AVR235 harman/kardon

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called

Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and

semiconductor "chip" components.

The following techniques should be used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on

your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,

which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to

prevent electrostatic charge build-up or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges

sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement

ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the

chassis or circuit assembly into which the device will be installed.

CAUTION :

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together

or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

Each precaution in this manual should be followed during servicing.

Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with

, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the

parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably

insulated from the supply circuit before retuming the product to the customer.

SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed o.5mA.

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

AVR235 harman/kardon

INSTALLATION AND CONNECTIONS

System Installation

After unpacking the unit, locating it in a place with adequate ventilation and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment.

IMPORTANT NOTE: For your personal safety and to avoid possible damage to your equipment and speakers, it is always a good practice to turn off and unplug the AVR and ALL source equipment from the AC output before making any audio or video system connections.

Audio Equipment Connections

We recommend that you use high-quality interconnect cables when making connections to source equipment and recorders to preserve the integrity of the signals.

1. Connect the analog output of a CD player to the

CD Audio Inputs ¡.

NOTE: When the CD player has both fixed and vari-

able audio outputs, it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or so high that it is distorted.

2. Connect the analog Play/Out jacks of a cassette

deck, MD, CD-R or other audio recorder to the Tap e Input Jacks . Connect the analog Record/In jacks on the recorder to the Tape Output Jacks ™ on the AVR 235.

3. Connect the output of any digital sources such

as a CD or DVD changer or player, advanced video game, a digital satellite receiver, HDTV tuner or digital cable set-top box or the output of a compatible computer sound card to the Optical and Coaxial Digital Audio Inputs ad*(.

4. Connect the coaxial or optical Digital Audio Outputs

‡° on the rear panel of the AVR 235 to the matching digital input connections on a CD-R or MiniDisc recorder.

5. Assemble the AM Loop Antenna supplied with the

unit so that the tabs at the bottom of the antenna loop snap into the holes in the base. Connect it to the AM Antenna Terminals .

6. Connect the supplied FM antenna to the FM (75-

ohm) Connection . The FM antenna may be an external roof antenna, an inside powered or wire-lead antenna or a connection from a cable TV system. If the antenna or connection uses 300-ohm twin-lead cable, you must use an optional 300-ohm-to-75-ohm adapter to make the connection.

7. Connect the front, center, surround and surround back speaker outputs ¶•ª‚ to the respective speakers.

To ensure that all the audio signals are carried to your speakers without loss of clarity or resolution, we suggest that you use high-quality speaker cable. Many brands of cable are available and the choice of cable may be influenced by the distance between your speakers and the receiver, the type of speakers you use, personal preferences and other factors. Your dealer or installer is a valuable resource to consult in selecting the proper cable.

Regardless of the brand of cable selected, we recommend that you use a cable constructed of copper with a gauge of 14 or smaller.

multistrand

Remember that in specifying cable, the lower the number, the thicker the cable.

Cable with a gauge of 16 may be used for short runs of less than 10 feet. We do not recommend that you use cables with an AWG equivalent of 18 or higher, due to the power loss and degradation in performance that will occur.

Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other appropriate testing agency standards. Questions about running cables inside walls should be referred to your installer or a licensed electrician who is familiar with the NEC and/or the applicable local building codes in your area.

When connecting wires to the speakers, be certain to observe proper polarity. Note that the positive (+) terminal of each speaker connection now carries a specific color code, as noted on page 7. However, most speakers still use a red terminal for the positive (+) connection. Connect the “negative” or “black” wire to the same terminal on both the receiver and the speaker.

NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some may vary from this configuration. To ensure proper phase and optimal performance, consult the identification plate on your speaker or the speaker’s manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer for advice before proceeding, or consult the speaker’s manufacturer.

We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the front-left and front-right or surround-left and surround-right speakers, even if the speakers are a different distance from the AVR 235.

