Precautions

1. Recording Copyright

—Unless it’s for personal use

only, recording copyrighted material is illegal with-

out the permission of the copyright holder.

2. AC Fuse

—The AC fuse inside the unit is not user-

serviceable. If you cannot turn on the unit, contact

your Onkyo dealer.

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.

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.

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.

5. Never Touch this Unit with Wet Hands—

Never

handle this unit or its power cord while your hands

are wet or damp. If water or any other liquid gets

inside this unit, have it checked by your Onkyo

dealer.

6. Handling Notes

• If you need to transport this unit, use the original

packaging to pack it how it was when you origi-

nally bought it.

• Do not leave rubber or plastic items on this unit

for a long time, because they may leave marks on

the case.

• This unit’s top and rear panels may get warm

after prolonged use. This is normal.

• If you do not use this unit for a long time, it may

not work properly the next time you turn it on, so

be sure to use it occasionally.

Precautions

—Continued

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:

Blue: Neutral

Brown: Live

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:

The wire which is coloured blue must be connected to

the terminal which is marked with the letter N or

coloured black.

The wire which is coloured brown must be connected to

the terminal which is marked with the letter L or

coloured red.

IMPORTANT

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.

For European Models

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.

Supplied Accessories

Make sure you have the following accessories:

* In catalogs and on packaging, the letter at the end of the

product name indicates the color. Specifications and oper-

ation are the same regardless of color.

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.

•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.

Enjoying Home Theater

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.

Speaker Sets A and B

Speaker Set A: Main Room

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.

Surround left and right speakers

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.

*While speaker set B is on, these speakers output no

sound.

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

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.

Connecting Your Speakers

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.

No matter how many speakers you use, a powered sub-

woofer is recommended for a really powerful and solid

bass.

Before using the AV receiver, you must specify which

speakers are connected and their sizes (see page 34).

To get the very best from your surround-sound system,

you should also specify the distance between the listener

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.)

The AV receiver’s positive (+) speaker terminals are

color-coded for ease of identification. (The negative (–)

speaker terminals are all black.)

The supplied speaker labels are also color-coded and you

should attach them to the positive (+) side of each

speaker cable in accordance with the above table. All you

need to do then is to match the color of each label to the

corresponding speaker terminal.

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.

• Read the instructions supplied with your speakers.

•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.

• Unnecessarily long, or very thin speaker cables may

affect the sound quality and should be avoided.

• 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.

Connecting Your Speakers

—Continued

Using a suitable cable, connect the AV receiver’s SUB-

WOOFER PRE OUT to an input on your powered sub-

woofer, as shown. If your subwoofer is unpowered and

you’re using an external amplifier, connect the SUB-

WOOFER PRE OUT to an input on the amplifier.

Note:

Make sure the cable is plugged all the way.

The following illustration shows which speaker should be connected to each pair of terminals.

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.

The supplied indoor FM antenna is for indoor use only.

If you cannot achieve good reception with the supplied

indoor FM antenna, try a commercially available out-

door FM antenna instead (see page 21).

The supplied indoor AM loop antenna is for indoor use

only.

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).

Connecting the Indoor FM Antenna

1

Attach the FM antenna, as shown.

■

American Model

■

Other Models

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.

2

Fully extend the antenna and point it in

various directions to find the best recep-

tion. Secure it in that position with thumb-

tacks or something similar.

AM antenna push terminals

FM antenna jack

Insert the plug fully into the jack.

Insert the plug fully

into the jack.

Connecting the AM Loop Antenna

1

Assemble the AM loop antenna, inserting

the tabs into the base, as shown.

2

Connect both wires of the AM loop

antenna to the AM push terminals, as

shown.

(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.

Once your AV receiver is ready for use, you’ll

need to tune into an AM radio station and adjust

the position of the AM antenna to achieve the best

possible reception.

Keep the antenna as far away as possible from

your AV receiver, TV, speaker cables, and power

cords.

