GZHA MINI ONE-K 24V

The Ground Zero GZHA MINI ONE-K 24V is a compact and powerful mono amplifier from the HYDROGEN series, designed specifically for vehicles with a 24-volt electrical system. This makes the power amplifier particularly well-suited for use in trucks, commercial vehicles, and other 24-volt audio systems.

Despite its compact dimensions, the monoblock delivers an RMS power output of up to 1,000 watts into 1 ohm. The efficient Class D circuitry enables high output power while requiring relatively little space. Adjustable high-pass and low-pass filters, as well as a bass boost, are available for flexible tuning of the connected subwoofer.

Thanks to the built-in high-level input with auto-on function, the power amplifier can also be integrated into audio systems that do not have a standard RCA preamp output. RCA connectors are also available. A wired bass-level remote control is included and allows for convenient adjustment of the subwoofer level from the driver’s seat.

For installations requiring particularly high power output, the GZHA MINI ONE-K 24V also supports Link Mode. In this mode, two amplifiers can be combined to deliver up to 2,000 watts RMS into 2 ohms.
