AudiaFLEX Digital Audio Platform
ARCHITECT'S & ENGINEER'S SPECIFICATION
The Digital Audio Platform shall be available in various I/O configurations.
Inputs and outputs shall be specified by pairs, in any combination, up to a
total of 24. Inputs and outputs shall be analog, with internal 24-bit A/D & D/A
converters operating at a sample rate of 48kHz. All internal processing shall
be digital (DSP). Electronically balanced inputs and outputs shall be provided
on plug-in barrier-strip connectors. Inputs and outputs shall be individually
programmable for either microphone or line level signal.
Each hardware configuration shall include six 60MHz 32-bit floating point
DSPs, an 80MHz 32-bit 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, remote controls, meters, generators, and diagnostics.
Ethernet communications shall be utilized for software control, configuration,
and DSP distribution. Each hardware configuration shall be available with
CobraNet™ (for multi-unit network applications) or without CobraNet (for stand-
alone applications). CobraNet technology shall transport digital audio over
fast Ethernet, allowing multiple units to share digital audio. Multi-unit
network applications shall require an external 10/100Base-T Ethernet switch.
All CobraNet and Ethernet connections shall be via CAT5 cable or fiber-optic.
After initial programming, systems may be controlled using either TCP/IP or RS-
232 serial communication by third party control systems (such as AMX
®
and
Crestron
®
), by PC computer, and/or by dedicated remote control devices.
Software shall operate on a PC computer, with network card installed, running
Windows® 2000/XP.
The Digital Audio Platform shall be AudiaFLEX.
AudiaEXPI Input Expander
ARCHITECT'S & ENGINEER'S SPECIFICATION
The Input Expander shall provide eight mic/line analog audio inputs on rear
panel plug-in barrier strip connectors. Front panel level controls and peak
indicators shall be provided for adjustment of the analog audio input signals.
Internal analog-to-digital signal conversion shall be 24-bit, with a sample rate
of 48kHz. Eight channels of digital audio output shall be provided via
CobraNet, on two rear panel RJ45 connectors. A rotary encoder and LCD screen
shall be provided on the front panel for programming and setup.
The Input Expander shall be represented as a functional block within AUDIA™
software, for easy inclusion into system designs. The Input Expander shall also
be capable of providing additional analog audio inputs to other CobraNet
compliant systems or devices. The Input Expander shall be CE marked, include a
UL listed power source, and carry a five-year warranty.
The Input Expander shall be AudiaEXPI.
AudiaEXPO Output Expander
ARCHITECT'S & ENGINEER'S SPECIFICATION
The Output Expander shall provide eight channels of digital audio input via
CobraNet, on two rear panel RJ45 connectors. Internal digital-to-analog signal
conversion shall be 24-bit, with a sample rate of 48kHz. Eight line-level
analog audio outputs shall be provided on rear panel plug-in barrier strip
connectors. Front panel level controls shall be provided for adjustment of the
analog audio output signals. A rotary encoder and LCD screen shall be provided
on the front panel for programming and setup.
The Output Expander shall be represented as a functional block within AUDIA™
software, for easy inclusion into system designs. The Output Expander shall also
be capable of providing additional analog audio outputs from other CobraNet
compliant systems or devices. The Output Expander shall be CE marked, include a
UL listed power source, and carry a five-year warranty.
The Output Expander shall be AudiaEXPO.
