Inner Conductors:
The two primary stranded inner conductors each have 20 strands of 0.12 bare copper. While many cable companies will lower cost by using inferior materials here (like aluminum with a copper coating), Elite Core CSM is pure, from the inside out. And you can hear the difference.
Inner Conductor Insulators
The insulator that was chosen to separate the two inner conductor cores is Polyethylene, or PE. This insulator is a part of a class of polymers known as polyolefins. We chose PE over the less expensive old-fashioned PVC because it has the lowest dielectric loss and highest initial dielectric strength of all thermoplastic insulators. PVC would have been cheaper. We weren’t trying to build the world’s cheapest cable, we set out to build the best. XLPE, while it is more resistant to high heat, has more dielectric loss than PE. With careful attention to our selection of soldering equipment and the temperature and methods used to solder, the PE was the obvious choice because of its extremely low dielectric loss characteristic. The PE is firm, strips well, and maintains a constant diameter with ease. We selected a red and a white color for the two insulators.
Conductive PE Layer:
The magic of the CSM2 cable is found on the outside of the red and black inner cores. It’s a refined thin layer of conductive PE. Yes, that’s right, it’s a layer of thermoplastic polyethylene that has been precisely blended with carbon fiber to create a conductive layer that is perfectly snug around the red and white inner cores. This layer is key to the CSM2 cable. These days, there is an extreme amount wireless noise (from wireless mics, IEM transmitters, wireless DMX devices), electromagnetic noise (from power cables, lighting ballasts and moving light motors), and just plain abuse (from people and casters!) in the world of entertainment sound, lighting and video. The CSM2 cable provides an extra layer of shielding with the conductive PE. This layer serves three purposes. When selecting your cable, it’s important to consider whether these three issues are some that you deal with.
Soft Cotton Stranded Filler:
To create the soft, pleasing feel of the CSM2 cable, we chose a natural cotton filler to round out the interior of the cable. It feels right, coils the way you want it to, and is pleasant to handle.
Helical Bare Copper Shield
The primary helical shield is provided by 80 strands of 0.1 the highest quality bare copper. It’s soft, flexible, and effective in shielding from EMI and RF noise. With the combination of this quality spiraled shield plus the two conductive PE coatings on the inner conductors, the CSM2 is the perfect cable for today’s active and noisy stages. The sounds and signals you want to stay inside are contained, and the noise and interference that you want to keep out is reflected away from your precious audio.
Outer Jacket:
The outer jacket of the CSM2 cable is opaque black PVC with an outside diameter of 6.5mm. PVC is the perfect material for this application because it holds its shape well and has great abrasion resistance. It’s easy to clean and comfortable to coil.
