The ALTO wireless microphone system AU-800R/800H/800P series is the delicately designed UHF, PLL
synthesized system, with two antennas built inside the receiver for smart switching diversity control, the
higher level RF signals may be fed into the system for greater reliability and coverage, therefore, the risks of
breakdown and interference are to be effectively reduced. By the Auto Scan function provided by the
AU-800R, PLL UHF Diversity Receiver, the operating frequency of the transmitter may be automatically
searched out and locked by the system. Or, you can manually adjust the channel of the transmitter to match
the receiver in case you know about the operating frequency of it. Generally, the AU-800R/800H/800P series
consists of
-AU-800R, PLL UHF Diversity Receiver
-AU-800H, Handheld transmitter
-AU-800P, Body Pack transmitter
