A versatile two-channel amplifier

The Parasound ZoneMaster 2 delivers 120 watts per channel, and it offers several configuration options for custom installation and multi-zone audio applications. It can drive multiple speakers or subwoofers with ease, thanks to a 2-ohm stable design. The amp can start automatically when your system is turned on via a 12-volt trigger, or when it senses an incoming signal.

Adjustable level controls

Each channel has a level control that's accessible using a screwdriver, via the back panel. That means you can establish maximum volumes for each zone, at safe levels. If you install local in-wall volume controls in each room, then anyone using the system can turn it up as much as they want without risk of damaging the audio equipment (or their ears).

Configuration flexibility

This amp features a handy stereo/mono switch. In stereo mode, it can drive A and B speaker pairs, such as in your main room or in a second zone. In mono mode, it can drive four speakers at the same time in a large room or outdoor space, all playing the same mono signal. And there's a stereo RCA loop output that lets you daisy chain additional amplifiers.

The amp has two mono RCA outputs, one full-range, and another with an 80 Hz low-pass filter for connecting to a powered subwoofer. If you're using the ZoneMaster 2 to power passive subwoofers, there's an 80 Hz crossover switch that affects only the speaker outputs.
