Bose Professional PowerSpace P4300A 300W Power Amplifier for 4-Channel Zone Expansion

Deliver consistent, professional audio across multiple zones with the Bose Professional PowerSpace P4300A power amplifier — engineered for commercial installations, security paging, and AV backbone systems. This 4-channel pro amplifier supplies 300W per channel with load-independent outputs that support both low-impedance (4–8Ω) and high-impedance (70/100V) speaker lines, giving integrators flexibility without the need for bridging. AmpLink digital connectivity lets you stream multichannel, low-latency audio from compatible Bose DSPs over a single Cat5 cable, simplifying networking and reducing termination points in large surveillance, monitoring, or retail environments. When you need extra output for a high-demand zone, I-Share combines channels to deliver double power to a single area. Built-in auto-standby conserves energy during idle periods while Ethernet control and robust construction ensure reliable operation for 24/7 monitoring and public-address tasks. Ideal for system integrators and AV professionals, the PowerSpace P4300A streamlines zone expansion and improves system uptime.
