Description
Parasound’s ZM2350 two-channel amplifier makes everything in your system feel effortless. Passive subs hit harder, outdoor zones stay clean over long cable runs, and the whole presentation tightens up without bulk or heat. This amplifier is designed from the ground up to be as friendly to custom installations as it is powerful. With 600 watts x 2 available, it will drive any speaker or passive subwoofer with ease. Unique preamp outputs for full-range mono and low-pass mono provide unsurpassed flexibility. A switch engages an analog 30 Hz or 80 Hz high-pass filter to prevent heavy bass from reaching smaller speakers. A built-in analog 80 Hz, 24 dB/octave low-pass filter makes the ZoneMaster 2350 an outstanding amplifier for driving multiple in-wall passive subwoofers without the need for external crossovers. 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.
