instructions, and specifications.

The NetPA Ultra Series is a series of DSP and Dante®-enabled audio power ampliﬁers for use in a low-impedance speaker systems or high-impedance line distribution audio systems.

NetPA U 1002 models deliver two channels of 100 watts, and is available in the following conﬁgurations:

• NetPA U 1002 (8 Ω/4 Ω) • NetPA U 1002-70V (70 V) • NetPA U 1002-100V (100 V)

NetPA U 1004 models deliver four channels of 100 watts, and is available in the following conﬁgurations:

• NetPA U 1004 (8 Ω/4 Ω) • NetPA U 1004-70V (70 V) • NetPA U 1004-100V (100 V)

The NetPA Ultra Series ampliﬁers all feature a compact 1U, 1/2-rack enclosure. The ampliﬁers have mounting holes for 9” and deeper rack shelves, and are plenum rated with an optional ﬂex conduit adaptor. The units are convection cooled.

This guide provides instructions for an experienced installer to set up and operate these power ampliﬁers. The setup guide features the NetPA U 1004, but the other ampliﬁers are installed in the same manner. For full installation, conﬁguration, and operation details, see the NetPA U 1004 Series 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 ampliﬁer as required. They 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 3-piece bracket system. The brackets do not come attached to the ampliﬁer.

The following sections describe two methods of rack mounting the ampliﬁers.

Rack Ear Mounting (Single Unit)

All of the ampliﬁers ship with a set of rack ears, so these half rack-width ampliﬁers can be installed in a full rack-width space. Mount the ampliﬁer with rack ears as follows:

1. If the ampliﬁer 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 (

3. Insert the ampliﬁer into the rack and align the holes in the rack ears with the holes on the rack.

4. Secure the ampliﬁer to the rack using the four provided 10-32 x 3/4” screws (

Ventilation Recommendation

Excessive heat decreases the optimal lifetime of the power ampliﬁer. An Over Temp LED indicator on the front panel of the ampliﬁer lights red when the recommended operating temperature has been exceeded.

The NetPA Ultra ampliﬁers need to be arranged in a rack environment, so that the environment around the ampliﬁer around does not reach or exceed +122 °F (+50 °C). No more than four ampliﬁers should be stacked one-on-top-of-the-other without an open rack space in between as seen in the image to the right.

The NetPA Ultra ampliﬁers can also be arranged above or below a non-NetPA Ultra device.

STANDBY

Figure 5 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 ampliﬁer is in Standby mode indicating that the ampliﬁer 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 Ultra Series 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 four 4-pin, 5 mm captive screw connector for two channels of speaker output on the NetPA U 1002 group of amplifiers and up to four channels on the NetPA U 1004 group of amplifiers. Each port has a screw flange to secure the plug to the connector. Figure 6 shows how to wire the captive screw connector.

ATTENTION:

• Do not tie channel output pins to each other or to ground. Doing so will short out the outputs, damage the ampliﬁer, 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’ampliﬁcateur pourrait être endommagé.

• To avoid risk of damage to the ampliﬁer or the speakers, always connect low-impedance speaker loads (8 Ω/4 Ω) and

high-impedance speaker loads (70 V) to the appropriately marked output connectors on the ampliﬁer.

• Pour éviter tout risque de détérioration de l’ampliﬁcateur ou des enceintes, connectez toujours les charges de l’enceinte

faible impédance (8 Ω/4 Ω) et les charges de l’enceinte haute impédance (70 V) aux connecteurs de sortie correctement identiﬁés sur l’ampliﬁcateur.

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 Configurator uses to communicate with the amplifier. 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.

Reconnect all the power cables and switch on the rest of the equipment before powering on the power ampliﬁer. The ampliﬁer will boot-up for up to 10 seconds as the front panel LED lights amber.

Once the boot-up sequence is complete, the ampliﬁer takes more time to sync with the Dante network, and begin the playback of streamed content. Once playback begins, the front panel LED lights green.

ATTENTION:

• The ampliﬁer must be powered on last.

• L’ampliﬁcateur 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 Ultra Series User Guide for more information).

Step 8 — DSP Conﬁgurator Software Installation

There are no hardware controls for any of the units in the NetPA Ultra Series. Configuration and control is done using either Extron

DSP Configurator software or SIS commands. To learn about full computer requirements, see the DSP Configurator product page on www.extron.com.

Dante Network Setup

Use a standard Ethernet cable to connect a NetPA Ultra Series ampliﬁer 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 difﬁculty in identifying inputs and outputs. To avoid confusion, rename each device to a unique identiﬁer.

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

Finding a Dante Device IP Address

1. Open Dante Controller.

2. On the Dante Controller-Network View screen, click the Device Info tab.

3. On the Device Info page, locate the name of the NetPA Ultra Series in the Device Name column. The IP address is

located in the Primary Address column. In the example below, the IP address for the connected NetPA Ultra Series is

192.168.254.254.

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.

NetPA Ultra Series Transmitters and Receivers

In the NetPA U 1004, the line output signals are parallel to their respective Dante output signal. The signal being sent out of a line output is the same signal being sent out of its respective Dante output. In the NetPA U 1002, the line outputs are independent of

Dante outputs.

The NetPA Ultra Series AT input channels are Dante receivers because they receive digital audio signal from the Dante network that can then be routed and mixed into a mix matrix. The NetPA U 1004 has four Dante inputs, while the NetPA U 1002 has two Dante inputs.

Figure 9 Device Info Page

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 configuration such as sample rates, latency, and clock settings are saved instantly.
