ADVANCED FuNCTIONS
manuaL SpeaKer Setup
The AVR 760/AVR 660 is flexible and may be configured for most speakers, 
and to compensate for the acoustic characteristics of your room.
The EzSet/EQ II process automatically detects the capabilities of each speaker, 
and optimizes the AVR 760/AVR 660’s performance. If you are unable to run 
EzSet/EQ II calibration, or if you wish to make further adjustments, use the 
Manual Speaker Setup on-screen menus.
Before beginning, place your loudspeakers as explained in the Speaker 
Placement section, and connect them to the AVR. Consult the owner’s guide 
for the speakers or the manufacturer’s Web site for the frequency range 
specification. Although you may set the output levels “by ear,” an SPL (sound-
pressure level) meter purchased at a local electronics store will provide 
greater accuracy. 
Record your configuration settings in Tables A3 through A12 in the appendix 
for easy re-entry after a system reset, or if the AVR’s Master Power Switch is 
turned off or the unit is unplugged for more than four weeks.
NOTE: When using the AVR’s Speaker Setup menus, select a video output 
resolution of 720p or higher to view graphics that simplify configuration. 
Step one – Determine Speaker crossover
Without using the EzSet/EQ II process, the AVR 760/AVR 660 can’t detect how 
many speakers you’ve connected to it; nor can it determine their capabilities. 
Consult the speaker’s technical specifications and locate the frequency 
response, usually given as a range, e.g., 100Hz – 20kHz (±3dB). Write down 
the lowest frequency that each of your main speakers is capable of playing 
(100Hz in the example) as the crossover in Table A3 in the appendix. This is 
not the same as the crossover frequency listed in the speaker’s specifications. 
For the subwoofer, write down the transducer size.
The receiver’s bass management determines which speakers will be used to 
play back the low-frequency (bass) portion of the source program. Sending 
the lowest notes to small satellite speakers won’t sound right, and may even 
damage the speaker. The highest notes may not be heard at all through the 
subwoofer. 
With proper bass management, the AVR 760/AVR 660 divides the source 
signal at a crossover point. All information above the crossover point is played 
through the satellite speaker, and all information below the crossover point is 
played through the subwoofer. Each loudspeaker in your system performs at 
its best, delivering an enjoyable sound experience.
Step tWo – measure Speaker Distances
Ideally, all of your speakers would be placed in a circle, with the listening 
position at the center. However, you may have had to place some speakers a 
little further away from the listening position than others. Sounds that are 
supposed to arrive simultaneously from different speakers may blur, due to 
different arrival times.
Use the AVR’s Distance/Delay adjustment to compensate for real-world 
speaker placements.
Measure the distance from each speaker to the listening position, and write 
it down in Table A4 in the appendix. Even if all of your speakers are the 
same distance from the listening position, enter your speaker distances as 
described in Step Three. 
Step tHree – manual Setup menu
Now you are ready to program the receiver. Sit in the usual listening position 
and make the room as quiet as possible. 
With the receiver and video display turned on, press the AVR Settings Button 
to display the menu system. Use the 
L
 Button to move the cursor to the 
Speaker Setup line, and press the OK Button to display the Speaker Setup 
menu. See Figure 21 in the Basic Manual.
If you have run the EzSet/EQ II process, the results were saved in one of the 
two listening positions (AVR 760 position 1+2, AVR 660 1 position). Adjust 
the Speaker Setup setting in the Audio Effects menu to activate the results for 
either position (AVR 660: 1 position) (see page 26-27 in the Basic Manual). 
To tweak the EzSet/EQ II results, or to configure the AVR from scratch, select 
Setup Listening Position 1 (AVR 760, AVR 660) or Setup Listening Position 2 
(AVR 760). A screen similar to the one shown in Figure 28 will appear.
Figure 28 – Speaker Setup Position Menu 
NOTE: All of the speaker setup submenus include the Back option, as 
shown at the bottom of Figure 28. To save the current settings, select the 
Back option.
To reconfigure the speakers from scratch, select the Reset option.
For best results, adjust the submenus in this order: Number of Speakers, 
Crossover (Size), Sub Mode, Distance and Level Adjust.
Number of Speakers
Move the cursor to the Number of Speakers line and press the OK Button. See 
Figure 29.
Figure 29 – Number of Speakers Menu 
Program the correct setting for each speaker group: ON when the speakers are 
present in the system, and OFF for positions where no speakers are installed. 
The Front Left & Right speakers are always ON and may not be disabled. Any 
changes will be reflected in the total number of speakers displayed at the top 
of the screen.

