Enjoying Home Theater

Thanks to the AV receiver's superb capabilities, you can enjoy surround sound with a real sense of movement in your own home—just like being in a movie theater or concert hall. With DVDs you can enjoy DTS and Dolby Digital. With analog and digital TV you can enjoy Dolby Pro Logic II or Onkyo's own DSP surround listening modes.

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 equidistant from the TV. Angle them inward so as to create a triangle,

with the listener at the apex.

Center speaker

This speaker enhances the front left and right speakers, making sound movements distinct and providing a full sound image. In 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.

Subwoofer

The subwoofer handles the bass sounds of the LFE (Low-Frequency Effects) channel. The volume and quality of the bass output from your subwoofer will depend on its position, the shape of your listening room, and your listening position. In general, a good bass sound can be obtained by installing the subwoofer in a front corner, or at one-third the width of the wall, as shown.

Tip: To find the best position for your subwoofer, while playing a movie or some music with good bass, experiment by placing your subwoofer at various positions within the room, and choose the one that provides the most satisfying results.

ONKYO HT-R640 - Subwoofer - 1

Surround left and right speakers

These speakers are used for precise sound positioning 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 equidistant from the listener.

About AV Connections

  • 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 jacks have shutter-type covers 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-channel audio inputs and outputs (typically labeled "R"). Use white plugs to connect left-channel audio inputs and outputs (typically labeled "L"). And use yellow plugs to connect composite video inputs and outputs.

ONKYO HT-R640 - AV Connection Color Coding - 1

  • Push plugs in all the way to make good connections (loose connections can cause noise or malfunctions).
  • To prevent interference, keep audio and video cables away from power cords and speaker cables.

ONKYO HT-R640 - Attaching the Speaker Labels (Not North American models) - 1

Speaker Connection Precautions

Read the following before connecting your speakers:

  • Only 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 levels 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 only to positive (+) terminals, and negative (-) terminals only to negative (-) 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.
  • Make sure the metal core of the wire does not have contact with the AV receiver's rear panel. Doing so may damage the AV receiver.
  • Don't connect more than one cable to each speaker terminal. Doing so may damage the AV receiver.
  • Don't connect one speaker to several terminals.

Connecting Components with HDMI

About HDMI

Designed to meet the demands of digital TV, HDMI (High Definition Multimedia Interface) is a new digital interface standard for connecting TVs, projectors, DVD players, set-top boxes, and other video components. Until now, several separate video and audio cables have been required to connect AV components. With HDMI, a single cable can carry control signals, digital video, and up to eight channels of digital audio (2-channel PCM, multichannel digital audio, and multichannel PCM).

The HDMI video stream (i.e., video signal) is compatible with DVI (Digital Visual Interface) ^1 , so TVs and displays with a DVI input can be connected by using an HDMI-to-DVI adapter cable. (This may not work with some TVs and displays, resulting in no picture.)

The AV receiver uses HDCP (High-bandwidth Digital Content Protection), so only HDCP-compatible components can display the picture.

The AV receiver's HDMI interface is based on the following standard:

High-Definition Multimedia Interface Specification Informational Version 1.1

Supported Audio Formats

2-channel linear PCM (32-192 kHz, 16/20/24 bit)
- Multichannel linear PCM (5.1 ch, 32–96 kHz, 16/20/24 bit)
- Bitstream (Dolby Digital, DTS)

Your DVD player must also support HDMI output of the above audio formats.

The AV receiver supports HDCP (High-bandwidth Digital Content Protection) ^2 , a copy-protection system for digital video signals. Other devices connected to the AV receiver via HDMI must also support HDCP.

Commercially available HDMI cables (supplied with some components) should be used to connect the AV receiver's HDMI OUT to the HDMI input on your TV or projector.

