Introduction

1

Congratulations!

With the purchase of a Harman Kardon AVR75 you are about to begin many years of listening enjoyment. The AVR75 has been custom designed to provide all the excitement and detail of movie soundtracks and every subtle nuance of musical selections. With on board Dolby

*

Digital

Decoding, the AVR75 delivers six discrete channels of audio that take advantage of the digital soundtracks from the latest

DVD and LV releases.

While complex digital systems are hard at work within the AVR75 to make all of this happen, hook-up and operation are simple. Color-keyed connections, a comprehensive remote control and on-screen menus make the AVR75 easy to use. To obtain the maximum enjoyment from your new receiver we urge you to take a few minutes to read through this manual.

This will ensure that connections to speakers, source playback units and other external devices are made properly. In addition, a few minutes spent learning the functions of the various controls will enable you to take advantage of all the power the AVR75 is able to deliver.

If you have any questions about this product, its installation or operation, please contact your retailer or custom installer. They are your best local source of information.

Description and Features

The AVR75 is a full-featured A/V receiver, incorporating a wide variety of listening options. In addition to Dolby Digital decoding, Dolby Pro Logic

* and Dolby 3

Stereo are available for compatibility with the tens of thousands of movies and television programs encoded with analog surround information. A choice of Hall,

Matrix and Movie modes is also available for use with both encoded sources and traditional two-channel stereo recordings.

A total of five audio/video inputs, each with both composite and S-Video, as well as three additional audio only inputs are selected through a learning remote control and an easy to read front panel display or on-screen graphics through a TV monitor.

The AVR75’s powerful amplifier uses traditional Harman Kardon High Current design philosophies to meet the wide dynamic range of any program selection.

Harman Kardon invented the highfidelity receiver over forty years ago.

With state-of-the-art circuitry and timehonored circuit designs, the AVR75 is undoubtedly the finest receiver ever offered by Harman Kardon.

Important Safety Information

Verify Line Voltage Before Use

Your AVR75 has been designed for use with 120-volt AC current. Connection to a line voltage other than that for which it is intended can create a safety and fire hazard, and may damage the unit.

If you have any questions about the voltage requirements for your specific model, or about the line voltage in your area, contact your selling dealer before plugging the unit into a wall outlet.

Do Not Use Extension Cords

To avoid safety hazards, use only the power cord attached to your unit. We do not recommend that extension cords be used with this product. As with all electrical devices, do not run power cords under rugs or carpets or place heavy objects on them. Damaged power cords should be replaced immediately with cords meeting factory specifications.

Handle the AC Power Cord Gently

When disconnecting the power cord from an AC outlet, always pull the plug, never pull the cord. If you do not intend to use the unit for any considerable length of time, disconnect the plug from the AC outlet.

Do Not Open The Cabinet

There are no user-serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modification to the product will void your guarantee. If water or any metal object such as a paper clip, wire or a staple accidentally falls inside the unit, disconnect it from the AC power source immediately, and consult an authorized service station.

CATV or Antenna Grounding

If an outside antenna or cable system is connected to this product, be certain that it is grounded so as to provide some protection against voltage surges and static charges. Section 810 of the National

Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the leadin wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes and requirements of the grounding electrode.

NOTE TO CATV SYSTEM INSTALLER:

This reminder is provided to call the

CATV (Cable TV) system installer’s attention to article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as possible.

Installation Location

■

To assure proper operation, and to avoid the potential for safety hazards, place the unit on a firm and level surface. When placing the unit on a shelf, be certain that the shelf and any mounting hardware can support the weight of the product.

■

Make certain that proper space is provided both above and below the unit for ventilation. If this product will be installed in a cabinet or other enclosed area, make certain that there is sufficient air movement within the cabinet.

Under some circumstances a fan may be required.

■

Do not place the unit directly on a carpeted surface.

■

Avoid installation in extremely hot or cold locations, or an area that is exposed to direct sunlight or heating equipment.

■

Avoid moist or humid locations.

■

Do not obstruct the ventilation slots on the top of the unit, or place objects directly over them.

