Electro-Voice ND76-RC3 - ​​Cardioid Dynamic Microphone Head for Wireless Transmitters (1.25″-28 Thread, 3-Ring/3-Pin)

The Electro-Voice ND76-RC3 is a threaded microphone head featuring a large-diaphragm cardioid dynamic capsule, designed to mount on wireless handheld transmitters using the 1.25″ diameter × 28 threaded , 3-ring / 3-pin contact fitting. It delivers a clear, balanced, and presentable voice with excellent stage sound isolation and high gain before feedback , making it a versatile choice for vocalists, broadcasters, and live productions.

It features an advanced shock mount (4-point perimeter suspension + pneumatic pump) that reduces handling noise, an ultra-dent-resistant Memraflex grille , a hydrophobic membrane that protects the cartridge from moisture and dirt, and a humbucking coil to attenuate interference-induced hum. A floating ID collar allows the marking to align with the transmitter body when tightening the screw for a clean, professional finish.
