TERRA TV-modulaattori MT-47

The TERRA TV Modulator MT-47 is a professional-grade RF modulator designed for distributing audio and video signals over coaxial cable networks. It converts composite video and stereo audio inputs into a PAL-modulated RF output, covering VHF and UHF bands from 47 to 862 MHz. Ideal for CCTV, MATV, and small-scale broadcasting applications, this unit features quartz-stabilized frequency control, a built-in test pattern generator, and an antenna loop-through for easy integration.

Advantages

Quartz-stabilized frequency control ensures stable, drift-free operation. The microprocessor-controlled interface with LED display and buttons allows easy channel selection and setup. The built-in test pattern generator simplifies installation and troubleshooting. Antenna loop-through enables daisy-chaining multiple modulators or connecting to an existing antenna system.

Suitable for

• Distributing TV signals in hotels, hospitals, schools, and commercial buildings
• CCTV video distribution over coaxial cable
• Small-scale broadcasting and head-end systems
• Adding local video sources (e.g., cameras, media players) to an RF distribution network
