• One 400 watt bridged channel into 8 ohms or 16 ohms

NetPA U 2002 SB User Guide • Introduction 1

• ENERGY STAR qualified amplifier with defeatable auto-standby and fast wake

up — The NetPA U 2002 SB is an ENERGY STAR qualified amplifier and energy efficient product that conserves energy and reduces cost. It meets ENERGY STAR qualification requirements with an auto-standby feature which automatically places the amplifier into Standby Mode after 25 minutes of inactivity thereby dramatically reducing power consumption. It quickly returns to full power status in less than 100 ms upon signal detection, with minimal inrush current. Auto-standby can be disabled if required.

• Single and dual rack-mount hardware included — The included single and side-by-

side rack-mount hardware simplifies planning and saves cost.

• Integrated DSP — The NetPA U 2002 SB has a 6x6 mix matrix which provides

essential DSP processing including level control, filters, dynamics, ducking, and delay.

• Convection cooled, fanless operation - can be stacked without extra rack

space for ventilation — The NetPA U 2002 SB does not require internal fans or vents for cooling, ensuring quiet and reliable operation. It generates substantially less heat than conventional power amplifiers, making it ideal for rack-mount applications where space is limited (see Rack Mounting Ventilation Recommendations on page7).

• Extron Patented CDRS - Class D Ripple Suppression — CDRS is an Extron

Patented technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high frequency switching ripple that is characteristic of Class D amplifiers, a source of RF emissions which can interfere with sensitive AV equipment such as wireless microphones.

• Remote control and monitoring —

• Control and monitor the NetPA U 2002 SB amplifier directly through the RS-232

port.

• Control the NetPA U 2002 SB amplifier through a DMP Plus or XMP processor over

a Dante network.

The NetPA U 2002 SB meets UL 2043 for smoke and heat release for installation within a plenum airspace above a drop ceiling when used with the optional Flexible Conduit Adapter Kit. Above-the-ceiling placement conceals the amplifier to prevent theft, and is convenient for installing equipment when space inside the room is limited.

• Professional grade signal-to-noise and THD+N performance — The NetPA U

2002 SB delivers professional grade performance, featuring 100 dB signal-to-noise ratio and THD+N of less than 0.1%.

• Ultra low inrush current at power up - no need for power sequencing —

Allows multiple NetPA U 2002 SB amplifiers to be powered on simultaneously without overloading power circuits. This eliminates the need for power sequencing.

• Power factor correction - removes harmonic content on AC line — The NetPA

U 2002 SB features power factor correction technology that smooths out the high peak currents of the amplifier’s current draw thereby minimizing the presence of high frequency harmonics on the AC power line and preventing audible artifacts from being transmitted to other audio equipment in the system.

• Automatic clip limiter — Detects actual onset of clipping. Gain is automatically

reduced without audible artifacts to protect speakers from clipping distortion.

• Multiple protection circuits — Activate during output shorts, thermal overload, or DC

faults to prevent damage to the amplifier and speakers.

NetPA U 2002 SB User Guide • Introduction 2

• Remote standby port — Enables the NetPA U 2002 SB to be remotely powered

down when not in use, reducing operating cost.

Installation

This section describes the installation and setup of the NetPA U 2002 SB power amplifier. Topics include:

• Mounting the NetPA U 2002 SB Amplifier

• Rack Mounting

• Flexible Conduit Adapter Kit Installation

Mounting the NetPA U 2002 SB Amplifier

The NetPA U 2002 SB amplifier can be mounted in a rack using the included rack ears, mounted on a rack shelf, set on a table or mounted in the plenum space above a ceiling-mounted projector. Also, two amplifiers can be connected using the bridging plate to create a full rack-width unit.

Tabletop Use

Four self-adhesive rubber feet are included. Attach one foot at each corner on the bottom side of the amplifier and place the unit in a desired location.

UL Rack Mounting Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the equipment in a rack.

• 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, install the equipment in an environment compatible with the maximum ambient temperature (TMA = +32° F to +122° F (0° C to +50° C)/ 10% to 90%, noncondensing) specified by Extron.

