The Harris® Multi-System Controller (MSC) is engineered to ensure your television or radio broadcast is seamless—even in the event of transmitter failure. This next-generation multi-system control platform extends the redundancy capabilities of Harris transmitters to both new and legacy transmitter platforms—the first system on the market that integrates legacy transmitters into N+1 systems.*
The MSC incorporates the latest advances in technology, reflecting the Harris commitment to innovation and history as the industry-leading provider of redundancy solutions for television and radio transmitters.

Cost-effective, Reliable, Flexible
At Harris, we know on-air time is critical. For that reason, the Multi-System Controller is designed to maximize on-air reliability for broadcasters with digital networks, and can be configured across various applications—main/alternate, N+1 and dual transmitter systems.
As an N+1 controller, the MSC is a cost-effective, reliable backup system with a simple-to-use interface, making it ideal for larger network operators with multiple transmitters at each site. As a dual transmitter system controller, the MSC enables increased power capability, operational flexibility, and reliability by combining two or more transmitters.
How it Works
The MSC monitors the operating status and parameters of the main transmitters and keeps the +1 reserve in standby. When the MSC detects a failure, it safely disables the main transmitter and activates the standby transmitter.
Users have the option of monitoring and controlling the MSC though the front-panel push-button controls with an alpha-numeric display, or remotely via a web browser or optional, parallel I/O.
In N+1 applications, the MSC monitors and controls each main or N transmitter. If the MSC detects RF output or other failure output that exceeds the user’s configured time delay, it automatically sets the frequency of the reserve or +1 transmitter to that of the failed main transmitter. It then routes the correct video/audio to the reserve, changes the configuration of the RF switching system to place the reserve transmitter on air, and turns it on. The failed main transmitter‘s RF output is simultaneously routed to the dummy load, where it can be tested and repaired without further broadcast interruptions.
If a second main transmitter fails, the reserve will back up the highest-priority transmitter.
The MSC is designed specifically for Harris transmission products, including Maxiva™ UHF (ULX and UAX) DTV transmitters, Platinum™ VHF (VLX and VAX ) DTV transmitters and Platinum Z, ZX® and HPX® FM and HD Radio™* transmitters. With an optional I/O module, the MSC also works with most legacy and other vendors’ transmitters in N+1 systems.
