Elite Core CSM4
Elite Core's CSM4 Studio Quad Custom Shop mic cables are hand-built by skilled technicians in their 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. Every detail - the cable construction, the connector choice, the solder, the flux, the shrink tube, the testing, and the packaging, are each carefully chosen to create the finest stage and touring microphone cable available.
The CSM4 quad conductor cable is designed from the inside out to be the finest studio and stage grade cable available. Every component of the cable itself is carefully chosen with the end goal of creating a tough, flexible, and dead-quiet microphone cable. It's not an ordinary cable. Here's a closer look:
There are four cores that are very tightly twisted with a very short lay length. Each core is constructed of 26 strands of .1 pure bare copper. These conductors are transparent, precise, and extremely flexible. The high twist rate of these four conductors around each other results in dramatically improved rejection of electromagnetic interference when compared to standard two conductor mic cables. In some cases, the noise reduction could be up to 20db.
Inner Conductor Insulators
The insulator that was chosen to separate the four inner conductor cores is cross linked polyethylene, or XLPE. This insulator is a thermosetting compound made from a polymer resin that has been irreversibly cured to form a special type of insulator that is less prone to shrinking when heated. Elite Core chose XLPE over the less expensive old-fashioned PVC because it has much lower dielectric loss and, despite its smaller diameter, is easier to solder without shrinkage. PVC certainly would have been cheaper. They weren't trying to build the world's cheapest cable, they set out to build the best. With careful attention to their selection of soldering equipment and the temperature and methods used to solder, the XLPE was the obvious choice for their quad conductor CSM4. Elite Core selected two blue and two white for the four insulators.
CSM4 cables are hand terminated on Elite Core's Custom Shop with Genuine Neutrik XX series connectors. Their standard is the black connectors with silver contacts. The XX series is the next generation of the worldwide accepted standard of XLR cable connectors. The successor of the X series offers several new features which make it more reliable, easier to assemble and improves contact integrity as well cable strain relief.
