Parasound ZoneMaster ZM2350 2-Channel Power Amplifier

Parasound’s ZoneMaster 2350 two-channel 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.

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. 350 watts x 2 @ 8 Ω, 600 watts x 2 @ 4 Ω, 2 Ω stable for driving multiple speaker pairs, Two pairs of speaker outputs with A/B buttons, Lockout switch on rear panel to disable A/B buttons, High pass filter, switchable for 30Hz or 80Hz, Automatic on/off by 12V trigger w/ looping output, Automatic on/off by audio signal, Speaker level input enables integration with systems lacking preamp output jacks, Parasound designed class AB input stage w/ premium Class D power stage, Subwoofer mode for driving multiple in-wall subs without the need for an external crossover, Mono mode combines L and R for single speaker applications Mono full range preamp output, Subwoofer 80Hz, 24dB/oct. low pass preamp output, Looping left and right output jacks, Left and right input level controls, Efficient, low heat design, Short circuit and overload protection, 0.5 watt standby power consumption meets EU and EnergyStar requirements, 2U rack mounting hardware is included in box.