1 DVI (Digital Visual Interface): The digital display interface standard set by the DDWG ^3 in 1999.
2 HDCP (High-bandwidth Digital Content Protection): The video encryption technology developed by Intel for HDMI/DVI. It's designed to protect video content and requires a HDCP-compatible device to display the encrypted video.
*3 DDWG (Digital Display Working Group): Lead by Intel, Compaq, Fujitsu, Hewlett Packard, IBM, NEC, and Silicon Image, this open industry group's objective is to address the industry's requirements for a digital connectivity specification for high-performance PCs and digital displays.

Making HDMI Connections

Step 1: Use HDMI cables to connect the AV receiver's HDMI jacks to your HDMI-compatible DVD player, TV, projector, and so on.

Step 2: Assign each HDMI IN to an input selector in the HDMI Video setup (see page 40).

Video Signal Flow Chart

Digital video signals received at HDMI IN 1 and 2 are only output by the HDMI OUT and sent to your TV. Composite video, S-Video, and component video input signals are not output by the HDMI OUT.

ONKYO HT-R640 - Video Signal Flow Chart - 1

Note:

The onscreen setup menus are not output by the HDMI OUT, so you'll also need to make a composite video, S-Video, or component video connection to your TV (see page 24).

Audio Signal Flow Chart

Digital audio signals received at HDMI IN 1 or 2 are output by the speakers and headphones connected to the AV receiver. They're also output by the OPTICAL OUT and can be output by the HDMI OUT by setting the HDMI Audio Out setting to On (see page 69).

ONKYO HT-R640 - Audio Signal Flow Chart - 1

  • To listen to audio received at HDMI IN 1 and 2 through your TV speakers, set the HDMI Audio Out setting to On (see page 69) and your DVD player's output setting to PCM.

Connecting Onkyo RI Components

Step 1: Make sure that each Onkyo component is connected to the AV receiver with an analog audio cable (connection a in the hookup examples) (see pages 24 to 35).
Step 2: Make the RI connection.
Step 3: If you're using an MD, CDR, or HDD component, change the input display (see page 44).

With RI (Remote Interactive), you can use the following special functions:

Auto Power On/Standby

When you start playback on a component connected via RI, if the AV receiver is on Standby, it will automatically turn on and select that component as the input source. Similarly, when the AV receiver is set to Standby, all components connected via RI will also go on Standby. This function will not work on components connected to an AC OUTLET on the AV receiver.

Direct Change

When playback is started on a component connected via RI, the AV receiver automatically selects that component as the input source. If your DVD player is connected to the AV receiver's multichannel DVD input, you'll need to press the [MULTI CH] button to hear all channels (see page 46), as the Direct Change RI function only selects the FRONT DVD IN jacks.

Remote Control

You can use the AV receiver's remote controller to control your other RI-capable Onkyo components, pointing the remote controller at the AV receiver's remote control sensor instead of the component. You must enter the appropriate remote control code first (see page 73).

Notes:

  • Use only RL cables for RL connections. RL cables are supplied with Onkyo players (DVD, CD, etc.).
  • Some components have two RI jacks. You can connect either one to the AV receiver. The other jack is for connecting additional RI-capable components.
  • Connect only Onkyo components to RI jacks. Connecting other manufacturer's components may cause a malfunction.
  • Some components may not support all RI functions. Refer to the manuals supplied with your other Onkyo components.

ONKYO HT-R640 - Notes: - 1

Connecting the Power Cord of Another Component

The AV receiver has an AC outlet on its rear panel for connecting the power cord of another AV component. The other component's power switch can then be left in the ON position so that it turns on or off when the AV receiver is set to On or Standby.

ONKYO HT-R640 - Connecting the Power Cord of Another Component - 1

Caution:

Make sure that the capacity of the component that you connect to the AC OUTLET does not exceed the stated capacity (e.g., 100W).

Notes:

  • Onkyo components with R1 jacks should be connected directly to wall outlets, not the AV receiver's AC OUTLET.
  • The socket type and capacity will depend on the country in which you purchased the AV receiver.