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.

Step four – Setting channel output Levels 
manually
For a conventional 2-channel receiver, the balance control affects the stereo 
imaging by adjusting the relative loudness of the left and right channels.
With up to seven main channels, plus a subwoofer, imaging becomes both 
more critical and more complex. The goal is to ensure that each channel is 
heard at the listening position with equal loudness.
EzSet/EQ II calibration can handle this critical task for you, simply and 
automatically. However, the AVR’s Adjust Speaker Levels menu allows you 
to calibrate the levels manually, either using the system’s test tone or while 
playing source material. 
Make sure all speakers have been placed and connected correctly.
1. 
Adjust the number of speakers, crossover, distance and sub mode for each 
2. 
speaker in your system, as described in Step Three. 
Measure the channel levels in one of these ways, and adjust the channel 
3. 
levels using the Adjust Speaker Levels menu:
Preferably, use a handheld SPL meter set to the C-Weighting, Slow 
a) 
scale. Adjust each channel so that the meter reads 75dB.
By ear. Adjust the levels so that all channels sound equally loud.
b) 
If you are using a handheld SPL meter with source material, such as 
c) 
a test disc or an audio selection, play it and adjust the AVR’s master 
volume control until the meter measures 75dB.
Press the AVR Settings Button to display the menu system, and then navigate 
to the Speaker Setup line. Press the OK Button to display the Speaker Setup 
menu. Select Setup Listening Position 1 (AVR 760, AVR 660) or 2 (AVR 760), 
press the OK Button, and then navigate to the Level Adjust line. Press the OK 
Button to display the Adjust Speaker Levels menu. See Figure 32.
Figure 32 – Adjust Speaker Levels Menu 
All of the speaker channels will appear with their current level settings. 
Reset Levels: To reset all levels to their factory defaults of 0dB, scroll down 
to this line at the bottom of the menu and press the OK Button. 
To set your levels using the AVR 760/AVR 660’s internal test tone, adjust the 
TEST TONE line as follows:
Test Tone: Determines whether the test tone is active. To begin, press the 
OK Button repeatedly to select the OFF, AUTO or MANUAL setting. Manually 
moving the cursor out of the channel listings area of the screen automatically 
stops the test tone.
When this setting reads AUTO, the test tone will automatically circulate to 
all channels, pausing for a few moments at each channel and then moving 
to the next channel several seconds later, as indicated by the highlight bar. 
Adjust the level for any channel when the test tone is paused there, using the 
M N
 Buttons. Use the 
KL
 Buttons to move the cursor to another line, and 
the test tone will follow the cursor. 
When this setting reads MANUAL, the test tone will not move to the next 
channel until you use the 
KL
 Buttons.
Individual Channels: If you are using an external source to set your 
output levels, navigate to each channel and use the 
M N
 Buttons to adjust 
the level, as desired, between –10dB and +10dB.  
When you have finished adjusting the speaker levels, select the Back option 
or press the Back/Exit Button. Record the level settings in Table A3 in the 
appendix.
auDIo effectS
To adjust other audio settings, such as the tone controls, to improve 
performance, press the Audio Effects Button to display the Audio Effects 
menu (see Figure 24 in the Basic Manual). The menu may also be accessed 
from the Setup Source menu by pressing the Info Settings Button and 
selecting Audio Effects.
NOTE:  The settings in the Audio Effects menu affect each source 
independently.
Dolby Volume: See page 30 of the Basic Manual for an explanation of 
Dolby Volume processing and its benefits. Refer to Table 3 on that page for an 
explanation of each of the Dolby Volume settings.
Tone Control: Determines whether the treble and bass controls are active. 
When it’s off, the tone controls are “flat”, with no changes. When it’s on, the 
bass and treble frequencies are boosted or cut, depending upon the tone-
control settings. When an analog audio source is in use and the 2-Channel 
Stereo surround mode is selected, setting the Tone Control to “Off” places the 
unit in analog bypass mode.
Treble and Bass: Boost or cut the high or low frequencies by up to 10dB 
by using the 
M N
 Buttons to change the temperature bar setting. The default 
setting is 0dB, at the center of the temperature bar.
LFE Trim: Attenuates the loudness of the subwoofer. The setting defaults 
to the maximum of 0dB. Press the 
M N
 Buttons to reduce the level by up to 
10dB; the setting will appear as a negative number.
EQ: This setting activates or deactivates the equalization settings obtained 
when the EzSet/EQ II process was run. The settings are saved for reactivation 
at a later listening session. 
Speaker Setup: Select Position 1 (AVR 760, AVR 660) or 2 (AVR 760) to 
activate the speaker configuration settings saved for the desired position. 
The settings may be configured either by running the EzSet/EQ II process and 
saving the results, or manually, as explained in the Manual Speaker Setup 
section on page 6.
When you have finished, press the Audio Effects Button or the Back/Exit 
Button.

