Electro-Voice R300-L Wireless Lavalier Microphone System

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's 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'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.

About Lavalier Microphones at Sound Productions

Lavalier microphones are miniature mics specifically engineered for capturing audio discreetly, while providing hands-free operation and flexibility of movement. Lav mics are also called lavs, lapel mics, clip mics, body mics, collar mics, neck mics, or personal mics. A great choice for stage use, their low-profile design also makes it easy to keep your audience’s focus on your performance.

Popular in TV, theater, interviews, and stage environments such as houses of worship or lecture halls, lavalier microphones are ideal for applications where you need hands-free versatility while maintaining optimal sound quality. Easy to camouflage, lavs are generally attached on or beneath clothing and can be clipped into hair for a virtually invisible mic placement for actors, singers, public speakers, and more. With options that are built to resist water, sweat, and makeup, lavalier mics are designed to deliver the quality and reliability you require, day after day.

Give your vocals great scope in a small package with lavalier microphones from Sound Productions. Lightweight and flexible, headworn mics come in a wide range of styles, polar patterns, and offer a variety of accessories to ensure you find the model that best fits your needs. Choose between an earset option (which rests on one ear) or a headset (which rests on both) for a secure, comfortable fit.