ONKYO HT-R640 - Notes: - 1

ONKYO HT-R640 - Notes: - 2

Connecting the Power Cord

  • Connect the AV receiver's power cord to a suitable wall outlet.

Notes:

  • Before connecting the power cord, connect all of your speakers and AV components.
  • Turning on the AV receiver may cause a momentary power surge that might interfere with other electrical equipment on the same circuit. If this is a problem, plug the AV receiver into a different branch circuit.

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 available 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 information:

PS (Program Service)

When tuned to an RDS station that's broadcasting PS information, the station's name will be displayed. Pressing the [DISPLAY] button will display the frequency for 3 seconds.

RT (Radio Text)

When tuned to an RDS station that's broadcasting text information, the text will be shown on the display (see page 51).

PTY (Program Type)

This allows you to search for RDS radio stations by type (see page 51).

TP (Traffic Program)

This allows you to search for RDS radio stations that broadcast traffic information (see page 51).

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 displayed 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.

Neural Surround represents the latest advancement in surround technology developed for music and is adopted by XM Satellite Radio for digital radio broadcast of surround recordings and live events in surround sound. Neural Surround employs psychoacoustic frequency-domain processing, which allows delivery of a more detailed sound stage, with superior channel separation and localization of audio elements. System playback is scalable 5.1-channel surround playback.

Onkyo Original DSP Modes

Mono Movie

This mode is suitable for old movies and other mono 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, this mode emphasizes the surround channels in order to widen the stereo image, and simulates the natural reverberation of a large hall.

Unplugged

Suitable for acoustic instruments, vocals, and jazz, this mode emphasizes the front stereo image, giving the impression of being right in front of the stage.

Studio-Mix

Suitable for rock or 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

This mode adds realistic acoustics to TV shows produced in a TV studio, surround effects to the entire sound, and clarity to voices.

All Ch Stereo

Ideal for background music, this mode fills the entire listening area with stereo sound from the front and surround speakers.

Full Mono

In this mode, all speakers output the same sound in mono, so the sound you hear is the same regardless of where you are within the listening room.

T-D (Theater-Dimensional) or

With this mode you can enjoy a virtual 5.1 surround sound even with only two or three speakers. This works by controlling how sounds reach the listener's left and right ears. Good results may not be possible if there's too much reverb, so we recommend that you use this mode in an environment with little or no natural reverb.

This section explains how to record the current input source and how to dub audio onto your video recordings.

Notes:

  • The surround sound and DSP listening modes cannot be recorded.
  • Copy-protected DVDs cannot be recorded.
  • You cannot record from the DVD analog multichannel input.
  • Various restrictions apply to digital recording. Refer to the manuals supplied with your digital recording equipment for more details.
  • Digital signals received at COAXIAL IN/OPTICAL IN or HDMI IN 1/2 are only output by OPTICAL OUT. However, certain types of digital signal such as DVD-Audio signal input from HDMI IN will not be output. Analog input signals are output by only the analog outputs. There is no internal conversion from digital to analog or vice versa.
  • DTS signals will be recorded as noise, so don't attempt analog recording of DTS CDs or LDs.
  • While the listening mode is set to Pure Audio, no image is provided because the power is turned off for the video circuit. If you want to make recordings, select other listening mode.

AV Recording

Audio sources can be recorded to a recorder (e.g., cassette deck, CDR, MD) connected to the TAPE OUT or DIGITAL OPTICAL OUT jacks. Video sources can be recorded to a video recorder (e.g., VCR, DVD recorder) connected to the to VIDEO 1 OUT or VIDEO 2 OUT jacks. See pages 23 to 36 for hookup information.

1 DVD VIDEO 3 TUNER VIDEO 4 CDUse the input selector buttons to select the source that you want to record. You can watch the source while recording. The AV receiver's VOLUME control has no effect on recording.
2On your recorder, start recording.
3On the source component, start playback. If you select another input source during recording, that input source will be recorded.

