FCC Information for User  
CAUTION:  
2. AC Fuse—The AC fuse inside the unit is not user-  
serviceable. If you cannot turn on the unit, contact  
your Onkyo dealer.  
The user changes or modifications not expressly  
approved by the party responsible for compliance could  
void the user’s authority to operate the equipment.  
3. Care—Occasionally you should dust the unit all  
over with a soft cloth. For stubborn stains, use a soft  
cloth dampened with a weak solution of mild deter-  
gent and water. Dry the unit immediately afterwards  
with a clean cloth. Don’t use abrasive cloths, thin-  
ners, alcohol, or other chemical solvents, because  
they may damage the finish or remove the panel let-  
tering.

provide reasonable protection against harmful interfer-  
ence in a residential installation.  
This equipment generates, uses and can radiate radio  
frequency energy and, if not installed and used in accor-  
dance with the instructions, may cause harmful interfer-  
ence to radio communications. However, there is no  
guarantee that interference will not occur in a particular  
installation. If this equipment does cause harmful inter-  
ference to radio or television reception, which can be  
determined by turning the equipment off and on, the  
user is encouraged to try to correct the interference by  
one or more of the following measures:  
4. Power  
WARNING  
BEFORE PLUGGING IN THE UNIT FOR THE  
FIRST TIME, READ THE FOLLOWING SEC-  
TION CAREFULLY.  
AC outlet voltages vary from country to country.  
Make sure that the voltage in your area meets the  
voltage requirements printed on the unit’s rear panel  
(e.g., AC 230–240 V, 50 Hz or AC 120 V, 60 Hz).  
Some models have a voltage selector switch for  
compatibility with power systems around the world.  
Before you plug in such a model, make sure that the  
voltage selector is set to the correct voltage for your  
area.  
Reorient or relocate the receiving antenna.  
Increase the separation between the equipment and  
receiver.  
Connect the equipment into an outlet on a circuit dif-  
ferent from that to which the receiver is connected.  
Consult the dealer or an experienced radio/TV tech-  
nician for help.  
Pressing the [STANDBY/ON] button to select  
Standby mode does not fully shutdown the unit. If  
you do not intend to use the unit for an extended  
period, remove the power cord from the AC outlet.

Precautions—Continued  
Make sure you have the following accessories:  
For British models  
Replacement and mounting of an AC plug on the power  
supply cord of this unit should be performed only by  
qualified service personnel.  
IMPORTANT  
The wires in the mains lead are coloured in accordance  
with the following code:  
Remote controller & two batteries (AA/R6)  
Blue:  
Neutral  
Brown: Live  
(American type shown)  
As the colours of the wires in the mains lead of this  
apparatus may not correspond with the coloured mark-  
ings identifying the terminals in your plug, proceed as  
follows:  
Indoor FM antenna  
The wire which is coloured blue must be connected to  
the terminal which is marked with the letter N or  
coloured black.  
(Connector type varies from country to country.)  
The wire which is coloured brown must be connected to  
the terminal which is marked with the letter L or  
coloured red.  
IMPORTANT  
AM loop antenna  
The plug is fitted with an appropriate fuse. If the fuse  
needs to be replaced, the replacement fuse must  
approved by ASTA or BSI to BS1362 and have the same  
ampere rating as that indicated on the plug. Check for  
the ASTA mark or the BSI mark on the body of the fuse.  
If the power cord’s plug is not suitable for your socket  
outlets, cut it off and fit a suitable plug. Fit a suitable  
fuse in the plug.

Memory Backup  
The AV receiver uses a battery-less memory backup  
system in order to retain radio presets and other settings  
when it’s unplugged or in the case of a power failure.  
Although no batteries are required, the AV receiver  
must be plugged into an AC outlet in order to charge the  
backup system. Once it has been charged, the AV  
receiver will retain the settings for several weeks,  
although this depends on the environment and will be  
shorter in humid climates.

Notes:  
• The remote controller may not work reliably if the AV  
receiver is subjected to bright light, such as direct sun-  
light or inverter-type fluorescent lights. Keep this in  
mind when installing.  
• If another remote controller of the same type is used in  
the same room, or the AV receiver is installed close to  
equipment that uses infrared rays, the remote control-  
ler may not work reliably.  
• Don’t put anything, such as a book, on the remote con-  
troller, because the buttons may be pressed inadvert-  
ently, thereby draining the batteries.  
Slide the cover shut.