• Reduced air flow — Install the equipment in a rack so the amount of air flow required

for safe operation of the equipment is not compromised.

• Mechanical loading — When mounting the equipment in the rack, ensure uneven

mechanical loading does not cause a hazardous condition.

• Circuit overloading — When connecting the equipment to the supply circuit, consider

the effect circuit overloading might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings when addressing this concern.

• Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted

equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, using power strips).

Speaker Outputs — (see figure16 on page17) Connect one 4-pin, 5 mm captive

screw connector for up to two channels of speaker output. Each port has a screw ﬂange to secure the plug to the connector. Observe the correct polarities for each channel as shown below.

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 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 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.

To wire the speaker output, do the following:

Each port has a screw flange to secure the plug to the connector. Follow the instructions below to configure 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 flange 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

NetPA U 2002 SB User Guide • Operation 21

AT Port

The NetPA U 2002 SB supports 2 AT inputs and 2 AT outputs (these are not shared with the analog line outputs). Audio coming in from the mic/line inputs can be placed onto the Dante network, and the AT outputs can be received by any other device as long as it’s using the Dante protocol. The port supports bi-directional channels of 24 bit/48 kHz digital audio.

NOTE: The AT port can be set to 44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz, however the

signal going through the DSP is converted to and processed at 48 kHz.

The AT port allows latency to be set per device at 1.0 ms, 2.0 ms, or 5.0 ms.

Dante Controller provides control and configuration to the entries listed below. However, Dante Controller is not limited to the entries.

• Dante channel routing

• Dante channel naming

• Dante reboot

• Device naming

• Setting network master clock

• Get network and device Dante status

• Set DHCP mode and device IP address

NOTE: For applications where the line and Dante outputs may be used independently during long

periods of no ampliﬁer activity, such as when the unit is being used as both an ampliﬁer and off/ on-ramp to the Dante network, the auto-standby timer must be disabled and the amp must not be forced into Standby mode.

• Setting sample rate to one of the

following frequencies:

• 44.1 kHz

• 48 kHz

• 88.2 kHz

• 96 kHz

Standby Modes

The amplifier may be placed into 3 standby modes through SIS, DSP Configurator or a control system. The unit may also be forced into standby through the rear panel contact closure.

To change the Standby settings via DSP Configurator:

Navigate to the Tools menu and select Configure Standby Settings, then make your selection to change the settings.

Standby Modes

• Disable Auto-Standby Timer = Mode 0

• Enable Auto-Standby Timer = Mode 1

• Force Standby Mode = Mode 2

NetPA U 2002 SB User Guide • Operation 22

Figure 21. Conﬁguring Standby Settings

See the SIS command, Standby on page93 for the commands to send to the amplifier.

Standby Selection (via SIS or Control System):

Mode 0: When the amplifier is in Standby Mode 0, the Auto-Standby Timer is disabled and the amplifier does NOT automatically enter standby mode when no active signal is present on any amp channel for 25 minutes.

Mode 1: When the amplifier is in Standby Mode 1 (default), the Auto-Standby Timer is enabled. The amplifier remains active while there is an active signal on any amp channel. The amplifier enters standby mode if no active signal is present on any amp channel for 25 minutes. It returns to active upon detection of signal on any amp channel. When the SIS command is sent, the timer resets and the amplifier goes into power save state 1.

Mode 2: When the amplifier is forced into Standby Mode 2 via SIS, DSP Configurator, or a control system, the unit remains in standby until the amplifier is placed into Standby Mode 0 or 1 the same way, regardless of signal presence.

Mode 3 (not accessible via DSP Configurator or SIS): This mode occurs when the amplifier begins in Mode 1 and there is no active signal present on any amp channel for 25 minutes. In this mode the amplifier is in standby and can be taken out of standby via an active signal on any amp channel, DSP Configurator, or SIS.

Mode 4 (not accessible via DSP Configurator or SIS): When the amplifier is forced into standby via the STANDBY port (contact closure), it remains in this state until the contact is opened. Once opened, the amplifier returns to its last known standby state. This function overrides all other standby conditions.

NOTE:

• In Standby mode, the line and Dante outputs are muted.