Recording Separate AV Sources

Here you can record audio and video from completely separate 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.

In the following example, audio from the CD player connected to the CD IN, and video from the camcorder connected to the VIDEO 4 INPUT VIDEO jack are recorded by the VCR connected to the VIDEO 1 OUT jacks.

The Audio Adjust functions are explained below.

Input Channel Settings

Multiplex

This setting determines which channel is output from a stereo multiplex source. Use it to select audio channels or languages with multiplex sources, multilingual TV broadcasts, and so on.

Main: The main channel is output (default).

Sub: The sub channel is output.

Main/Sub: Both the main and sub channels are output.

Mono Input Ch

This setting specifies the channel to be used for playing any 2-channel digital source such as Dolby Digital, or 2-channel analog/PCM source in the Mono listening mode.

L + R : Both the left and right channels are output (default).

Left: Only the left channel is output.

Right: Only the right channel is output.

PL II Music Mode Settings

These settings provide for playing any 2-channel digital source such as Dolby Digital, or 2-channel analog/PCM source in the PLII Music listening mode.

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. It can be adjusted from -3 to +3 (default is 0). Lower settings move the sound field forward. Higher settings move it backward.

If the stereo image feels too wide, or there is too much surround sound, move the sound field forward to improve the balance. Conversely, if the stereo image feels like it is in mono, or there is not enough surround sound, move it backward.

Center Width

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 are using a center speaker, the center channel sound is output by only the center speaker. (If you are 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 setting controls the front left, right, and center mix, allowing you to adjust the weight of the center channel sound. It can be adjusted from 0 to 7 (default is 3).

Neo:6 Music Mode Setting

Center Image

The DTS Neo:6 Music listening mode creates 5.1-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 (-6dB) , 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 attenuated, maintaining the original stereo balance.

T-D Listening Setting

■ Listening Angle

With this setting, you can specify the angle of the front left and right speakers relative to the listening position. Processing for the Theater-Dimensional listening mode is based on this setting. Ideally, the front left and right speakers should be equidistant from the listening position and at an angle close to one of the two available settings.

ONKYO HT-R640 - ■ Listening Angle - 1

Narrow: Select if the listening angle is 20 degrees.

Wide: Select if the listening angle is 40 degrees (default).

Assigning Listening Modes to Input Sources

You can assign a default listening mode to each input source that will be selected automatically when you select each input source. For example, you can set the default listening mode to be used with Dolby Digital input signals. You can select other listening modes during playback, but the mode specified here will be resumed once the AV receiver has been set to Standby.

  • 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 62).

The DVD analog multichannel input doesn't work

  • Check the DVD analog multichannel input connections (page 26).
  • To select the DVD analog multichannel input, press the [MULTI CH] input selector button.
  • Check the audio output settings on your DVD player.

About DTS signals

  • When DTS program material ends and the DTS bitstream stops, the AV receiver remains in DTS listening mode and the DTS indicator remains on. This is to prevent 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 and LD players, you won't be able to playback DTS material properly even though your player is connected 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 recognize 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 malfunction.

The beginning of audio received by an HDMI IN can't be heard

  • Since it takes longer to identify the format of an HDMI signal than it does for other digital audio signals, audio output may not start immediately.

Video

There's no picture

  • Make sure that all video connecting plugs are pushed in all the way (page 18).
  • Make sure that each video component is properly connected.
  • If your video component is connected to a component video input, your TV must be connected to the component video output (page 23).
  • If a video component is connected to an HDMI input, your TV must be connected to the HDMI OUT.
  • While the Pure Audio listening mode (not North American models) is selected, the video circuitry is turned off and only video signals input through HDMI IN can be output.
  • On your TV, make sure that the video input to which the AV receiver is connected is selected.

There's no picture from a source connected to an HDMI IN

  • If the message "Resolution Error" appears on the AV receiver's display, this indicates that the TV or display does not support the current video resolution and you need to select another resolution on your DVD player.

