Wiring Reference
Unbalanced Connections:
Unbalanced out to balanced in
The RCA connector and the 1/4” TS connector are
unbalanced connectors. However, the wiring differs
depending on if they are sending to, or receiving from a
balanced connector.
In this example, the unbalanced connector is sending signal
to a balanced connector. When wiring this connection,
use a shielded twisted pair cable. The balanced side wires
the same as a standard, balanced connection. On the
unbalanced side, you wire the white (minus) wire together
with the ground. This provides some common mode rejection
at the balanced input.
Unbalanced Connections:
Balanced out to unbalanced in
When your output requires a balanced connector, but you
are sending signal to an unbalanced input, the rules change.
Use a single strand shielded wire. Wire only to the plus and
ground terminals of what would the typically be the balanced
connector.