It is appropriate to configure the AVR 235 for either

5.1- or 7.1-channel operation, but not for 6.1 channels. When 6.1-channel program material or a

6.1-channel processing mode is in use, material for the surround back channel will be outputted simultaneously through both the Surround Back Left and Right Speaker Outputs •. Connecting only one loudspeaker to these speaker terminals will not only deprive you of the benefits of 7.1-channel surround modes, such as Logic 7, but will also interfere with the functioning of EzSet speaker calibration, as described on page 23. It may also put undesirable strain on the surround back amplifier circuits and power supplies.

8. Connections to a subwoofer are normally made via a line-level audio connection from the Subwoofer Output § to the line-level input of a subwoofer with a built-in amplifier. When a passive subwoofer is used, the connection first goes to a power amplifier, which will be connected to one or more subwoofer speakers. If you are using a powered subwoofer that does not have line-level input connections, follow the instructions furnished with the speaker for connection information.

9. If an external multichannel audio source with 5.1 outputs such as an external digital processor/decoder, DVD-Audio or SACD player is used, connect the outputs of that device to the 6/8-Channel Direct

Inputs g.

Video Equipment Connections

Video equipment is connected in the same manner as audio components. Again, the use of high-quality interconnect cables is recommended to preserve signal quality.

1. Connect a VCR’s, personal video recorder’s (PVR) or other video source’s audio and video Play/Out jacks to the Video 1 or Video 2 Audio/Video and S-Video Input Jacks cf on the rear panel. The

Audio and Video Record/In jacks on the VCR should be connected to the Video 1 or Video 2 Audio/ Video and S-Video Output Jacks eh

on the AVR 235.

Although any video device may be connected to these jacks, we recommending connecting your video recorder to the Video 1 Audio/Video and S-Video

Input and Output Jacks ce so that you

may take advantage of the fact that the remote control is preprogrammed with video recorder product codes for the Video 1 device.

2. Connect the analog audio and video outputs of a satellite receiver, cable TV converter, television set or any other video source to the Video 2 or

Video 3 Audio/Video and S-Video Input Jacks

fhi .

14 INSTALLATION AND CONNECTIONS

AVR235 harman/kardon

INSTALLATION AND CONNECTIONS

Although any video device may be connected to these jacks, we recommend connecting your cable TV converter or satellite receiver so that you may take advantage of the fact that the remote control is preprogrammed with the product codes of these device types for the Video 2 device. If your device is capable of switching component video, we particularly recommend connecting it to the Video 2 Audio Input

Jacks , as the Video 2 Component Video Inputs ¤ are assigned to the Video 2 device.

3. Connect the analog audio and video outputs of a television or other video device to the Video 3 Audio/Video and S-Video Input Jacks i . Although any video or audio device may be connected to these jacks, we recommend connecting your TV so that you may take advantage of the fact that the remote control is preprogrammed with television product codes for the Video 3 device. IMPORTANT: If you are only using the television as a display device (i.e., if you receive your television programs through a cable box or satellite receiver), do not connect the TV’s outputs to the Video 3 Audio/Video and S-Video Input Jacks i , or to any other inputs on the AVR 235.

4. Connect the analog audio and video outputs of a DVD or laser disc player to the DVD Audio/Video and S-Video Inputs bk.

5. Connect the digital audio outputs of a DVD player, satellite receiver, cable box or HDTV converter to the appropriate Optical or Coaxial Digital Inputs ad*(.

6. Connect the Video and/or S-Video Monitor Output ·j jacks on the receiver to the composite or S-Video input of your television monitor or video projector.

7. If your DVD player and monitor both have component video connections, connect the component outputs of the DVD player to the DVD Component Video Inputs ‹. Even when component video connections are used, the audio connections should still be made to either the analog DVD Audio Inputs k or any of the Optical or Coaxial Digital Input Jacks ad*(.

8. If another device with component video outputs is available, connect it to the Video 2 Component Video Inputs ¤. The audio connections for this device should be made to either the Video 2 Audio

Inputs or any of the Optical or Coaxial Digital Input Jacks ad*(

9. If the component video inputs are used, connect the Component Video Monitor Outputs ⁄ to the component video inputs of your TV, projector or display device.