• It is important to note that the auto-standby function relies on active signals that

are routed to the amplified outputs. Signals that are routed only to the line or Dante outputs, but not the amplifier outputs, do not prevent the unit from going into auto-standby due to inactivity.

• For applications where the line and Dante outputs may be used independently

during long periods of no amplifier activity, such as when the unit is being used as both an amplifier and off/on-ramp to the Dante network, the auto-standby timer must be disabled, and the amplifier must not be forced into Standby mode.

Balancing NetPA Amplifier Output Level and XPA Input Sensitivity

Setting proper gain structure is necessary to ensure maximum audio clarity and amplifier output performance. To properly balance the input sensitivity of XPA amplifiers, when used in conjunction with NetPA Ultra Series amplifiers, follow the steps outlined below.

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

The following is an example of how to adjust the NetPA U 2002 SB internal amplifiers to match an external XPA amplifier connected to the NetPA U 2002 SB line outputs:

1. Ensure the NetPA U 2002 SB outputs are properly connected to the XPA amplifier

inputs. Refer to the NetPA U 2002 SB User Guide and XPA User Guide found on www.

extron.com for more details on connecting the amplifiers.

2. Set the attenuation potentiometer on the XPA input to -10 dB (12 o’clock

position), as seen in the image to the right.

3. Open DSP Configurator and connect live to the NetPA U 2002 SB.

4. Double-click the Line Output ATT block (highlighted in yellow) to open the attenuator

dialog box, as shown below in figure 55.

Figure 55. Line Outputs Block

5. Set the Line Output attenuator(s) to -7 dB, as shown in figure 56, below. The

attenuation value can be adjusted by either dragging the fader (1), or clicking in the display box (2), and manually entering the desired value.

6. Click OK (3) to apply the change and close the dialog box.

7. Double-click the Amplifier Output ATT block (highlighted in yellow) to open the

Figure 56. NetPA 2002 SB Line Out Dialog Box

attenuator dialog, as shown in figure57 on the next page.

NetPA U 2002 SB User Guide • DSP Configurator Software 53

Figure 57. Amplifier Outputs Block

8. Set the Amp Out attenuator(s) to 0 dB, as shown in figure 58, below. The attenuation

value can be adjusted by either dragging the fader (1), or clicking in the display box (2), and manually entering the desired value.

Setting the Output Mode

9. Click OK (3) to apply the change and close the dialog box.

The NetPA U 2002 SB output mode is configured via DSP Configurator and the selection is passed to the amplifier board. 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 a output pair behaves

independently. A channel’s level is set by its dedicated attenuator. Input sensitivity in either stereo mode is 0 dBFS.

• 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 output will not be user-controllable in DSP Configurator.

• 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.

NetPA U 2002 SB User Guide • DSP Configurator Software 54

Bridging occurs in the amplifier stage. Channel 1’s positive pin becomes the bridged output’s positive pin, and Channel 2’s positive pin becomes the bridged output’s negative pin.

When the amplifier is set to bridged mono mode, DSP Configurator will delete the Channel 2 amplifier output signal chain, including mix points and output processors.

In the 70V and 100V modes, an 80Hz, 12 dB/octave high-pass filter is applied to the output filter block by default. The user can change this filter. In all other modes, the high-pass filter is not applied by default.

Configuring the Output Mode

1. Select Tools > Configure Amplifier Output Mode to open the Configure

Amplifier Output Mode dialog box.

Figure 59. Configure Amplifier Output Mode Dialog Box

Select the radio button next to the desired output mode. The currently selected mode is indicated with an asterix (*) to the right. The information window to the right of the output mode list displays the DSP and amplifier output settings that will change when the mode settings are applied.

2. Click Apply to apply the amplifier output mode settings to the device. The Confirm

Amplifier Output Mode Selection dialog box will open.

Amplifier Outputs Processing

The amplifier output processing chain in DSP Configurator is represented by a string of blocks as seen in figure 62, below. Each block contains a specific processor or type of processor.

Figure 62. Amplifier Output Processing Chain

The processor chain is as folllows:

• Amplifier Output Trim Block — One trim block is available for each amplifier output

channel. The trim block functions the same as the line/AT output trim block (see Line/

AT Output Trim Block on page50 for information on configuring output filters).

