Parasound ZoneMaster ZM12 12-channel Class AB/D Amplifier

Description

Parasound 12-Zone Audio Power-Compact, Precise, and Ready

The ZM12 packs twelve channels of powerful amplification into a compact 2U rack unit-perfect for delivering music or voice across multiple rooms without taking up space. It combines robust power with flexibility, making it ideal for home or commercial multi-room sound systems.

The ZM12 powers 12 channels across 6 zones, with Zone 1 at 120 W/ch into 8 Ω (150 W into 4/2 Ω) and Zones 2-6 at 60/100 W. A Class‑AB input stage feeds premium Class‑D modules that are stable at 2 Ω, while A/B speaker outputs per channel (24 total) and stereo/mono per‑zone switching simplify real‑world wiring. Integration is painless with per‑zone audio‑sensing and 12 V triggers plus a speaker‑level input for systems without pre‑outs.

Key Features

The Parasound ZoneMaster series offers flexible multi-zone amplification, with models varying mainly in chassis size and channel count to suit different installation requirements. Designed for applications requiring 60 to 150 watts, it features higher power output on Zone 1 (Channels 1 and 2) for more demanding speaker loads. The amplifier provides 24 speaker connections through A and B outputs for all 12 channels, with high-current capability for stable operation at 2 ohms. Its Class AB input stage and premium Class D power stage combine with independent audio-sensing triggers, six individual 12V trigger inputs, looping 12V trigger outputs for each zone, and a master 12V trigger input for coordinated power control.

A speaker-level input supports system expansion without preamplifier outputs, while two bus inputs can be routed to any zone and bus loop outputs allow audio to be passed to another amplifier. Summed Mono mode combines left and right signals for single-speaker applications, and separate level controls are provided for all 12 channels. Detachable speaker connectors accept up to 12-gauge wire, while short-circuit and overheat protection with front-panel indicators help safeguard operation. With standby power consumption of just 0.5 watts, meeting the stated Energy Star and EU specifications, the amplifier is housed in a compact 2U chassis and includes rack-mounting hardware. For installations requiring fewer channels, the ZoneMaster ZM2 and ZM4 are alternative options.