• The remote controller may not work reliably if the AV  
receiver is installed in a rack behind colored glass  
doors. Keep this in mind when installing.  
• The remote controller will not work if there’s an obsta-  
cle between it and the AV receiver’s remote control  
sensor.  
Notes:  
• If the remote controller doesn’t work reliably, try  
replacing the batteries.  
• Don’t mix new and old batteries or different types of  
batteries.  
• If you intend not to use the remote controller for a long  
time, remove the batteries to prevent damage from  
leakage or corrosion.  
• Expired batteries should be removed as soon as possi-  
ble to prevent damage from leakage or corrosion.

Enjoying Home Theater  
Speaker Sets A and B  
You can use two sets of speakers with the AV receiver: speaker set A and speaker set B.  
Speaker set A should be used in your main listening room for up to 5.1-channel playback.  
*While speaker set B is on, speaker set A is reduced to 2.1-channel playback.  
Speaker set B can be used in another room and offers 2-channel stereo playback.

Front left and right speakers  
These output the overall sound.Their role in a home theater is to provide a solid anchor for the sound  
image. They should be positioned facing the listener at about ear level, and equally spaced from the  
TV. Angle them inward.  
Center speaker  
This speaker enhances the  
front left and right speakers, making  
sound movements distinct and providing  
a full sound image. For movies it’s used  
mainly for dialog.  
Position it close to your TV facing forward  
at about ear level, or at the same height  
as the front left and right speakers.

While speaker set B is on, this speaker  
outputs no sound.  
Corner  
Subwoofer  
The subwoofer handles the bass  
sounds of the LFE (Low-Frequency  
Effects) channel. In general, a good  
bass sound can be obtained by  
installing the subwoofer in a front  
corner, or at one-third the way along  
the wall, as shown.

Speaker Set B: Sub Room  
These speakers are used for precise sound position-  
ing and to add realistic ambience. Position them at the  
sides of the listener, or slightly behind, about 2–3 feet  
(60–100 cm) above ear level. Ideally they should be  
equally spaced from the listener.

Speaker Connection Precautions  
For the best surround-sound experience, you should con-  
nect five speakers and a powered subwoofer.  
The following table shows which channels you should  
use based on the number of speakers that you have.  
Read the following before connecting your speakers:  
You can connect speakers with an impedance of  
6 ohms or higher. If you use speakers with a lower  
impedance, and use the amplifier at high volume lev-  
els for a long period of time, the built-in protection  
circuit may be activated.

• Disconnect the power cord from the wall outlet before  
making any connections.  
Front right  
• Read the instructions supplied with your speakers.  
Center  
• Pay close attention to speaker wiring polarity. In other  
words, connect positive (+) terminals to only positive  
(+) terminals, and negative (–) terminals to only nega-  
tive (–) terminals. If you get them the wrong way  
around, the sound will be out of phase and will sound  
unnatural.  
Surround left  
Surround right  
No matter how many speakers you use, a powered sub-  
woofer is recommended for a really powerful and solid  
bass.  
• Unnecessarily long, or very thin speaker cables may  
affect the sound quality and should be avoided.  
Before using the AV receiver, you must specify which  
To get the very best from your surround-sound system,  
and each individual speaker so that the sound from each  
speaker arrives at the listener’s ears at the same time (see  
page 52). In addition, you should set the level of each  
individual speaker to achieve an equal balance (see  
page 52.)  
• Be careful not to short the  
positive and negative wires.  
Doing so may damage the AV  
receiver.  
• Don’t connect more than one  
cable to each speaker termi-  
nal. Doing so may damage the  
AV receiver.  
• Don’t connect one speaker to several terminals.  
Attaching the Speaker Labels  
The AV receiver’s positive (+) speaker terminals are  
color-coded for ease of identification. (The negative (–)  
speaker terminals are all black.)

Connecting Antenna  
This section explains how to connect the supplied indoor  
FM antenna and AM loop antenna, and how to connect  
commercially available outdoor FM and AM antennas.  
The AV receiver won’t pick up any radio signals without  
any antenna connected, so you must connect the antenna  
to use the tuner.  
Connecting the AM Loop Antenna  
The supplied indoor AM loop antenna is for indoor use  
only.  
Assemble the AM loop antenna, inserting  
the tabs into the base, as shown.