• Amplifier Output Delay Block — One delay block is available for each amplifier

output channel. The delay block functions the same as the line/AT output delay block (see Line/AT Output Delay Block on page51 for information on configuring output filters).

• Amplifier Output Filter Block — One filter block is available for each amplifier output

channel. This filter block functions the same as the line/AT output filter block (see Line/

AT Output Filter Block on page51 for information on configuring output filters).

• Amplifier Output Dynamics Block — One dynamics block is available for each

amplifier output channel. This block functions the same as the line/AT input dynamics block (see Line/AT Output Dynamics Block on page52 for information on configuring the output dynamics block).

• Amplifier Output Attenuation Block — One attenuation block is available for each

amplifier output channel. The attenuation block functions the same as the line/AT output attenuation block (see Line/AT Output Attenuation Block on page52 for information on configuring output filters).

NetPA U 2002 SB User Guide • DSP Configurator Software 56

Monitoring

• High-Pass Filter Information — For bridged mono 70V or 100V output modes, a

fixed high-pass filter is inserted into the output chain of the amplified output. This filter takes up one of the filter slots in the output filter block. This high-pass filter is inserted to prevent the saturation of the transformer cores in the 70V/100V speaker chain by low frequency content. The filter corner frequency and slope can be adjusted. The frequency adjustment has a lower limit of 35 Hz. The filter cannot be deleted, and the filter type cannot be changed.

• Unit temperature — Displays the internal temperature of the amplifier at a

particular location.

• Power Save State — Indicates the standby state that the amplifier is currently in.

• Active (Auto Timer Disabled) — The Auto-Standby Timer is disabled, and

the amplifier does NOT automatically enter standby mode when no active signal is present on any amp channel for 25 minutes.

• Active (Auto Timer running but not triggered) — The Auto-Standby Timer

is enabled. The amplifier remains active while there is an active signal on any amp channel. The amplifier enters standby mode if no active signal is present on any amp channel for 25 minutes. It returns to active upon detection of signal on any amp channel. When the SIS command is sent, the timer resets.

• Standby (SIS triggered) — When the amplifier is forced into Standby via SIS

through DSP Configurator or a control system, the unit does not wake from standby until the amplifier is placed into Standby Mode 0 or 1 (Active [Auto Timer Disabled] or Active [Auto Timer running but not triggered], respectively) the same way, regardless of signal presence.

• Standby (Timer triggered) — The amplifier has entered standby mode

because no active signal was present on any amp channel for 25 minutes. It returns to active upon detection of signal on any amp channel.

• Standby (Contact Closure triggered) — The amplifier has been forced into

standby via the STANDBY port (contact closure), and remains in this state until the contact is opened. Once opened, the amplifier returns to its last known active standby state. This function overrides all other standby conditions.

NetPA U 2002 SB User Guide • DSP Configurator Software 60

Open Circuit Detect

For high impedance amplifiers, open circuit detect requires that the speaker chain be tapped at a minimum of 32 Watts for 70 V systems and 64 Watts for 100 V systems.

For this detection circuit to function, adequate audio signal must be present at the output channel. The output attenuation meters should be bouncing above -50 dBFS.

If at any point an open circuit is detected (yellow or red status), the system should be inspected.

Loss of AC

Since status flags are reset after a power cycle, the amplifier only reports this fault for the short time it remains active after it loses power. This is generally enough time for it to report loss of power to DSP Configurator before disconnecting. Once power is restored and DSP Configurator reconnects, the indicator is gray.

In the event that this status is yellow while DSP Configurator is connected to the amplifier, this represents a short disruption in power.

Dante Controller

This section describes the NetPA Ultra Series network installation, configuration, and control using Dante Controller for Windows and covers the following topics:

• Overview

• Downloading and Installing Dante Controller

• Configuring a NetPA U 2002 SB Amplifier in Dante Controller

• Dante Controller Operation

• Routing Devices

• Dante Troubleshooting

Overview

NetPA Ultra Series ampliﬁers use Dante technology by Audinate to provide high performance digital audio networking over standard TCP/IP networks. The Dante Controller software application is used to route audio on the network. Dante allows audio channels to be transported across a switched Ethernet data network while meeting the quality requirements of professional audio.

