■ Speaker Connection Precautions
• You can connect speakers with an impedance of
between 4 and 16 ohms. If the impedance of any of
the connected speakers is 4 ohms or more, but less
than 6 ohms, be sure to set the minimum speaker
impedance to “4ohms” (➔ page 59). If you use
speakers with a lower impedance, and use the
amplifier at high volume levels for a long period of
time, the built-in protection circuit may be activated.
• Unnecessarily long, or very thin speaker cables may
affect the sound quality and should be avoided.
• Be careful not to short the positive and negative
wires. Doing so may damage the AV receiver.
• Make sure the metal core of the wire does not have
contact with the AV receiver’s rear panel. Doing so
may damage the AV receiver.
• Don’t connect more than one cable to each speaker
terminal. Doing so may damage the AV receiver.
• Don’t connect one speaker to several terminals.
Bi-amping the Front Speakers
Bi-amping provides improved bass and treble
performance.
When bi-amping is used, the AV receiver is able to
drive up to a 5.1 speaker system in the main room.
Perform bi-amping connections by using FRONT
terminals and SURROUND BACK or FRONT HIGH
terminals as shown below.
Once you’ve completed the bi-amping connections
and turned on the AV receiver, you must set the
speaker setting to enable bi-amping (➔ page 59).
Using Dipole Speakers
You can use dipole speakers for the surround and
surround back speakers. Dipole speakers output the
same sound in two directions.
Dipole speakers typically have an arrow printed on
them to indicate how they should be positioned. The
surround dipole speakers (a) should be positioned so
that their arrows point toward the TV/screen, while
the surround back dipole speakers (b) should be
positioned so that their arrows point toward each
other, as shown.
Important:
• When making the bi-amping connections, be sure to
remove the jumper bars that link the speakers’ tweeter
(high) and woofer (low) terminals.
• Bi-amping can be used only with speakers that support
bi-amping. Refer to your speaker manual.
