About
Parasound ZoneMaster 2350 Universal 2 Channel Amplifier with Sub Crossover is designed from the ground up to be as friendly to custom installations as it is powerful. With 600 watts x 2 available, it will drive any speaker or passive subwoofer with ease. Unique preamp outputs for full-range mono and low-pass mono provide unsurpassed flexibility. A switch engages an analog 30 Hz or 80 Hz high-pass filter to prevent heavy bass from reaching smaller speakers. A built-in analog 80 Hz, 24 dB/octave low-pass filter makes the ZoneMaster 2350 an outstanding amplifier for driving multiple in-wall passive subwoofers without the need for external crossovers.

Benefits of Parasound ZoneMaster 2350 Universal 2 Channel Amplifier with Sub Crossover:
Varied Features

The Speaker Level Input enables the ZoneMaster 2350 to connect to any audio receiver or stereo system, even if it lacks preamp output jacks. This is a high impedance input, and the ZoneMaster 2350's Speaker Level Input can connect to the speaker terminals on any receiver or amplifier. This will not reduce the output power or degrade the sound quality of the speakers that are already connected directly to the "host" receiver or amplifier. Speaker level audio is internally converted to line level and routed to the Loop Out, Mono Out and Sub Out jacks. These provide line level outputs to drive additional power amplifiers and powered subwoofers.
