Parasound's versatile new ZoneMaster 2350 ($1,295 MSRP) is a two-channel Class D amplifier with a Subwoofer mode, allowing the system to drive multiple in-wall subs without the need for an external crossover.

Rated at 350 watts-per-channel into 8 Ohms (600 at 4 Ohms), the amp draws on Parasound's legacy of Class A/B designs, including high-resolution analog input stages and bass management.

"While this is probably my 38th new power amplifier introduction, I am especially excited about the ZoneMaster 2350 as something new and different for Parasound," notes Richard Schram, founder and president, Parasound Products, Inc.

"It has the high horsepower our industry has come to expect from good Class D," he adds, "and by marrying it with our industry leading analog input stage and unique connectivity options, we've created a remarkably rugged, maximum fidelity amp that can play at the redline all day. With bass management and versatile installation features, it is also a really practical choice for commercial systems."

Beyond the 2350's traditional audio performance, the amplifier includes a full selection of installer-friendly features, including separate line-level inputs, speaker-level inputs, A&B speakers, mono/stereo mode switch, 30Hz/80Hz high-pass filter for use with small speakers, stereo loop outputs, and a dedicated mono line output.

A two-channel analog 80Hz, 24dB/octave low-pass crossover enables the amp to drive one or more in-wall passive subwoofers without the need to add a separate crossover or other provisions.

Integrators can incorporate the ZoneMaster 2350 into their preferred control systems via audio-sensing or 12-volt triggers to fully complement whole-house A/V system installations.
