The UM1/77 Micro Diversity System is a high-performance UHF wireless system at prices that make sense for all kinds of video professionals. The UM1 Micro Diversity receiver operates on the 800 MHz frequency UHF band where there's much less RF interference. Truly compact, it mounts easily onto virtually any type of video camera using the supplied strip of Velcro. It can even be powered directly by the camera's own 12-volt power supply (if available), making it easy to integrate into any traveling or fixed installation video system.

Equipped with sophisticated circuitry for superior reception and crystal-clear audio, the UM1's wide range of features make it ideal for commercial videographers, corporate and broadcast video professionals. The unit includes a pair of tuned antennas and provides both balanced and unbalanced outputs (with three-position output level switch) and a headphone monitor output with continuously adjustable level control. The UM1 also features an audio peak LED, dual receiver indicators and an RF strength meter.

The UM1 is available in six different channels, all operating in the less crowded UHF bandwidth, so multiple UM1 systems (each tuned to a different channel) can be used in the same location without interference. The true diversity technology on this receiver also maximizes active range (up to 300 feet) and reduces potential interference problems through automatic switching between two independent receivers. Additionally, built-in companding noise reduction in all components ensures crystal-clear sound with minimized background noise and hiss.

The UM1/77 is available in a variety of configurations including, handheld systems, lavalier systems & headsets systems. Each system includes Samson's Concert 77 transmitters which feature pioneering technology to stabilize transmission.
