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. Rack mount kits and front mount antenna cables are available for the R300 for a professional installation. For applications with up to 4 receivers in one rack, the APD4+ antenna splitter can provide antenna and power feeds.

BP-300 is an all new metal bodypack transmitter that is rugged, compact, and easy to use. Using two AA batteries for 14 hours of use, the BP-300 is one of the most economical transmitters around for applications that require daily operation. The mute function keeps the RF signal live while it mutes the audio to protect your channel and prevent noise in the audio system. The TA4 connector allows the use of any EV lapel or headworn microphone for a variety of applications. The receiver for the R300 system is equally at home on a table top or in a 19 inch equipment rack.

  • ClearScan automatically finds the clearest channel.
  • EZsync one-step channel setup.
  • HM3 omni-directional microphone.
