Set Up the AVR, continued
consult the technical specifications for your system’s main left and right speakers and 
locate the frequency response, usually given as a range, e.g., 80hz – 20khz (±3db). 
note the lowest frequency that the speakers are capable of playing (80hz in the above 
example). note: this frequency is not the same as the crossover frequency that may 
also be listed in the specifications.
use the remote’s left and right arrow buttons to select the crossover frequency that 
most closely matches the low frequency specification that you noted above. the AVr 
will divide the source signal at this crossover point, will send all information above the 
crossover point to your system’s speakers, and all information below the crossover point 
to the subwoofer. this way, each loudspeaker in your system will perform at its best, 
delivering a more powerful and enjoyable sound experience. record the setting in table 
A2 of the Appendix, on page 21.
7.  press the bAck button and select “Speaker distance.” the Speaker distance menu 
will appear.
8.  measure the distance from each speaker in your system to the listening position. 
record the distances in table A3 of the Appendix, on page 21.
9.  use the remote’s left and right arrow buttons to change the distance setting for each 
speaker so it matches the distance you wrote down in step 8. when you’re finished, 
press the remote control’s bAck button to return to the Speaker Setting menu.
10.  Select “channel level.” the channel level menu will appear. use the remote’s left 
and right arrow buttons to set test tone to “manual” and press the remote’s ok 
button. After the on-screen countdown you will hear test noise through the front left 
speaker.
11.  Sit in the main listening position and adjust the AVr’s volume control so the test noise 
is moderately loud. note the volume of the test noise through the first speaker. press 
the remote’s down arrow button to advance the test noise to each of your system’s 
speakers and note the volume level of the noise in each speaker.
12.  As you advance the test noise through the speakers, use the remote’s left and right 
arrow buttons to adjust the volumes of the channels until all of them play at the 
same volume.
Notes on Setting Speaker Volumes in Home Theater Systems:
while setting your system’s individual speaker volume levels is ultimately up to your 
personal taste, here are some ideas you may find helpful:
•  For  films  and  video-music  programs,  your  overall  goal  should  be  to  create  an 
enveloping, realistic sound field that draws you into the film or music program 
without drawing your attention away from the action on the screen.
•  For multichannel music recordings, some music producers will create a sound field 
that places the musicians all around you; others will create a sound field that places 
the musicians in front of you, with more subtle ambience in the surround speakers 
(as you would experience in a concert hall).
•  In most 5.1-channel film soundtracks, the surround speakers are not intended to be 
as loud or as active as the front speakers. Adjusting the surround speakers so they 
are always as loud as the front speakers could make dialogue difficult to understand 
and will make some sound effects sound unrealistically loud.
Notes on Setting Subwoofer Volume:
•  Sometimes the ideal subwoofer volume setting for music is too loud for films, while 
the ideal setting for films is too quiet for music. when setting the subwoofer volume, 
listen to both music and films with strong bass content and find a “middle ground” 
volume level that works for both.
•  If your subwoofer always seems too loud or too quiet, you may want to place it in 
a different location. placing the subwoofer in a corner will always tend to increase 
its bass output, while placing it away from any walls or corners will always tend to 
lessen its bass output.
13.  when you’re finished, record the settings in table A3 of the Appendix, on page 21, 
then press the remote’s Setup button to turn off the on-screen menus.
Additional Setup Menu Items
you can also adjust the following settings:
HDMI Set: Selecting Arc/cec on will send audio from the tV to the AVr via the hdmI 
Audio return channel (Arc) connection (which is in the hdmI cable connecting the AVr 
to the tV). this way, whenever you’re watching a source that is connected directly to 
your tV (such as an Internet connection), you can listen to the sound through the AVr by 
selecting tV as the AVr source device. Selecting on also allows the communication of 
control information among the hdmI devices in your system (cec).