Connecting Antenna

—Continued

If you cannot achieve good reception with the supplied

indoor FM antenna, try a commercially available out-

door FM antenna instead.

Notes:

• Outdoor FM antennas work best outside, but usable

results can sometimes be obtained when installed in an

attic or loft.

•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.

If good reception cannot be achieved using the supplied

AM loop antenna, an outdoor AM antenna can be used in

addition to the loop antenna, as shown.

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.

Connecting Your Components

•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

The AV receiver’s optical digital jack has shutter-type

cover that open when an optical plug is inserted and

close when it’s removed. Push plugs in all the way.

Caution:

To prevent shutter damage, hold the optical

plug straight when inserting and removing.

AV Connection Color Coding

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.

•Push plugs in all the way to make

good connections (loose connec-

tions can cause noise or malfunc-

tions).

•To prevent interference, keep

audio and video cables away from

power cords and speaker cables.

Connecting Your Components

—Continued

By connecting both the audio and video outputs of your DVD player and other AV components to the AV receiver, you

can select both the audio and video simultaneously simply by selecting the appropriate input source on the AV receiver.

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

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.

Video Input/Output Diagram

Audio Connection Formats

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.

If your DVD player has a coaxial digital audio output jack, connect it to the AV receiver’s DIGITAL IN COAX-

IAL jack. You can enjoy Dolby and DTS listening modes with this connection.

If your DVD player has an optical digital audio output jack instead of coaxial one, connect it to the AV receiver’s

DIGITAL IN OPTICAL 1 or 2 jack, and set the DIGITAL INPUT assignment to OPT1 or OPT 2 (see page 33).

Coaxial connections perform the same as optical ones.

Optionally, connecting your DVD player’s audio out L/R jacks to the AV receiver’s DVD IN FRONT L/R jacks

will allow you to record audio from your DVD player.

Note: If your DVD player has main L/R output jacks and multichannel L/R output jacks, use the main L/R output

jacks.

—Multichannel Audio Connection—

If your DVD player has analog multichannel output jacks, connect them to the AV receiver’s DVD IN FRONT,

SURROUND, CENTER, and SUBWOOFER jacks. Use a multichannel analog cable or several normal audio

cables. You can enjoy DVD-Audio or SACD with this connection.

Make sure you also set your digital sources to send out a

digital signals. Please refer to the digital sources’ man-

ual.

If you connect an -capable Onkyo MiniDisc

recorder, CD recorder, or next generation HDD-compat-

ible component to the TAPE IN/OUT or VIDEO 3 IN

jacks, for to work properly, you must change this

setting.

This setting can only be changed on the AV receiver.

such as a DVD player or MPEG decoder. See page 25 for

hookup information.

Note:

•While the multichannel input is selected, the Speaker

Configuration settings on page 34 are ignored, and

signals from the multichannel input are fed to the front

left, front right, center, surround left, and surround

right speakers and subwoofer regardless of those set-

tings.

You can display various information about the current

input source as follows.

The following information can typically be displayed for

input sources.

*1 When AM or FM radio is used, the band, preset num-

ber, and frequency are displayed.

*2 If the input signal is analog, or AM or FM radio is

selected, no format information is displayed. If the

input signal is PCM, the sampling frequency is dis-

played. If the input signal is digital but not PCM, the

signal format is displayed. Information is displayed

for about 3 seconds, then the previous display reap-

pears.

Interpreting Surround Channel Information

A: The number of front channels (front left, front right,

and center).

B: The number of surround channels (surround left and

surround right). If there’s surround back channel

information, this number will be 3.

C: LFE channel for subwoofer (1 means yes).

Using the Multichannel Input

Press the [RECEIVER] button fol-

lowed by the [MULTI CH] button

Using RDS (European models only)

RDS only works with European models and only in areas

where RDS broadcasts are available. When tuned into an

RDS station, the RDS indicator appears.

■

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.).

