Audio Precision Portable One Plus Access - Unbalanced Connections

Unbalanced Connections
Many devices use unbalanced connectors, such as the RCA (phono)
connector, the BNC, or the 1/4" Phone jack.
When connecting an unbalanced device, it is recommended that
2-conductor shielded cable be used. This offers higher immunity to
noise and interference than single-conductor cable. The following
diagram shows the preferred cable connections.