Audio Settings: Selecting Audio Settings allows you to adjust the following audio 
settings:
•  Night  Mode  works  with  specially  encoded  Dolby
®
 digital discs or broadcasts, 
compressing the audio so that louder passages are reduced in volume to avoid 
disturbing others, while dialogue remains intelligible. press the left/right arrow 
buttons to advance through the following drc (dynamic range control) settings:
off: no compression is applied. loud passages in the program remain as they were 
recorded.
mid: loud passages in the program are reduced moderately in volume.
max: loud passages in the program are reduced more in volume.
Auto: Automatically compresses the audio a specific amount in response to 
instructions encoded in the dolby digital program.
•  PLII Music: Additional adjustments are avalable that allow you to fine-tune the Dolby 
pro logic II music surround mode’s performance for your listening room and personal 
taste:
panorama: with the panorama mode turned on, some of the sound from the front 
speakers is moved to the surround speakers, creating an enveloping “wraparound” 
effect. each press of the left or right arrow buttons toggles the setting on or off.
center width:
 this setting affects how vocals sound through the three front speakers. 
A lower number focuses the vocal information tightly on the center channel. higher 
numbers (up to 7) broaden the vocal soundstage. use the left/right arrow buttons to 
adjust this setting.
dimension:
 this setting affects the depth of the surround presentation, allowing you 
to “move” the sound toward the front or rear of the room. the setting of “0” is a 
neutral default. “+” settings  move the sound toward the front of the room, while “–” 
settings move the sound toward the rear. use the left/right arrow buttons to adjust it.
See Audio Processing and Surround Sound, on page 17, for more information about 
dolby pro logic II.
Auto Power Control: this setting allows you to set the AVr to automatically enter the 
Standby mode after a period of inactivity, saving energy. the available settings are off 
(default), 2 hours, 4 hours and 6 hours.
Speaker On/Off: use this setting to turn the speakers off when you are listening through 
headphones.

Operating Your AVR
Operating Your AVR
now that you have installed your components and completed a basic configuration, you 
are ready to begin enjoying your home theater system.
Controlling the Volume
Adjust the volume either by turning the front-panel Volume knob (clockwise to increase 
volume or counterclockwise to decrease volume) or by pressing the Volume up/down 
buttons on the remote. 
Muting the Sound
to mute all speakers and the headphones, press the mute button on the remote. Any 
recording in progress will not be affected. the mute message will appear in the front-
panel display as a reminder. to restore the sound, press the mute button again, or adjust 
the volume.
Listening Through Headphones
plug the 1/4-inch stereo plug on a pair of headphones into the front-panel phones jack for 
private listening. note: for information about turning off the speakers during headphone 
listening, see Additional Setup Menu Items – Speaker On/Off, on page 15.
Selecting a Source
there are two different ways to select a source:
•  Press the front-panel Source Select buttons. 
•  Directly select any source by pressing its Source Selector button on the remote. 
the AVr selects the analog audio and video inputs assigned to the source and any other 
settings you made during setup.
the digital audio inputs are not assigned to any specific sets of analog inputs. once you 
select a source device you can use the remote control’s Audio Input Select (dIgItAl) 
button to select the specific audio input connection (hdmI, coaxial digital, optical digital, 
analog) that you want to listen to. (note: you cannot select an audio input connection for 
the fm/Am or uSb source buttons.)
the source name, the selected audio input and the surround mode will appear on the 
front panel. 
Video Troubleshooting Tips
If there is no picture:
• Check the source selection.
• Check all connections for a loose or incorrect connection.
• Check the video-input selection on the TV/display device.
Additional Tips for Troubleshooting HDMI Connections
•  Turn off all devices (including the TV, the AVR and any source components).
•  Unplug the HDMI cables, starting with the cable between the AVR and the TV, and 
continuing with the cables between the AVr and each source device.
•  Carefully reconnect the cables from the source devices to the AVR. Connect the 
cable from the AVr to the tV last.
• Turn on the devices in this order: TV, AVR, source devices.
NOTE: Depending upon the particular components involved, the complexity of 
the required communication between HDMI components may cause delays of 
up to a minute in the completion of some actions, such as input switching or 
switching between SD and HD channels.
