Audio Processing Node
The audio processing node shall be a 2RU industrial package designed for fixed installation in engineered audio and communications systems. The unit shall
include an architecture based on an integrated floating-point Digital Signal Processor (DSP) engine with at least 3 DSP chips. The DSP shall operate with a
common digital audio bus with support for at least 448 simultaneous high-speed digital audio channels. The digital audio bus shall include an external expansion
port that supports bus-level connectivity for additional units. Separate transmit and receive ports shall be provided for the digital audio bus. Software devices
shall be included to allow the digital audio expansion ports to be easily integrated into the configuration file. The audio processing node shall include a
software-based configuration and control. The DSP shall be completely configurable via a Windows-based software system, with additional tools for creating
user interface clients and integration with third-party control systems. Audio device algorithms shall support custom I/O, control and signal flow design and
shall be integrated within the design environment for intuitive system configuration. This software shall include an XML architecture and support for standard
Ethernet management, including, but not limited to SNMP, shall be standard from an integrated, rear panel LAN port. The audio processing node shall include
an embedded Linux operating system. The operating system shall reside on non-mechanical IDE storage media. The storage system shall include support
for reading/writing data from the operating system, configuration software and the front panel. Audio file support for .wav audio shall be standard and shall
be completely integrated with the unit’s software tools. A non-mechanical storage device of at least 256MB shall be used as the primary storage media and
operating system root. The audio processing node shall include a modular I/O card bay system for support of four expansion cards. Each expansion bay shall
be capable of supporting not less than 16 inputs and 16 outputs of simultaneous audio. Cards shall be available for microphone and line level analog audio with
options for digital and proprietary audio transports. The audio node shall include a CobraNet or Dante audio transport module with support for at least 64
20-bit digital audio channels. Separate software devices shall be provided for integrating The audio networking module I/O into the configuration file. The
audio processing node shall include support for serial data transport via the RS-232 and EIA-422/485 ports. All data transports, including Ethernet, shall be
available simultaneously and shall include software devices for integration into the configuration file. The audio processing node shall include an integrated GPIO
control system with at least 16 configurable low-voltage, low-current ports and 4 configurable high-current ports. All GPIO ports shall include software devices
for integrating their function into the configuration file. The GPIO connections shall be externally terminated with a DIN-rail breakout assembly (available
separately). The audio processing node shall include a front panel interface with LCD display. Navigation of the display shall include a rotary data wheel with
push switch and at least four context-sensitive soft buttons. Dual color status LEDs shall be included on the front panel for monitoring network status, storage
and power conditions. The audio processing node shall be fan cooled with a front-panel intake and shall operate with a modular universal computer-grade
power supply. The audio processing node shall be the MediaMatrix NION n3 or approved equal.
