Electro-Voice RE3-ACC-OL3 - Omnidirectional Lavalier Microphone with TA4F Connector for RE3 Systems

The Electro-Voice RE3-ACC-OL3 is an autopol electret condenser omnidirectional lavalier microphone designed to deliver clear, natural vocals in presentations, lectures, houses of worship, education, and video content. Its low-profile design minimizes clutter on camera and on stage, and the omni pattern prevents proximity effect and maintains a consistent level even when the speaker turns their head. It connects directly to RE3-BPT bodypacks and other EV transmitters to the same standard via the TA4F mini-XLR connector.

It offers a frequency response of 60 Hz to 15 kHz , sensitivity of 17.5 mV/Pa (−35 dBV/Pa) and support up to 130 dB SPL , figures optimized for speech and voice. The capsule operates on 3–9 V DC power (plug-in power from the bodypack) and has an impedance of 2.2 kΩ . The set includes a clothing clip and a foam windscreen to reduce wind noise and plosives. 1.45 m fixed cable, non-reflective black finish and brass construction with a steel mesh grille for maximum durability.

Product benefits

• Natural and homogeneous voice without level variations when moving the head.
• Immediate integration with RE3 systems via TA4F and power supply from the beltpack.
• Discretion on stage and in camera thanks to its compact capsule and anti-reflective finish.
• Professional robustness (brass + steel mesh) for intensive use on tours and installations.

Use cases

• Corporate presentations, education, and conferences with full mobility.
• Places of worship and events where speech intelligibility is paramount.
• Video production, interviews, and streaming with low-visibility microphones.

Frequently Asked Questions

• Is it a dynamic microphone? No. It's an electret condenser microphone and requires 3–9 V DC from the bodypack.
• Can I connect it directly to an XLR? Not directly. It's designed for TA4F bodypacks that provide the proper polarization.
• Does it include accessories? Yes, a clothespin and foam windscreen .
