Bose Pro CONTROLSPACE ESP-1240A

BOSE PRO
ControlSpace ESP-1240A
engineered sound processor


Product Overview
An open-architecture DSP, the Bose ControlSpace ESP-1240A engineered
sound processor is designed for a wide variety of applications — from small,
self-contained projects to large, networked systems. It features 12x4 analog
audio I/O, a Bose AmpLink output, and advanced digital signal processing
with 48 kHz/24-bit audio conversion. Engineered for precise performance,
the ControlSpace ESP-1240A also features low-latency and ultra-low noise
operation.


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 offers 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 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.
• 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
