Parasound ZoneMaster Series ZM12 Power Amplifier | 100W x 10 Channels and 150W x 2 Channels

The Parasound ZoneMaster ZM12 is a twelve-channel power amplifier purpose-built for whole-home or multi-zone audio distribution systems. It combines two higher-powered stereo channels — rated at 120W x 2 into 8 ohms — with ten additional zone channels rated at 60W each, all within a compact 3U chassis. This makes the ZM12 a practical centerpiece for residential distributed audio installations managed from a single amplifier.

The ZM12 includes built-in high and low pass crossover filtering, including a dedicated subwoofer mode with an 80 Hz crossover at 24 dB per octave and a selectable high pass filter at 30 Hz or 80 Hz at 12 dB per octave. THD is under 0.05% at typical listening levels. Signal-to-noise ratio exceeds 112 dB A-weighted. Audio and external 12V triggers are both supported, and the unit accepts universal voltage from 100 to 250 VAC. Net weight is 21 lbs.
