GZIA 200.2

The Ground Zero GZIA 200.2 is a high-performance 2-channel amplifier from the IRIDIUM series and is ideal for building a powerful front- or rear-system power amplifier, as well as for bridged operation of a subwoofer. The classic Class A/B circuitry combines dynamic power delivery with clean and controlled music reproduction.

With 2 x 135 watts RMS at 4 ohms, the GZIA 200.2 offers ample power reserves even for standard speaker systems. At an impedance of 2 ohms, the output power increases to up to 2 x 230 watts RMS. For applications with a single high-power speaker or subwoofer, the amplifier can also be operated in bridge mode.

A built-in active crossover allows the amplifier to be adapted to different speaker configurations. High-pass and low-pass filters can be adjusted as needed, so that the frequency range to be reproduced can be precisely tailored to the connected speaker system.

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

A robust power supply, generously sized connectors, and the black anodized aluminum heat sink ensure reliable performance for everyday car audio use. A wired volume remote control is also included.