Connecting the Indoor FM Antenna  
(The antenna’s wires are not polarity sensitive, so  
they can be connected either way around).  
Make sure that the wires are attached securely and  
that the push terminals are gripping the bare  
wires, not the insulation.  
The supplied indoor FM antenna is for indoor use only.  
Attach the FM antenna, as shown.

American Model  
Push  
Insert wire  
Release  
Insert the plug fully into the jack.  
Once your AV receiver is ready for use, you’ll  
need to tune into an AM radio station and adjust  
the position of theAM antenna to achieve the best  
possible reception.  
Other Models  
Keep the antenna as far away as possible from  
your AV receiver, TV, speaker cables, and power  
cords.  
Insert the plug fully  
into the jack.  
If you cannot achieve good reception with the supplied  
indoor AM loop antenna, try using it with a commer-  
cially available outdoor AM antenna (see page 21).  
Once your AV receiver is ready for use, you’ll  
need to tune into an FM radio station and adjust  
the position of the FM antenna to achieve the best  
possible reception.  
Fully extend the antenna and point it in  
2
various directions to find the best recep-  
tacks or something similar.  
If you cannot achieve good reception with the supplied  
indoor FM antenna, try a commercially available out-  
door FM antenna instead (see page 21).

Connecting an Outdoor FM Antenna  
Connecting an Outdoor AM Antenna  
If you cannot achieve good reception with the supplied  
indoor FM antenna, try a commercially available out-  
door FM antenna instead.  
If good reception cannot be achieved using the supplied  
AM loop antenna, an outdoorAM antenna can be used in  
addition to the loop antenna, as shown.  
Outdoor antenna  
Insulated antenna cable  
AM loop antenna  
Notes:  
• Outdoor FM antennas work best outside, but usable  
results can sometimes be obtained when installed in an  
attic or loft.  
Outdoor AM antennas work best when installed outside  
horizontally, but good results can sometimes be obtained  
indoors by mounting horizontally above a window. Note  
that the AM loop antenna should be left connected.  
Outdoor antenna must be grounded in accordance with  
local regulations to prevent electrical shock hazards.  
• For best results, install the outdoor FM antenna well  
away from tall buildings, preferably with a clear line  
of sight to your local FM transmitter.  
• Outdoor antenna should be located away from possi-  
ble noise sources, such as neon signs, busy roads, etc.  
• For safety reasons, outdoor antenna should be situated  
well away from power lines and other high-voltage  
equipment.  
• Outdoor antenna must be grounded in accordance  
with local regulations to prevent electrical shock haz-  
ards.  
Using a TV/FM Antenna Splitter  
It’s best not to use the same antenna for both FM and TV  
reception, as this can cause interference problems. If cir-  
cumstances demand it, use a TV/FM antenna splitter, as  
shown.

AV Connection Color Coding  
About AV Connections  
RCA-type AV connections are usually color coded: red,  
white, and yellow. Use red plugs to connect right-chan-  
nel audio inputs and outputs (typically labeled “R”). Use  
white plugs to connect left-channel audio inputs and out-  
puts (typically labeled “L”). And use yellow plugs to  
connect composite video inputs and outputs.  
• Before making any AV connections, read the manuals  
supplied with your other AV components.  
• Don’t connect the power cord until you’ve completed  
and double-checked all AV connections.  
Optical Digital Jacks

Which Connections Should I Use?  
The AV receiver supports several connection formats for compatibility with a wide range of AV equipment. The format  
you choose will depend on the formats supported by your other components. Use the following sections as a guide.  
For video components, such as a DVD player, you must make two connections—one for audio, one for video.  
Video Connection Formats  
Audio Connection Formats  
Video equipment can be connected to the AV receiver  
using one of the following video connection formats:  
composite video, or component video, the latter offering  
the best picture quality.  
When choosing a connection format, bear in mind that  
the AV receiver doesn’t convert between formats, so only  
outputs of the same format as the input will output the  
signal.  
For example, if you connect your DVD player to the  
COMPONENT VIDEO DVD IN, a video signal will be  
output by the COMPONENT OUT, but not by any com-  
posite video outputs.  
Audio equipment can be connected to the AV receiver  
using the following audio connection formats: analog,  
optical, coaxial, and multichannel.  
When choosing a connection format, bear in mind that  
the AV receiver doesn’t convert between formats.  
For example, audio signals connected to an OPTICAL or  
COAXIAL digital input are not output by the analog  
TAPE OUT, so if you want to record from, for example,  
your CD player, in addition to connecting it to a digital  
input, you must also connect it to the analog CD IN.

