Electro-Voice RE420-RC3 Thread-On Condenser Microphone Head / Cardioid Pattern / Pop Filter / High-Pass

Description

The RE420-RC3 is a thread-on condenser microphone head designed to deliver clear and detailed vocal reproduction for wireless handheld transmitters. It uses a self-biased condenser element that emphasizes clarity and presence while maintaining a natural tonal balance. The design adapts mechanically and electrically to common 3-ring wireless transmitter couplings.

Key features include a cardioid polar pattern for focused pickup and improved isolation, a multi-stage pop filter to reduce breath blasts and plosives, and a selectable high-pass filter to cut unwanted low-frequency content. The internal shock mount reduces handling noise and vibration, preserving signal integrity during live use. The floating captured ID collar allows the branding orientation to be adjusted before final tightening.

Performance specifications include a frequency response of 50 Hz – 20 kHz, sensitivity of 5.6 mV/Pascal (-45 dBV/Pa), self-noise of 22 dB SPL A-weighted, and a maximum SPL of 137 dB (1% THD). The output impedance is 1000 ohms and the dynamic range is 115 dB, supporting clean signal capture across a broad level range. The capsule produces a warm low end, natural mids, and clear, detailed highs for vocal clarity on stage or in broadcast scenarios.

Connectivity and compatibility are straightforward: the head uses a 3-ring/3-pin electrical contact and a 1.25 in diameter 28 threaded coupling with UN-2A thread pitch to attach to common wireless handheld transmitters. It requires 4-8 VDC phantom power from the transmitter to operate the condenser element. The cardioid pattern provides optimal monitor placement at 180 degrees off-axis for maximum feedback rejection.

Typical applications include live vocal performance, broadcast and ENG environments, and any situation requiring an upgrade from a dynamic capsule to a condenser signature on compatible wireless transmitters. The RE420-RC3 preserves articulation and nuance while improving presence and intelligibility in mixes. It is useful where singers or presenters need expressive microphone technique and close working distance handling.

Installation is simple and fast – thread the head onto a compatible transmitter, orient the ID collar, and tighten to lock the orientation. The robust aluminum and steel construction and protective wire grille screen provide durability for touring and field use. Overall, the RE420-RC3 offers a reliable condenser option for professionals seeking improved vocal detail on standard wireless handheld transmitters.
