Parasound ZoneMaster ZM2350 - 2 Channel Power Amplifier

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.

• 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
