The R300-L is a robust UHF wireless bodypack system, suitable for any application where the convenience of a wireless lavalier microphone is required. The system BP-300 rugged metal bodypack transmitter is simple to use, and is powered by two AA batteries. Included with the system, the ULM18 is a high quality directional (cardioid) condenser lavalier microphone suitable for sound reinforcement or recording of voice, and allows users the convenience of a hands-free presentation or performance experience. Exceptionally useful for sound reinforcement applications, the ULM18’s directional cardioid polar pattern reduces sound system feedback potential when used properly. The receiver 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.
