HiFonics ZXT1000/1

The HiFonics ZXT1000/1 from the ZEUS EXTREME series is a powerful digital single-channel amplifier that combines modern Ultra Class D technology with high output power and exceptional efficiency. With up to 1,250 watts RMS at 1 ohm, this monoblock is particularly well-suited for demanding car audio and subwoofer systems.

Modern amplifier technology enables an efficiency of up to 94%, thereby reducing energy losses and heat generation. The solid aluminum heat sink, featuring high-quality cast aluminum end caps, ensures reliable heat dissipation and highlights the distinctive look of the ZEUS EXTREME series.

An adjustable subsonic filter, a low-pass filter, and an adjustable bass boost are available for customizing the sound. The extremely high damping factor of over 6,000 allows for precise control of connected subwoofers.

Screw-type RCA connectors, sealed power and speaker terminals, a clipping LED, and a triple protection circuit round out the high-quality features.
