About this Guide

This guide describes the XPA U 1004 SB and XPA U 2002 SB Half Rack Four-Channel/TwoChannel audio power amplifiers and discusses how to install, configure, and operate them.

In this guide, the terms “unit”, “amplifier”, and “power amplifier” refer to the XPA U 1004 SB and XPA U 2002 SB.

About the XPA U 1004 SB and XPA U 2002 SB

The Extron XPA U 1004 SB and XPA U 2002 SB are ENERGY STAR qualified four- and two-channel audio power amplifiers with flexible channel pairs that can drive 8 ohm, 4 ohm, 70volt, or 100 volt loads. The XPA U 1004 SB’s two individually bridgeable pairs can deliver two 100 watt channels into low-impedance systems or one 200 watt channel into low- or high-impedance systems. The XPA U 2002 SB’s bridgeable output pair can deliver two 200 watt channels into low-impedance systems or one 400 watt channel into low- or highimpedance systems.

Output mode selection is made via a rear panel rotary switch for quick and easy setup. The convection-cooled, plenum-rated enclosures of the XPA U 1004 SB and XPA U 2002 SB don’t require empty rack spaces for ventilation and include rack mount hardware. They feature a highly efficient advanced Class D amplifier design with defeatable auto standby, fast wake up from standby, and patented Extron CDRS (Class D Ripple Suppression) technology. Remote volume and mute control is possible per channel pair from Extron VCM, VC, and select MediaLink controllers.

• ENERGY STAR

qualified amplifiers — The XPA U 1004 SB and the XPA U 2002 SB

are ENERGY STAR qualified and energy efficient amplifiers, conserving energy and reducing costs.

• Extron Patented CDRS (Class D Ripple Suppression) Technology — CDRS is an

Extron pantented technology providing a smooth and clean audio waveform, and improving signal fidelity over Class D amplifier designs.

• CDRS eliminates the high frequency switching ripple characteristics of Class D

amplifiers, a source of RF emissions which can interfere with sensitive AV equipment like wireless mircophones.

• Convection cooled and fanless operation ‑ can be stacked without extra rack space for

• ventilation — The XPA U 1004 SB and the XPA U 2002 SB do not have internal fans or

vents for cooling, ensuring quiet reliable operation. The units generate substantially less heat than conventional power amplifiers, making the XPA Ultra Series ideal for rack-mount applications where space is limited.

• See Rack Mounting Ventilation Recommendations on page7.

• Defeatable auto-standby with fast wake up — The amplifiers meet ENERGY STAR

qualification requirements with an auto-standby feature that automatically places the units into standby after 25 minutes of in activity; thereby dramatically reducing power consumption. The XPA U 1004 SB and XPA U 2002 SB quickly return to full power in less 100 ms upon signal detection, with minimal inrush current. Auto-standby can be disabled if required.

• UL 2043 Plenum rated when used with the optional Flexible Conduit Adapter Kit/

AV equipment — The XPA U 1004 SB and XPA U 2002 SB amplifiers meet UL 2043 when installed with the Flexible Conduit Adapter Kit, part # 70-228-02. The amplifiers must meet this requirement for heat and smoke release for installation within a plenum airspace. Above-the-ceiling placement conceals the amplifier to prevent theft, and it is convenient for installing when space inside the room is limited.

• Remote volume and mute control per channel pair — With Extron VCM, VC, and

select MediaLink controllers.

• All rated watts are usable with all channels driven — With a XPA Ultra, designs can

utilize 100% of the rated power.

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

XPA U 1004 SB and XPA U 2002 SB • Introduction 2

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

multiple XPA Ultra amplifier 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 XPA U

1004 SB and XPA U 2002 SB features power factor correction technology that smooths out the high peak currents of the amplifier’s current draw, minimizing the presence of high frequency harmonics on the AC power line, preventing audible artifacts from being transmitted to other audio equipment in the system.

• Rear panel recessed, detented level controls — Provides attenuation of input signal

for adjusting audio system gain staging. These controls are lcoated on the rear panel to prevent tampering with the level adjustments. Laser etched markings provide enhanced visibility of settings for ease of configuration.

• Remote standby port — Enables the XPA U 1004 SB and XPA U 2002 SB to be

remotely powered down when not in use, reducing operating cost.

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

reduced without audible artifacts to prevent clipping distortion.

Installation

This section describes the installation and setup of the XPA U 1004 SB and XPA U 2002 SB.

Topics include:

• Mounting the XPA Ultra Series Amplifiers

• Flexible Conduit Adapter Kit Installation

Mounting the XPA Ultra Series Amplifiers

The XPA U 1004 SB and XPA U 2002 SB can be mounted in a rack using rack ears,

mounted on a rack shelf, set on a table, or mounted in the plenum space above a ceilingmounted projector. Also, two amplifiers can be connected using the bridging plate to create a full rack-width unit.

This guide uses images of the XPA U 1004 SB to describe installation, but both amplifiers

are installed the same way.

Tabletop Use

Four self-adhesive rubber 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, use of power strips).

Power/Standby LED — A single LED that lights green when the unit is on and active,

and lights amber when:

• The unit is in standby mode, which turns off all outputs from the amplifier although

the amplifier still receives power.

• The unit will not come out of standby when DC voltage is detected. The amplifier

only comes out of standby mode by either resetting the device or powering it down.

NOTE: Power indicator LED may stay lit amber for a short time after removing the AC

Power Supply. This is normal.

