ZoneMaster® ZM2350

600W of Clean Power for Subs, Garages & Long Cable Runs Drop the ZM2350 into your system and everything feels effortless—passive subs hit harder, outdoor zones stay clean over long cable runs, and the whole presentation tightens up without bulk or heat. In a rack‑friendly 2U chassis it delivers 350 W x2 into 8 Ω (600 W x2 into 4/2 Ω), adds a Subwoofer Mode with an 80 Hz analog low‑pass for passive subs, a switchable 30/80 Hz high‑pass to protect small speakers, and a speaker‑level input for easy integration when your AVR lacks pre‑outs. Praised by reviewers “The ZoneMaster 2350 amp is the real thing… highly recommended.” — Audio Beatnik, May 2019.  “Impressively, for the specs and the price, the ZoneMaster 2350 is a great performer.” — HiFi Sound Enthusiast.
