Features

Extron Patented Class D Ripple Steering (CDRS™) technology — 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 characteristic of Class D amplifiers, a source of RF emissions, which can interfere with sensitive A/V equipment such as wireless microphones.

Professional grade signal-to-noise and THD performance — Delivers professional grade performance with 100 dB signal-to-noise ratio and THD of less than 0.1%.

Front and rear panel LED indicators —

zzDisplay limiter/protect status when audio clipping or amplifier malfunction occurs. zz Indicate the presence of input signals.

Audio level adjustment — Potentiometers to adjust the audio level from = (full attenuation) to 0 dB (no attenuation).

IEC power switch — Rear panel IEC rocker power switch.

1U full rack enclosure — The capability to deliver full-sized amplifier power in one half the size of many comparable power amplifiers.

High pass filtering — A high pass filter (XPA 2002-70V, XPA 2002-100V,

XPA 2003C-70V, and XPA 2003C-100V only) toggle switch prevents saturation of speaker input transformers by low frequency signals. Saturation can result in severe distortion of the speaker output signal.

Bridged output mode — The XPA 2004 has a toggle switch to input channels 1 and 3 and output each input as a single bridged output channel at twice the power of a single channel. Input 1 is output over the positive terminals of output channels 1 and 2. Input 3 is output over the positive terminals of output channels 3 and 4.

The XPA 2002 has a toggle switch to input channel 1 and output a single bridged output channel at twice the power using the positive terminals of channels 1 and 2.

Convection cooled, fanless operation — Ensuring quiet reliable operation. All models generate substantially less heat than similar power amplifer designs.

Automatic clip limiter — Detects actual onset of clipping by comparing input and output waveforms. Gain is automatically reduced with a slow attack and fast release to eliminate clipping. This advanced limiter design protects the speakers from clipping distortion and offers superior sonic characteristics compared to limiters that use signal compression.

Rear panel recessed, detented level controls — Provide attenuation of input signals for adjusting audio system gain staging as well as multi-zone applications. They are located on the rear panel to prevent users from tampering with level adjustments.

Remote standby — Standby control that remotely shuts off all amplifier output while power remains active at the amplifier.

Power factor correction — Features power factor correction technology that smoothes out the high peak currents of the current draw of the amplifier, thus minimizing the presence of high frequency harmonics on the AC power line, and therefore preventing audible artifacts from being transmitted to other audio equipment in the system.

Class 2 wiring — The outputs from the amplifiers support Class 2 wiring that meets UL requirements.

ENERGY STAR® qualified — All models are ENERGY STAR qualified amplifiers that conserve energy and reduce costs.

Extron Electronics offers a comprehensive range of professional power amplifiers designed for a variety of audio applications. Among these, the XPA 2003C-70V, XPA 2004, XPA 2002, XPA 2002-70V, and XPA 2002-100V stand out for their versatility and efficiency.

The XPA 2003C-70V is particularly notable for its three-channel design, which enables simultaneous connections to multiple speakers in commercial AV installations. It operates at 70 volts, ensuring that long wiring runs do not degrade audio quality. This model employs Extron's patented Class D technology, effectively minimizing heat generation and allowing for a compact form factor. It also features a high-efficiency thermal management system to ensure optimal performance and reliability.

The XPA 2004, on the other hand, is a four-channel amplifier ideal for larger systems. It is similarly designed using Class D technology, offering remarkable efficiency and lightweight construction. This model is equipped with balanced and unbalanced inputs, making it compatible with a wide range of audio sources. Its robust output allows for driving multiple speakers without sacrificing sound quality, making it a favorite for both corporate and educational environments.

The XPA 2002 is a two-channel amplifier that provides reliable performance with 200 watts per channel. It is perfect for smaller applications where powerful audio output is required without the need for multiple channels. Furthermore, it features integrated protections against overload and thermal issues, ensuring consistent operation.

For projects requiring a 70-volt system, the XPA 2002-70V provides a powerful solution. This model supports long-distance signal distribution while delivering exceptional clarity in audio reproduction. Its versatile configuration options make it easy to integrate into existing systems.

Lastly, the XPA 2002-100V is engineered specifically for high-power applications. It can operate in a 100-volt environment, making it suitable for larger venues such as auditoriums and conference centers. Like its counterparts, it benefits from Extron's advanced thermal management and protection features, providing both reliability and sound quality.

These amplifiers all come with Extron's industry-leading support and a warranty, ensuring peace of mind for professionals in the field. With their advanced technologies, superior performance, and varied configurations, the Extron XPA series amplifiers are excellent choices for any audio-visual integration project.
