Aqua Broadcast Cobalt CH-1 Fully featured 1+1 Changeover Switch

Aqua Broadcast CH-1 Changeover switch

A versatile controller unit designed to monitor and manage redundant broadcast systems for FM radio transmission. This system ensures smooth transitions between transmitters, minimizing downtime in the event of a failure. It offers both automatic and manual operation modes with remote control or local management for maintenance and system testing. 

Built on the proven COBALT platform, the CH-1 gives you added confidence when using a secondary or backup transmitter. The unit features a built-in DPDT relay, offering more flexibility than standard SPDT relays and adding the possibility of testing the backup exciter on a dummy load without interrupting the main transmission. 

You can use the internal relay for exciters or low power transmitters but if you require to switch greater power transmitters you can easily integrate external RF switches from renowned brands like Spinner through the rear connectors.

A set of interlocks on the rear panel is also included, along with a +48VDC power input for added redundancy in critical scenarios.

To simplify system configuration, most settings can be adjusted via software. This includes input status, output controls and interlock polarities, fault detection methods (both digital and analogue), timers, and analogue thresholds. All are fully user-programmable in software for added convenience

Controls and monitoring are available through various methods, including web, SNMPv1, v2C, and v3, as well as email alerts and notifications.

The front panel includes the easy-to-use COBALT joystick and a clear OLED display. A set of LED indicators provides real-time status updates, with a clear diagram showing the current system operation.

Setup via the GUI is quick and intuitive. You can set up various time settings to allow for faster changeovers when needed and define the number of permissible automatic switches. On the local mode, full control from the control panel is given to the engineers during maintenance without external interference. By using the handy scheduled tests you will ensure the backup transmitter is always ready when it is most needed.   

Built for redundancy, designed for safety, and engineered for excellence, the Aqua Broadcast Changeover System keeps your broadcast on air, no matter what.
