Versatile High-Power Output

The P21000A delivers a formidable 1000 watts per channel, providing ample headroom for demanding commercial applications. Its load-independent design allows you to drive full power into low-impedance (4-8Ω) or high-impedance (70/100V) systems on either channel without bridging, offering exceptional flexibility for system designers and installers.

I-Share Mode for Maximum Power

For applications requiring even greater power to a single zone, the innovative I-Share mode allows you to combine the power of both channels. This delivers a massive 2000-watt mono output, perfect for driving large subwoofers or powering a high-output area without needing a larger, separate amplifier.

Simplified AmpLink Connectivity

Integration is streamlined with the inclusion of an 8-channel Bose AmpLink digital audio input. Using a standard Cat 5 cable, you can receive multiple low-latency audio channels from compatible Bose DSPs, reducing termination time, potential wiring errors, and overall installation complexity.

Yes, each channel's output is independent, allowing you to run one channel into a low-impedance load and the other into a high-impedance 70V or 100V line simultaneously.

AmpLink is a Bose digital audio transport protocol that sends up to 8 channels of audio over a standard shielded Cat 5 cable. While it simplifies connection to Bose DSPs, you can also use the standard balanced analog inputs.

While it provides high-quality power, the P21000A is designed for commercial installations, featuring Euroblock connectors and AmpLink inputs not typically found in home audio.

No, the P21000A is a dedicated power amplifier. It is designed to be paired with external digital signal processors (DSPs), like those in the Bose ControlSpace family, for all signal processing.

The Bose P21000A features a compact and efficient design, requiring only a single standard rack unit (1U) of vertical space.

I-Share mode combines the power of both amplifier channels into a single, high-power mono output of 2000W. This is ideal for driving large, power-hungry loads like subwoofers or a single, very loud zone.
