Powerful Multi‑Zone Sound in a Compact Rack Unit

The ZM4 fits into a mere 1U chassis but packs four full channels—ideal for powering speakers in multiple rooms without taking up space. Whether you’re running backyard speakers, a secondary stereo, or home theater surrounds, it delivers clean, consistent volume that stays smooth even under heavy loads.

In plain terms: 120 W ×4 into 8 Ω (150 W ×4 into 4/2 Ω; 2‑ohm stable), a Class‑AB input stage feeding premium Class‑D outputs, A/B speaker outputs per channel with stereo/mono per‑zone switching, and bus input with loop‑outs plus per‑zone audio‑sensing and 12 V triggers for painless installs.
