HiFonics ZXR700/2E

The HiFonics ZXR700/2E from the ZEUS POWER EXPANSION series combines modern Class D technology with high output power and exceptionally compact dimensions. This powerful 2-channel power amplifier uses a high-quality Infineon® chipset and offers high efficiency as well as stable power output down to 1 ohm per channel.

The ZEUS E-Class expands the proven ZXR amplifier series with high-performance digital power amplifiers featuring advanced circuit technology. The series was named “PRODUCT OF THE YEAR 2025” by the trade magazine Car & Hifi in its January 2025 issue.

With up to 2 x 350 watts RMS at 1 ohm or 700 watts RMS in bridged mode at 2 ohms, the ZXR700/2E is suitable for both high-power speaker systems and subwoofer applications.

Its extensive features include adjustable high- and low-pass filters up to 5,000 Hz, a bass boost, RCA inputs and outputs, and high-level inputs with EPS® (Error Protection System). The automatic power-on function allows for integration into existing vehicle systems. A compact bass-level remote control also allows for convenient adjustment of the bass level.

Carefully selected, audiophile-tuned components, die-cast aluminum side panels, and the blue-illuminated HiFonics logo panel highlight the high-quality construction. Thanks to IFT (Interference Free Technology) and start-stop compatibility, the power amplifier is also suitable for modern vehicles.