What is RDS?  
RDS stands for Radio Data System and is a method of  
transmitting data in FM radio signals. It was developed  
by the European Broadcasting Union (EBU) and is avail-  
able in most European countries. Many FM stations use  
it these days. In addition to displaying text information,  
RDS can also help you find radio stations by type (e.g.,  
news, sport, rock, etc.).  
Sport  
SPORT  
Live sports action, sports  
news, and interviews.  
Education EDUCATE Formal educational programs.  
Drama  
Culture  
DRAMA  
Radio plays and serials.  
CULTURE Cultural programs (including  
religious affairs).  
The AV receiver supports four types of RDS informa-  
tion:

play (see page 41).  
Rock music ROCK M Popular music with an alterna-  
tive appeal, often not appear-

Notes:  
• In some cases, the text characters displayed on the AV  
receiver may not be identical to those broadcast by the  
radio station. Also, unexpected characters may be dis-  
played when unsupported characters are received.  
This is not a malfunction.

About the Listening Modes  
With its built-in surround-sound decoders and DSP pro-  
grams, the AV receiver can transform your home listen-  
ing room into a movie theater or concert hall.  
Neo:6  
This mode provides 5.1-channel playback from 2-chan-  
nel sources. It offers five full-bandwidth channels with  
excellent separation. There are two modes of operation:  
Cinema mode for movies, and Music mode for listening  
to music.  
This illustration shows which speakers are active in  
each listening mode.  
Front left  
Center  
Front right  
Cinema mode simulates the realistic sense of movement  
that you get with 5.1-channel surround sound sources.  
Use this mode with videos, DVDs, and TV shows that  
feature stereo sound.  
Music mode uses the surround channels to simulate a  
natural sound field that cannot be produced with conven-  
tional stereo. Use this mode with stereo material such as  
music CDs.  
Subwoofer  
Surround  
left  
Surround  
right  
Direct  
The selected input source is output directly with minimal  
processing for a pure sound.  
Stereo  
The selected input source is processed as a stereo signal  
and output by the front left and right speakers and the  
subwoofer.  
Onkyo Original DSP Modes  
Mono Movie  
This mode is suitable for use with old movies and other  
mono sound sources. The center speaker outputs the  
sound as it is, while reverb is applied to the sound output  
by the other speakers, giving presence to even mono  
material.  
Mono  
Use this mode when watching an old movie with a mono  
soundtrack, or to select multilingual soundtracks  
recorded in the left and right channels of some movies.  
It can also be used when playing a DVD or other source  
with multiplexed audio, such as a karaoke DVD.  
Orchestra  
Suitable for classical or operatic music. The surround  
channels are emphasized in order to widen the stereo  
image. In addition, it simulates the natural reverberation  
of a large hall.  
Dolby Pro Logic II Movie  
Use this mode with DVDs and vid-  
eos that bear the Dolby Surround  
logo or TV shows that feature Dolby Surround. You can  
also use this mode with stereo movies or TV shows and  
the AV receiver will create a 5.1 surround mix from the  
2-channel stereo.  
Unplugged  
Suitable for acoustic instrument sounds, vocals, and jazz  
music. By emphasizing the front stereo image, it simu-  
lates the stage-front experience.  
Dolby Pro Logic II Music  
Use this mode to add 5.1 surround to stereo sources such  
as music CDs and DVDs.  
Studio-Mix  
Suitable for rock and pop music. Listening to music in  
this mode creates a lively sound field with a powerful  
acoustic image, like being at a club or rock concert.  
Dolby Pro Logic II Game  
Use this mode when playing game discs.  
TV Logic  
Dolby Digital  
Adds realistic acoustics to TV shows produced in a TV  
studio. In addition, it adds surround effects to the entire  
sound and adds clarity to voices.  
With this format you can experience the  
same superb sound that you get at a movie  
theater or concert hall. Use this mode with DVDs that  
bear the Dolby Digital logo.  
All Ch Stereo  
Ideal for background music. The front, surround, and  
surround back channels create a stereo image that fills  
the entire listening area.  
DTS  
This digital surround format offers a sur-  
round sound experience with exceptional  
fidelity. It uses compressed digital audio  
data, with six discrete channels (5.1), and the  
ability to handle large amounts of audio data while  
remaining faithful to the original. DTS provides very  
high-quality sound.You’ll need a DTS compatible DVD  
Full Mono  
In this mode, all speakers output mono audio, so the  
music sounds the same regardless of where you are.

