidth.
The NetPA AT models are receivers (destination) for signals on a Dante network. Receivers
can be located anywhere on the Ethernet network and can be relocated without
reconfiguring the NetPA AT or the network.
Managing Network Traffic
Because Dante devices prefer to use multi-cast routing to distribute audio channels, it is
recommended that, if possible, the audio network be kept separate from the local business
network. For more information on strategies to manage audio network traffic in an integrated
system, refer to the “Multicast Transmit Flow Configuration” section in the Dante Controller
User Guide at the Audinate website, www.audinate.com.
NetPA AT Series User Guide • Dante Configuration and Operation
13
Creating a Physical Dante Network
A physical network is required to share Dante audio channels between a Dante source
device and a NetPA AT. The NetPA 502 AT and NetPA 1001-70V AT have an RJ‑45
connector located on the back panel that accepts a standard network cable.
A DMP 128 Plus‑based Dante network can be configured in a star or daisy chain network
topology using the four port switch and the Dante Controller in switched mode (see
figure 8).
Star network topology places one DMP 128 Plus C AT as the central unit, which connects
directly to as many as three more units. Alternatively, a larger network switch in place
of the central DMP 128 Plus AT, allows more than four NetPA ATs to connect in the star
configuration.

Daisy Chain Topology
Hybrid versions combining the star and daisy chain topologies can be built, but a ring
topology, or any topology that creates a duplicate connection causes a connection failure in
Dante Controller.
NOTE: Connections between ports in either a star or daisy chain network do not need
to be sequential (1 to 2, 2 to 3, 3 to 4), nor do they need to be made between the
same port numbers (1 to 1, 2 to 2, 3 to 3, 4 to 4).
NOTES: At this time, Dante is not compatible with EEE (Energy Efficient Ethernet)
technology. Care should be taken when using a network switch with this technology in
a Dante network.
• If using a managed switch, ensure that it supports disabling EEE on all ports that
are to be used for Dante traffic.
• If using an unmanaged switch, do not use models that support the EEE function, as
it cannot be disabled on these models.
• For more information on this topic, refer to the Audinate website,
www.audinate.com.

Starting Dante Controller
To launch Dante Controller from the computer start menu, select:
All Programs > Audinate > Dante Controller > Dante Controller.
The Dante Controller - Network View screen opens.
If the network has a DHCP server, it receives its IP configuration using the standard DHCP
protocol. On a network without a DHCP server, a Dante-enabled device automatically
assigns itself an address using link local protocol.
Once connected, Dante Controller begins auto-discovery of all Dante devices. While
scanning the network, it also advertises itself to allow Dante‑enabled devices to see and
communicate with it. When the network scan is compete, the Dante Controller Network View screen is displayed (see figure 10).
Figure 10. Dante Controller Network View Screen
The major elements of the Network View screen include:
•
Receivers, representing Dante device inputs, are on the left side running vertically
down the screen (1).
•
Transmitters, representing Dante device outputs, are along the top running horizontally
across the screen (2).
•
Connection points of the receivers and transmitters form a matrix in the lower-right
panel of the screen (3).
NetPA AT Series User Guide • Dante Configuration and Operation
15
Device Name
The default device name of the NetPA AT consists of its model name, followed by the last
six digits of its MAC address (for example, NetPA - 063f70).
Multiple devices on the same network can present difficulty identifying inputs and outputs.
To avoid confusion, rename each device to a unique identifier immediately after you connect
it (see Renaming an Input on page 19).
NOTE: To simplify renaming, connect only one Dante device to the network at a time.
After a device is renamed, it can remain connected.
In addition to renaming the connected device, you can relabel the inputs. Avoid confusing
device names and inputs during operation. If necessary, rename the device and inputs
before proceeding.
Dante Controller Naming Conventions
•
Device labels follow Domain Name System (DNS) hostname rules. Legal characters are
A-Z, a-z, 0-9, and hyphen (-). Device labels must begin with a letter.
•
Dante Tx and Rx labels can be up to 31 characters in length. Label comparisons are not
case-sensitive; “OUTPUT01” and “output01” are recognized as the same connection.
Unicode and non-roman characters are not supported.
•
Tx and Rx channel labels can use any character except equals (=), period (.), or @.
•
Tx and Rx channel labels must be unique on a device but do not need to be unique on
the network.
Rename the NetPA AT
Dante Controller auto-discovers all Dante devices on the network and advertises itself to
allow other Dante-enabled devices to communicate with it. The default device name is the
word “NetPA” followed by the last six digits of the MAC address of the device. Multiple
devices on the same network can present difficulty identifying inputs and outputs. To avoid
confusion, each device must be renamed to a unique identifier.
NOTE: To simplify renaming, connect only one Dante device to the network at a time.
As each device is renamed, it can remain connected.
Ensure the control computer and the NetPA AT are connected to the same network.
All Dante devices on the network are discovered and listed.
1. From the toolbar, select Device>Device View (see figure 11, 1).

