Finally there is a whole house distribution amplifier worthy of being called a Parasound. The ZoneMaster will effortlessly power up to twelve speakers using either a stereo signal, a mono signal or twelve independent signals. Along with auto turn on capability and separate volume control for each channel, this could be one of the most flexible mulit-zone amplifiers ever!
