Parasound ZoneMaster ZM12
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. Why installers choose it One amp, whole house: 6 independent zones with higher‑power Zone 1 for the main living area. Flexible wiring: A/B outputs per channel (up to 24 speakers) and summed‑mono for single‑speaker areas. Easy automation & retrofits: Per‑zone audio‑sense/12 V triggers, bus inputs/loop‑outs, and a speaker‑level input when there are no pre‑outs. Covered by Parasound's 2-Year Parts & Labor Warranty.