Cleaning

When the unit gets dirty, wipe it with a clean, soft dry cloth. If necessary, wipe it with a soft cloth dampened with mild soapy water, then a fresh cloth with clean water. Wipe dry immediately with a dry cloth. NEVER use benzene, aerosol cleaners, thinner, alcohol or any other volatile cleaning agent. Do not use abrasive cleaners, as they may damage the finish of metal parts. Avoid spraying insecticide near the unit.

Moving The Unit

Before moving the unit, be certain to disconnect any interconnection cords with other components, and make certain that you disconnect the unit from the AC outlet.

Unpacking and Installation

The carton and shipping materials used to protect your new receiver during shipment were specially designed to cushion it from shock and vibration. We suggest that you save the carton and packing materials for use in shipping if you move or should the unit ever need repair.

To minimize the size of the carton in storage, you may wish to flatten it. This is done by carefully slitting the tape seams on the bottom and collapsing the carton down to a more two-dimensional appearance. Other cardboard inserts may be stored in the same manner. Packing materials that cannot be collapsed should be saved along with the carton in a plastic bag.

If you do not wish to save the packaging materials, please note that the carton and other sections of the shipping protection are recyclable. Please respect the environment and discard those materials at a local recycling center.

Installation and Setup

13

System Installation

After unpacking the unit, 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. These steps need to be done only when the receiver is first installed, or when a change is made to the input source equipment.

Audio Input and Output Connections

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

When making connections to audio source equipment or speakers it is always a good practice to unplug the unit from the AC wall plug. This prevents any possibility of accidentally sending audio or transient signals to the speakers that may damage them.

1. For playback only audio sources, such as a CD player, CD changer, external phono preamp or external digital to analog converter, connect the output jacks of the player to the appropriately labeled inputs on the rear panel

•

.

NOTE: When the source device has both fixed and variable 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 high that the signal is distorted.

2. When connecting recording devices such as audio cassette recorders, open reel audio tape decks, DCC, DAT or MD, connect the PLAY/OUT jacks of the recorder to the

Tape In

jacks

¢ § on the AVR75. Connect the RECORD/IN jacks on the recorder to the

Tape Out

jacks £ ∞ on the AVR75.

3. Connect the output of any digital sources to be used to the appropriate connections on the AVR75 rear panel.

Note that the

Optical

and

Coaxial

digital inputs

°· may be used with either a Dolby Digital (AC-3) source or the output of a conventional CD or

LV player’s PCM (SP/DIF) output. The

AC-3 RF

input a may ONLY be connected to the special AC-3 RF output of a laser disc player.

4. Assemble the AM Loop Antenna supplied with the unit as shown below.

Connect it to the

AM

and

GND

screw terminals

¡

.

5. Connect an 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. Note that if the antenna or connection uses 300-ohm twin lead cable, you must use the 300-ohm to

75-ohm adapter supplied with the unit to make the connection.

6. Connect the front, center and surround speaker outputs

¤‹› to the respective speakers.

To assure 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 this 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 fine, multistrand copper with a gauge of 14 or larger. 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 ten 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 electrical contractor who is familiar with the NEC and/or the applicable local building codes in your area.

AVR75 om (c) 9/16/98 11:33 AM Page 14

Installation and Setup

14

When connecting wires to the speakers, be certain to observe proper polarity.

Remember to connect the “negative” or

“black” wire to the same terminal on the receiver and the speaker. Similarly, the

“positive” or “red” wire should be connected to the like terminal on the AVR75 and speaker.

Note: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configuration. To assure 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.

7. Connections to a subwoofer are made via a line level audio connection from the

Subwoofer Output

⁄ to the line level input of a subwoofer with a built-in amplifier. If a passive subwoofer is used, the connection first goes to a power amplifier, which will be connected to one or more subwoofer speakers.

Video Input and Output Connections

Video connections are made in a similar fashion to those for audio components.

Again, the use of high-quality interconnect cables is recommended to preserve signal quality.

1. Connect the VCR’s audio, video and

S-Video OUT jacks to the

Video In

jacks d i on the rear panel. The audio, video and S-Video IN jacks on the VCR should be connected to the

Video Out

jacks e h on the AVR75.

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

TV

jacks ª .

3. Connect the audio, video and S-Video outputs of a DVD or laser disc player to the

DVD

jacks • .