Up to 2 channels can be transmitted from a NetPA U 2002 SB ampliﬁer and up to 2 channels can be received from the Dante network. Audio signals are converted by the amplifier, processed and routed to the Line/AT Outputs, and transmitted onto the Dante network. Audinate recommends the Dante audio network be kept separate from other networks. However, 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 U 2002 SB amplifier is a receiver and transmitter for audio signals on a Dante Network. This is possible via a unit AT port. The amplifier can be found anywhere on the Ethernet network and can be relocated without reconfiguring the unit or the network. Dante Controller can configure (but is not limited to) Dante channel routing and naming, device naming, obtaining network and device status, and setting the device IP address.

NOTES:

• The AT port can be set to 44.1 kHz, 48 kHz, 88.2 kHz or 96 kHz, however the

signal going through the DSP is converted to and processed at 48 kHz.

• For applications where the line and Dante outputs may be used independently

during long periods of no amplifier activity, such as when the unit is being used as both an amplifier and off/on-ramp to the Dante network, the auto-standby timer must be disabled and the amplifier must not be forced into Standby mode.

NetPA U 2002 SB User Guide • Dante Controller 75

Downloading and Installing Dante Controller

Device Name

Multiple devices on the same Dante network can present difficulty in identifying individual devices. To avoid confusion and difficulty, ensure the following steps are taken:

• Connect devices to the Dante network one at a time.

• Rename each device before making audio connections in Dante Controller.

• Rename each device with a unique and meaningful identifier.

• Rename each device before the next device is connected to the Dante network.

ATTENTION: It is essential that a Dante device be named before audio subscriptions

with other devices are established. Existing subscriptions are removed when a device is renamed.

ATTENTION : Il est essentiel qu'un appareil Dante soit nommé avant l'établissement

des abonnements audio avec d'autres appareils. Les abonnements existants sont supprimés lorsqu'un appareil est renommé.

In Dante Controller, a device can be renamed to identify the device on the audio network. The default device name of the NetPA Ultra Series consists of the model name, followed by the last six characters of the Dante interface MAC address (for example, NetPA-U-xxxxxx). In addition to renaming the device, individual Transmitter (Tx) and Receiver (Rx) channels can be renamed.

The Dante device name must be set before making any connections to other devices on the Dante network. Renaming a device after making connections removes existing connections to and from that device. Refer to Renaming the NetPA U 2002 SB Amplifier in Dante

Controller on page77 for renaming procedure.

NetPA U 2002 SB User Guide • Dante Controller 76

Receiver and Transmitter Names

In addition to renaming a device, individual transmitter and receiver channels can be renamed in Dante Controller. Rename transmitter and receiver channels to reflect the location of the device or the purpose of the transmitter or receiver. Ensure transmitter and receiver channels are renamed before making audio connections between devices. Refer to

Renaming a Receiver or Transmitter on page79 for renaming procedure.

Dante Controller Naming Conventions

• Device names follow Domain Name System (DNS) hostname rules. Legal characters are

A-Z, a-z, 0-9, and hyphen (-). Names must begin with a letter and cannot end with a hyphen (-).

• Dante Tx and Rx channel names (also known as labels) can be up to 31 characters

in length. Label names are not case-sensitive. For example, “ANALOG OUT-1” and “analog out-1” are recognized as the same name. 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.

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 2002 SB, the line outputs are independent of Dante outputs. Each output may be routed independently. The NetPA U 2002 SB has two Dante outputs.

The NetPA U 2002 SB 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 2002 SB has two Dante inputs.

Dante Routing Operation

Routing Devices

Dante Controller is used for all network signal routing of transmitters and receivers for Dante-enabled devices. The NetPA U 2002 SB transmitters and receivers are available in Dante Controller for routing to other Dante devices.

