Engineered Sound Processor
Engineers’ and Architects’
Specifications
T
he engineered sound processor shall be a
DSP-based signal processor. The processor
shall include eight general-purpose control
outputs and eight general-purpose inputs
with expansion capabilities for up to a total
of 16 general-purpose control outputs and
16 general-purpose inputs.
Analog audio inputs and outputs shall be
electronically balanced. The maximum input
and output levels shall be +24 dBu. Analog
inputs shall be software-switchable between
microphone and line-level inputs. Phantom
power of +15V shall be provided. A/D and
D/A sections shall be 24-bit, 64x over-sampled.
The processor shall include eight analog audio
inputs and eight analog audio outputs, but be
expandable to a total of 64 audio channels in
one 2U frame. The digital signal processing shall
be performed by a Texas Instruments™ brand
TMS320C6713 DSP chip running at 200 MHz
and utilizing 128Mbit of RAM for delay. All
processing shall be done with 32-bit resolution,
and audio sampling shall be at 48 kHz.
The processor shall include Ethernet, RS-232
and RS- 485 ports. Certifications shall include
cUL, C-Tick and IEC60065, and have a CB report
including all country deviations. Processor and
peripherals shall meet EN55103-1 and EN55103-2
EMC requirements.
The system shall include PC-based design and
control and configuration software, and
communicate with the DSP and other parts of
the system via Ether
net with full IP addressability
and password protection.
The pr
ocessor and design software shall include
the following minimum set of processing modules:
Bose
®
speaker EQs, Bose cr
ossovers, cr
ossovers,
graphic and parametric EQs, routers, delays, matrix
mixers, automatic microphone mixer, signal
generators, meters, compr
esso
r/limiters, duckers,
automatic gain controls, gate, r
oom combiner
and source selectors.
All signal processing modules, parameter sets,
presets and groups shall be directly controllable
by third-party devices via the RS-232 port. It shall
a
lso be possible to designate signal processing
modules in the design file for which asynchronous
RS-232 feedback is requested.
The processor shall be capable of using a
variety of audio cards, including a 4x4 mic/line
input/output card, a four-channel enhanced
dynamic range output card, a four-channel
enhanced dynamic range input card, AES-3
eight-channel input and output cards, a four-
channel mic/line input card and a four-channel
output card. Unit also shall support addition
of a GPIO expansion card to increase the
system’s general-purpose inputs and outputs
to 16 each. Processor shall support a DSP
expansion card, which includes three Texas
Instruments TMS320C6713 DSPs running at
200 MHz and three 128Mbit RAMs for delay.
Processor shall also support a surround sound
card, capable of decoding Dolby
®
Digital, DTS
®
and PCM audio formats.
The processor shall support up to 15 RS-485-based
zone controllers, eight Ethernet-based control
centers and two GPI-based room controllers.
The engineered sound processor shall be
the Bose ControlSpace
®
ESP-88 engineered
sound processor.
Safety and Regulatory Compliance
The ControlSpace
ESP-88 processor meets cUL
(UL 60065 7th edition), C-Tick, PSE and IEC/EN
60065 7th edition, and has a CB report including
all country deviations. It meets FCC Class B,
Canadian ICES-003 Class B and EN55103-1 and
EN55103-2 EMC requirements.
Limited Warranty
The ControlSpace ESP-88 engineered sound
processor is covered by a transferable five-year
limited warranty.
