The RAS-208 and RAS-216 are programmable passive audio switchers. The RAS-208 is for stereo operation and can accommodate up to eight (8) stereo balanced pairs to be switched to a single stereo output. The RAS-216 is designed for monaural operation with up to sixteen (16) balanced inputs that can be selected to a single mono output. The signal path in both models is passive, utilizing relay sets that allow analog and AES3 digital audio signals, as well as control signals, to pass through without modification. No active circuitry is in the signal path; relay switching is used throughout.
Control and monitoring can be accomplished via RS-232 serial, GPIO, and LAN SNMP v2 interfaces. The serial interfaces are programmable by the user to input serial commands for virtually any interface. A pre-programmed RS-232 command set supports Sage ENDEC and Digital Alert Systems DASDEC™ EAS Encoder/Decoder products. The RAS-216 also supports a GPIO interface for remote control, with optional remote control panels from BDI. Microsoft Windows application software and SNMP MIB files are provided for configuration, including channel naming and switcher setup.
