how to install Electro-Voice Lapel System

Setting up the Electro-Voice Lapel System is a straightforward process that can be completed in a few simple steps. Begin by unpacking the BP-300 transmitter, the ULM18 directional lavalier microphone, and the receiver unit. Ensure you have fresh AA batteries for the transmitter, as this will help guarantee reliable operation throughout your event.

Install the batteries in the BP-300 transmitter following the orientation markings, then mount the transmitter on the talent or an easy-to-reach clip on a belt or waistband. Attach the ULM18 lavalier microphone to the talent’s lapel using the provided clip, keeping the microphone cable secure and away from clothing that could rub against the capsule. Position the microphone at chest level, approximately 6 to 8 inches below the singer or speaker’s chin for optimal proximity effect and natural voice capture. Connect the lavalier mic to the transmitter, turning on the unit and verifying the signal is solid.

On the receiving side, connect the receiver’s output to your mixer, audio interface, or camera, and power it up. Use the receiver’s controls to select a clean, interference-free channel. If the system features automatic frequency scanning, engage this function to locate the best available channel automatically. Once the transmitter and receiver are paired, perform a quick test by speaking into the microphone at the intended distance and adjusting the transmit gain on the BP-300 if needed. Conduct a brief sound check to confirm consistent level, natural tone, and comfortable headroom. Finally, secure all cables, place the receiver where it won’t be bumped, and remind the talent to speak toward the microphone for optimum pickup.

Maintenance and best practices include keeping batteries fresh, avoiding excessive bending of the lavalier cable, using the windscreen during outdoor use to reduce wind noise, and performing periodic checks of the signal during rehearsals to anticipate any potential interference problems. With proper positioning and care, the Electro-Voice Lapel System delivers dependable, high-quality wireless audio for demanding productions.