The onscreen menus don't appear

  • The onscreen menus do not appear on a TV that's connected to the HDMI OUT.
  • Make sure that the video settings are correct (page 40).
  • On your TV, make sure that the video input to which the AV receiver is connected is selected.

The immediate display does not appear

  • The immediate display appears on a device connected to the COMPONENT Video OUT, when the Component Video Setup (page 41) is set to "---".
  • The immediate display does not appear on a device connected to the HDMI OUT.

Tuner

Reception is noisy, FM stereo reception is noisy, or the FM STEREO indicator doesn't appear

  • Relocate your antenna.
  • Move the AV receiver away from your TV or computer.
  • Listen to the station in mono (page 48).
  • 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.

Remote Controller

The remote controller doesn't work

  • Make sure that the batteries are installed with the correct polarity (page 12).
  • Install new batteries. Don't mix different types of batteries, or old and new batteries (page 12).
  • 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 12).
  • Make sure that the AV receiver is not subjected to direct sunshine or inverter-type fluorescent lights. Relocate if necessary.
  • If the AV receiver is installed in a rack or cabinet with colored-glass doors, the remote controller may not work reliably when the doors are closed.
  • Make sure you've selected the correct remote controller mode (pages 13-16).
  • When using the remote controller to control other manufacturers' AV components, some buttons may not work as expected.
  • Make sure you've entered the correct remote control code.
  • Make sure to set the same ID on both the AV receiver and remote controller (pages 69 and 71).

Can't control other components

  • If it's an Onkyo component, make sure that the RI cable and analog audio cable are connected properly. Connecting only an RI cable won't work (page 36).
  • Make sure you've selected the correct remote controller mode (pages 13-16).
  • If you've connected an R1-capable Onkyo MD recorder, CD recorder, or next generation HDD-compatible 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 display to MD, CDR, or HDD (pages 44 and 73).

  • To control another manufacturer's component, point the remote controller at that component.
  • To control an Onkyo component that's connected via RI, point the remote controller at the AV receiver. Be sure to enter the appropriate remote control code first (page 73).
  • To control an Onkyo component that's not connected via RI, or another manufacturer's component, point the remote controller at the component. Be sure to enter the appropriate remote control code first (page 72).

Recording

Can't record

  • On your recorder, make sure the correct input is selected (e.g., digital or analog).
  • When the Pure Audio listening mode (not North American models) is selected, recording is not possible because no video signals are output. Select another listening mode.

Others

The sound changes when I connect my headphones

  • When a pair of headphones is connected, the listening mode is set to Stereo, unless it's already set to Stereo, Mono, Direct, or Pure Audio (not North American models).

The speaker distance cannot be set as required

  • In some cases, corrected values suitable for home theater use may be set automatically.

The display doesn't work

  • The display is turned off when the Pure Audio (not North American models) listening mode is selected.

How do I change the language of a multiplex source

  • Use the "a. Multiplex" setting on the "Audio Adjust" menu to select Main or Sub (page 66).

The RI functions don't work

  • To use RI, you must make an RI connection and an analog audio connection (RCA) between the component and AV receiver, even if they are connected digitally (page 36).

The following settings can be made for the component video, S-Video, and composite video inputs

You must use the buttons on the unit to make these settings.

  1. While holding down the input selector button for the input source that you want to set, press the [SETUP] button.
  2. Use the Left and Right [] / [] buttons to change the setting.
  3. Press the [SETUP] button when you've finished.

Video Attenuation

This setting can be made for the DVD,VIDEO 1,VIDEO2,VIDEO3,orVIDEO4 input.

If you have a games console connected to a component video, S-Video or composite video input, and the picture isn't very clear, you can attenuate the gain.

Video ATT:0: (default).

Video ATT:2: Gain is reduced by 2 dB.

The AV receiver contains a microcomputer for signal processing 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 correctly.

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.

Before disconnecting the power cord from the wall outlet, set the AV receiver to Standby.
