This Sommer Cable SC-Onyx 2008, is a reasonably good quality twin core figure of eight screened audio cable. It appears to be designed for use on internal patchbay connection wiring duties , or for very light home use, such as making up bespoke headphone extensions or other general home or home studio audio patch cable type duties. It is not heavy enough to use within an open stage or road environment in my humble opinion. But more than adequate for stage or studio use on internal equipment wiring where it’s never exposed to the outside world.
Each core is very easy to strip down to the copper, it tins very easily and solders very well. Each core is in addition individually screened and also colour coded (red and yellow) for ease of use. Once in use it’s relatively low noise even in high gain areas and doesn’t kink or twist easily, basically it does exactly what you would expect a cable like this to do, at a very reasonable price.
