'D-Type' Connections

This product relies on the use of screened cables for connection to the 15 way 'D-Type' ports.
The cables must have the foil or braid screen connected effectively to the metal headshell to
ensure continued compliance. The following headshells provide suitable screen connection
and are available from Black Box:

It is important to keep the screen to shell connection as short as possible.
