The Wharfedale Pro USX-800 Wireless Microphone System is a competitively priced, "True-Diversity" wireless system incorporating the latest advances in wireless microphone technology. The USX-800 incorporates a dual antenna UHF receiver with two identical tuners eliminating dropouts and unstable reception. The innovative Auto Frequency Scan function enables the system to automatically scan the UHF frequency band and select the strongest RF signals from the microphone's transmitter. By simply pressing the Sync button on the receiver, the user can automatically lock any of 50 available UHF frequencies between the transmitter and receiver. An infrared transmission link also feeds data to the hand-held transmitter providing up-to-date status of the signal strength, battery condition and selected transmission parameters.
