The Extron XPA U 2002 SB is an ENERGY STAR qualified two channel audio power amplifier with a flexible output that can drive 8 ohm, 4 ohm, 70 volt, or 100 volt loads. The bridgeable channels can deliver two 200 watt channels into low impedance systems or a mono 400 watt channel into low or high impedance systems. A rotary switch on the rear panel makes it quick and easy to select output mode. The convection cooled, plenum rated enclosure of the XPA U 2002 SB does not require empty rack spaces for ventilation and includes rack mount hardware. It features a highly efficient advanced Class D amplifier design with defeatable auto standby, fast wake up from standby, and our patented CDRS – Class D Ripple Suppression. XPA Ultra SB models also offer remote volume and mute control with Extron VCM, VC or select MediaLink controllers.
Switchable Bridging
Selectable output modes provide the flexibility to make an XPA U 2002 SB the go-to solution for nearly any application requiring 200 watts to 400 watts per channel. This single power amplifier can handle the requirements of a diverse set of system configurations:
- Two 8/4 ohm 200 watt channels for high performance stereo program playback
- A single bridged 400 watt high impedance channel for high performance 70V/100V systems
Compact Installations
The XPA U 2002 SB doesn't require empty rack spaces for cooling or external transformers, allowing it to be installed in less rack space compared to competitive amplifiers. This is made possible by Extron's advanced thermal engineering, which includes fanless convection cooling, no chassis heatsinks, and Everlast power supplies. The cumulative effect of hundreds of precise design choices enables many XPA U 2002 SB units to be placed in an equipment rack without the need to waste rack space for ventilation above the amplifiers.

Designed by Extron
Every circuit in an XPA® Ultra power amplifier is designed by our team of dedicated power amplifier engineers, ensuring that every Extron amplifier meets our high standards of excellence. By designing everything in-house, Extron engineers can meticulously optimize every detail for maximum performance, reliability, power efficiency, and reduced heat.
High Efficiency
With tested and measured efficiency benchmarks up to 77%, an XPA Ultra amplifier uses less electricity to generate the same amount of power. This has the direct benefit of lower electricity costs and less power infrastructure required.
Cool Operation
An XPA Ultra amplifier runs up to 28% cooler, with up to 49% less power wasted as heat, and up to 59% less radiated heat compared to competitive amplifiers. Electronics that run cooler, last longer and don’t transfer heat to other gear sharing the same rack. The low radiated heat of the XPA Ultra amplifiers, enabled by our advanced thermal engineering, saves on cooling costs and allows more channels of amplification to be put into fewer rack spaces.
InstaWake
The XPA U 2002 SB meets ENERGY STAR qualification requirements with an auto power-down feature that places the amplifier into standby after 25 minutes of inactivity. When in standby, the XPA U 2002 SB draws less than one watt of power. It quickly comes out of standby upon detection of signal in under 100 milliseconds, fast enough that the beginning of audio is not cut off. When coming out of standby, the XPA U 2002 SB draws minimal inrush current, creating no sudden demand on power systems. For applications where the amplifier is required to remain active at all times, an XPA Ultra amplifier provides the ability to defeat auto-standby while maintaining ENERGY STAR status.
Rock-Solid Reliability
Product reliability is a high priority at Extron and we go to great lengths to engineer products with industry-leading low failure rates, driven by rigorous testing of everything we ship. From the elimination of short-lived electrolytic capacitors in the signal path, to PCB designs that exclude the use of failure-prone wire harnesses, to accelerated burn-in testing, the XPA U 2002 SB is engineered by Extron for many years of service.
