ADVANCED FuNCTIONS
The setting for the surround back speakers includes a third option: Zone
2. The AVR 760/AVR 660 is capable of multizone operation, supporting
placement of a pair of speakers in another room. The AVR 760/AVR 660’s
assignable surround back amplifier channels make multizone operation
easier than ever, since an external power amplifier is not required. Select the
Zone 2 option at this line, and connect the Surround Back Speaker Outputs to
loudspeakers located in the remote room. The main room will be configured
automatically for up to 5.1 channels. See the Multizone Operation section for
more information.
NOTE : When the Surround Back speakers are set to “Zone 2”, they will not
be configured during the EzSet/EQ II process. To use the speakers in the
main listening area, configure them as “On”, and run the EzSet/EQ II process
for a 7.1- or 7.2-channel system. If the speakers will only be used during
multizone operation, configure them manually, as explained below.
The settings in this menu affect the remainder of the speaker setup process
and the availability of various surround modes at any time.
When you have finished, select the Back option or use the Back/Exit Button.
Adjust Crossover Frequencies Menu
After you have programmed the number of speakers, the AVR will return
to the Speaker Setup Position menu (see Figure 28). Navigate to the
Crossover (Size) line and press the OK Button to display the Adjust Crossover
Frequencies menu (see Figure 30).
Figure 30 – Adjust Crossover Frequencies Menu
The AVR will only display those speaker groups programmed in the Number of
Speakers menu.
Refer to Table A3 for each speaker’s crossover. For the main speakers, this is
the lowest frequency the speaker reproduces well.
For each main speaker, select one of the seven crossover frequencies: 40Hz,
60Hz, 80Hz, 100Hz, 120Hz, 150Hz or 200Hz. If the crossover frequency is
below 40Hz, select the first option, “Large”. This setting doesn’t refer to the
speaker’s physical size, but to its frequency response, which is also called “full
range”.
Specify the size of the subwoofer’s transducer as 8, 10, 12 or 15 inches (20,
25, 30 or 38 cm). The AVR always sets the subwoofer crossover to 100Hz, but
uses the transducer size for equalization. Write down the settings in Table A3
in the appendix.
When you have finished entering the settings, select Back, or press the Back/
Exit Button.
Sub Mode
Move the cursor to the Sub Mode line. This setting depends upon how you
programmed the front left and right speakers.
If you set the front speakers to a numeric crossover frequency, the •
subwoofer setting will always be LFE. All low-frequency information
will always be sent to the subwoofer. If you don’t have a subwoofer,
either upgrade to full-range speakers or add a subwoofer at the earliest
opportunity.
If you set the front speakers to LARGE, select one of the three settings for
•
the subwoofer.
L/R+LFE ♦ : This setting sends all low-frequency information to the
subwoofer, including both information that would normally be
played through the front left and right speakers, and the special low-
frequency effects (LFE) channel information.
Off
♦
: Select this setting when no subwoofer is in use. All low-
frequency information will be sent to the front left and right speakers.
LFE
♦
: This setting plays low-frequency information contained in the
left and right program channels through the front speakers, and
directs only the LFE channel to the subwoofer.
NOTE : If you are using a Harman Kardon HKTS Series speaker system,
select the appropriate numeric crossover frequency for the Main Speaker
groups, and the subwoofer will automatically be set to LFE.
Adjust Speaker Distance Menu
Placing the speakers at different distances from the listening positions can
muddy the sound, as sounds are heard earlier or later than desired.
Even if all of your speakers are placed the same distance from the listening
position, do not skip this menu.
On the Speaker Setup Position menu, move the cursor to the Distance line and
press the OK Button to display the Adjust Speaker Distance menu. See Figure
31.
Figure 31 – Adjust Speaker Distance Menu
Enter the distance from each speaker to the listening position, as measured
in Step Two – Measure Speaker Distances and recorded in Table A4 in the
appendix (see page 17).
The default unit of measurement is feet. To change the unit to meters, return
to the main AVR menu. Select the System Settings menu, then scroll down
to the General AVR Settings section and select the Unit of Measure line. Press
the OK Button to change the setting.
Select a speaker, then use the M N Buttons to change the measurement. The
values vary between 0 and 10 meter, with a default of 4 m for all speakers
except the Surround Left and Right Speakers, for which the default is 3,3
meter.
NOTE : If the surround back channels are assigned to the multizone
system, you will not be able to adjust their delay settings.
