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 cable to the chassis connector housing via a circular capacitor around the cable shield. The circular capacitors act as high-pass filter with a cut-off frequency around 10MHz. An EMI suppression ferrite bead with 24ohm at 1 MHz between pin 1 and the cable screen provides a low-pass filter for improved RF rejection.