These settings apply to only 2-channel (stereo) sources.  
With the Late Night function, you can reduce the  
dynamic range of Dolby Digital material so that you can  
still hear quiet parts even when listening at low volume  
levels—ideal for watching movies late at night when you  
don’t want to disturb anyone.

Notes:  
• The effect of the Late Night function depends on the  
Dolby Digital material that you are playing, and with  
some material there will be little or no effect.  
Center Width  
• The Late Night function is set to Off when the AV  
receiver is set to Standby.  
This setting has an effect when you use a center speaker.  
With this function, you can adjust the width of the sound  
from the center speaker when using the Pro Logic II  
Music listening mode normally. If you’re using a center  
speaker, the center channel sound is output by only the  
center speaker. (If you’re not using a center speaker, the  
center channel sound will be distributed to the front left  
and right speakers to create a phantom center). This set-  
ting controls the front left, right, and center mix, allow-  
ing you to adjust the weight of the center channel sound.  
It can be adjusted from 0 to 7 (default is 3).  
Using the CinemaFILTER  
With the CinemaFILTER, you can soften overly bright  
movie soundtracks, which are typically mixed for repro-  
duction in a movie theater.  
CinemaFILTER can be used with the following listening  
modes: Dolby Digital, Dolby Pro Logic II Movie, DTS,  
and DTS Neo:6 Cinema.

CINE FLTR  
When set to 0, the front left and right channel output is  
attenuated by half (–6 dB), giving the impression that the  
sound is located centrally. This setting works well when  
the listening position is considerably off center. When  
set to 5, the front left and right channels are not attenu-  
ated, maintaining the original stereo balance.

Recording  
This chapter explains how to record the selected input  
source to an AV component with recording capability,  
and how to record audio and video from two different  
sources.  
Recording from Different AV Sources  
With this function, you can record audio and video from  
different sources, allowing you to overdub audio onto  
your video recordings. This function takes advantage of  
the fact that when an audio-only input source (i.e.,  
TAPE, TUNER, or CD) is selected, the video input  
source remains unchanged. For example, if you first  
select the VIDEO 3 input source, followed by the CD  
input source, you can watch the video from theVIDEO 3  
input and listen to the audio from the CD input.  
Recording the Input Source  
You can record only to AV components that are con-  
nected to the TAPE OUT or VIDEO 1 OUT jacks.  
See pages 22–31 for information on connecting yourAV  
components to the AV receiver.  
In the following example, audio from the CD player con-  
nected to the CD IN jacks, and video from the camcorder  
connected to the VIDEO 3 IN jack are recorded by the  
VCR, which is connected to the VIDEO 1 OUT jacks.  
Use the input selector buttons to  
select the AV component that  
you want to record.  
Audio signals from the selected input  
source are output by theVIDEO 1 OUT  
and TAPE OUT jacks.

Speaker Distance  
• The Center and Subwoofer distances can be set up to  
5 ft. (1.5 m) more or less than the Front distance. For  
example, if the Front distance is set to 20 ft. (6 m), the  
Center and Subwoofer distances can be set between 15  
and 25 ft. (4.5 and 7.5 m).  
To get the best from surround sound, it’s important that  
the sound from each speaker reaches the listener at the  
same time. To achieve this, you need to specify the dis-  
tance from each speaker to the listening position.  
• The Surround distances can be set up to 5 ft. (1.5 m)  
more or 15 ft. (4.5 m) less than the Front distance. For  
example, if the Front distance is set to 20 ft. (6 m), the  
SurrRight and Surr Left distances can be set between  
5 and 25 ft. (1.5 and 7.5 m).