10. If you have a camcorder, video game or other audio/video device that is connected to the AVR on a temporary rather than permanent basis, connect the audio, video and digital audio outputs of that device to the Front-Panel Inputs *(ÓÔ. A device connected here is selected as the Video 4 input, and the digital inputs must be assigned to the Video 4 input. (See page 17 for more information on input configuration.)

Video Connection Notes:

• When the component video jacks are used, the onscreen menus are not visible and you must switch to the standard composite or S-Video input on your TV to view them.

• The AVR 235 will accept either standard composite, S-Video or Y/Pr/Pb component video signals. However, it will not convert any of these signals to a different format.

• When connecting a video source to the AVR 235, you may use composite, component or S-Video, but only one type of video may be connected for each device.

• When more than one video format is used, it is necessary to make a separate connection from the AVR to your video display for each format. For example, if both composite and component sources are connected to the AVR 235, both the

Composite and Component Video Monitor Outputs ⁄j must be connected to the appro-

priate inputs on your video display.

AC Power Connections

This unit is equipped with two accessory AC outlets. They may be used to power accessory devices, but they should not be used with high-current-draw equipment such as power amplifiers. The total power draw to each outlet may not exceed 100 watts.

The Switched AC Accessory Outlet ﬁ will receive power only when the unit is on. This is recommended for devices that have no power switch or a mechanical power switch that may be left in the “ON” position.

NOTE: Many audio and video products go into a Standby mode when they are used with switched outlets, and cannot be fully turned on using the outlet alone without a remote control command.

The Unswitched AC Accessory Outlet ﬂ will receive power as long as the unit is plugged into a powered AC outlet.

Once the AC Power Cord › is connected, you are almost ready to enjoy the AVR 235’s incredible power and fidelity!

OPERATION

Basic Operation

Once you have completed the initial setup and configuration of the AVR 235, it is simple to operate and enjoy.The following instructions will help you maximize the enjoyment of your new receiver:

Turning the AVR 235 On or Off

• When using the AVR 235 for the first time, you must

press the Main Power Switch1on the front panel to turn the unit on. This places the unit in a Standby mode, as indicated by the amber color of the Power

Indicator2. Once the unit is in Standby, you may begin a listening session by pressing the Standby/On Switch3on the front panel, or the Power On Button d or AVR Selector f on the remote.

The Power Indicator2will turn blue. This will turn the unit on and return it to the input source that was last used. The unit may also be turned on from Standby by pressing any of the Input Selector

Buttons eg on the remote or the Input Source Selector Button^on the front panel.

NOTE: After pressing one of the Input Selector Buttons eg to turn the unit on, press the AVR Selector f to set the remote control to the AVR 235

more than four weeks.

Source Selection

• To select a source, press any of the Input

Buttons eg on the remote.

• The input source may also be changed by pressing

the front-panel Input Source Selector Button ^. Each press of the button will move the input selection through the list of available inputs.

• As the input is changed, the AVR 235 will automati-

cally switch to the digital input (if selected), surround mode, speaker configuration, output levels, crossover frequency and night mode status that were entered during the configuration process for that source.

• The front-panel Video 4 Inputs ÓÔ, Optical 3

Digital Input*or the Coaxial 3 Digital Input

may be used to connect a device such as a video game or camcorder to your home entertainment system on a temporary basis.

• As the input source is changed, the new input name

will appear momentarily as an on-screen display in the lower third of the video display. The input name will also appear in the Upper Display Line ˜ and in the front-panel Input Indicators ı.

• When an audio source is selected, the last video input

used remains routed to the Video 1/Video 2 Video

Outputs eh and Video and S-Video

Monitor Outputs ·j. This permits simultaneous viewing and listening to different sources. This also allows you to choose a video source and then select the 6/8-Channel Direct Inputs g as the audio source.

• When a composite or S-Video source is selected, the

video signal for that input will be routed to the S-Video

Monitor Output·and will be viewable on a TV

monitor connected to the AVR 235.

