Description
The EWI MBQB Pro Quad XLR cable is a twisted pair premium mic cable, suitable for high performance professional applications.
Twisted pair mic cables are preferred by professionals for their enhanced noise rejection and reliability due to the redundancy of the paired wiring. Instead of only having two conductors and a shield, like regular mic cables, twisted pair mic cables such as these actually have four conductors and a shield. There are two conductors wired to each of the signal connectors (pins 2 and 3). Therefore, pin 2 and pin 3 have two wires each attached, with one wire from each pin paired and twisted the length of the conductor with the wires from the other hot pin The theory is that twisting each wire the length of the conductor with a wire from the other pin allows so that any noise that is induced in one wire is induced in a paired wire from the other hot pin. Since the induced noise in both conductors will hit the transformer at the same time, the two signals will cancel, and the noise will not be transferred down the signal chain. Besides all of that, since there are two conductors for each signal, if one wire fails, the cord will still work (maybe a little noisier, but it will still function)! The 4 ea. 22 gauge signal conductors are extremely high purity 99.98% annealed copper. The braided shield is also tinned 99.98% copper tightly braided to give 98% coverage, which is some of the highest braid coverage available. The Super Flexible Innocuous Neoprene PVC (SFIN PVC) resists tangles and stays flexible yet extremely durable over a wide range of temperatures. The MBQB series are stock equipped with EWI ES3FB and ES3MB XLR three pin XLR ends, which are fully compatible with standard XLR connections. The XLR ends are a black anodized cast zinc shell with gold contacts, and are hand soldered with good strain relief. The grip and strain relief are very good on these durable cord ends.
