Ideal for zone-expansion applications, Bose Professional PowerSpace amplifiers enhance any premium commercial sound installation with clean, reliable power — and digital connectivity. A Bose Professional AmpLink input allows for multiple channels of uncompressed, low-latency digital audio from Bose Professional DSPs via a single Cat 5 cable. The PowerSpace P4300A provides 300 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. For premium commercial applications, PowerSpace amplifiers provide the power and performance to get the job done — pure and simple.
FEATURES
300 watts per channel and works seamlessly with loudspeakers, DSPs, and controls to create complete commercial sound systems
AmpLink input for simplified multichannel digital audio connection to compatible DSPs, reducing terminations and related points of failure
Load-independent outputs deliver full channel power to either low-impedance loads (4-8 Ω) or high-impedance (70/100V) loads without bridging
I-Share outputs deliver 2x power level by combining the current of two channels
Auto-standby mode saves power when audio signal falls below a set threshold, then wakes when audio returns
Applications

Retail stores
Restaurants and bars
