Ground Zero GZHA MINI FOUR Amplifier
4-channel Class D Compact Amplifier
Description
The GZHA MINI FOUR from Ground Zero’s Hydrogen Series delivers serious SQ performance in a compact, efficient package. This 4-channel Class D amplifier is ideal for powering front-stage systems or running a full active setup with crystal-clear dynamics and detail.
With 80W x 4 @ 4Ω, 130W x 4 @ 2Ω, and up to 320W x 2 bridged @ 4Ω, this amp is both flexible and powerful. Built-in variable high-pass, low-pass, and bandpass filters, plus auto turn-on high-level inputs, make it perfect for OEM or aftermarket integration.
Its compact chassis (only 210mm long) makes it easy to install in tight spaces, while robust protection circuits and optional GZTA Bassremote provide reliability and control. Whether you're after daily drive fidelity or system-building versatility, the MINI FOUR is a clean, efficient solution with high-end tone.
