The R300-E is a robust UHF wireless bodypack system, suitable for any application where the convenience of a wireless headworn microphone is required. The system's BP-300 rugged metal bodypack transmitter is simple to use, and is powered by two AA batteries. The system's light-weight, double-ear hook HM3 headworn microphone is comfortable for extended daily use, and provides the user the convenience of hands-free presentations or performances. The receiver's dual antenna diversity helps avoid signal dropouts, and its durable metal frame and chassis can either be used on a tabletop, or rack-mounted with optional rack mounting hardware.
