GZIA 100.2

The Ground Zero GZIA 100.2 is a compact 2-channel amplifier from the IRIDIUM series and is ideal for providing high-power drive to a front or rear speaker system. Thanks to classic Class A/B technology, this power amplifier combines clean music reproduction with solid output power and extensive adjustment options.

At 4 ohms, the GZIA 100.2 delivers 2 x 75 watts RMS; at 2 ohms, the power increases to 2 x 120 watts RMS. This allows for the operation of numerous car audio speaker systems with sufficient power reserves. Alternatively, the power amplifier can be used in bridge mode, for example, to drive a single speaker or subwoofer.

For flexible audio system tuning, the amplifier features built-in high-pass and low-pass filters. The low-pass filter can be adjusted between 30 and 250 Hz, while the high-pass filter offers a range from 40 Hz to 3 kHz. A bass boost function is also available.

The built-in high-level input with automatic power-on function is particularly convenient for integration into vehicles equipped with factory-installed radios. This means the amplifier can also be used in many OEM audio systems without necessarily requiring a traditional RCA preamp output on the radio.

Measuring just 168 x 49 x 175 mm, the GZIA 100.2 requires relatively little installation space. The black anodized heat sink ensures a robust design and the look typical of Ground Zero.
