Connecting the AV receiver
Speaker Configuration
For 7.1-channel surround-sound playback, you need
seven speakers and a powered subwoofer.
The following table shows which channels you should
use based on the number of speakers you have.
* If you’re using only one surround back speaker, connect it to the
power amplifier’s left terminals.
No matter how many speakers you use, a powered
subwoofer is recommended for a powerful and solid
bass. If you use surround back speakers, another power
amplifier is necessary (page 18).
To get the best from your surround-sound system, you
must set the speaker settings. You can do this
automatically (see page 35) or manually (see page 61).
Attaching the Speaker Labels
The AV receiver’s positive (+) speaker terminals are all
red. (The negative (–) speaker terminals are all black.)
The supplied speaker labels are color-coded and you
should attach them to the positive (+) side of each
speaker cable in accordance with the above table. All
you need to do then is to match the color of each label to
the corresponding speaker terminal.
• If you are using banana plugs, tighten the speaker
terminal before inserting the banana plug.
Using Dipole Speakers
You can use dipole speakers for the surround left and
right and surround back left and right 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
left and right dipole speakers should be positioned so that
their arrows point toward your TV or screen, while the
surround back left and right dipolar speakers should be
positioned so that their arrows point toward each other, as
shown.
If you use surround back speakers, another power
amplifier is necessary (page 18).
Connecting a Powered Subwoofer
Using a suitable cable, connect the AV receiver’s PRE
OUT: SUBWOOFER to the input on your powered
subwoofer. If your subwoofer is unpowered and you’re
using an external amplifier, connect the PRE OUT:
SUBWOOFER to the amp’s input. You can connect the
powered subwoofer with two SUBWOOFER PREOUT
jacks respectively. The same signal is output from each
jack.