6-Channel/8-Channel Direct Input

• There are two input choices available for use with sources such as a DVD-Audio or SACD player that are connected to the 6/8-Channel Direct Inputs g. Select the appropriate input according to the way your system and source equipment are configured:

Selector

(

6 CH DIRECT should be used when the SBR and SBL inputs are NOT in use. The AVR 235 operates on the assumption that the input source device has its own internal bassmanagement system. This input passes the input from the source directly through to the volume control without any analog to digital conversion and it mutes the unused input jacks to prevent unwanted noise from interfering with system performance.

8 CH DIRECT should be used when an input is connected to all eight 8-Channel Direct Inputs g. The AVR 235 operates on the assumption that the input source device has its own internal bass-management system. This input passes the input from the source directly through to the volume control without any analogto-digital conversion, and it input jacks to prevent unwanted

mutes the unused

noise from inter-

fering with system performance.

Volume Control

• Adjust the volume to a comfortable level using the

front-panel Volume Control Ù or remote Volume Up/Down Buttons .

• When listening in one of the Stereo modes with the

surround circuits off, the Balance Control Ò may be used to adjust the relative sound output between the front left and right speakers. For all other modes, it is important that the Balance Control Ò remain in the “12 o’clock” position in order to ensure a proper sound field presentation.

• To temporarily silence all speaker outputs, press the

Mute Button . This will interrupt the output to all speakers and the headphone jack, but it will not affect any recording or dubbing that may be in progress. When the system is muted, the word MUTE will flash in the Lower Display Line ¯. Press the Mute Button again to return to normal operation.

• You may adjust the bass and treble tone controls at any point during a listening session by simply turning the Bass Control  or Treble Control Ú until the desired setting is achieved. You may also totally remove the tone controls from the circuit so that the output is “flat” at any time by pressing the

Tone Mode Button 5 and then pressing the Button ) so that TONE OFF appears in the on-screen display and the Lower Display Line ¯.

OPERATION 25

AVR235 harman/kardon

OPERATION

• For private listening, plug the 1/4" stereo phone plug from a pair of stereo headphones into the front-panel Headphone Jack4. When the headphone plug is connected, all speakers will be silenced and DOLBY H:BP will scroll once across the Lower Display Line ¯ , indicating that the headphone output is in the Bypass mode, and to confirm that no processing is being used. When the headphone plug is removed, the audio feed to the speakers will be restored.

• When the headphones are in use, you may take advantage of the Dolby Headphone modes to bring added spaciousness to headphone listening. Press the Dolby Mode Select Button w or the Surround Mode Group Selector 7 to cycle through the three Dolby Headphone modes and select the one that you prefer.

Surround Mode Selection

One of the most important features of the AVR 235 is its ability to reproduce a full multichannel surround sound field from digital sources, analog matrix surround-encoded programs and standard stereo programs.

Selection of a surround mode is based on personal taste, as well as the type of program source material being used. For example, motion pictures or TV programs bearing the logo of one of the major surround-encoding processes, such as Dolby Surround or DTS Stereo, may be played in either the Dolby Digital, Dolby Pro Logic II Cinema, Dolby Pro Logic IIx Cinema, DTS Neo:6 Cinema or Logic 7 Cinema surround modes, depending on the source material.

NOTE: Once a program has been encoded with matrix surround information, it retains the surround information as long as the program is broadcast in stereo. Thus, movies with surround sound may be decoded via any of the analog surround modes such as Dolby Pro Logic II Movie, Logic 7 Cinema or DTS Neo:6 Cinema, when they are broadcast via conventional TV stations, cable, pay-TV and satellite transmission. In addition, a growing number of made-for-television programs, sports broadcasts, radio dramas and music CDs are also recorded in surround sound.

Even when a program is not listed as carrying intentional surround information, you may find that the Dolby Pro Logic II, Logic 7 Enhanced or DTS Neo:6, VMAx and the Hall or Theater modes often deliver enveloping surround presentations through the use of the natural information present in all stereo recordings.

