EMC-XLR 3-Pole Male Cable ConnectorThe EMC-XLR series is a specifically designed version of the XX series to provide better protection against radio frequency interference in critical applications in live performance and recording, where there are particular problems with the transmission of radio or mobile phones. The design ensures a continuous RF shield connection from the cable to the chassis connector housing via a circular capacitor around the cable shield. The circular capacitors act as a high-pass filter with a cutoff frequency around 10 MHz. An electromagnetic interference (EMI) suppression ferrite bead with 24 Ohm at 1 MHz between pin 1 and the cable shield provides a filter Improved low-pass for greater RF rejection.
