HiFonics ZXT8000/1

The HiFonics ZEUS EXTREME ZXT8000/1 is a high-performance digital monoblock amplifier designed specifically for demanding car audio applications and high-power subwoofer systems. As part of the ZEUS EXTREME ULTRA CLASS D series, it combines enormous output power with high efficiency and state-of-the-art amplifier technology.

With an RMS output power of up to 8,000 watts into 1 ohm, the ZXT8000/1 offers impressive power reserves for high-performance bass systems. The advanced Ultra Class D circuitry achieves an efficiency of up to 93%, enabling efficient energy conversion while reducing heat generation.

The amplifier also impresses visually with a high-quality aluminum heat sink, a milled model designation, elegant diamond-cut emblems, and solid aluminum end caps featuring the HiFonics logo.

For precise adaptation to different subwoofer configurations, the ZXT8000/1 features a variable subsonic filter, an adjustable low-pass filter, and an adjustable bass boost. A built-in clipping indicator helps ensure the amplifier is set correctly and aids in detecting signal clipping early on.

Heavy-duty, sealed power and speaker terminals, screw-type RCA jacks, and a triple protection circuit round out the features of this high-performance mono amplifier.
