EMI/RFI Shielded Starquad XLR3 Microphone Cable

$ 49.00 $ 59.00

For installations suffering from radio or electromagnetic interference, we recommend this special microphone cable. It is made from Gotham GAC-4/1 "Star Quad" microphone cable with double Reussen shielding, terminated using Neutrik NC3FXX and NC3MXX-EMC connectors.

These cables are 15' in length. (Custom lengths are available by special order.)

The cable jacket is black. The Neutrik XLR3 connectors are silver.

Gotham GAC-4/1 Features, according to the manufacturer:

The "Star-Quad" concept is known and recommended where the RF-rejection is the most important factor and where very long cable runs are needed. As we use each 2 conductors for low and high signal, we reduce the signal loss by 50% and due to the offset of the incoming RF-signal by the way the 4 conductors are twisted, the RF-rejection is over 130dB (25 kHz). The exclusive double shielding does its part of these features as well.

The Neutrik NC3MXX-EMC connector reduces susceptibility to cellphone and radio interference. According to Neutrik:

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 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.

It is worth noting that an upgraded cable cannot solve or prevent every EMI/RFI problem. Holding a live cellphone next to a condenser mic will usually create audible artifacts in the audio track, regardless of cable (or even microphone). Strong radio signals can couple directly into a microphone's circuit and/or capsule. In such cases, the only solution is to remove all transmitters -- whether Bluetooth, cell, or wifi -- from the studio.