Surround modes may be changed at any time by using either the front panel or remote control. To select a new surround mode from the front panel, first

The Dolby Digital, Dolby Digital EX and DTS 5.1, DTS-ES Matrix and DTS-ES Discrete modes may only be selected when a digital input is in use. In addition, when a digital source is present, the AVR 235 will automatically select and switch to the correct mode, regardless of the mode that has been previously selected. For more information on selecting digital sources, see the Digital Audio Playback section below.

The Dolby Pro Logic IIx modes are available only when the AVR 235 has been configured for 6.1/7.1 operation by configuring the Surround Back speakers as either “Large” or “Small” as described on page 21. These modes provide a matrixed 6.1-channel presentation of analog sources. See page 27 for more information.

When the 6-channel/8-channel direct inputs are in use there is no surround processing, as these inputs take the analog output signals from an optional, external DVD-Audio or SACD player, or another source device and carry them straight through to the volume control without any further digital processing.

Digital Audio Playback

Digital audio is a major advancement over older analog surround processing systems such as Dolby Pro Logic. It delivers five (or six as of this writing) discrete channels: left front, center, right front, left surround and right surround (or back surround, if it is a 6.1-channel format). Each channel reproduces full frequency range (20Hz to 20kHz) and offers dramatically improved dynamic range and significant improvements to signal-to-noise ratios. In addition, digital systems have the capability to deliver an additional channel that is specifically devoted to low-frequency information. This is the “.1” channel referred to when you see these systems described as “5.1,” “6.1” or “7.1.” The bass channel is separate from the other channels, but since it is intentionally bandwidth-limited, sound designers have given it that unique designation.

Dolby Digital

Dolby Digital is a standard part of DVD, and is available on specially encoded LD discs and satellite broadcasts and it is a part of the high-definition television (HDTV) system.

An optional, external RF demodulator is required to use the AVR 235 to listen to the Dolby Digital soundtracks available on laser discs. Connect the RF output of the LD player to the demodulator and then connect the digital output of the demodulator to the Optical or Coaxial Inputs *(ad of the AVR 235. No demodulator is required for use with DVD players or DTS-encoded laser discs.

DTS

DTS is another digital audio system that is capable of delivering 5.1 or 6.1 discrete or matrix sound field reproduction. Although both DTS and Dolby Digital are digital, they use different methods of encoding the signals, and thus they require different decoding circuits to convert the digital signals back to analog.

DTS-encoded soundtracks are available on select DVD and LD discs, as well as on special audio-only DTS discs. You may use any LD or CD player equipped with a digital output to play DTS-encoded discs with the AVR 235. All that is required is to connect the player’s output to either an Optical or Coaxial Input on the rear panel ad or front panel *(.

In order to listen to DVDs encoded with DTS soundtracks, the DVD player must be compatible with the DTS signal as indicated by a DTS logo on the player’s front panel. Early DVD players may not be able to play DTS-encoded DVDs. This does not indicate a problem

The Logic 7 M or Music mode should be used with analog or PCM stereo sources. Logic 7 M enhances the listening experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7 modes also direct low-frequency information to the subwoofer (if installed and configured) to deliver maximum bass impact. The Logic 7 E (or Enhance) mode, available only when the 5.1 option is chosen, is an extension of the Logic 7 mode that is primarily used with musical programs. Logic 7 adds additional bass enhancement that circulates low frequencies in the 40Hz to 120Hz range to the front and surround speakers to deliver a less localized soundstage that appears broader and wider than when the subwoofer is the sole source of bass energy.

OPERATION

with the AVR 235, as some players cannot pass the DTS signal through to the digital outputs. If you are in doubt as to the capability of your DVD player to handle DTS discs, consult the player’s owner’s manual.

IMPORTANT NOTE: Many DVD players have a default setting that does not pass through the DTS data, even though the machine is capable of doing so. If your DVD player has the “DTS Digital Out” logo but does not trigger DTS playback in the AVR 235, change the player’s settings in the “Audio” or “Bitstream"” configuration menu so that DTS playback is enabled. The method for doing this will vary with each player. In some cases, the proper menu choice will be “Original,” while in others it will be “DTS.” Consult the owner’s manual for your player to find the specific information to find the proper setting.