Troubleshooting  
If you have any trouble using the AV receiver, look for a  
solution in this section.  
If the MUTING indicator is shown on the display,  
press the remote controller’s [MUTING] button to  
unmute the AV receiver (page 43).  
If you can’t resolve the issue yourself, try resetting  
the AV receiver before contacting your Onkyo dealer.  
To reset the AV receiver to its factory defaults,  
turn it on and, while holding down the [VIDEO 1]  
button, press the [STANDBY/ON] button. “Clear”  
will appear on the display and the AV receiver will  
enter Standby mode.  
• While a pair of headphones is connected to the  
PHONES jack, no sound is output by the speakers  
(page 42).  
• Check the digital audio output setting on the con-  
nected device. On some games consoles, such as those  
that can play DVDs, the default setting is off.  
• With some DVD-Video discs, you need to select an  
audio format from a menu.  
VIDEO 1/VCR  
STANDBY/ON  
• If your turntable doesn’t have a phono preamp built-in,  
you must connect one between it and the AV receiver.  
If your turntable uses an MC cartridge, you must con-  
phono preamp.  
Note that resetting the AV receiver will delete your  
radio presets and custom settings.  
• Specify the speaker distances and adjust the individual  
speaker levels (pages 52, 53).  
• The input signal format is set to PCM or DTS. Set it to  
Power  
Can’t turn on the AV receiver?  
• Make sure that the power cord is properly plugged into  
the wall outlet.  
• Unplug the power cord from the wall outlet, wait five  
seconds or more, then plug it in again.  
Only the front speakers produce sound?  
• When the Stereo or Mono listening mode is selected,  
only the front speakers and subwoofer produce sound.  
• Make sure the speakers are configured correctly  
(page 34).  
The AV receiver turns off as soon as it’s turned  
on?  
Only the center speaker produces sound?  
If you use the Pro Logic II Movie or Pro Logic II  
Music listening mode with a mono source, such as an  
AM radio station or mono TV program, the sound is  
concentrated in the center speaker.  
• The amp protection circuit has been activated.  
Remove the power cord from the wall outlet immedi-  
ately. Disconnect all speaker cables and input sources,  
and leave the AV receiver with its power cord discon-  
nected for one hour. After that, reconnect the power  
cord, and then set the volume to maximum. If the AV  
receiver stays on, set the volume to minimum, discon-  
nect the power cord, and reconnect your speakers and  
input sources properly. If the AV receiver turns off  
when you set the volume to maximum, disconnect the  
power cord, and contact your Onkyo dealer.  
• Make sure the speakers are configured correctly  
(page 34).  
The surround speakers produce no sound?  
• When the Stereo or Mono listening mode is selected,  
• Depending on the source and current listening mode,  
not much sound may be produced by the surround  
speakers. Try selecting another listening mode.  
• Make sure the speakers are configured correctly  
(page 34).  
Audio  
There’s no sound or it’s very quiet?  
• Press the SPEAKERS [A] or [B] button to turn on the  
indicator for the speakers that you want to output  
sound.  
• Make sure that the digital input source is selected  
properly (page 33). Press the [DIGITAL INPUT] but-  
ton repeatedly.  
The center speaker produces no sound?  
• When the Stereo or Mono listening mode is selected,  
the center speaker produces no sound (page 45).  
• Make sure the speakers are configured correctly  
(page 34).  
The subwoofer produces no sound?  
• The subwoofer outputs no sound while only speaker  
set B is on. Turn on speaker set A.  
• When you play source material that contains no infor-  
mation in the LFE channel, the subwoofer produces  
no sound.  
• Make sure the speakers are configured correctly  
(page 34).  
• If the multichannel DVD input is selected and speaker  
set B is on, speaker set A is reduced to 2-channel play-

• Make sure that all audio connecting plugs are pushed  
in all the way (page 22).  
• Make sure that the polarity of the speaker cables is  
metal part of each speaker terminal (pages 18, 19)  
• Make sure that the speaker cables are not shorting.  
• Check the volume. The AV receiver is designed for  
home theater enjoyment and has a wide volume range  
for precise adjustment (page 36).

