The R300-L Wireless System from Electro-Voice features the convenient ULM-18 Uni-directional lapel lavalier.

Unique features like One-Touch ClearScan and EZsync make the R300 quicker and easier to set up and use than any other similarly priced wireless system, while its rack-mountable metal receiver, sturdy metal bodypack and handheld transmitters, and remote-mountable antennas are of a build and performance quality usually reserved for the highest-end professional products. This combination of value, professional features, and road-ready ruggedness make the R300 a perfect choice for a wide range of wireless applications, from live vocals and instruments to professional presentations.

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. 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.

Great Construction & Features, Bad Sound


Used this wireless system during a wedding ceremony. It was a clear day, mildly windy, and we were about 50 feet from the Pastor who had the transmitter. We pinned the lapel to the inside of his jacket (to shield the wind) and placed the transmitter in his back pocket. We had a direct line of sight from transmitter to receiver. This unit has great features and is built to last. Unfortunately, the audio quality sounded like a tin can. The audio was crystal clear, but acoustically speaking, it seems to be missing the low end frequency and sounds as if the person speaking is in a tunnel made of aluminum. Other than the sound not being to my taste, this is a quality unit. If it sounded better, I would have kept it. The ClearScan function, A/B antenna switching, and transmitter sync work great! The only reason why I cannot recommend this unit is because of the audio....other than that, range, construction, features are truly impressive.
