In the complicated landscape of audio, many companies put stratospheric price tags on great performance. Our mission couldn't be more different. Simply put, we offer the most performance for the money by finding the sweetest spot between price and diminishing returns. We've all been on the consumer side: music lovers, musicians, and audio enthusiasts looking for top-tier sound without breaking the bank.
Everything we do at Parasound is customer-centric because that's how we define value. Most of our customers don't have trust funds and have to work for their money — so we give them their money's worth and then some. Every time another expert compares our product to equipment that costs three times as much, we have succeeded.

Our Customer Love Us

The Parasound ZoneMaster ZM2350, is a powerful and affordable 350-watt per channel Class D stereo power amplifier with built-in subwoofer crossover, perfect for custom installation and premium audio applications.

The two-channel ZoneMaster ZM2350 draws on the company's renowned heritage of low-noise class AB input stages and analogue bass management, combined with the highest quality Class D amplification to drive 8-ohm speakers to 350 watts per channel and up to 600 watts into 4-ohms.  As with all Parasound amplifiers, the 2350's high current design and extensive heat-sinking enable it to easily drive 2-ohm loads in demanding applications.

In addition to providing high power and audiophile-grade sound quality to stereo speakers, the ZoneMaster 2350 includes installer-friendly features that have proven very popular on Parasound's other ZoneMaster amplifiers. These include a two-channel analogue 80Hz, 24dB/octave low-pass crossover for driving up to four 8-ohm passive subwoofers with 300 watts per sub, without the need for external crossovers. A mono mode permits use of up to eight 8-ohm full-range mono speakers, perfect for applications where stereo sound is not required, such as bars and restaurants.

Each channel features a separate level control, useful to limit the output when using speakers with in-wall volume controls, for left/right balance adjustment to compensate for room placement or to restrict the maximum level in a particular zone. A and B speaker switches, a stereo/mono switch and a switchable 30Hz/80Hz high-pass filter, to improve performance with small speakers, provide flexibility of set up. Both line level and speaker level inputs are catered for, with the option to daisy chain both at line level to another amplifier. The 2350 also features a mono full range line level output and an 80Hz low pass line level output for use with an active subwoofer. Audio-sensing or 12 Volt trigger auto turn-on options complete the line-up of installer friendly features.

"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," said Richard Schram, the company's president and founder. "It has the high horsepower our industry has come to expect from good Class D, and by marrying it with our industry-leading analogue input stage and unique connectivity options, we've created a remarkably rugged, maximum-fidelity amp that can play at the red-line all day. With bass management and versatile installation features, it is also a really practical choice for commercial systems."

So if you are looking for a ultra-flexible but seriously great sounding single zone powerful amplifier (and looking at better subwoofer integration), and one that can be used for a multitude of high performance custom installation situations, then you cannot look any further than the new Parasound ZM2350 - it is a must for any serious custom installation professional and project.
