Description
Bose Professional PowerSpace P21000A Power Amplifier
Bose Professional PowerSpace P21000A is a commercial power amplifier designed for zone-expansion and distributed audio applications. It enables high-output amplification for low-impedance and high-impedance loudspeaker systems in retail, hospitality, education, and corporate environments. This makes it ideal for premium commercial installations where flexible power delivery and system scalability are critical.
The amplifier provides two channels of Class D amplification with load-independent outputs that support 4–8 Ω and 70/100V systems without bridging. It features AmpLink digital audio connectivity for simplified multichannel signal distribution from compatible Bose Professional DSPs. I-Share output capability allows combined channel current to deliver increased power to a single zone.
The P21000A supports efficient system operation with automatic standby functionality to reduce power consumption during idle periods. Rack-mount form factor and front-to-back cooling support integration into standard equipment racks. The design supports scalable commercial sound systems with consistent performance across multiple zones.
Key Features
- 1000 W Per Channel Output: Provides high-power amplification for demanding commercial loudspeaker systems
- AmpLink Digital Audio: Supports multichannel uncompressed digital audio over a single Cat 5 cable
- Load-Independent Outputs: Delivers full power to low-impedance or 70/100V loads without bridging
- I-Share Output Mode: Combines channel current to deliver double power to a single zone
- Auto-Standby Operation: Reduces power consumption when audio signal is inactive
