The Neutrik NC3MXX-EMC 3-Pole Male EMC-XLR Cable Connector is a specially designed version of the XX series that provides enhanced RF screening for critical applications in live performance and recording where particular problems with radio transmission or mobile phones exist. 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 capacitor acts as a high-pass filter with a cut-off frequency around 10 MHz.
An EMI suppression ferrite bead with 24 ohm at 1 MHz between pin 1 and the cable screen provides a low-pass filter for improved RF rejection.
Key Features
- 3-pole male and female XLR cable connector with integrated capacitive shield to shell connection
- Design ensures a continuous RF-shield connection but avoids ground loops (no LF-shield connection)
- Circular capacitor around the cable shield enables low-inductive shield connection to connector housing
- Cable shield - Pin 1 connection includes EMI suppression bead to block high frequencies
- Rugged zinc diecast shell, long lasting and durable
- Chuck-type strain relief system for secure clamping of cables
- Boot with rubber gland gives high protection against bending stresses
