Digital Alert Systems Model R-165A Stereo A/V and IF/RF Relay Panel

What is the Digital Alert Systems R165a Stereo A/V and IF/RF Relay Panel?
The Digital Alert Systems R165a Stereo A/V and IF/RF Relay Panel is a versatile device designed to provide reliable switching for audio, video, and IF/RF signals. This panel features four independent 2x1 (A/B) balanced stereo audio follow video relay switches, making it ideal for professional environments such as broadcast stations, control rooms, and production facilities. The panel is highly flexible, supporting both audio and video signals while also functioning as a high-quality IF/RF 2x1 switch, offering a frequency response of up to 950 MHz. Its robust design allows for seamless integration into existing systems, ensuring smooth operations and reliability.

How the R165a Enhances Audio/Video and RF Switching
The R165a Relay Panel offers significant advantages for managing complex audio/video and RF switch operations. It provides four separate channels, each capable of switching between two input sources for balanced stereo audio and video. The ability to follow video with the stereo audio ensures synchronized audio-visual broadcasts, reducing the potential for delays or mismatches. Additionally, the panel can also handle IF/RF signals, providing the necessary performance for a variety of applications that require high-frequency switching up to 950 MHz. Whether for use in professional broadcast setups or specialized applications, the R165a excels at managing these signals with precision.

Flexible Control Options for Streamlined Operation
The R165a Relay Panel can be controlled via multiple methods, offering flexibility for different types of installations. The switches can be activated through Digital Alert Systems program timers, remote controls, or CATV Cue Tone® receivers, allowing for remote management of the relay switches. Contact closures or logic inputs are used for activation, providing easy integration into automated control systems. These control options ensure that the R165a can fit seamlessly into a wide range of broadcasting and production setups, whether you're working with a manual or automated system.

Auxiliary Relays for Expanded Switching Capabilities
In addition to the primary video and audio relay switches, the R165a also includes two auxiliary relays that can be used for General Purpose Inputs (GPI) or Secondary Audio Program (SAP) switching. This feature significantly expands the versatility of the relay panel, allowing users to incorporate additional control functions, such as monitoring or triggering other equipment in the system. The flexibility of these auxiliary relays makes the R165a ideal for environments that require additional signal routing or equipment control, giving you more options for custom configuration.

Convenient Connectivity and Installation
The R165a Relay Panel is designed for easy integration with other broadcast and production equipment. All interconnections are made at the rear panel, ensuring a clean and organized setup. The stereo audio connections are made via detachable screw terminals, which provide a secure and stable connection. For video and IF/RF connections, the panel uses F connectors, ensuring high-quality signal transfer with minimal loss. The low-power control inputs and optional redundant power supplies ensure that the panel operates efficiently, even in demanding environments where reliability is key.
