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 600 MHz frequency UHF band where there is much less RF interference. 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 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.
