It is recommended that, where possible, all cables be good quality screened
twisted pairs with the screening braid connected to pin 1 on the XLR connector.
Optimum performance is obtained using double screened cable with separate ground
returns. It is also recommended that 360 degree connection be made to the screening
braid on the BNC connectors. Screened ‘D’ type connectors are also recommended.