Over Temp Indicator — A single LED that lights red when the amplifier has exceeded

the maximum recommended operating temperature. The amplifier recovers once the unit has cooled down to below the maximum recommended operating temperature. Power limiting may occur, but it depends on the unit’s temperature.

Removable IEC Power Receptacle — Connect the supplied IEC power cord here

for power input (100 VAC to 240 VAC, 50-60 Hz) to the internal power supply. The connector can be replaced by a Flexible Conduit Adapter Kit (see Flexible Conduit

Adapter Kit Installation on page8).

Channel Status LEDs — The 1004 SB has four double-stacked LEDs, while the 2002

SB has two double-stacked LEDs. The top red LEDs indicate limiter/protect status, and the bottom green LEDs indicate signal status. These LEDs share the same function as the front panel LEDs.

Attenuators — Use a small screwdriver to adjust the gain structure for a corresponding

channel. Each channel has its own potentiometer, ranging from ∞ (full attenuation) to 0 dB (no attenuation)

To adjust the attenuation level on the amplifier, perform the following:

When volume is controlled at the source:

1. If connecting to a source device with volume control (variable output), ensure the

volume on the source device is set to its lowest point, then adjust the attenuation of the amplifier fully counterclockwise.

XPA U 1004 SB and XPA U 2002 SB • Operation 13

2. Set the source device volume to the maximum level. No sound should come out.

Stereo 8Ω or 4Ω Output Modes

Bridged Mono 8Ω/16Ω/70V/100V Modes

or 100V Speaker Loads

3. Raise the attenuation on the XPA Ultra Series amplifier until sound distortion occurs,

then lower the attenuation level slowly until distortion disappears. This setting ensures no clipping occurs, whatever the source device volume setting is.

NOTE: When setting volume control through a source device, make sure the

device’s volume is set to variable out. Consult the device’s user manual for detailed instructions on its calibration.

When volume is controlled at the amplifier:

1. If volume will be controlled at the amplifier using a remote volume control

(see section G for details), ensure the volume on the source device is set to its lowest point, then adjust the attenuation of the amplifier fully counterclockwise.

2. Set the source device’s volume to its maximum level.

3. Set the remote volume control to its maximum level. No sound should come out.

4. Raise the attenuation on the XPA Ultra Series amplifier until sound distortion occurs,

then lower the attenuation level slowly until distortion disappears. This setting ensures no clipping occurs, whatever the source device volume setting is.

NOTE: When volume will be controlled at the amplifier using a remote volume

control, make sure the source device’s audio output is set to fixed out (local volume control is disabled). Consult the device’s user manual for detailed instructions on its calibration.

channels 3 and 4. There are eight settings that are divided into stereo and bridged mono:

• Stereo Mode (4 ohm/8 ohm) — Each channel of a output pair behaves

independently, and each input is routed to its respective output. A channel’s level is set by its dedicated attenuator.

• Bridged Mono Modes — There are six bridged mono modes: two low-impedance

(8 ohm and 16 ohm bridged) and four high-impedance (70V, 70V with no HPF, 100V, and 100V with no HPF)

In all six mono modes, the outputs of a pair are bridged, and the lowest-numbered channel is fed to the pair’s positive pins. The bridged output’s positive pin is now the lowest-numbered channel’s pin. And the higher-numbered output’s positive pin becomes the bridged output’s negative pin.

The level is set by using the attenuator on the lowest-numbered channel. The higher-numbered channel’s input and attenuator are not used in bridged mono mode.

In either 70V or 100V modes, an 80 Hz, 12 dB/octave high-pass filter is applied to the signal. This can be disabled by selecting (HPF OFF) for either 70V or 100V mode. On 8 ohm and 16 ohm bridged modes, the filter is disabled.

& 2

NOTE: In 70V/100V output modes, HPF should be disabled at the amplifier

only if a high-pass filter will be applied upstream of the amplifier.

Line Input — (see figure 14 on page14) Wire the amplifier input connectors based

on the output. See Figure 16 for details on how to wire the input connectors.

NOTE: In bridged mono output modes, even-numbered channels are not used in

the connector.

Speaker Output Connectors — (see figure 14 on page14)

Connect up to two 4-pin, 5mm captive screw connectors for up to four channels of speaker outputs. Each port has a screw flange to secure the plug to the connector. Observe the correct polarities for each channel as shown to the right.

XPA U 1004 SB and XPA U 2002 SB • Operation 15

WARNING:

Resistor

AVERTISSEMENT :

• 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 (8Ω/4Ω) and high-impedance speaker loads (70V) 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.

NOTE: You must use Class 2 wiring for this output to comply with UL requirements.

To wire the stereo audio output, do the

following steps:

1. Strip and insert the speaker wires into the

connector and tighten the captive screws.

Make sure to observe correct polarity.

Do not tin the wires!

2. Insert the wired connector into the amplifier output,

and secure the plug by tightening the screws on either side..

G Remote Ports — (see figure 14 on page14) On the XPA U 1004 SB, connect a

3-pole, 3.5mm captive screw connector for remote volume control on channels three and four. On both amplifiers, there is a 5-pole captive screw port. The bottom port use a 3-pin captive screw plug for volume control of channels 1 and 2 on the V, C, and G pins, and a 2-pin captive screw for standby on the STANDBY and G pins.

Remote Volume Control Port

Pins V, C, and G (1, 2, and 3) control volume by varying the DC voltage from 0 V (full attenuation) to 10 V (maximum volume) with full muting in effect when pin C is connected to ground (pin G).
