PRODUCT DESCRIPTION
ESP-88 Chassis Overview:
The Bose ® ControlSpace ® ESP-88 engineered sound processor is a flexible, expandable and
high quality audio signal processor for engineered sound applications such as churches, the-
aters, auditoriums, and sports venues.
The base model (ESP-88) includes eight inputs (microphone or line-level selectable) and eight
line level outputs. Four available audio slots allow the addition of up to 16 more analog audio
channels – inputs, outputs or a combination – or up to 32 more digital audio channels (AES3) as
inputs, outputs or a combination.
For large applications, multiple ESP-88s can be used per system. Multiple choices of user
controllers are available to provide end-users with simple, easy-to-use control of their
ControlSpace system.
The Bose ControlSpace Designer software is used to design systems and configure the
ESP-88 and user controllers. The software runs on a PC and communicates to the ESP-88 over
Ethernet.
Features and functions:
• Expandable and flexible cardframe architecture
• Eight mic/line analog audio input channels
• Eight line level analog audio output channels
• Four open audio expansion slots allow up to 32 analog audio channels total in a 2U chassis
• DSP expansion slot allows DSP processing power and delay times to increase fourfold
• Eight general purpose control inputs and eight general purpose control outputs (GPIO)
• GPIO expansion slot allows up to 16 control inputs and 16 control outputs
• All audio input and input channels feature tricolor level LEDs
• Design, control and configuration via PCbased software and Ethernet connection.
• Large set of signal processing modules including: Bose speaker EQs, Bose crossovers,
graphic and parametric EQs, routers, delays, matrix mixers, signal generators,
meters, compressors/Limiters, duckers, automatic gain controls, gate and source selectors.
Modularity and Expansion
Flexible Architecture
The ESP-88 employs a flexible, modular architecture. The flexible architecture provides two
levels of DSP performance – up to 32 general-purpose I/O and up to 64 digital audio channels –
or up to 32 analog audio channels.
The base model ESP-88, includes a DSP card, two 4x4 Mic/Line cards and one GPIO card. In
this configuration, four audio and one GPIO slot are available for expansion.
Three types of optional cards are available: DSP expansion; GPIO; and Audio.
DSP Expansion Card - Daughter card for main DSP card. Increases performance by 300%.
One card can be added to an ESP-88.
GPIO Card
Fits in one of the two GPIO slots. Eight control inputs and eight control outputs. One GPIO card
can be added to an ESP-88.
