PowerSpace P4300A versatile power amplifier
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.

- 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
