The EMC-XLR Series is a specifically designed version of the XX series to give enhanced RF screening for critical applications in live performance and recording where there are particular problems with radio transmission or mobile phones. The design guarantees a continuous RF shield connection from the connector to the mating connector housing via a circular capacitor around the cable shield. An EMI suppression ferrite bead between pin 1 and the cable screen provides a low-pass filter for improved RF rejection. A circumferential ground spring provides an excellent connection to the mating connector shell. Ground loops are avoided as there is no LF connection between screen and ground.
This special version of the EMC-XLR is effectively the cable connector with a D-series flange to enable it to be mounted into a panel. It has the same specifications as the NC3FXX-EMC, and also includes the locking-nut feature of the NC3FX-Spec for secure fastening of a gooseneck, for example.
For larger panel-openings an additional round-flange, FDR1, with a diameter of 63.5mm is available (mounting screws included).
