The Zamp•Quattro is a four channel, two zone power amplifier. Its unique half rack and compact size makes it incredibly
versatile. Unlike most Class D amplifiers that are based on inexpensive car audio chips, the Zamp•Quattro's Swedish
Class D design uses only high-grade parts. With additional output filtering and class AB input stage the result is a great
sounding amp that is stable with low impedance loads and with reduced heat. Speaker level inputs allow the
Zamp•Quattro to work with any receiver, even those without preamp outputs.
