Ground Zero GZPA 2SQ
The Ground Zero GZPA 2SQ is a high-end 2-channel amplifier from the Plutonium collection.
An amplifier designed purely for sound quality with BIAS control. The BIAS control can be used to adjust how long the amplifier operates in pure Class A. With a lower BIAS control, the amplifier works better in controlling treble and midrange. The sound image is more three-dimensional, the tone is warmer and the nuances are more accurate. With a higher control, you get better performance in the bass range. More authority and power. Thanks to the very robust dual power supply, the reproduction is accurate and the sound is powerful.
Mundorf capacitors and Burr&Brown operational amplifiers are guaranteed to be the highest quality parts available for automotive use.
The amplifier is stable up to 1 ohm loads.
