Architect's & Engineer's Specifications The audio network interface shall be a 1RU-high, 1/2RU-wide industrial package designed for fixed installation in engineered audio and communication systems. It shall provide eight analog audio channels, each independently configurable as either a line-level analog output from the audio network, or a mic/line analog audio input to the audio network. The audio network shall be CobraNet, operating on a 100Base-T Ethernet physical interface. The audio output signals shall be monitored in the analog domain, and this monitoring signal shall be capable of transmission on the CobraNet network. The analog audio inputs shall provide 48V phantom powering for microphones, and remote control of gain. The audio outputs shall provide remote control of level in the analog domain, and mute by physical disconnection of audio signal drivers from the external connectors. The audio network interface shall be capable of being powered from Power-over-Ethernet according to standard IEEE802.3-2008, or from 24V DC. The audio network interface shall feature front-panel meters to indicate audio signal level on each channel, and status indicators for the network connection, power and system fault condition. The audio network interface shall provide eight general-purpose I/O connections, each independently configurable as either a logic input, logic output, analog control voltage input, or high-voltage output. The audio network interface shall provide a serial port, configurable to operate on either RS-232, EIA-485 or EIA-422 physical protocols. All connections except for the Ethernet port shall be on Mini Euro connectors. Remote control and monitoring via Ethernet shall be possible for all functions and settings, including audio input and output interface settings, audio level metering, CobraNet settings, GPIO configuration and signals, contact closure circuits and serial port configuration and data. A software device to control and monitor the audio network interface shall be available for integration into the configuration file. The audio network interface shall be the MediaMatrix Cab 8n or approved equivalent.