4. Connect the

TV Mon

f g jacks on the receiver to the video, or S-Video inputs, of your television monitor or video projector.

5. As the AVR75 does not mix or change between standard composite video and

S-Video signals, both monitor connections must be made if you use both signal systems.

Note: The on-screen menus are visible on the composite video output only.

System and Power Connections

The AVR75 is designed for flexible use with external control components and power amplifiers. These connections are easy to make during an initial installation, or at a later date should you choose to upgrade your system.

Remote Control Extension

If the receiver is placed behind a solid or smoked glass cabinet door, the obstruction may prevent the remote sensor from receiving commands. In this event, an optional remote sensor may be used.

Connect the output of the remote sensor to the

Remote Cont. In

jack b .

If other components are also prevented from receiving remote commands, only one sensor is needed. They may use this unit’s sensor or a remote eye by running a connection from the

Remote Cont.

Out

jack c to the Remote In jack on

Harman Kardon or other compatible equipment.

External Audio Power

Amplifier Connections

If desired, optional external power audio power amplifiers may be used with the

AVR75. Connections to these amplifiers are made by using audio interconnect cables connected to both the

Preamp

Outputs

‚ on the rear panel and the audio input jacks of the external amplifiers.

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 may not exceed 50w to each outlet.

The

Switched

fi outlet 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: Devices with electronic power switches may only go into a Standby mode when plugged in here.

The

Unswitched

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

Finally, when all connections are complete, plug the power cord into a nonswitched 120-volt AC wall outlet. You’re almost ready to enjoy the AVR75!

Remote Control Programming and Operation

15

This product is equipped with a powerful remote control. As supplied, it will operate the receiver, as well as most CD players and tape decks manufactured by Harman

Kardon. If your equipment requires different codes, it may be programmed to copy the codes from most infrared remotes.

Loading Batteries

The life of the batteries for the remote control is about one year in normal operation. If the amber

Sending

indicator does not flash when remote buttons are pushed, that is an indication that the batteries need to be replaced.

To change the batteries:

1. Remove the back cover by sliding it in the direction of the arrows.

3. Close the cover until it clicks shut.

NOTE: It is important that the batteries be replaced within ten minutes after the old batteries are removed to avoid losing any remote codes that have been programmed into the remote’s memory.

Remote Control Range

The remote will operate at a range of up to 15 feet from the unit, when the batteries are fully charged. The remote will also operate at an angle of up to 30° to either side of the unit.

2. Remove the old batteries and insert fresh AAA type cells. Be certain to observe the correct polarity by noting the (+) and (–) marks on both the inside of the case and on the battery cells. It is recommended that both batteries be changed at the same time.

Always point the remote transmitter at the front of the unit when issuing commands. If you find that remote commands are not being received by the remote, it may be necessary to use a remote IR sensor.

Remote Programming

Programmable Keys

Many of the buttons on the remote control may be user programmed to new functions to operate virtually any component in your system. Eleven CANNOT be programmed with a new code, as they control high-level functions of the

AVR75. These keys are

Main Power ON

,

Main Power OFF

System Configuration

17

When all audio, video and system connections have been made, there are a few configuration adjustments to be made. A few minutes spent to correctly configure and calibrate the unit will greatly add to your listening experience.

Speaker Selection

The placement of speakers in a multichannel home theater system can have a noticeable impact on the quality of sound reproduced.

No matter which type or brand of speakers is used, the same model or brand of speaker should be used for the front left, center and right speakers. This creates a seamless front soundstage, and eliminates the possibility of distracting sonic disturbances that occur when a sound moves across mismatched front channel speakers.

Speaker Placement

Depending on the type of center channel speaker in use and your viewing device, place the center speaker directly above or below your TV or in the center behind a perforated front projection screen.

Once the center channel speaker is installed, position the left and right front speakers so that they are as far away from one another as the center channel speaker is from the preferred listening position. Ideally, the front channel speakers should be placed so that their tweeters are no more than 24

″ off center from the tweeter in the center channel speaker.

Depending on the specifics of your room acoustics and the type of speakers in use, you may find that imaging is improved by moving the front left and right speakers slightly forward of the center channel speaker. If possible, adjust all front loudspeakers so that they are aimed at ear height when you are seated in the listening position.

