GZHA MINI ONE-K

The Ground Zero GZHA MINI ONE-K is a compact and powerful mono amplifier from the HYDROGEN series, designed specifically to drive high-performance subwoofers. Despite its relatively compact design, this Class-D amplifier delivers up to 1,000 watts RMS into 1 ohm, making it ideal for high-performance car audio subwoofer systems.

The efficient Class D circuit enables high output power in a compact design. A regulated power supply and generously sized connectors ensure a reliable power supply. By using modern SMD components, Ground Zero was able to house the electronics in the solid heat sink in a space-saving manner.

The GZHA MINI ONE-K offers extensive adjustment options for precise subwoofer tuning. Low-pass and subsonic filters allow you to adjust the desired frequency range, while the adjustable bass boost provides additional headroom in the low-bass range. Phase adjustment allows the subwoofer to be better matched to the rest of the sound system.

The built-in high-level input with automatic power-on function is particularly convenient for integration into various vehicles. This allows the power amplifier to be used with many factory-installed radios or OEM systems that do not have a standard RCA preamp output.

For high-power systems, the amplifier also features a Link Mode. This allows two GZHA MINI ONE-K units to be connected together to provide a significantly higher output power. A wired bass-level remote control for conveniently adjusting the subwoofer level from the driver’s seat is included with the unit.