Selecting a Digital Source

To utilize either digital mode, you must have properly connected a digital source to the AVR 235. Connect the digital outputs from DVD players, HDTV receivers, satellite systems or CD players to the Optical or Coaxial Inputs *(ad. In order to provide a backup signal and a source for analog stereo recording, the analog outputs provided on digital source equipment should also be connected to their appropriate inputs on the AVR 235 rear panel (e.g., connect the analog stereo audio output from a DVD to the DVD Audio Inputs k on the rear panel when you connect the source’s digital outputs).

If you have not already configured an input for a digital source using the on-screen menus as shown on pages 17–18, first select the input using the remote or front-panel controls, as outlined in this manual. Next, select the digital source by pressing the

Digital Select Button q# and then using the

any of the OPTICAL or COAXIAL they appear in the Upper Display Line ˜ or onscreen display. When the digital source is playing, the AVR 235 will automatically detect which type of digital data stream is being decoded and display that information in the Upper Display Line ˜.

Digital Bitstream Indications

When a digital source is playing, the AVR 235 senses the type of bitstream data that is present. Using this information, the correct surround mode will automatically be selected. For example, DTS bitstreams will cause the unit to switch to DTS decoding, and Dolby Digital bitstreams will enable Dolby Digital decoding. When the unit senses PCM data from CDs or LDs, you may select any of the standard surround modes, such as Dolby Pro Logic II or Logic 7. Since the range of available surround modes is dependent on the type of digital data that is present, the AVR 235 uses a variety

choose

inputs, as

of indicators to let you know what type of signal is present. This will help you to understand the choice of modes.

When a digital source is playing, the AVR 235 will display a variety of messages to indicate the type of bitstream being received. These messages will appear shortly after an input or surround mode is changed, and they will remain in the Lower Display Line ¯ for about five seconds before that portion of the display returns to the normal surround mode indication.

Surround Mode Types

For Dolby Digital and DTS sources, a three-digit indication will appear, showing the number of channels present in the data. An example of this type of display is 3/2/.1.

The first number indicates how many discrete frontchannel signals are present.

• A “3” tells you that separate front left, center and front right signals are available. This will be displayed for Dolby Digital 5.1 and DTS 5.1 programs.

• A “2” tells you that separate front left and right signals are available, but there is no discrete center channel signal. This will be displayed for Dolby Digital bitstreams that have stereo program material.

• A “1” tells you that there is only a mono channel available in the Dolby Digital bitstream.

The middle number indicates how many discrete surround channel signals are present.

• A “2” tells you that separate surround left and right signals are available. This will be displayed for Dolby Digital 5.1 and DTS 5.1 programs.

• A “1” tells you that there is only a single, surroundencoded surround channel. This will appear for Dolby Digital bitstreams that have matrix encoding.

• A “0” indicates that there is no surround channel information. This will be displayed for two-channel stereo programs.

The last number indicates whether there is a discrete low-frequency effects (LFE) channel. This is the “.1” in the common abbreviation of “5.1” sound and it is a special channel that contains only bass frequencies.

• A “.1” tells you that an LFE channel is present. This will be displayed for Dolby Digital 5.1 and DTS 5.1 programs, as available.

• A “0” indicates that there is no LFE channel information available. However, even when there is no dedicated LFE channel, low-frequency sound will be present at the subwoofer output when the speaker configuration is set to show the presence of a subwoofer.

The information in the right side of the display will tell you if the digital audio data contains a special flag signal that will automatically activate the appropriate 6.1 mode. This will be shown as EX-ON or EX-OFF for Dolby Digital bitstreams, and ES-ON or ES-OFF for DTS bitstreams.

