is similar in design and quality to the TRICONE MKII, but a little thinner due to the twin construction. It is well-suited for manufacturing hifi cables, adapters and for permanent installation. And it fits nearly all jack and RCA connectors. The SC-Onyx 2008 can be spliced at the centre of the cable. Each wire has its own helical copper mesh screen plus a thick jacket. The insulation is marked in white and yellow. The SC-Onyx 2008 is very small in diameter which makes it ideal for fitting mini jack connectors.
