Ideal for zone-expansion applications, Bose PowerSpace amplifiers enhance any premium commercial sound installation with clean, reliable power - and digital connectivity. A Bose AmpLink input allows for multiple channels of uncompressed, low-latency digital audio from Bose DSPs via a single Cat 5 cable. The PowerSpace P21000A provides 1000 watts per channel and features versatile outputs that give you the flexibility to deliver full channel power to either low- or high-impedance loads - without bridging - and even send double power to a single zone.