Listening to FM and AM Radio
Select the Am/fm source. use the tuning up/down buttons to tune a station, which will 
be shown on the front-panel display and the tV screen.
In the fm Stereo mode, the radio uses automatic tuning, meaning each press of the 
tuning up/down buttons scans until a station with acceptable signal strength is found. In 
the fm mono mode, the radio uses manual tuning, in which each press of a tuning button 
steps through a single frequency increment. (using the fm mono mode may improve the 
reception of weaker stations.) 
Preset Stations
A total of 30 stations (Am and fm combined) may be stored as presets. when the desired 
station has been tuned in, press the memory button and the preset number will flash on 
the front-panel message display. use the remote’s number buttons to enter the desired 
preset number.
to tune a preset station, press the preset up/down buttons or enter the preset number 
using the remote’s number buttons.
Listening to Media on a USB Device
your AVr is compatible with uSb 2.0 or uSb 1.1 media in the fAt 16 or fAt 32 file format 
and is compatible with the following mp3 and wmA media:
•  MP3:  Bit  rates  between  96  –  320kbps.  Fixed  bit-rates  at  44.1kHz  sampling  is 
recommended. Variable bit-rates (Vbr) are playable, but playing time may be 
displayed incorrectly. files must have a “.mp3” file extension.
•  WMA: Bit rates of 64kbps or higher. NOTE: Bit rates of 80kbps and 256kbps are not 
compatible. files must have a “.wma” file extension.
A maximum number of 65,536 folders and files can be supported.
Playing files on a USB device
1.  Insert the uSb drive into the AVr’s front-panel uSb port. ImportAnt: do not connect a 
personal computer or peripheral to the uSb port. uSb hubs are not supported.
2.  Select uSb as the source device. “uSb” will appear on the front-panel display, and 
after the AVr loads the contents of the current folder the uSb playback screen will 
appear on the oSd.

Operating Your AVR, continued,  
and Advanced Functions 
Selecting a Surround Mode
Selecting a surround mode can be as simple or sophisticated as your individual system 
and tastes. feel free to experiment, and you may find a few favorites for certain sources 
or program types. you can find more detailed information on surround modes in Audio 
Processing and Surround Sound, below.
to select a surround mode, press the Surround mode Select buttons. each press 
advances to the next available surround mode. 
digital surround-sound modes, such as dolby digital and dtS systems, are available only 
with specially encoded programs, such as those available via hdtV, dVd and blu-ray 
disc media and digital cable or satellite television. other surround modes such as dolby 
pro logic II may be used with digital or analog signals to create a different surround 
presentation or to use a different number of speakers.
Surround mode selection depends upon the number of speakers in your system, the 
programs you are watching or listening to, and your personal tastes.
Advanced Functions
much of the adjusting and configuration your AVr requires is handled automatically, with 
little intervention required on your part. you can also customize your AVr to suit your 
system and your tastes. In this section, we will describe some of the more advanced 
adjustments available to you.
Audio Processing and Surround Sound
Audio signals can be encoded in a variety of formats that affect not only the quality of the 
sound but also the number of speaker channels and the surround mode. you may also 
manually select a different surround mode, when available.
Analog Audio Signals
Analog audio signals usually consist of two channels – left and right. your AVr offers 
several options for analog playback:
•  Stereo: When you want conventional 2-channel playback, press the STEREO button. 
Sound will be output from the front left and right speakers. 
•  5-Ch Stereo: When you want to hear stereo sound through all of the system’s speakers 
(such as during a party), select 5ch Stereo via the Surround mode Select buttons. 
this plays the left-channel signal through the front left and surround left speakers, 
the right-channel signal through the front right and surround right speakers, and a 
summed mono signal through the center speaker. 
•  Analog  Surround  Modes:  Your  AVR  is  able  to  process  2-channel  audio  signals  to 
produce multi-channel surround sound, even when no surround sound has been 
encoded in the recording. Among the available modes are dolby pro logic II, dolby 
pro logic, dtS neo: 6, theater, hall, Stadium, club and Arena modes. use the 
Surround mode Select buttons to select one of these modes. See table A5 in the 
Appendix, on page 25, for breif explanations of each of these surround modes.