The AV receiver supports four types of RDS informa-

tion:

PS (Program Service)

When tuned to an RDS station that’s broadcasting PS

information, the station’s name appears. When you press

the [DISPLAY] button, the frequency is displayed for

three seconds.

RT (Radio Text)

When tuned to an RDS station that’s broadcasting RT

text information, that information is shown on the dis-

play (see page 41).

PTY (Program Type)

You can also search for radio stations by type (see

page 41).

TP (Traffic Program)

You can also search for TP radio stations (see page 41).

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.

• If the signal from an RDS station is weak, RDS data

may be displayed intermittently or not at all.

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.

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.

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.

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.

Dolby Pro Logic II Music

Use this mode to add 5.1 surround to stereo sources such

as music CDs and DVDs.

Dolby Pro Logic II Game

Use this mode when playing game discs.

Dolby Digital

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.

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

player in order to enjoy DTS material. Use this mode

with DVDs and CDs that bear the DTS logo.

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.

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.

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.

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.

Unplugged

Suitable for acoustic instrument sounds, vocals, and jazz

music. By emphasizing the front stereo image, it simu-

lates the stage-front experience.

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.

TV Logic

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.

All Ch Stereo

Ideal for background music. The front, surround, and

surround back channels create a stereo image that fills

the entire listening area.

Full Mono

In this mode, all speakers output mono audio, so the

music sounds the same regardless of where you are.

This illustration shows which speakers are active in

each listening mode.

Adjusting the Listening Modes

—Continued

PL II Music Mode Settings

These settings apply to only 2-channel (stereo) sources.

■

Panorama

With this function, you can broaden the width of the

front stereo image when using the Pro Logic II Music

listening mode.

On:

Panorama function on.

Off:

Panorama function off (default).

■

Dimension

With this setting, you can move the sound field forward

or backward when using the Pro Logic II Music listening

mode. The default setting is 3. It can be adjusted from 0

to 6. Higher settings move the sound field forward.

Lower settings move it backward.

If the stereo image feels too wide, or there’s too much

surround sound, move the sound field forward to

improve the balance. Conversely, if the stereo image

feels like it’s in mono, or there’s not enough surround

sound, move it backward.

■

Center Width

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).

DTS Neo:6 Music Mode Setting

■

Center Image

This setting has an effect when you use a center speaker.

The DTS Neo:6 Music listening mode creates 5-channel

surround sound from 2-channel (stereo) sources. With

this setting, you can specify by how much the front left

and right channel output is attenuated in order to create

the center channel. It can be adjusted from 0 to 5 (default

is 2). This setting is unavailable if no surround speakers

are connected.

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.

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.

• The Late Night function is set to Off when the AV

receiver is set to Standby.

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.

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.

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 your AV

components to the AV receiver.

Notes:

•You cannot record from AV components that are con-

nected to the digital inputs. You must use analog con-

nections.

• The surround effects produced by the surround and

DSP listening modes cannot be recorded.

•You cannot record from an AV component that is con-

nected to the multichannel input.

•If you select another input source while recording, that

input source will be recorded instead.

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 the VIDEO 3

input and listen to the audio from the CD input.

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.

1.

Prepare the camcorder and CD player

for playback.

2.

Prepare the VCR for recording.

3.

Press the [VIDEO 3] input selector but-

ton.

4.

Press the [CD] input selector button.

This selects the CD player as the audio source, but

leaves the camcorder as the video source.

5.

Start recording on the VCR and start

playback on the camcorder and CD

player.

The video from the camcorder and the audio from

the CD player are recorded by the VCR.

Recording the Input Source

1

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 the VIDEO 1 OUT

and TAPE OUT jacks.

You can listen to the source while

recording. The AV receiver’s VOL-

UME control has no effect on record-

ing.

2

Start recording on the AV compo-

nent connected to the TAPE OUT

or VIDEO 1 OUT jacks.

tem, you need to set the crossover frequency according

to the size and frequency response of your speakers.

