Audio Precision ATS-1 Access - Unbalanced Connections with the XLR Connector Panel

Unbalanced Connections with the XLR Connector Panel
Many devices use unbalanced connectors, such as the RCA (phono)
connector, the BNC, or the 1/4" Phone jack.
When connecting an unbalanced device with the XLR connector
panel, it is recommended that two-conductor shielded cable be used.
This offers higher immunity to noise and interference than
single-conductor cable. Figure 3-18 shows the preferred cable
connections. The generator should be set to an unbalanced
configuration by selecting 50 Ω Unbal on the Generator panel.
