A versatile zone amplifier

The Parasound ZoneMaster 2350 delivers 350 watts per channel, and it offers a wide variety of configuration options for custom installation and multi-zone audio applications. It can drive multiple speakers or subwoofers with ease, thanks to ample power output and a 2-ohm stable design.

Configuration flexibility

This amp features a three-position Output Mode switch that gives you multiple configuration options. In Stereo mode, it can drive A and B speaker pairs, such as in your main room or in a second zone. A built-in impedance switch means you can even use hard-to-drive 4-ohm speakers in this configuration.

In Mono mode, it's 2-ohm stable, which allows it to drive up to 8 speakers at the same time in a large room or outdoor space, all playing the same mono signal. In Sub mode, an 80 Hz low-pass filter is applied, so the amp can drive one or more passive subwoofers. And there's a stereo RCA loop output that lets you daisy chain additional amplifiers.

The amp can start automatically when your system is turned on via a 12-volt trigger, or when it senses an incoming signal. Buttons on the front panel let you engage A/B or A+B speakers, or you can use to rear-panel lockout switch to keep both pairs on at all times.
