HiFonics ZXR800/8DSP

The HiFonics ZEUS ZXR800/8DSP combines an analog 8-channel Class A/B amplifier with a powerful 10-channel digital signal processor. This compact unit offers extensive options for custom sound optimization and is suitable both for building fully active speaker systems and for upgrading existing car audio systems.

A key feature is the flexible use of the integrated 10-channel DSP. While the eight amplifier channels can drive speakers directly, all ten DSP channels can alternatively be used to control external power amplifiers. This allows the ZXR800/8DSP to be used as a standalone signal processor.

The built-in 32-bit dual-core DSP allows for precise adjustment of sound reproduction. Features include ten 31-band parametric equalizers, individually configurable crossovers, time alignment, phase reversal, and a freely adjustable input mixer.

Configuration is performed using the ZEUS DSP Master software for Windows or the corresponding smartphone app. Thanks to Bluetooth 5.0, audio signals can also be transmitted wirelessly. Using the MX-Connect port, the amplifier can be integrated into existing sound systems with compatible vehicle-specific adapter cables.

With its extensive connectivity options, ten RCA signal outputs, and the optional HF-DMC OLED remote control, the ZXR800/8DSP provides a versatile foundation for high-end car audio installations.