Using these guidelines, you’ll find that it takes some experimentation to find the correct location for the front speakers in your particular installation. Don’t be afraid to move things around until the system sounds correct. Optimize your speakers so that pans across the front of the room sound smooth, and that sounds from all speakers appear to arrive at the listening position at the same time without delay from the center speaker as opposed to the left and right speakers.

Surround speakers should be placed on the side walls of the room, at or slightly behind the listening position. The center of the speaker should face into the room.

The speakers should be located so that the bottom of the cabinet is at least two feet higher than the listeners’ ears when in the desired area.

If side wall mounting is not practical, the speakers may be placed on a rear wall, behind the listening position. Again, they should be located so that the bottom of the cabinet is at least two feet higher than the listeners’ ears. The speakers should be no more than six feet behind the rear of the seating area.

Subwoofers produce non-directional sound, so they may be placed almost anywhere in a room. Subwoofer placement is highly influenced by room size and shape, and the type of subwoofer used. Follow the instructions of the subwoofer’s manufacturer, or experiment with the best location for a subwoofer in your listening room.

7.

SET UP MENU 1 enters the information that tells the AVR75 which type of front and surround speakers will be used. In turn, these settings will determine which speakers receive low frequency (bass) information. For the purposes of establishing proper bass reproduction, use the

LARGE settings if the speaker being used at any position is a traditional full-range loudspeaker that is capable of reproducing sounds below 100Hz. Use the

SMALL setting for smaller, frequency-limited satellite speakers that are not able to reproduce sounds below 100Hz. Note that when

“small” speakers are used it is advisable to install a separate subwoofer.

8. Enter the information for the

FRONT

AVR75 om (c) 9/16/98 11:33 AM Page 21

Basic Operation

21

Once the input source, speaker and antenna connections have been made, and the system has been configured, the receiver is ready for operation. Note that some controls are duplicated on both the front panel and the remote control, while others appear on one or the other, but not both.

Power Switch

To turn the AVR75 on for the first time, press the front panel

Power

button

1

.

When you press the

Power

button note that the LED indicator surrounding the switch will momentarily turn red, then green indicating that the unit has been turned on. If the unit is connected to a TV set a brief status report (see figure #6) of the AVR75’s settings will momentarily appear.

Once the unit has been turned on with the front panel switch it may then be placed in a Standby mode for future use using the

Main Power On

c button on the remote. Note that the remote power will NOT operate unless the

Power

button has first been manually depressed.

When the AVR75 is turned off using the remote control it is placed in a

STANDBY mode, and the Standby LED surrounding the

Power

switch will illuminate in amber. The AVR75 may be turned on by pressing either the

Main Power On

button c or any of the

24578)!

or one of the

Source

buttons on the remote d

.

Each time the source is changed a message (see figure #7) will appear briefly if the on-screen display is activated confirming the new selection.

To listen to one source while you watch another, first select the video source, and then select the desired audio source.

NOTE: When the unit is in “Standby” mode, pressing any of the source buttons will turn on the unit.

The video source will be shown next to the word

VISUAL

in the

Visual

Indicator

P in the

Information

Display

ı

. The audio source, which may be the same or different than the video source will always be shown in the

Main Information Display

J .

Volume Control

The AVR75’s volume is controlled using either the front panel

Volume

knob

Ù or the

Volume

buttons o on the remote.

If the volume control is set too high, a speaker overload may activate the unit’s protective circuitry. This will cut the output to the speakers and change the LED surrounding the power switch to a red color. To clear the problem, turn the unit off for a few seconds, and lower the volume before turning it back on. If the problem re-occurs, turn the unit off and consult your dealer or an authorized service center for advice.

NOTE: Unlike conventional mechanically driven volume controls, this receiver’s volume is set using digital devices. This means that the volume knob has no firm stopping point at either end of its rotation.

Depending on the speed with which the knob is turned, it is normal for as many as three complete rotations to be required for full travel from the loudest setting to the softest.

When the volume is adjusted the change will be indicated by an on-screen display

(see figure #8). The word

MASTER will also appear in the main portion of the

Information Display

ı , followed by a two-digit number. The number indicates the variation from the reference point established when the output levels are set.

