Balanced and unbalanced
connections
This unit features XLR-type balanced jacks and RCA-
type unbalanced input jacks.
Note
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 designed to cancel and prevent
unwanted noise. Since longer cables tend to pick up
more noise, a balanced connection is useful if you need
to use long cables. Generally, if your components feature
balanced outputs, you should use balanced connections.
Jacks for balanced connections
XLR-type jacks on this unit are used for balanced
connections. The input and output jacks utilize different
designs. Input jacks are female, and output jacks are
male. For balanced connections, balanced cables with
XLR connectors are used. Connect a male connector
on the cable to a female jack on the unit, and connect a
female connector to a male jack on the unit.

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 female XLR connector, pull it out
from the jack.
Balanced connection polarity
When making a balanced connection, you must set the
polarity correctly. Generally, pin #2 is Hot, but sometimes
pin #3 can be Hot. Refer to the owner's manual for the
connected component to learn which pin at the output
jack is Hot.
To set the polarity for the BAL 1 and BAL 2 input jack
pins, use the PHASE selector on the rear panel.
Note
• The PHONO and EXT . IN jacks do not feature a PHASE
switch . The pin polarity of these jacks is standard and
fixed .
• Pin #2 is Hot on Yamaha players .
