The Electro-Voice R300-E is a wireless headworn microphone system designed to deliver reliable hands-free vocal pickup in small to medium AV environments. It pairs an omnidirectional headworn mic with a bodypack transmitter and a single-channel tabletop receiver to provide clear speech and consistent levels. The system targets presenters and performers who need dependable wireless audio with simple setup and long battery life. Key features include an omnidirectional HM3 headworn condenser microphone, BP-300 bodypack transmitter, and an R300 antenna-diversity tabletop receiver. The receiver offers 32 pre-programmed frequencies and ClearScan to locate the clearest channel automatically. EZ Sync transfers the selected channel to the transmitter via infrared to simplify channel matching. Performance specifications include analog UHF operation in Band C (516 to 532 MHz), up to 150 ft line-of-sight operating range, and a dynamic range greater than 95 dB. The transmitter provides up to 8 mW RF output and up to 14 hours of operation on two AA batteries. Frequency response characteristics cover the vocal range with receiver response around 80 Hz to 18 kHz and microphone response from 50 Hz to 20 kHz. Connectivity includes XLR balanced mic output and 1/4" TS unbalanced line output on the receiver to support mixers and powered speakers. The receiver uses two removable TNC 1/2 wave antennas and supports antenna-diversity reception to reduce dropouts. The transmitter uses a 4-pin TA4M mini-XLR input for the headset mic and synchronizes channels via IR. The R300-E suits presentations, lectures, AV installations, and stage applications where a discreet headworn mic and reliable wireless link are required. Multiple compatible groups of eight channels allow up to eight simultaneous systems in one band. The system is compact enough for tabletop use and can be rackmounted with optional ears and antenna cables. Build quality emphasizes a metal receiver chassis and a rugged metal bodypack transmitter with a backlit LCD and battery gauge. Two removable half-wave antennas and included universal power adapter support flexible deployment. The included soft carry case and foam windscreen help protect gear during transport and use.
