Neutrik NC3FXX-EMC 3-Pole Female EMC-XLR Cable Connector

The Neutrik NC3FXX-EMC adds extra RF screening to a 3-pole female XLR cable connector, for live and recording work where radio transmissions or cell phones cause interference.

It is a version of Neutrik’s XX series cable connector. A circular capacitor around the cable shield keeps an unbroken RF shield connection from the cable to the housing of the chassis connector. The capacitor works as a high-pass filter with a cutoff around 10 MHz, and because the shield has no low-frequency connection to ground, ground loops are easier to avoid. A ferrite bead of 24 ohms at 1 MHz between pin 1 and the cable screen adds a low-pass filter for better RF rejection.

A circumferential ground spring makes an accurate connection to the mating shell. The shell is nickel-plated zinc diecast, a chuck-type strain relief clamps the cable securely, and a boot with a rubber gland protects it from bending stress. The gold-plated solder contacts take wire up to 0.75 mm² (20 AWG), and the connector takes cable from 3.5 to 8.0 mm across.
