GZIA 1000.1

The Ground Zero GZIA 1000.1 is a high-performance mono amplifier from the IRIDIUM series, designed specifically for driving subwoofers. With an RMS power output of up to 1,250 watts into 1 ohm, this compact Class D amplifier provides ample power reserves for powerful and controlled bass reproduction.

A key feature is the GZ-PowerBalance power supply control. It ensures a constant output power even when the supply voltage fluctuates. This makes the GZIA 1000.1 particularly well-suited for high-performance car audio systems that require a reliable power supply for the subwoofer.

An adjustable low-pass filter and a variable subsonic filter are available to adapt to different subwoofers and enclosure designs. In addition, both the frequency and intensity of the bass boost can be adjusted. This allows the bass response to be precisely tailored to the vehicle, subwoofer, and personal listening preferences.

In addition to the standard RCA input, the power amplifier features a high-level input with an automatic power-on function and a dummy load. This allows the amplifier to be integrated into many vehicles equipped with factory-installed radios or OEM sound systems that do not have a conventional RCA preamp output.

The included wired bass-level remote control allows for convenient level adjustment from the driver's seat. Thermal, short-circuit, and overload protection circuits further ensure safe operation.
