Parasound ZoneMaster Series ZM2350 Power Amplifier with Sub Crossover | 600W x 2 Channels

The Parasound ZoneMaster ZM2350 is a two-channel power amplifier with an integrated subwoofer crossover, designed for installations where main speakers and a subwoofer are driven from a single amplifier chassis. Rated at 350W per channel into 8 ohms and 600W per channel into 4 ohms, it provides substantial output for primary listening zones in residential AV systems. The compact 3U chassis measures 17.25 x 3.5 x 14.5 inches.

The ZM2350 incorporates high and low pass crossover filtering tailored for subwoofer integration: a dedicated sub mode with an 80 Hz crossover at 24 dB per octave and a selectable high pass filter at 30 Hz or 80 Hz at 12 dB per octave. THD is under 0.05% at typical levels, and the signal-to-noise ratio exceeds 114 dB A-weighted. Frequency response extends from 10 Hz to 70 kHz. Both audio trigger (2 mV) and external 12V trigger inputs are supported. Net weight is 15 lbs.
