HiFonics ZXR400/2

The HiFonics ZXR400/2 from the ZEUS POWER series combines powerful amplifier performance with modern Class D technology and exceptionally compact dimensions. For decades, the time-honored ZEUS series has been synonymous with high-performance car audio amplifiers featuring premium build quality and outstanding sound characteristics.

With the ZXR series, HiFonics relies on advanced digital amplifier technology that enables an efficiency of over 90%. As a result, the ZXR400/2 offers high output power with comparatively low power consumption and a space-saving design.

The 2-channel amplifier delivers up to 2 x 200 watts RMS into 2 ohms or 1 x 400 watts RMS in bridged mode into 4 ohms. This makes it 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), an automatic power-on function, and start-stop compatibility. The EMC-certified IFT technology ensures low-interference operation.

High-quality cast aluminum side panels, the blue-illuminated HiFonics logo, and a wired bass-level remote control round out the features.
