Description
The Parasound ZoneMaster ZM2350 is a 2-channel amplifier with a built-in subwoofer crossover, delivering 350W x 2 into 8Ω or 600W x 2 into 4Ω/2Ω. It combines a Parasound-designed Class AB input stage with a premium Class D power stage, and includes flexible modes for driving multiple speaker pairs, in-wall subwoofers, or mono applications.
Features
- 2Ω stable output for driving multiple speaker pairs
- Two pairs of speaker outputs with A/B buttons and rear lockout switch
- Switchable high pass filter (30Hz or 80Hz)
- Automatic on/off via 12V trigger (with looping output) or audio signal sensing
- Speaker level input for systems lacking preamp outputs
- Subwoofer mode for driving multiple in-wall subs without an external crossover
- Mono mode combines L and R channels for single-speaker applications
- Mono full-range preamp output and 80Hz/24dB-per-octave subwoofer preamp output
- 0.5W standby consumption, meeting EU and Energy Star requirements
- 2U rack mounting hardware included
