The ControlSpace ESP-00 Series II engineered sound processor offers high-quality signal processing through a flexible audio platform. Install up to eight analog and/or digital audio expansion cards to create customized audio systems. Onboard connectivity includes Ethernet, RS-232, expandable GPIO, and support for elegant Bose® control centers and volume controls.


Flexible I/O through a customizable card-frame design. With a powerful DSP core, the ESP-00 Series II processor accommodates up to 64 channels of audio over 8 open card slots, and general purpose I/O (GPIO) expansion up to 16 control inputs and 16 control outputs

High-quality open-architecture DSP supports 48 kHz sample rate/24-bit conversion, uses a floating-point DSP and operates at low latencies for sound system precision

I/O expansion cards cover a number of audio channel requirements from mic/line analog to Dante™ networking. These cards offer different audio options to populate the 8 open card slots

Support for popular network protocols – Allowing integrators more flexibility in selection, the ControlSpace ESP-00 II processor supports popular audio networking protocols Dante™ and CobraNet® for interconnection with other products and audio systems

A large suite of signal processing algorithms is available. These include automatic mic mixing, multiband graphic and parametric EQs, Bose loudspeaker libraries, signal generators, routers, mixers, AGC’s, duckers, gates, compressors, source selectors and delays

A variety of control options. The ControlSpace ESP-00 II processor is compatible with five user control interface options and can integrate with industry-standard control systems using a comprehensive serial protocol through onboard RS-232 and Ethernet ports

ControlSpace® Designer™ software is used to configure both the signal processing and control capabilities of ControlSpace ESP processors. With ControlSpace Designer™ software it is possible to design, configure, control and monitor all Bose® networked system electronics from a single software application

What are the new features of the Bose ControlSpace engineered sound processors?

The flexible card-frame ControlSpace ESP-88 and ESP-00 processors have been replaced by the ControlSpace ESP-00 Series II engineered sound processor. The ESP-00 II features all of the functionality and card options available with the original ESP-00 processor but with enhanced DSP capacity and a new look. The ESP-00 II can be further augmented by complementary ESP-880, ESP-1240 and ESP-4120 engineered sound processors which can be used together to route and share audio in larger, multi-zone installations.

How many audio channels can the ControlSpace ESP-00 II processor manage?

The ESP-00 II processor has eight open audio card slots for supporting up to 64 audio channels. The processor allows both input and output cards to be used together in the same chassis. Analog cards are currently offered in a 4-channel form factor card, effectively limiting the analog channel capacity to be 32 channels, while digital cards are only limited by the max 64 channel limitation of the processor.

How many GPIO ports are available?

The ESP-00 II processor comes pre-loaded with one GPIO card offering 8 general-purpose inputs and 8 general-purpose outputs. A second card slot is available using an accessory card to double the amount of GPIO lines.

Is it possible to monitor and control the ControlSpace system outside the installation facility?

Yes.  ControlSpace systems can be monitored and controlled remotely over a suitable connection, e.g., VPN

What cards come preinstalled with the ControlSpace ESP-00 Series II?

The ESP-00 II can be configured for different input and output requirements, but ships without any audio cards—they must be ordered separately. The processor ships with one GPIO II card which includes eight general purpose control inputs and eight general-purpose control outputs.

Does ControlSpace Designer software version 4.1 work with Microsoft® Windows® 8?

ControlSpace Designer v4.1 has been fully tested on the Windows 7 and 8 operating systems, and is compatible with both. Please note that to use the Windows 8 operating system, you must manually install the .NET Framework v3.5.

Can ControlSpace systems integrate with AMX/Crestron controls?

Yes. All signal processing modules, parameter sets and groups are directly controllable by third-party devices via the RS-232 port or Ethernet (Serial over Ethernet).

Are there iOS or Android™ apps for use with the ESP-00 II?

Yes, ControlSpace Remote is a control application from Bose that allows complete control of ControlSpace and PowerMatch systems from iOS and Android products.

Are the ControlSpace systems' engineered sound processors used for voice override for emergency applications?

No. ControlSpace systems' components are not approved for life-safety applications. Ducking signal processing modules are available and can be used for paging applications. However, they generally require some non-audio user input (such as a push-to-talk control signal) in order to override currently selected sources.

Can I email ControlSpace Designer software program files?

Yes, “.csp” files are quite small in file size and can be emailed.

What is the warranty of the ControlSpace ESP-00 Series II engineered sound processor?

The ControlSpace ESP-00 II processor is covered by a five-year limited warranty that is fully transferable.
