Ground Zero has designed the GZ ULTRA A-2 as the ultimate in high-end, no- compromise automotive audio. A two-channel, dual mono Class AB amplifier for the hi-fi enthusiast demanding the very best in sound reproduction, it’s constructed from high-grade components in as minimalistic way as possible – even potentiometers have been replaced by fixed resistors. Premium features include adjustable bias to perfect its sonic output and optional water cooling is offered to keep its temperature optimal. The GZ ULTRA A-2’s sound is so neutral, open and perfectly balanced that the music always shines through. With plenty of power on tap, this is truly an amplifier that deserves the ‘high-end’ label.