Surround Mode Selection

One of the most important features of the AVR75 is its ability to reproduce a full multichannel surround soundfield from

Dolby Digital sources, analog matrix surround encoded programs, and standard stereo programs. In all a total of seven listening modes are available.

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 bearing the logo of one of the major surround encoding processes, such as Dolby

Digital, Dolby Surround, DTS

†

Stereo or

UltraStereo

†† may be played in either the

Dolby Digital, Dolby Pro Logic or Movie

Surround depending on the source material. TV or radio broadcasts of programs in surround should normally be played back in the Dolby Pro Logic or

Movie Surround modes. Other mode selections are described elsewhere in this manual.

AVR75 120 rev (c) 8/27/97

AVR75 om (c) 9/16/98 11:33 AM Page 22

Basic Operation

22

NOTE: Once a program has been encoded with surround information, it retains the surround matrix as long as the program is broadcast in stereo. Thus, movies with surround sound will carry surround information 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. You may obtain a list of these programs and discs from the Dolby

Laboratories web site at www.dolby.com

Surround modes may be selected in one of three ways.

From the front panel, use the

Mode

⁄ or

Mode

¤ buttons

@ to scroll through the list of modes. The selected mode will appear in large letters in the front panel display, and in a two-line reminder on the video screen. Once the selection is made, the mode will continue to appear in a smaller indicator

B at the bottom of the front panel display

(see figure 9).

From the remote, modes may be selected by simply pressing the button y that corresponds to the desired mode.

Modes may also be selected using the on-screen display. Press

Select

j on the remote to display the

MAIN MENU

.

Then press

¤ i so that the on-screen cursor is next to

SURROUND MODE

.

Press

Select

j again to move to the next menu.

At the Surround Mode Menu, press the

‹ or

› buttons i until the desired mode name appears on the screen. Press

¤ until the on-screen cursor

> is next to

RETURN TO MAIN MENU and press

Select

j

. At the main menu select

MENU OFF and press

Select

j to exit the menus.

A different mode may be selected for audio and video sources. Once a mode has been selected, it will be attached to those sources in memory. Thus, you may select

PRO LOGIC as the mode for one video source and

HALL for another.

After the initial selections are made, the unit will automatically return to your preferred mode for each type of input whenever it is chosen.

Digital Audio Sources

When the source is connected to the

AVR75 and playing digital audio information, first select it using the front panel or remote input selectors, and then press the appropriate digital input using the

Digital Input Selectors

g 9 on the remote or front panel. Depending on the type of digital source in use, the

AC-3 indicator

A will light when a

Dolby Digital signal is present, or the

PCM indicator

Q will light when a standard two-channel S/P-DIF-type digital signal is present.

Once a Dolby Digital signal is detected the unit will automatically switch to the

Dolby Digital mode. When a PCM digital source is detected you may select any of the surround modes except Dolby Digital.

NOTE: The Dolby Digital mode should not be selected when PCM digital or analog signals are present. If the Dolby

Digital mode is selected when an AC-3 signal is not detected, the AVR75 will default to the

STEREO mode.

For information on using Digital Audio

Sources, see the Advanced Features section of this manual.

IMPORTANT NOTE:

Many people incorrectly presume that sound should always be heard from the surround channels. In reality, it is normal for the surround channels to operate occasionally, and often to be silent. Movie directors and sound mixers typically use these channels only when needed to create an effect or establish ambience.

Artificially increasing the volume level to the surround channels may destroy the illusion of surround audio and add unwanted noise to your system.

Tuner Operation

The AM/FM tuner is extremely flexible, and offers a number of options. The following instructions will enable you to take advantage of the tuner’s many features.

To select tuner operation, press the

AM/FM

button

2 on the front panel, or the remote h . Press the button again to select the desired frequency band if required.

Up/down tuning is accessible by pressing the

Tune

button Ò on the front panel either up

⁄ or down

¤ or the

‚

TUNE /SEARCH

— buttons s on the remote. Pressing these buttons once increases or decreases the station frequency by one step.

Holding the buttons down quickly scans for the next station. Holding the tune buttons for a few seconds and then releasing them will change the tuner to the next station with an acceptable signal.

