Balanced And Unbalanced Connections - Yamaha M-5000 Owner's Manual

Balanced and unbalanced
connections
This unit features balanced input jacks (BAL) and
unbalanced input jacks (LINE).
NOTICE
Do not use balanced and unbalanced connections between
two components simultaneously . Doing so would create a
ground loop that could generate static and noise .
Balanced connection
A balanced connection is a great advantage against
external noise. For a balanced connection, use a cable
with male XLR connectors. When connecting a cable, be
sure to align the pins on the connector with the holes on
the jack, and then insert the connector into the jack until
you hear a click. To remove the cable, while pressing
and holding down the lever on the BAL jack, pull out the
male XLR connector from the jack.
When making a balanced connection, you must set the
polarity correctly. To set the polarity, use the PHASE
selector on the rear panel.
