Second Zone speaker B setup

Caution
• Before making or changing the connections, switch off
the power and disconnect the power cord from the
power outlet. Plugging in components should be the
last connection you make with your system.
• Be careful not to allow any contact between speaker
wires from different terminals.
• You can use speakers with a nominal impedance
between 6 Ω to 16 Ω (please see Switching the
speaker impedance on page 69 if you plan to use
speakers with an impedance of less than 8 Ω).
After selecting 2nd Zone in Surround back speaker
setting on page 37, you can use the speakers connected
to the (surround back) B speaker terminals on the rear
panel to listen to stereo playback in another room. See
Switching the speaker system below for the listening
options with this setup.
1 Connect a pair of speakers to the surround back
speaker terminals on the rear panel.
Connect them the same way you connected your
speakers in Installing your speaker system on page 17.
Make sure to review Placing the speakers on page 18
when placing the speakers in another room.
2 Select '2nd Zone' from the 'Surr Back System' menu.
See Surround back speaker setting on page 37 to do this.

Switching the speaker system

If you selected 2nd Zone in Surround back speaker setting
on page 37, three speaker system settings are possible
using the SPEAKERS button. If you selected Normal (SB)
or Front Bi-Amp, the button will simply switch your main
speaker system on or off. The options below are for the
1
2nd Zone setting only.
• Use the SPEAKERS button on the front panel to
select a speaker system setting.
As mentioned above, if you have selected Normal (SB),
the button will simply switch your main speaker system
(A) on or off.

Note
1 • The subwoofer output depends on the settings you made in Manual speaker setup on page 44. However, if SP B is selected above, no sound is heard
from the subwoofer (the LFE channel is not downmixed).
• Depending on the settings in Surround back speaker setting on page 37 output from the surround back pre-out terminals may change.
• All speaker systems (except 2nd Zone connections) are switched off when headphones are connected.

• SP A – Sound is output from speaker system A and
the same signal is output from the pre-out terminals.
• SP B – Sound is output from the two speakers
connected to speaker system B. Multichannel
sources will not be heard. The same signal is output
from the surround back channel pre-out terminals.
• SP AB – Sound is output from speaker system A (up
to 5 channels, depending on the source), the two
speakers in speaker system B, and the subwoofer.
The sound from speaker system B will be the same as
the sound from speaker system A (multichannel
sources will be downmixed to 2 channels).
• SP (off) – No sound is output from the speakers. The
same sound is output from the pre-out terminals
(including from your subwoofer, if connected) as
when selecting speaker system A (above).

Bi-amping your front speakers

Bi-amping is when you connect the high frequency driver
and low frequency driver of your speakers to different
amplifiers (in this case, to both front and surround back
terminals) for better crossover performance. Your
speakers must be bi-ampable to do this (having separate
terminals for high and low) and the sound improvement
will depend on the kind of speakers you're using.
1 Connect your speakers as shown below.
This illustration below shows the connections for bi-
amping your front left speaker. Hook up your front right
speaker in the same way.

Since both front and surround back speaker terminals
output the same audio, it doesn't matter which set (front
or surround back) is powering which part (High or Low)
of the speaker.
• Make sure that the + / – connections are properly
inserted.