After the NetPA U 2002 SB amplifier is configured, the channels can be routed to the other Dante devices on the audio network. Channels transmitted to the network or received from the network are routed using the Dante Controller Routing tab on the Network View page (see figure89 on the next page). 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 a transmitter-to-reciever connection, click once on an intersection.

• To remove a connection, click on 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):

NetPA U 2002 SB User Guide • Dante Controller 81

Icon Description

Indicates an active subscription.

Indicates subscription is in progress.

Indicates a pending subscription.

Indicates a broken subscription.

Indicates the transmitting device has been removed from the network or is switched off.

See the Dante Controller User Guide, available at www.audinate.com, for additional information.

Creating Subscriptions Between Devices

1. Ensure the control computer and NetPA Ultra amplifier are connected to the same

network.

2. From the start menu select:

All Programs > Audinate > Dante Controller > Dante Controller

The Dante Controller - Network View screen opens.

Dante Controller auto-discovers Dante devices on the network and advertises itself to allow other Dante-enabled devices to communicate with it. Transmitters connect to receivers using the subscription matrix.

Figure 89. Routing Tab of Network View Screen

3. 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 device expands.

4. To show the receivers of a Dante device, click the + box next to the desired device in

the Dante Receivers panel, such as NetPA-U-MainRack (2).

5. Click the intersection of the desired subscription between a transmitter and a

receiver (3).

NetPA U 2002 SB User Guide • Dante Controller 82

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 connect to only one transmitter. A transmitter can connect to

multiple receivers.

Disconnecting Inputs from Outputs

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.

Dante Troubleshooting

The most common Dante troubleshooting issues occur when devices are not discovered by Dante Controller or when routing is not successful. 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 reseat the Ethernet cable connecting the PC to the Dante network and restart Dante Controller. This can be enough for the software to reacquire the Dante network.

If the problem persists, perform the following troubleshooting procedures in the order listed.

Simplifying the Network for Troubleshooting

If further troubleshooting of Dante Controller is necessary, begin by simplifying the network:

1. Bypass network switches by connecting two Dante-compatible units, such as a

DMP 128 Plus AT and a NetPA U 2002 SB, via their AT ports.

2. Connect the PC to an unused AT port with an Ethernet cable.

3. Use Dante Controller to check if the issue was resolved before moving on to network

interface troubleshooting.

4. 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, continue to diagnose the PC network connections as described below. Check Dante Controller after each step to see if the problem is resolved.

1. Click the Choose a Dante Interface icon (see figure 90, 1). The Configure Dante

Interfaces dialog box opens.

Figure 90. Choose a Dante Interface Icon

NetPA U 2002 SB User Guide • Dante Controller 83

Be certain the correct LAN connection is selected (the PC LAN port that is physically connected to the AT network) and note the IP address.

Figure 91. 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 the Configure Dante Interfaces dialog).

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.

NOTE: A DHCP server must be on the network for DHCP to function correctly.

Restarting Dante Controller

If subscriptions or normal operation cannot be restored, restart Dante Controller software. To access the Dante Controller Help File, do any of the following:

• Click the Help icon in the upper-right corner of the Network View screen (see figure

115).

• Select Help, then Online Help or Offline Help from the menu.

The NetPA U 2002 SB has a serial port that can be connected to a host device such as a computer running either the DataViewer or HyperTerminal utilities. The port makes serial control of the NetPA Ultra Series possible.

TheNetPA U 2002 SB amplifier uses the following baud rate and protocols:

• 38400 baud • 1 stop bit • 8 data bits • No parity

NOTES:

• The rear panel configuration port requires 38400 baud communication. This

speed is higher than most other Extron products. The NetPA Ultra Series control software automatically sets the connection for the appropriate speed. When using DataViewer or similar application, make sure the host PC or control system is set for 38400 baud.

• See Rear Panel Features on page17 for additional details on connecting to

the RS-232 port.

AT Port

The NetPA U 2002 SB amplifier can be connected to a Dante network. SIS Commands can be sent to Dante audio interface devices through a DMP Plus device. To learn how to do this, visit www.extron.com and read any of the user guides from the DMP Plus series of matrix processors, such as the DMP 128 Plus.

