Introduction
The Bose ControlSpace ESP-880A/ESP-880AD/ESP-1240A/ESP-1240AD engineered sound processor is
an open-architecture DSP with 8 × 8 / 12 × 4 analog audio and a Bose AmpLink output, designed for a wide
variety of applications ranging from small self-contained projects to larger networked applications. It oers
advanced digital signal processing with 48 kHz/24-bit audio conversion, ultra-low noise, and low-latency
operation for sound system precision.
Open-architecture configuration and control is achieved 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 oer an elevated level of functionality for most installed audio installations.
Onboard connectivity includes RS-232, 5 control inputs, 5 control outputs, onboard and 8-channel Bose
AmpLink to send digital audio to AmpLink-equipped Bose amplifiers. The ESP-880AD/ESP-1240AD includes
32 × 32 Dante™ audio networking connectivity and front- and rear-panel Ethernet ports for configuration and
control. The ESP-880AD/ESP-1240AD 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 controls such
as the ControlCenter zone controllers and ControlSpace Remote for wireless control from mobile devices.
Product Features
High-quality analog circuitry oers 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 Dante audio networking supports 32 × 32 audio channels for connection to other Dante-
enabled products (ESP-880AD/ESP-1240AD only)
Built-in Bose AmpLink output sends digital audio to AmpLink-equipped Bose amplifiers
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 with the rear-panel network ports (ESP-880AD/ESP-1240AD only)
A variety of control options: ControlSpace ESP products are compatible with the programmable Bose
CC-64 and CC-16 controllers, ControlCenter zone controllers and ControlSpace Remote clients.
Integration with industry-standard control systems using a comprehensive serial protocol through
onboard RS-232 and Ethernet ports
