Bose Professional ControlSpace ESP-880A DSP 8-Channel Sound Processor (Balanced, Mic/Line Level) 8x8 I/O 48 kHz/24-Bit Sample Rate
Usually arrives in 5-9 business days.
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.
The ESP-880 accommodates a total of 56 audio channels through analog audio connections (8 input, 8 output), ESPLink (8 output), and when an optional Dante™ audio network card is used, an additional 32 channels (16 input, 16 output) are available for signal processing, routing and switching. Alternatively, a Network Control card is available for clean rear-panel control network connections. For standalone applications or convenient service access, a front panel Ethernet connector allows for local configuration and monitoring. Onboard connectivity includes Serial over Ethernet, RS-232, 5 control inputs and 5 control outputs.
Any of the elegant Bose wall-mounted user interfaces— Including the programmable CC-64 and CC-16 controllers and three simplified zone volume interfaces— can be used to control all Bose networkable devices.
Open architecture configuration and control is enabled using Bose ControlSpace Designer™ software where an ever-expanding list of algorithms and improvements offers a high level of functionality for audio installations. Bose single-rack-space ESPs are designed for a wide variety of applications ranging from small self-contained projects to larger networked applications.
