Bose ControlSpace ESP-880A

The Bose ControlSpace ESP-880A is an open-architecture DSP sound processor designed for a wide variety of applications from small self contained projects to large network systems. The ESP 880A features 8x8 analogue I/O, a Bose AmpLink output and advanced digital signal processing with 48kHz/24-bit audio conversion.

Onboard connectivity includes rear-panel Ethernet for configuration and control, RS-232, 5 control inputs, five control outputs and an 8-channel Bose AmpLink port for sending digital audio to Bose amplifiers. The ESP-880A also supports integration with industry-standard control systems, such as Crestron and AMX, and can be used with any of the compatible Bose Professional end-user control options such as the ControlCenter digital zone controllers and mobile-ready ControlSpace Remote.

Features

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
Integrated AmpLink output connection uses standard CAT 5 cables to send up to 8 channels of low-latency, uncompressed digital audio to compatible Bose amplifiers
Bose® ControlSpace® Designer software enables a large set of signal processing modules, such as automatic mic mixers, predictive feedback suppressors, room combiners, multiband graphic and parametric EQs, Bose loudspeaker libraries, signal generators, routers, mixers, AGCs, duckers, gates, compressors, source selectors and delays
A variety of control options – ControlSpace ESP products are compatible with programmable Bose CC-64 controller, ControlCenter zone controllers and ControlSpace Remote clients.
Supports industry-standard control systems using a comprehensive serial protocol through onboard RS-232 and Ethernet ports, with available drivers for AMX and Crestron-based systems
