HiFonics ZXR600/2

The HiFonics ZEUS POWER ZXR600/2 combines powerful amplifier output, modern Class D technology, and high-quality craftsmanship in an exceptionally compact enclosure. For decades, the ZEUS series has been synonymous with high-performance car audio amplifiers that deliver excellent sound quality and exceptional reliability.

With the ZXR series, HiFonics has further developed its proven ZEUS technology and relies on efficient digital Class D circuits. These enable an efficiency of over 90% and ensure that, even at high output power levels, comparatively little energy is converted into heat.

The ZXR600/2 delivers up to 2 x 300 watts RMS into 2 ohms or 1 x 600 watts RMS in bridge mode into 4 ohms. This makes the amplifier suitable for both high-power speaker systems and for driving a subwoofer.

For integration into modern vehicles, the amplifier features high-level inputs with EPS® (Error Protection System). These allow connection to factory-installed car stereos and are designed to prevent error messages from the vehicle’s electronics. The automatic power-on function, start-stop compatibility, and IFT technology for reducing electromagnetic interference round out the features.

Other features include high-quality, audiophile-tuned components, cast aluminum side panels, a blue-illuminated HiFonics logo, and a wired bass-level remote control.
