HiFonics ZXR1200/2E

The ZEUS E-Class expands the proven HiFonics ZXR series with modern, exceptionally powerful, and highly efficient Class-D amplifiers. The models in the EXPANSION series impress with their enormous power reserves, combined with compact dimensions and high-quality craftsmanship.

The HiFonics ZXR1200/2E is one of the most powerful 2-channel amplifiers in this series. Thanks to modern Infineon® chipsets and stable operation down to 1 ohm, the power amplifier delivers an impressive 2 x 600 watts RMS at 1 ohm. In bridged mode, it even delivers up to 1,200 watts RMS at 2 ohms.

In a test conducted by the trade magazine *Car & HiFi* (Issue 1/2025), the ZXR1200/2E significantly exceeded its rated power output. Measurements showed 2 x 807 watts RMS at 1 ohm and 1,614 watts RMS in bridged mode at 2 ohms. For this outstanding performance, the amplifier received the “BEST PRODUCT” award in the top class. The ZEUS EXPANSION series was also named “PRODUCT OF THE YEAR 2025.”

Its extensive features include high-level inputs with EPS® technology, an automatic power-on function, variable high- and low-pass filters, and a compact bass-level remote control. Modern IFT technology ensures improved electromagnetic compatibility and minimizes potential interference in the vehicle.
