SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on schematics
or by special notes on the parts list. Use only replacement parts that have critical characteristics
recommended by the manufacturer.
2. Make leakage current or resistance measurements to determine that exposed parts are
acceptably insulated from the supply circuit before returning the unit to the customer.
Use the following checks to perform these measurements:
A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a
leakage current tester or a metering system that complies with American National Standards
Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL)
UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit AC switch first in the ON position
and then in OFF position, measure from a known earth ground (metal waterpipe, conduit, etc.)
to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads,
metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical
return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the
unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE
LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE
ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper
wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure
the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic
cabinet part on the unit. When testing 3 wire products, the resistance measured to the product
enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed
input/output connectors should be between 4 and infinite MOhms. When testing 2 wire prod-
ucts, the resistance measured to exposed input/output connectors should be between 4 and
infinite MOhms. If it is not within the limits specified, there is the possibility of a shock hazard,
and the unit must be repaired and rechecked before it is returned to the customer.
CAUTION: The Bose®ControlSpace®ESP-88 System, CC-16 and CC-64 Controllers
contains no user-serviceable parts. To prevent warranty infractions, refer servicing
to warranty service stations or factory service.

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.

PRODUCT DESCRIPTION
CC-16 Zone Controller
The Bose®ControlSpace®CC-16 zone controller is an elegant wall-
mounted device designed to provide end-user control of ControlSpace
systems. Custom programming allows the CC-16 to control a variety of
the system elements, from switching audio sources to selecting
“scenes” or system configurations. The CC-16 features a bitmap LCD
and four buttons for displaying and controlling the system settings.
The CC-16 connects to the ControlSpace Engineered Sound Proces-
sor (ESP-88) at the RS-485 port. Up to fifteen CC-16 units can be
used per each ESP-88 to provide localized control of the system. The
maximum distance from ESP-88 to CC-16 is 2000 feet. As a net-
worked device, remote reprogramming is possible at any time.
Features and Functions
• 122 x 32 pixel backlit blue LCD
• LCD displays volume level and source/scene/preset setting
• Select up/down buttons for selecting sources or scenes
• Volume up/down buttons for controlling one or more gain controls
• IR receiver (for IR remote controls)
• RS-485 network supports up to fifteen CC-16 units per ESP-88
• DIP-switch for specifying network address and termination
• Universal mounting bracket
• UL and CE listed
CC-64 Control Center
The Bose ControlSpace CC-64 control center is an
elegant, programmable, networked controller that
provides users with a simple and logical interface to
their ControlSpace system. Because the controller is
completely programmable, you can customize the
ControlSpace system, making only certain controls
available, and simplifying user interaction with the
system.
The CC-64 provides four rotary encoders with
circular LED arrays for a userfriendly method of
managing gain settings or scene selections. A fifth encoder provides control over programmed
“scenes” or presets. Four bank switch buttons redefine the four Gain/Selector control knobs,
providing quick access for up to 16 system gain controls or selectors. A large, 2-line by 40-
character backlit LCD provides the user with the names of the system elements they are con-
trolling (gains, presets, etc.).
Using custom programming, the CC-64 can manage a variety of system elements, including
audio sources, scene selection settings, and specific system configurations. Each gain control
can be ganged so that a single control can be mapped to as many as sixteen system gains. The
CC-64 also supports a “custom mode” – intended for installers, not end users – in which any
parameter in the system can be viewed and changed using the LCD display and control knobs.