VIDeo aDjuStmentS
The AVR 760/AVR 660 uses leading-edge Faroudja DCDi Cinema video 
processing technology. Incoming video is upscaled to 1080p (1080i with 
component video outputs) for outstanding video quality, even with analog 
video sources. The Faroudja DCDi Cinema Dual 3D comb filters and 10-bit 
video processing eliminate the jagged edges and moiré patterns seen with 
less advanced processing.
The “Torino” video processing chip generates on-screen graphics in high 
definition, and blends it with the incoming video, so that you can continue to 
watch a program while using system menus. 
The video processor automatically provides the best picture based on the 
capabilities of your video display and the incoming source video. You may 
experiment with the Video Modes menu adjustments to try to improve the 
picture further. 
Video modes
Adjust the picture settings on your video display before adjusting the AVR. 
Access the picture settings from the Video Modes menu. Press the Video 
Modes Button, and the screen shown in Figure 33 will appear. The menu may 
also be accessed from the Info Settings menu.
NOTE:  The settings in the Video Modes menu affect each source 
independently.
Figure 33 – Video Modes Menu
Video Mode: The default setting of Off passes the video signal through to 
the display without any picture processing. Video scaling cannot be turned 
off, but selecting the HDMI Bypass mode in the Info Settings menu for a 
source connected to one of the HDMI Inputs passes the video signal directly 
from the HDMI Input to the HDMI Output, bypassing all video processing. 
Select one of these processing options to optimize the picture for the current 
program by applying adjustments to the brightness, contrast, color and 
sharpness: 
Sports
 
: For sporting events. 
Nature
 
: For programs shot outdoors, in a natural setting.
Movie
 
: For movies and many television broadcasts. 
Custom
 
: Allows manual adjustment of the picture settings. The 
Brightness, Contrast, Color and Sharpness settings appear as sliders with 
values ranging from 0 to 100. The default setting for each adjustment is 
50. Use the 
M N
 Buttons to change each setting’s value. 
Picture Adjust: Changes the aspect ratio of the displayed image. 
Widescreen (16:9) images are displayed on a full-screen (4:3) device in 
letterbox format. Black bars may appear above and below the image. 
When displaying full-screen images on a widescreen device, black or gray 
bars may appear to the left and right of the image (pillarboxing). 
Plasma and CRT monitors may suffer from “burn-in” when the same image, 
such as the horizontal or vertical bars, is left on screen for a long period of 
time. Adjust the picture so that it fills the display’s screen. Highlight this 
setting and press the OK Button. Each press of the 
KL
 Buttons changes the 
setting. Press the OK Button when the desired setting appears.
Auto Fit
 
: The AVR automatically adjusts the image, as required, to fit the 
display’s capabilities.
Height Fit
 
: Adjusts the image to eliminate any bars above or below it. 
Bars may remain at the sides.
Width Fit
 
: Adjusts the image to eliminate any bars on the sides. Bars 
may remain above and below the image.
Zoom 1x
 
: Displays the image as received from the source. If the image 
is in the 4:3 aspect ratio, on widescreen displays pillarbox format may be 
used. If the image is in the 16:9 aspect ratio, on full-screen (4:3) displays 
letterbox format may be used.
Zoom 2x
 
 and Zoom 3x: Stretches the image evenly to completely fill 
the screen. The outer portions of the image may be cropped.
Experiment with this setting until you find a pleasing display format for each 
program.
Overscan: For historical reasons, there is a convention to reserve an area 
around the border of a video frame, called “overscan”, that may be viewed on 
newer high-definition displays, although it was not visible on older analog 
television sets. However, since not all displays are capable of showing this 
portion of the frame, directors avoid placing important information in that 
area.
If your video display is capable of displaying the overscan area, turn this 
setting on to avoid seeing a black border around the image which could cause 
unwanted “burn-in” on some plasma and CRT displays. The AVR turns this 
setting off by default when the source device is connected to one of the HDMI 
Inputs. The setting is turned on by default when the source is connected to 
one of the analog video inputs.
Advanced Video Settings: Press the 
N
 or OK Button to display the 
Advanced Video Modes submenu (see Figure 34). This submenu is not 
accessible when the video processor (Video Mode setting) is turned off.
