ElectroVoice R300E

The Electro-Voice R300-E is a UHF headworn wireless microphone system that gives presenters, fitness instructors, and worship leaders hands-free freedom with consistent sound. It pairs the metal BP-300 bodypack transmitter with EV’s HM3 omnidirectional headset microphone, and the true diversity receiver uses ClearScan to find a clear channel automatically.

Highlights

• BP-300 metal bodypack transmitter
• HM3 omnidirectional headworn microphone
• 32 channels per band with ClearScan; up to 8 systems simultaneously
• True antenna diversity receiver
• Tone-code and amplitude squelch to block stray noise
• Up to 14 hours of operation on two AA alkaline batteries; Band C (516-532 MHz)

Electro-Voice R300-E: Hands-Free, Consistent Sound

A headworn microphone keeps the capsule at the same distance from the mouth no matter how the speaker moves, which means consistent level and clear speech throughout a presentation, workout class, or sermon. The HM3’s omnidirectional pickup sounds natural and forgiving of placement, and the BP-300’s metal bodypack stands up to daily use.

ClearScan makes setup simple: the receiver scans the band and selects the clearest channel, then you sync the transmitter and you’re ready.

Reliable Wireless for Daily Use

True antenna diversity reduces dropouts as the presenter moves around the room, and tone-code squelch keeps the receiver muted when its transmitter is off, preventing bursts of noise. Up to 14 hours of battery life on two AA cells covers long days of classes, services, or meetings.

Setting Up the R300-E

Fit the HM3 headset so the capsule sits near the corner of the mouth, just out of the breath stream. Clip the bodypack to a belt or waistband and route the cable behind the head and down the back. Place the receiver with a clear line of sight to the speaking area, connect it to your mixer, and run ClearScan before each event.

What to Pair With the R300-E

Pair the R300-E with a mixer or powered speaker, rechargeable or spare AA batteries, and replacement headset windscreens. For rooms with multiple presenters, combine it with R300-HD handheld and R300-L lavalier systems, using ClearScan to coordinate channels.

Omnidirectional Headsets in Loud Rooms

Omnidirectional headsets sound natural and are easy to position, but because they pick up sound from all directions, keep loudspeakers in front of the presenter and avoid pointing stage monitors directly at them. Close placement near the mouth gives the best signal-to-noise ratio and the most gain before feedback.

Headset vs. Lavalier: Which Is Right?

A lavalier clips to clothing and is nearly invisible, but its level changes as the presenter turns their head, and it sits farther from the mouth, so it gives less gain before feedback. A headset like the R300-E keeps the microphone at a fixed distance from the mouth, so the sound stays more consistent and louder in the mix. That makes the headset the better choice for active presenters, fitness classes, and rooms with loud PA systems.

Electro-Voice R300-E FAQ

Is the HM3 headset cardioid or omnidirectional? The HM3 is omnidirectional, for natural sound that is forgiving of placement.

How many systems can I run together? Up to 8 systems simultaneously per band, using ClearScan to select compatible channels.
