The R300-HD is a robust handheld UHF wireless system, suitable for any application where the convenience of a handheld transmitter is required. The HT-300 metal handheld transmitter is made to withstand the rigors of daily use while remaining comfortable and light-weight in your hand. The PL22 dynamic microphone is the perfect all-around microphone for singing, speaking engagements, and emcees. The cardioid pickup pattern rejects sounds from the surroundings, helps control audio feedback, and still allows an experienced vocalist to work the microphone. 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.