Renaming an Input
If the devices are not properly named, Dante network connection points can quickly become
unmanageable in large systems. To better organize the various inputs, it is recommended
you name each input using descriptions of the device they belong to, the location of the
device, or the purpose of the input.
To view the inputs of a receiver device on Dante, click the + sign next to the receiver name
to expand it (see figure 17, 1, for an example).
Figure 17. Expanded Device View — Input and Output Names
The names shown in the Dante Receivers column are extracted from the Dante interface
of the connected device.
•
The NetPA AT input is the Dante receiver (2) labelled NetPA-LectureHall.
•
The named input (3) is INPUT-MONO.
TIP:
To simplify setup and operation of large matrix systems, rename the input
(receiver) lines to better indicate the output to which a receiver is connected.
To rename an input
1. From the Device menu on the Network View screen, select Device View.
Alternatively, press <Ctrl+D> on the keyboard.
2. From the Select a Dante Device drop-down list, select the name of your NetPA AT

Dante Operation
The following topics cover the use of Dante Controller to control and configure the unit.
Selecting Inputs and Outputs for Dante
Dante Controller is used for all network level signal routing of AT bus inputs and outputs.
The digital input channels of the NetPA AT are shown in Dante Controller as receivers. The
digital inputs are available in Dante Controller for routing to other Dante devices.
Routing signals using Dante
Channels received from the network are routed using the Dante Controller Network
View screen Routing tab (see figure 20, 1).
Figure 20. Dante Network View Screen, Routing Tab
NetPA AT Series User Guide • Dante Configuration and Operation
20
The transmitters, listed horizontally along the top of the screen, and the receivers, listed
vertically down the left side, form a matrix whose intersections are the connection points
between the receivers and transmitters.
•
To make the receiver-to-transmitter connection, click once on an intersection.
•
To break a connection, click the icon at the intersection.
One of the following icons appears at each connection intersection, indicating the status of
both the transmitter and receiver channels and the connections (subscriptions):
Icon
Description
Indicates an active connection (subscription).
Indicates a pending connection.
Indicates a broken connection (subscription).
Indicates the transmitting device has been removed from the network or is
switched off.
See the Dante Controller User Guide, available at the Audinate website,
www.audinate.com, for additional information.
NOTE: After making changes to Dante network routing such as connections
(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 configuration such as
sample rates, latency, and clock settings are saved instantly.
Select devices
After the receive channels (1) of the NetPA AT are named, route them to a transmit channel
(2) on the audio network (see figure 21).

Dante Troubleshooting
The most common Dante troubleshooting issues occur when no devices are discovered by
the Dante Controller software, or routing is not successful or is prevented. Both issues occur
when software is not able to properly discover devices operating on the Dante network.
Before moving into more difficult troubleshooting, shut down Dante Controller and reconnect
the Ethernet cable connecting the PC to the Dante network. Restart the Dante Controller
software. This can be enough for the software to reacquire the Dante network.
If the problem persists, perform the following troubleshooting procedures in the order
presented.
Simplifying the Network for Troubleshooting
If further troubleshooting of Dante discovery is necessary, begin by simplifying the network:
1. Connect the PC to the NetPA AT port.
2. Use Dante Controller to check if the issue was resolved before moving on to network
interface troubleshooting.
3. If the issue is resolved, add connections and hardware one at a time, checking for
proper operation after each addition, until the point of failure is discovered (typically a
bad cable or invalid redundant configuration).
Troubleshooting the Network Interface
If the issue is still present after simplifying the network, continue to diagnose the PC network
connections as described below. Check Dante Controller after each step to see if the
problem is resolved.
1. Open the Configure Dante Interface dialog box by clicking the Choose a
Dante Interface icon
on the Dante Controller main screen (see figure 28, 1).
Be certain the correct LAN connection is selected (the PC LAN port physically
connected to the AT network) and note the IP address.
Figure 28.
Configure Dante Interfaces Dialog Box
2. If it is on, turn off the PC wireless adapter. Disable all connections except the LAN
port connected to the Dante network. (Verify this is the correct port by checking the IP
address shown in step 1 above.)
3. Turn off all anti-virus and firewall software on the computer.
4. Enable DHCP on the remaining network connection. This forces the computer to
acquire an IP address from the Dante interface.

Additional Troubleshooting
For further help, see Dante Troubleshooting in the Dante help file. To access the Dante help
file, do any of the following:
•
Click the Help icon in the upper-right corner of the Dante screen (see figure 29, 1,
below).
•
Select Online Help or Offline Help from the Help menu (2) on the Dante
screen.
•
Press the <F1> key on the computer keyboard.
Figure 29. Accessing the Dante Help File
Resetting the NetPA AT
The NetPA AT utilizes DHCP addressing by default.
A recessed Reset button on the rear panel (see figure 2, G, on page 6) initiates
a reset mode. Reset sets the IP addressing mode to DHCP (Dante default), clears the
previous IP address, and resets the device name to default.
NOTE: Initiating a reset while the NetPA AT is connected to a transmitting device severs
that connection.
To reset the NetPA AT, press and hold down the Reset button for 10 seconds until both of
the rear panel RJ-45 Ethernet port LEDs blink twice.
NOTE: When the NetPA AT is first powered on, or reset, the default name shall be
“NetPA-xxxxxx” where xxxxxx are the last six digits of the MAC address of the unit.