Digital Audio Signals
digital audio signals offer greater flexibility and capacity than analog signals and 
allow the encoding of up to 5.1 channels of discrete channel information directly into 
the signal. the result is improved sound quality and startling directionality, since each 
channel’s information is transmitted independently of the other channels. high-resolution 
recordings sound extraordinarily distortion-free, especially in the high frequencies.
digital surround-sound formats include dolby digital 2.0 (two channels only), dolby 
digital 5.1, dolby digital ex (6.1), dolby digital plus (7.1), dolby truehd (7.1), dtS-
hd high-resolution Audio (7.1), dtS-hd master Audio (7.1), dtS 5.1, dtS 96/24 (5.1), 
2-channel pcm modes in 44.1khz, 48khz, 88.1khz, 96khz or 176.4khz, and 5.1 or 
7.1 multichannel pcm. (your AVr will downmix the discrete surround back-channel 
information in 6.1-channel and 7.1-channel recordings into your system’s surround left 
and surround right channels.)
Surround Mode Selection
Surround-mode selection depends upon the format of the incoming audio signal as well 
as your personal taste. Although there is never a time when all of the AVr’s surround 
modes are available, the table below indicates which surround modes are available for 
a given input.
Input Signal Format
Available Surround Modes

club, Arena, 5-ch Stereo
when in doubt, check the broadcast or the jacket of your disc for more information 
on which surround modes are available. usually, nonessential sections of a disc, such 
as trailers, extra materials or the disc menu, are available only in dolby digital 2.0 
(2-channel) or pcm 2-channel mode. look for an audio setup section in the disc’s menu. 
Also, make sure your disc player’s audio output is set to the original bitstream rather than 
2-channel pcm. Stop play and check the player’s output setting.
Adjusting the Channel Volumes
In addition to using the AVr’s built-in test noise to configure the AVr for your speakers as 
explained in Configure the AVR for Your Speakers, you can also adjust the volume of any 
channel at any time to compensate for individual program sources or your personal taste.
1.  press the remote’s channel level button. the message display will show the left 
channel volume level.
2.  use the remote’s up and down arrow buttons to display the channel you want to adjust.
3.  use the remote’s left and right arrow buttons to adjust the channel’s volume.
press the bAck button when you’re finished.
Recording
two-channel analog audio signals, as well as composite video signals, are normally 
available at the appropriate recording output connectors. to make a recording, connect 
your audio or video recorder to the appropriate AVr output connectors as described in 
the Making Connections section, insert blank media in the recorder and make sure the 
recorder is turned on and recording while the source is playing. refer to the recording 
device’s instructions for complete information about making recordings.
noteS:
1.  the AVr does not convert digital signals to analog. only devices connected to the 
analog audio and composite video input connections can be recorded.
2. hdmI video sources are not available for recording.
3.  please make certain that you are aware of any copyright restrictions on any material 
you record. unauthorized duplication of copyrighted materials is prohibited by law.

the sleep timer sets the AVr to play for up to 90 minutes and then turn off automatically.
press the Sleep button on the remote, and the time until turn-off will be displayed on 
the front-panel message display the available settings are 30 min., 60 min., 90 min. 
and off.
when the sleep timer has been set, a small crescent-moon icon will appear on the front-
panel display.
If you press the Sleep button after the timer has been set, the remaining play time will be 
displayed. press the Sleep button again to change the play time.
Processor Reset
If the AVr behaves erratically after a power surge, first turn off the front-panel main 
power switch and unplug the Ac power cord for at least 3 minutes. plug the cord back 
in and turn the AVr on. If this procedure doesn’t help, reset the AVr’s processor as 
described below.
note: resetting the processor will erase all user configurations, including speaker and 
level settings, and tuner presets. After a reset, reenter all of these settings from your 
notes in the Appendix worksheets.
To reset the AVR’s processor:
1.  press the front-panel Standby/on switch to place the unit in the Standby mode (the