Notes:

•For a more accurate setting, look up the frequency

response in the manuals supplied with your speakers

and set accordingly.

•Choose a higher crossover frequency if you want more

sound from your subwoofer.

Double Bass

With the Double Bass function, you can boost bass out-

put by feeding bass sounds from the front left and right

channels to the subwoofer. This function can be set only

Speaker Distance

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.

Notes:

• 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).

• 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).

Speaker Levels

With this function, you can adjust the volume of each

speaker so that all speakers can be heard equally at the

listening position.

Note:

•A quicker way to adjust the speaker levels is to press

the remote controller’s [TEST TONE] button to output

the test tone, use the [LEVEL–] and [LEVEL+] but-

tons to adjust the levels, and use the [CH SEL] button

each channel of the multichannel input regardless of

the Speaker Configuration settings.

You can adjust the volume of each speaker from –

12 dB to +12 dB (–30 dB to +12 dB for the sub-

woofer).

The following table shows the display indicators for each

supported digital signal format.

Normally, the AV receiver detects the signal format auto-

matically. However, if you experience either of the fol-

lowing issues when playing PCM or DTS material, you

can manually set the signal format to PCM or DTS:

•If the beginnings of tracks from a PCM source are cut

off, try setting the format to PCM.

•If noise is produced when fast forwarding or reversing

a DTS CD, try setting the format to DTS.

Troubleshooting

If you have any trouble using the AV receiver, look for a

solution in this section.

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.

The AV receiver turns off as soon as it’s turned

on?

• 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.

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.

•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

correct, and that the bare wires are in contact with

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).

• If the MUTING indicator is shown on the display,

press the remote controller’s [MUTING] button to

unmute the AV receiver (page 43).

• 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.

•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-

nect an MC head amp, or an MC transformer and a

phono preamp.

•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

Auto (page 53).

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).

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.

• Make sure the speakers are configured correctly

(page 34).

The surround speakers produce no sound?

• When the Stereo or Mono listening mode is selected,

the surround speakers produce no sound (page 45).

• 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).

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-

back, so the subwoofer outputs no sound.

Power

Audio

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.

Note that resetting the AV receiver will delete your

radio presets and custom settings.

Troubleshooting

—Continued

• On the AV receiver, the subwoofer setting in the

speaker configuration is set to No. Set the subwoofer

setting to Yes.

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.

Can’t get 5.1-channel playback?

•When speaker B is turned on, speaker set A is reduced

to 2.1-channel playback.

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.

Noise can be heard?

• Using cable ties to bundle audio cables with power

cords, speaker cables, and so on may degrade the

audio performance, so don’t do it.

• An audio cable may be picking up interference. Try

repositioning your cables.

The Late Night function doesn’t work?

• Make sure the source material is Dolby Digital

(page 49).

The DVD analog multichannel input doesn’t

work?

• Check the DVD analog multichannel input connec-

tions (page 25).

•To select the DVD analog multichannel input, press

the [MULTI CH] input selector button (page 37).

• Check the audio output settings on your DVD player.

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.

•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.

There’s no picture?

•Make sure that all video connecting plugs are pushed

in all the way (page 22).

•Make sure that each video component is properly con-

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).

• On your TV, make sure that the video input to which

the AV receiver is connected is selected.

Reception is noisy, stereo FM reception suffers

from hiss, or the FM STEREO indicator doesn’t

appear?

• Relocate your antenna.

•Move the AV receiver away from your TV or com-

puter.

• Listen to the station in mono (page 38).

•When listening to an AM station, operating the remote

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).

The remote controller doesn’t work?

•Make sure that the batteries are installed with the cor-

rect polarity (page 9).

• Make sure that the remote controller is not too far

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).

•To control an Onkyo component that’s connected via

, point the remote controller at the AV receiver.

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).

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”

menu to select Main or Sub (page 48).

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).

Recording

Others

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.