An UNLOCK message may appear in the Lower Display Line ¯. This is your indication that the digital audio data stream has been interrupted or is no longer present. When that occurs, the unit's digital signal processor has no signal to lock onto, and is thus “unlocked.” You may see this message when a DVD is first started until the stream is playing and the processor determines which mode to apply; or any time the data stream is stopped or paused, such as when the menus of some discs are displayed or when the player is switching between the different sections of a disc. You may also see the message when a satellite receiver, cable set-top or HDTV tuner is in use if the digital audio is temporarily interrupted when channels are changed or when a cable box switches from a channel with a digital data stream to a channel with analog audio only. The UNLOCK message is normal, and does not indicate any problem with your receiver. Rather, it tells you that the incoming data has simply been paused or is not present for a variety of possible reasons.

When Dolby Digital 3/2/.1 or DTS 3/2/.1 signals are being played, the AVR will automatically switch to the proper surround mode, and no other processing may be selected. When a Dolby Digital signal with a 3/1/0 or 2/0/0 signal is detected, you may select any of the Dolby surround modes.

It is always a good idea to check the readout for the channel data to make certain that it matches the audio logo information shown on the back of a DVD package. In some cases, you will see an indication for “2/0/0” even when the disc contains a full 5.1, or 3/2/.1, signal. When this happens, check the audio output settings for your DVD player or the audio menu selections for the specific disc being played to make certain that the player is sending the correct signal to the AVR.

PCM Playback Indications

PCM is the abbreviation for Pulse Code Modulation, which is the type of digital signal used for standard CD playback, and other non-Dolby Digital and non-DTS digital sources such as Mini-Disc. When a PCM signal is detected, the Lower Display Line ¯ will briefly show a message with the letters PCM, in addition to a readout of the sampling frequency of the digital signal.

In most cases, this will be 48kHz, though in the case of specially mastered, high-resolution audio discs, you will see a 96kHz indication.

28 OPERATION

AVR235 harman/kardon

OPERATION

Speaker/Channel Indicators

In addition to the bitstream indicators, the AVR 235 features a set of unique channel-input indicators that tell you how many channels of digital information are being received and/or whether the digital signal is interrupted (see Figure 9).

Figure 9

These indicators are the L/C/R/LFE/SL/SR/SBL/SBR letters that are inside the center boxes of the Speaker/ Channel Input Indicators ˆ on the front panel. When a standard analog signal is in use, only the “L” and “R” indicators will light, as left and right channels.

Digital signals, however, may have two, five, six or seven channels, depending on the program material, the method of transmission and the way in which it was encoded. When a digital signal is playing, the letters in these indicators will light in response to the specific signal being received. It is important to note that although Dolby Digital, for example, is referred to as a “5.1” system, not all Dolby Digital DVDs or programs are encoded for 5.1. Thus, it is sometimes normal for a DVD with a Dolby Digital soundtrack to trigger only the “L” and “R” indicators.

NOTE: Many DVD discs are recorded with both “5.1” and “2.0” versions of the same soundtrack. When playing a DVD, always be certain to check the type of material on the disc. Most discs show this information in the form of a listing or icon on the back of the disc jacket. When a disc does offer multiple soundtrack choices, you may have to make some adjustments to your DVD player (usually with the “Audio Select” button or in a menu screen on the disc) to send a full 5.1 feed to the AVR 235. It is also possible for the type of signal feed to change during the course of a DVD playback. In some cases, the previews of special material will only be recorded in 2.0 audio, while the main feature is available in 5.1 audio. The AVR 235 will automatically sense changes to the bitstream and channel count and reflect them in these indicators.

The letters used by the Speaker/Channel Input Indicators ˆ also flash to indicate when a bitstream has been interrupted. This will happen when a digital input source is selected before the playback starts, or when a digital source such as a DVD is paused. The UNLOCK message will also appear on-screen and in the Lower Display Line ¯. The UNLOCK

analog signals have only

message will also appear on screen and in the Lower Display Line ¯. The flashing indicators remind you that the playback has stopped due to the absence of a digital signal and not through any fault of the AVR 235. This is normal, and the digital playback will resume once the playback is started again.

Night Mode

A special feature of Dolby Digital is the Night mode, which enables specially encoded Dolby Digital input sources to be played back with full digital intelligibility while reducing the minimum peak level by 1/4 to 1/3. This prevents abruptly loud transitions from disturbing others, without reducing the impact of the digital source. The Night mode is available only when Dolby Digital signals with special data are being played.