Troubleshooting—Continued  
• On the AV receiver, the subwoofer setting in the  
speaker configuration is set to No. Set the subwoofer  
setting to Yes.  
Video  
There’s no picture?  
• Make sure that all video connecting plugs are pushed  
in all the way (page 22).  
There’s no sound with a certain signal format?  
• Check the digital audio output setting on the con-  
nected device. On some games consoles, such as those  
that can play DVDs, the default setting is off.  
• With some DVD-Video discs, you need to select an  
audio output format from a menu.  
nected.  
• The AV receiver does not convert between formats, so  
if a video source component is connected to a compo-  
nent video input, your TV must be connected to the  
component video output (page 23).  
Can’t get 5.1-channel playback?  
• When speaker B is turned on, speaker setA is reduced  
to 2.1-channel playback.  
• On your TV, make sure that the video input to which  
the AV receiver is connected is selected.  
The volume cannot be set to 79?  
• When the subwoofer volume level is set to a positive  
(+) value, the maximum master volume level is  
reduced proportionally.  
Tuner  
Reception is noisy, stereo FM reception suffers  
appear?

controller may cause noise.  
• Passing cars and airplanes can cause interference.  
• Concrete walls weaken radio signals.  
• If nothing improves the reception, install an outdoor  
antenna (page 21).  
Noise can be heard?  
• Using cable ties to bundle audio cables with power  
cords, speaker cables, and so on may degrade the  
• An audio cable may be picking up interference. Try  
repositioning your cables.

rect polarity (page 9).  
About DTS signals  
• When DTS program material ends and the DTS bit-  
stream stops, the AV receiver remains in DTS listening  
mode and the DTS indicator remains on. This is to pre-  
vent noise when you use the pause, fast forward, or fast  
reverse function on your player. If you switch your  
player from DTS to PCM, because the AV receiver  
does not switch formats immediately, you may not hear  
any sound, in which case you should stop your player  
for about three seconds, and then resume playback.  
• With some CD players, you won’t be able to playback  
DTS material properly even though your player is con-  
nected to a digital input on the AV receiver. This is  
usually because the DTS bitstream has been processed  
(e.g., output level, sampling rate, or frequency  
response changed) and the AV receiver doesn’t recog-  
nize it as a genuine DTS signal. In such cases, you  
may hear noise.  
away from the AV receiver, and that there’s no  
obstruction between the remote controller and the AV  
receiver’s remote control sensor (page 9).  
• Make sure you’ve selected the correct remote control-  
ler mode (page 10).  
• Make sure you’ve entered the correct remote control  
code.  
Can’t control other components?  
• Make sure you’ve selected the correct remote control-  
ler mode (page 10).  
• If you’ve connected an  
-capable Onkyo MD  
recorder, CD recorder, or next generation HDD-com-  
patible component to the TAPE IN/OUT jacks, or a  
DS-A1 Remote Interactive Dock to the VIDEO 3 IN  
jacks, for the remote controller to work properly, you  
must set the Input Display to MD, CDR, or HDD (see  
page 33).  
• When playing DTS program material, using the pause,  
fast forward, or fast reverse function on your player  
may produce a short audible noise. This is not a mal-  
function.  
• To control an Onkyo component that’s connected via  
, point the remote controller at the AV receiver.

Troubleshooting—Continued  
Recording  
Can’t record?  
• On your recorder, make sure the correct input is  
selected.  
• To prevent signal loops and damage to the AV  
receiver, input signals are not fed through to outputs  
with the same name (e.g., TAPE IN to TAPE OUT, or  
VIDEO 1 IN to VIDEO 1 OUT).  
Others  
The sound changes when I connect my head-  
phones?  
• When a pair of headphones is connected, the listening  
mode is set to Stereo, unless it’s already set to Stereo,  
Mono, Direct.  
How do I change the language of a multiplex  
source?  
• Use the “Multiplex” setting on the “4. Audio Adjust”  
The  
functions don’t work?  
• To use  
, you must make an  
connection and an  
analog audio connection (RCA) between the compo-  
nent and AV receiver, even if they are connected digi-  
tally (page 31).  
The AV receiver contains a microcomputer for signal pro-  
cessing and control functions. In very rare situations,  
severe interference, noise from an external source, or  
static electricity may cause it to lockup. In the unlikely  
event that this happens, unplug the power cord from the  
wall outlet, wait at least five seconds, and then plug it  
back in again.  
Onkyo is not responsible for damages (such as CD  
rental fees) due to unsuccessful recordings caused by  
the unit’s malfunction. Before you record important  
data, make sure that the material will be recorded cor-  
rectly.  
Before disconnecting the power cord from the wall out-  
let, set the AV receiver to Standby.
