The BodyMics Expansion Pack takes your audio experience to new heights. Each feature serves to further enhance your audio experience. Paddle antennas deliver an improved wireless signal reception and reject RF signals outside the coverage area for crystal-clear audio, which is ideal for large venues (distances over 50 ft). Our rechargeable batteries, plus one 16 way battery charger, ensure that your system will always power-on. Finally, the transmitter belts, face tape, and variety of microphone clips help better secure the transmitters to your performers, facilitating high-quality sound. Take advantage of this addition to your audio rental for an unforgettable audio experience!
