HiFonics ZXR1200/4E

The HiFonics ZXR1200/4E from the ZEUS POWER EXPANSION series combines enormous output power with modern, highly efficient Class D technology and exceptionally compact dimensions. With up to 4 × 300 watts RMS at 2 ohms, this digital 4-channel amplifier offers ample power reserves for demanding car audio systems.

The ZEUS E-Class expands the proven ZXR amplifier series with high-performance digital power amplifiers featuring premium, precision-tuned components. Despite its compact design, the ZXR1200/4E impresses with powerful dynamics, high sound quality, and versatile applications. The amplifier series was named “PRODUCT OF THE YEAR 2025” by the trade magazine Car & HiFi in its January 2025 issue.

Thanks to built-in high-level inputs with EPS® (Error Protection System), an automatic power-on function, and start-stop compatibility, the power amplifier is also suitable for integration into modern vehicles with factory-installed radio systems. The adjustable high-pass and low-pass filters for the front and rear channels allow for flexible adaptation to different speaker configurations.

The design is rounded out by high-quality cast aluminum side panels, IFT technology for reducing electromagnetic interference, and the distinctive blue-illuminated HiFonics logo panel.
