Roland Gold Series Quad microphone cables are crafted with an additional pair of OFC (oxygen-free copper) conductors to provide ultra-pure signal transmission and superior noise reduction. This studio- level configuration uses four conductors to cancel out noise and reject RF and EM interference that may be present with wireless systems or other electronics. Additional high-quality components such as Neutrik gold-plated connectors provide the cleanest, most precise sound reproduction available. Roland Gold Series cables are engineered to transmit the finest audio details with extreme accuracy, ensuring that you get out exactly what you put in.
