The EWI MQN Pro Quad XLR cable is a twisted
pair premium mic cable with Neutrik XX Series cord ends. This is a
really nice 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.
