Bose ControlSpace ESP880 Engineered Sound Processor 

The Bose® ControlSpace® ESP-880 engineered sound
processor is a single-rack-space DSP with an 8x8 analog
audio configuration, built-in ESPLink output, and an open
digital expansion slot ready to accommodate an optional
Dante™ network audio card. This model meets today’s strict
requirements for high-quality signal processing and control
in a cost-effective package. The ESP-880 is designed for a
wide variety of applications ranging from small self-contained
projects to larger networked applications.


• High-quality analog circuitry offers both mic and line-level I/ O, operates with ultra-low noise and 115 dB dynamic range 
• Advanced digital signal processing supports audio at 48 kHz sample rate/24-bit, uses a floating-point open architecture DSP and operates at low latencies for sound system precision 
• Expansion card slot supports the use of accessory networking cards, allowing digital audio to be sent and/or received from other compatible products 
• Optional Dante™ network cards allow ESP processors to closely integrate with other product supporting Audinate®'s Dante audio networking solution 
• Bose® ControlSpace® Designer™ software enables a large set of signal processing modules, such as automatic mic mixing, multiband graphic and parametric EQs, Bose loudspeaker libraries, signal generators, routers, mixers, AGCs, duckers, gates, compressors, source selectors and delays 
• Front panel RJ-45 Ethernet connection enables localized configuration and monitoring, while enabling network passthrough when using a rear-panel network option card 
• Built-in Bose ESPLink output sends up to 8 channels of uncompressed digital audio to ESPLink-equipped Bose PowerMatch® amplifiers 
• A variety of control options – ControlSpace ESP products are compatible with the programmable Bose CC-64 and CC-16 controllers and three simplified zone volume interfaces, as well as potentiometers and switches built by other manufacturers 
• Integration with industry-standard control systems using a comprehensive serial protocol through onboard RS-232 and Ethernet ports
