Connect it SI

Cable without "sound"

Signal cables optimised for use with turntables. Highly flexible with low capacitance and perfect shield. These cables were developed to have low colouration and are handmade in Europe. “State-of-the-Art” components for leads, dielectric and plugs were chosen after intense listening tests. Specific lengths were chosen because of their significant advantages when carrying audio signals. Three quality levels are available (SI / CC / C).

Compared to gold, silver has superior conductivity. However, silver contacts may oxidise, but this does not affect quality as silver oxide is still an excellent conducter. These silver contacts and silver conductors make Pro-Ject Connect it SI cables stand out in their price class.

As the Connect it SI cable is a parallel symmetrical cable the shield is only connected on one end. The blue mark indicates this side. The marked side should always be connected to the receiving end (i.e. phono stage or amplifier).
