Bose Professional Powerspace P4300A 4-Channel Power Amp with AmpLink

The Bose 803288-1110 is a four-channel PowerSpace P4300A amplifier that supplies 300 watts on each channel while occupying only a single rack unit. It gives system designers the freedom to power loudspeakers that present a 4 or 8 ohm load or distributed lines that require 70 or 100 volt operation, all without bridging or rearranging the wiring.

Integration is straightforward. An AmpLink port carries up to eight channels of uncompressed, low-latency digital audio through one Cat 5e cable, keeping cable runs clean and reducing potential failure points. Four analog inputs are on hand for local sources, and removable Euroblock connectors speed up installation. When a zone needs extra headroom, the I-Share function lets you combine the power of two channels and send the total output to that single zone.

The amplifier conserves energy with an auto-standby feature that powers the unit down when the signal is idle, yet wakes it within milliseconds when audio returns. A front-to-back cooling path protects components in tightly packed racks.

Because of its mix of power, flexibility, and efficient size, the P4300A fits naturally in retail stores, restaurants, fitness studios, houses of worship, conference centers, and any venue that relies on dependable background or foreground sound. Integrators who need an amplifier that handles both low-impedance cabinets and distributed ceiling speakers will find it a practical, long-term solution.
