Bose ControlSpace ESP-1240 Sound Processor
ControlSpace® ESP-1240 engineered sound
processor is an open-architecture DSP with 12x4 fixed
analog audio, built-in 8-channel ESPLink output and a rearpanel
digital expansion slot offering IP-based network audio
and control card options. This model meets today’s strict
requirements for high-quality signal processing and control
in a cost-effective package. The ESP-1240 is designed for a
wide variety of applications ranging from small self-contained
projects to larger networked applications.
Product Information
The ESP-1240 accommodates a total of 56 audio channels
through analog audio connections (12 input, 4 output),
ESPLink (8 output), and when an optional Dante(tm) audio
network card is used, an additional 32 channels (16 input,
16 output) are available for signal processing, routing and
switching. Alternatively, a Network Control card is available
for clean rear-panel control network connections. For
standalone applications or convenient service access, a
front panel Ethernet connector allows for local configuration
and monitoring. Onboard connectivity includes Serial over
Ethernet, RS-232, 5 control inputs and 5 control outputs.
Any of the elegant Bose wall-mounted user interfaces—
including the programmable CC-64 and CC-16 controllers
and three simplified zone volume interfaces—can be used to
control all Bose networkable devices.
Open architecture configuration and control is enabled
using Bose ControlSpace Designer™ software where an
ever-expanding list of algorithms and improvements offers
a high level of functionality for audio installations. Bose
single-rack-space ESPs are designed for a wide variety of
applications ranging from small self-contained projects to
larger networked applications.
Applications
Designed for a wide range of applications, including:
• Auditoriums
• Houses of worship
• Resorts and hospitality venues
• Retail stores
• Schools and universities
• Multi-purpose spaces
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
• Expansion card slot supports the use of accessory
networking cards, allowing digital audio to be sent and/or
received from other compatible products
• Optional Dante™ media networking card allows single rackspace
ESP products to closely integrate with Bose or other
manufacturers’ products and systems
• 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 when using a rear-panel network option card
• Built-in Bose ESPLink output sends up to 8 channels
of uncompressed digital audio to ESPLink-equipped Bose
PowerMatch® amplifiers
• A variety of control options – ControlSpace ESP products
are compatible with the programmable Bose CC-64 and
CC-16 controllers and three simplified zone volume interfaces,
as well as potentiometers and switches built by other
manufacturers
• Integration with industry-standard control systems using
a comprehensive serial protocol through onboard RS-232 and
Ethernet ports
