Architect's & Engineer's Specification
E Desk™ Digital Audio Platform
ARCHITECTS & ENGINEERS SPECIFICATION (February 1, 2004)
The Digital Audio Platform shall be an 8-in/8-out (8x8) hardware
configuration. Inputs and outputs shall use internal 24-bit A/D & D/A
converters operating at a sample rate of 48kHz. All internal processing shall
be digital (DSP). Electronically balanced analog inputs and outputs shall be
provided on plug-in barrier-strip connectors. Analog inputs shall be
individually programmable to accept either microphone or line level signals.
The hardware shall include six 60MHz 32-bit floating point SHARC DSPs, an 80MHz
32-bit Power PC host processor, 32MB SDRAM, and 8MB Flash ROM. Software shall
be provided for creating/connecting DSP system components within each hardware
unit. Available system components shall include (but not be limited to) various
forms of: mixers, equalizers, filters, crossovers, dynamics/gain controls,
routers, delays, level controls, level meters, and tone generators. Ethernet
communications shall be utilized for software control, configuration, and DSP
sharing. CobraNet(TM) technology shall transport digital audio over fast
Ethernet, allowing multiple units to share digital audio. After initial
programming, systems may be controlled using either TCP/IP or RS-232 serial
communication by third party control systems such as AMX(TM) and Crestron(TM).
The E Desk 4040c shall be outfitted with CobraNet for multi-unit network
applications and to expand total inputs and outputs to 40 channels. Multi-unit
network applications require an external 10/100Base-T Ethernet switch. All
CobraNet & Ethernet connections shall be via CAT5 cable or fiber-optic.
Software shall operate on a PC computer, with network card installed, running
Windows(TM) NT 4.0/2000/XP.
The Digital Audio Platform shall be E Desk.
