The Elite Core CSM4 is a stage grade ultra quiet and ultra durable quad microphone cable. This Studio mic cable is hand-built by skilled technicians in our facility in Conway, Arkansas, USA. A good quad cable is advised in any stage or studio setting with high levels of RF and EMI noise, especially in today’s wireless world. Quad cables use double conductors and are far more effective than standard balanced cables in canceling noise that can creep past even the best shield. Only the finest available materials and most effective techniques are used.
