HiFonics ZXS900/6

The HiFonics ZXS900/6 from the ZEUS STREET series combines powerful amplifier technology with an exceptionally compact enclosure. While classic ZEUS amplifiers became known for their imposing dimensions, the ZXS series relies on modern Class D technology, which offers high efficiency and a reduced footprint.

Despite its compact design, the ZXS900/6 offers six powerful amplifier channels that can be flexibly used for a variety of car audio configurations. Whether for an active speaker system, a combination of front and rear speakers, or the addition of a subwoofer—the amplifier offers numerous connection options.

The high-quality components, the sturdy aluminum housing with milled details, and the elegant aluminum end caps underscore the ZEUS series' commitment to quality. Thanks to the efficient Class D circuitry, heat loss is reduced while delivering high output power.

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. HiFonics IFT (Interference Free Technology) minimizes electromagnetic interference and ensures interference-free radio reception.

Individually adjustable high-pass, low-pass, and band-pass filters allow for precise tuning of the connected speakers. The input selector switch allows the amplifier to operate with two, four, or six input channels.
