Bose ControlSpace ESP-880AD engineered sound processor

The Bose ControlSpace ESP-880AD is an open-architecture DSP. The Bose ControlSpace ESP-880AD is engineered sound processor is designed for a wide variety of applications - from small, self-contained projects to large, networked systems. The Bose ControlSpace ESP-880AD features an integrated Dante™ audio networking, 8x8 analog audio I/O,a Bose AmpLink output, and a front-panel RJ-45 Ethernet connection for localized configuration and monitoring. The Bose ControlSpace ESP-880AD is engineered for precise performance that can offers an advanced digital signal processing with 48 kHz/24-bit audio conversion, low-latency and ultra-noise operation.

Onboard connectivity includes front and rear-panel Ethernet ports, RS-232 serial, five control inputs, five control outputs, and an 8-channel Bose AmpLink port for sending digital audio to Bose amplifiers. The ESP-880AD 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 zone controllers and mobile-ready ControlSpace Remote.

Configure and control the ESP-880AD using Bose ControlSpace Designer software, where a large set of signal processing modules, such as automatic mic mixers, multiband graphic and parametric EQs, Bose loudspeaker libraries, signal generators, routers, mixers, AGCs, duckers, gates, compressors, source selectors, and delays offer an elevated level of functionality for general installed audio applications. Program end-user controls and automation events visually with less complication and more predicable operation on-site. With ControlSpace Designer software, an entire audio system with multiple components can be configured, monitored, and tuned live for creating custom-designed audio and control solutions that save design time and offers outstanding flexibility to better meet client needs.
