Key Features
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
Product Information
• Optional Dante™ network cards allow ESP processors to
closely integrate with other product supporting Audinate®'s
Dante audio networking solution
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.

Bose® ControlSpace® Designer™ software is used for the design,
configuration, real-time operation and monitoring of a system
containing selected Bose system electronics and control centers.
Using a standard drag-and-drop user interface, ControlSpace
Designer software offers the flexibility to quickly and accurately
configure signal processing functions within processors, and to
develop complex control programming for system operation.
When actively connected to the system ControlSpace Designer
software can be used to either control and operate the system
in real time for system set-up and optimization, or may be used
as a system monitor. When configured for monitor mode device
parameters are protected and the system operator only has
access to virtual control panels and amplifier monitor functions.
Parameter sets provide the ability to program and recall system
settings ranging from an individual signal processing parameter
to a complete system setup; while Group controls provide master
volume control of multiple gains, or control of multiple instances of
the same signal processing function type. Both Parameter set and
Group programming functions are easily mapped to the physical
controls of a Bose control center, or may be invoked remotely
using a standard serial protocol or general purpose inputs.
Smart Simulation programming enables designers to test and
modify system control programming while off-line, eliminating
the need to connect to the actual system to configure and test
system control programming. Virtual control centers are included
to test system operation, and all parameter set, group and
general purpose input and outputs may be tested using the Smart
Integrated Dante routing, configuration and monitoring streamlines
setup and control of optional Dante networked audio components.