The NetPA Ultra Series amplifier Dante port defaults are as follows:

• DHCP: ON

The Ethernet cable can be terminated as a straight-through cable or a crossover cable and must be properly terminated for your application.

• Crossover cable — Direct connection between the computer and the NetPA Ultra

Series amplifier.

• Straight-through (Patch) cable — Connection of the NetPA Ultra Series amplifier to

an Ethernet LAN.

USB Config Port

The NetPA Ultra Series has a rear panel USB port that can be connected to a computer as a host device running the DataViewer utility for control of the device. Once a connection is established, SIS programming can begin (see Host-to-Device Communications below).

Verbose Modes

To receive change notices, the session must be in verbose mode 1 or 3 (see Set verbose

mode on page91). In verbose mode 1 or 3, the unit reports changes in messages that

resemble SIS command responses.

Tagged and Untagged Responses

When a query command is sent in verbose mode 0 or 1, only the “untagged” value is returned. When a query command is sent in other verbose modes, the response is “tagged” and resembles the response to a set command.

Examle: The gain query command EG40000AU} is sent. The following responses appear depending on the verbose mode:

• Untagged (verbose 0 or 1): 600], just the gain value with no other information.

• Tagged (verbose 2 or 3): DsG40000*600], the type of query sent, the OID queried,

NOTE: All query responses listed in this guide are untagged.

and the gain value.

Host-to-Device Communications

NetPA U 2002 SB-initiated Messages

The NetPA U 2002 SB initiates messages under specific conditions. No response is required for the host. The NetPA U 2002 SB-initiated messages are listed below.

The NetPA U 2002 SB initiates the following copyright message when it is first powered on or when a USB connection to the NetPA Ultra is made for the first time since the amplifier powered up.

• Vn.nn is the firmware version number.

• {model} is the full model name, NetPA U 2002 SB, for example.

• 60-nnnn-nn is the NetPA Ultra Series amplifier part number.

The NetPA U 2002 SB amplifier sends the boot and copyright messages under the following circumstances:

• If the NetPA U 2002 SB is off and RS-232 connection is already set up (the source

PC is cabled to the NetPA Ultra Series and a serial communication program such as DataViewer is open), the connected unit sends these messages via RS-232 when first powered on.

Using the Command and Response Tables

•

Space

ASCII to HEX Conversion Table

SIS commands consist of a string (one or more characters per command field). No special characters are required to begin or end a command sequence. When a NetPA U amplifier determines a command is valid, it executes the command and sends a response to the host device. All responses end with a carriage return and a line feed, signaling the end of the response character string.

When programming, certain characters are more conveniently represented by their hexadecimal rather than ASCII values. The table below shows the hexadecimal equivalent of each ASCII character:

The Command and Response tables list valid ASCII commands, the NetPA Ultra Series responses to the host, and descriptions of the command functions with the results of executing the commands.

Error Responses

When the NetPA U 2002 SB is unable to execute the command, it returns an error response to the host. The error response codes and their descriptions are as follows:

E10— Unrecognized command E18— System/command timed out E12— Invalid port number E25— Busy E13— Invalid parameter E25— Device not present E14— Not valid for this configuration E30— Hardware Failure (followed by colon E17— Invalid command for signal type

• Clear all Dante channel audio routing

• Set the Dante device name and channel names to default

times (once at 3 sec., again at 6 sec., again at 9 sec.,), then release and within 1 second press Reset momentarily (<1 sec.).

Mode 5 performs a complete reset to factory defaults, except for firmware:

• Mix-points are set to unity gain (0 dBFS)

• AT input 1 is routed to amp output 1 • AT input 1 is routed to line output 1

• AT input 2 is routed to amp output 2 • AT input 2 is routed to line output 2

• Amp outputs are unmuted and set to -24 dB

• Line and AT outputs are unmuted and set to unity gain

• Trim blocks will be set to unity gain.

• Gain blocks will be unmuted and set to unity gain

• Any inserted or active DSP is removed

• All line inputs are set to unity gain and are unmuted

• All preset and group master memory is cleared

• Status monitoring unsolicited repsonses will be turned off

• Standby timer will be enabled

• Unit will not be in standby