Mounting of the NetPA AT
The NetPA AT can be mounted in the following ways:
•
Set on a table
•
Mounted on a rack shelf
•
Mounted under a desk or tabletop
The half rack width, 9.5 inch (24.1 cm) deep enclosure is designed for inconspicuous
under‑table placement using the UTS 100 Series Under Table Shelf System or MBU 125
Low-Profile Mount Kit, available separately.
Tabletop Use
Each NetPA AT is supplied with rubber feet (not installed). For tabletop use, attach a
self‑adhesive rubber foot to each corner of the bottom of the unit.
UL Rack Mounting Guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the
NetPA AT in a rack.
1. Elevated operating ambient temperature — If the equipment is installed in a closed
or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore, consider installing the
equipment in an environment compatible with the +122 °F (+50 °C) maximum ambient
temperature (Tma) specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (such as the use of power strips).

Rack Shelf Mounting
For rack mounting, do not install the rubber feet. The NetPA AT can be mounted on a
19 inch Universal 1U, UTS half rack, or basic rack shelf.
To rack mount the NetPA AT on a rack shelf:
1. If rubber feet are installed on the bottom of the NetPA AT, remove them.
2. Mount the NetPA AT on the rack shelf, using two 4-40 x 3/16 inch screws in opposite
(diagonal) corners to secure the unit to the shelf (see figure 34).
ATTENTION:
• Using screws longer than 3/16” will damage the unit and void the warranty.
• L’utilisation de vis plus longues que 3/16” endommagera l’unité et annulera la
garantie.
TIP:
Where access to the screws mounting the device to a shelf is diffficult,
mount the device to the shelf prior to installing the shelf in the rack..

Under-desk Mounting
The table or wall mounting brackets extend approximately 1/4 inch (6.4 mm) above the top
surface of the enclosure. This design allows for an air space between the enclosure and the
surface to which it is mounted (see figure 35).
Mount the NetPA AT under a desk or table as follows:
1. Attach the MBU 125 brackets.
2. Hold the unit with the attached brackets against the underside of the table or other
furniture. Mark the location of the screw holes of the bracket on the mounting surface.
3. Drill 3/32 inch (2 mm) diameter pilot holes, 1/4 inch (6.4 mm) deep in the mounting
surface at the marked screw locations.
4. Insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting
surface until just less than 1/4 inch of the screw’s head protrudes.
5. Align the mounting screws with the slots in the brackets and place the unit against the
surface, with the screws through the bracket slots.
6. Slide the unit slightly forward or back, then tighten all four screws to secure it in place.

Other Mounting Options
The NetPA AT can also be installed under furniture using the UTS 100 and UTS 150
under-table shelf system.

Defeatable Auto Power-down Timer
The auto power-down timer determines whether or not the NetPA AT enters standby mode.
The amplifier powers down if the input signal remains below the input signal detection
threshold for about 25 minutes.
The timer resets whenever the input signal exceeds the input signal detection threshold.
Resetting the timer starts a new 25-minute countdown until the amplifier powers down.
Resetting the timer also causes an amplifier that is already powered down to “wake up” or
power back up.
There may be times when it is desirable to bypass (disable) the auto power-down timer.
Examples of when defeating the auto power-down circuit might be required include:
•
If the amplifier is used in a paging system. When the amplifier has already powered
down, the first syllable might be cut off as the amplifier wakes up from standby mode.
•
If the input signal is so quiet that the level remains below the input signal detection
threshold for 25 minutes, the timer cuts the audio in the middle of playback by placing
the amplifier into standby mode.
To defeat the auto power-down timer, follow these instructions:
1. Disconnect power from the amplifier.
WARNING: Electric shock hazard. Disconnect power to the product before
opening the case.
AVERTISSEMENT : Risque de choc électrique. Débranchez l’alimentation
secteur du produit avant d’ouvrir le boîtier.
2. Remove the nine cover screws that secure the top enclosure cover to the NetPA AT.
Three screws on top and three screws on each side (see figure 36).
ATTENTION:
• Exercise caution when removing the screws to avoid stripping the screw
heads.
• Soyez prudent en retirant les vis afin d’éviter d’abîmer les têtes de vis.

4. The circuit board nearest the rear of the NetPA AT has a jumper to enable or disable
the power-down timer. By default, the jumper is set to enable (the jumper set on the
leftmost pins). Setting the jumper on the rightmost pins disables the power-down timer.
ATTENTION:
• Do not touch the electronic components or the connectors on the backplane
or on the circuit boards without being electrically grounded.
• Ne pas toucher les composants électroniques ou les connecteurs sur la carte
mère ou sur les circuits imprimés sans être électriquement relié à la terre.
5. Enable the power-down timer by placing the jumper on the two leftmost pins. Disable
the power-down timer by placing the jumper on the two rightmost pins (see figure 37).
