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 16 balanced inputs that can be selected to a single mono output. The signal path in both models is passive, utilizing sets of relays that allow analog and digital audio signals, as well as control signals, to be passed through the switcher. No active circuitry in the signal path; relay switching is used throughout.
Control and monitoring can be accomplished in various ways to accommodate nearly every interface situation. RS-232 serial and standard GPIO control and status indications are available, in addition to a LAN interface that supports SNMP v2. The serial interfaces are programmable by the user to input serial commands for virtually any interface. A pre-programmed RS-232 command set supports the Sage ENDEC and Digital Alert Systems DASDEC™ EAS Encoder/Decoder products. With the programming function, you can create a custom serial interface tailored to your specific requirements.
The RAS-216 also supports a GPIO interface for remote control, and two types of remote control panels are available from BDI. One supports GPIO, and the other is a serial interface panel for easy interfacing over longer cable runs. The provided Microsoft Windows software and SNMP MIB file allow configuration of serial communication, channel labels, and switcher names.
