Overview of the Digital Alert Systems R197AV Audio/Video Switch
The Digital Alert Systems R197AV is a versatile and powerful 4-channel switching system designed for audio and video management in broadcast and emergency alerting environments. This unit offers local and network control for seamless switching between stereo audio or audio-follow-video (A/V) and RF signals. With the ability to handle four independent channels, the R197AV is an ideal solution for EAS (Emergency Alert System) integration, allowing broadcasters to easily switch program feeds for alert scenarios, program isolation, or blackout switching. This system offers a reliable and scalable solution for those looking to manage multiple media sources effectively.

Key Benefits of the R197AV for Broadcast Operations
For broadcasters, the R197AV offers a robust method for controlling multiple audio and video sources. Its capability to switch between A/V or RF channels makes it ideal for emergency alerts, program isolation, or any situation requiring control over multiple media streams. The unit provides four independent switching channels, each capable of handling both balanced stereo audio and video signals, ensuring flexibility and precision in broadcast operations. The easy-to-use web interface and network control options also simplify remote management, making it an efficient tool for any size of operation.

How the R197AV Enhances Network-Controlled Operations
With network control over TCP/IP, the R197AV offers the convenience of managing the switch remotely, eliminating the need for on-site adjustments. Operators can use a standard web browser to configure and control the unit over any Ethernet LAN, making it easy to integrate into existing broadcast infrastructure. Whether using local contact closures or a network-based interface, users have full control over each relay channel, allowing them to switch between audio/video sources or isolate channels as necessary. This level of control streamlines operations, ensuring that emergency alerts or program changes can be executed swiftly and effectively.

Advanced Switching Features for Broadcast Flexibility
Each of the four independent channels in the R197AV includes a 2 x 1 balanced stereo audio relay switch and a single-pole double-throw dry contact relay, enabling precise control over audio and video routing. The video/RF switch on the R197AV is capable of handling frequencies from DC to 1GHz, ensuring high-quality performance for various broadcast applications. The ability to use devices like Digital Alert Systems’ timer or other GPI devices allows broadcasters to easily integrate the unit into their existing setup for blackout switching, program isolation, or emergency program switching.

Ease of Installation and Use
The R197AV is designed with ease of installation and operation in mind. Powered by a single wall-mounted power supply (included), the system offers a secondary (diode-isolated) power input for optional redundant power supply, ensuring uninterrupted operation during power disruptions. Its compact 1RU form factor saves valuable rack space, while the built-in web server configuration page allows for quick and easy setup using any standard web browser. No special software or cables are required, making the R197AV an accessible solution for broadcasters of all sizes.
