Bose ESP-880AD Data Sheet
TECHNICAL DATA
ControlSpace ESP-880AD
engineered sound processor
Product Overview
An open-architecture DSP, the Bose ControlSpace ESP-880AD engineered
sound processor is designed for a wide variety of applications — from small,
self-contained projects to large, networked systems. It features integrated
Dante™ audio networking, 8x8 analog audio I/O, a Bose AmpLink output,
and a front-panel RJ-45 Ethernet connection for localized configuration and
monitoring. Engineered for precise performance, the ControlSpace ESP-880AD
oers advanced digital signal processing with 48 kHz/24-bit audio conversion,
low-latency, and ultra-low noise operation.
PROFESSIONAL
Applications
Designed for a wide range of applications,
including:
• Auditoriums
• Places of worship
• Resorts and hospitality venues
• Retail stores
• Educational institutions
Key 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 32x32 audio channels for
connection to other Dante-enabled products.
• Integrated AmpLink connection uses standard CAT 5 cables to send up to
8 channels of low-latency, uncompressed digital audio to compatible 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.
• 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.
• Supports industry-standard control systems using a comprehensive serial
protocol through onboard RS-232 and Ethernet ports, with available drivers for
AMX and Crestron-based systems.
