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.
