HiFonics ZXS700/4

The HiFonics ZXS700/4 from the ZEUS STREET series combines powerful amplifier technology with exceptionally compact dimensions. While classic ZEUS power amplifiers became known for their solid construction, the ZXS series relies on modern Class D technology, which offers high efficiency and significantly reduced space requirements.

Despite its compact design, the ZXS700/4 delivers an impressive output power of up to 4 × 175 watts RMS at 2 ohms. In bridge mode, it even delivers 2 × 350 watts RMS at 4 ohms. This makes the amplifier suitable for both high-power front and rear speaker systems as well as combined speaker and subwoofer setups.

High-quality, carefully selected components, a robust heat sink housing, and elegant aluminum accents underscore the ZEUS series' commitment to quality.

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 integrated IFT (Interference Free Technology) reduces electromagnetic interference and ensures interference-free radio reception.

Individually adjustable high-pass and low-pass filters for both channel pairs allow for flexible adaptation to different speaker configurations.