The Night mode may be engaged when a Dolby Digital DVD is playing by pressing the Night Mode

Button l on the remote. Next, press the Buttons n to select either the middle range or

full-compression versions of the Night mode. To turn the Night mode off, press the until the message in the lower third of the video display and in the Lower Display Line ¯ reads D-RANGE OFF.

The Night mode may also be selected to always be on at either level of compression using the options in the DOLBY menu. See page 19 for information on using the menus to set this option.

IMPORTANT NOTES ON DIGITAL PLAYBACK:

• When the digital playback source is stopped, or in a pause, fast forward or chapter search mode, the digital audio data will momentarily stop, and the channel position letters inside the Speaker/ Channel Input Indicators ˆ will flash. The UNLOCK message will also appear on-screen and in the Lower Display Line ¯. This is normal and does not indicate a problem with either the AVR 235 or the source machine. The AVR 235 will return to digital playback as soon as the data is available and when the machine is in a standard play mode.

• Although the AVR 235 will decode virtually all current DVD movies, CDs and HDTV sources, it is possible that some future digital sources may not be compatible with the AVR 235.

• Not all digitally encoded programs contain full 5.1or 6.1-channel audio. Consult the program guide that accompanies the DVD or laser disc to determine which type of audio has been recorded on the disc. The AVR 235 will automatically sense the type of digital surround encoding used and adjust to accommodate it.

Recording

In normal operation, the audio or video source selected for listening through the AVR 235 is sent to the record outputs. This means that any program you are watching or listening to may be recorded simply by placing machines connected to the Tape Outputs

™ or Video 1/Video 2 Audio and Video Outputs eh in the Record mode.

When a digital audio recorder is connected to the Digital Audio Outputs ‡°, you are able to record the digital signal using a CD-R, MiniDisc or other digital recording system.

NOTES:

• The digital outputs are active only when a digital signal is present, and they do not convert an analog input to a digital signal, or change the format of the digital signal. In addition, the digital recorder must be compatible with the output signal. For example, the PCM digital input from a CD player may be recorded on a CD-R or MiniDisc, but Dolby Digital or DTS signals may not.

• Please make certain that you are aware of any copyright restrictions on any material you copy. Unauthorized duplication of copyrighted materials is prohibited by federal law.

Output Level Trim Adjustment

Normal output level adjustment for the AVR 235 is established using the test tone, as outlined on pages 23–24. In some cases, however, it may be desirable to adjust the output levels using program material such as a test disc, or a selection you are familiar with. Additionally, the output level for the subwoofer can only be adjusted using this procedure.

To adjust the output levels using program material, first set the reference volume for the front left and front right channels using the Volume Control Ù

If you are using a disc with test signals or an external signal generator as the source from which to trim the output levels, you may use the EzSet feature of the remote to guide you to the correct SPL level. To use the remote for this purpose, press and quickly release the SPL Selector Button to activate the sensor.

While the test tone is circulating, the Program/SPL Indicator c will change color to indicate the level.

Adjust the level using the

Processor Reset

In the rare case in which the unit’s operation or the displays seem abnormal, the cause may involve the erratic operation of the system’s memory or microprocessor.

To correct this problem, first unplug the unit from the AC wall outlet and wait at least three minutes. After the pause, reconnect the AC power cord and check the unit’s operation. If the system still malfunctions, a system reset may clear the problem.

To clear the AVR 235’s entire system memory including tuner presets, output level settings, delay times and speaker configuration data, press and hold the Tone Mode Button 5 buttons for three seconds. The unit will turn on automatically.

NOTE: Resetting the processor will erase any configuration settings you have made for speakers, output levels, surround modes and digital input assignments, as well as the tuner presets. The unit will be returned to the factory presets, and all settings for these items must be reentered.

If the system is still operating incorrectly, there may have been an electronic discharge or severe AC line interference that has corrupted the memory or microprocessor.

If these steps do not solve the problem, consult an authorized Harman Kardon service center.