Advanced Features

28

In addition to basic audio functions, this receiver is capable of audio/video dubbing and a wide range of surround modes. Advanced digital decoding and signal processing provides specialized surround modes that are compatible with virtually all types of music software and movie soundtracks.

Audio Tape Dubbing

The input directed to the audio and video record outputs

£ ∞ e h is normally the source currently selected for listening through the AVR75. If you are using a tape recorder or cassette deck with three heads and wish to listen to the “off tape” playback to verify the recording, press the front panel

T-Mon

button 5 or the

Tape 1

d button on the remote until the red light over

T-Mon

on the front panel illuminates. You will then hear the source as it is being recorded and played back through your tape machine. The source will be verified in both the front panel and on-screen displays. Note that the video surrounding the word

AUDIO will turn white to indicate that you are in the Tape Monitor mode.

Audio/Video Simulcast

Operation

It is possible to watch and listen to, or record the video from one source along with the audio from a different input.

This is useful in the case of musical programs where the sound is being broadcast via FM, or for sports events where you wish to have the picture from a TV station, but the play-by-play from a radio station.

For simulcast operation first select the video source input using the input selection buttons on the remote control or front panel

8)!d

. Next, select the audio source

2457d

. Note that the on-screen menu display will show the split sources (see figure #7). The front panel display will show the audio source in large letters in the main portion of the

Information Display

J

, while the video source will appear in smaller letters next to the

Visual

indicator

P

.

TV Auto Function

With the increasing sophistication of today’s home entertainment systems, it often takes numerous remote controls to turn on all components in a system. This receiver’s unique “TV Auto On” function greatly simplifies that task and reduces the actions needed to bring your entire system to life.

If you are using a TV or projector that has a video output, connect the TV’s audio and video outputs to the rear panel of the

AVR75 ª . Once those connections have been made and the feature is turned on, the AVR75 will automatically turn on whenever the TV set is on, thanks to a video-sensing circuit in the AVR75. This eliminates the need to turn the unit on separately from the TV.

As long as the TV is on and feeding a video signal, the AVR75 will remain on.

If no other input source is selected and the TV is turned off, the AVR75 will turn off approximately five minutes after the

TV set.

This feature is turned off in the AVR75’s factory configuration and must be turned on using the following steps:

1. Press the front panel

Mode

⁄ button

@

.

2. While holding the Mode button, press the

TV

button

8 for at least 5 seconds until the

Main Information Display

J display reads

TV AT OFF

.

3. Release both buttons and immediately press the

TV

button

8 again until the display reads

TV AT ON

.

If you select another input, such as CD or the AM/FM tuner after the unit has turned on, it will remain on even if the

TV is turned off. You must then turn the receiver off using the front panel or remote

Power

buttons 1c .

NOTE: The TV Auto On Function will only respond to conventional video signals. It will NOT operate with S-Video.

If, at some future point you wish to disable this feature, follow the steps outlined above but press the

TV

button 8 as shown in step #3 so that the display reads

TV AT OFF

.

Delay Time Adjust

One aspect of the surround modes is the delay of audio signals between the front speakers and the rear speakers. Each surround mode is factory preset with a specific delay time, but it is possible to individually adjust the delay timing to custom tailor the sound to your individual taste and the acoustic conditions in your listening room or home theater.

The factory setting is appropriate for most rooms, but some installations create an uncommon distance between the front and surround speakers that may cause the arrival of front channel sounds to become disconnected from surround channel sounds.

To resynchronize the front and surround channels, follow these steps:

1. Measure the distance from the listening/viewing position to the front speakers.

2. Measure the distance from the listening/viewing position to the surround speakers.

AVR75 120 rev (c) 8/27/97

AVR75 om (c) 9/16/98 11:33 AM Page 29

Advanced Features

29

3. Subtract the distance to the surround speakers from the distance to the front speakers.

a. When setting the delay time for the Dolby Digital surround mode, the optimal delay time is the resulting figure. For example, if the front speakers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as 10-5=5. Thus, in this example, the delay should be set at five milliseconds.

b. When setting the delay time for an analog surround mode (Pro

Logic, Hall, Movie or Matrix) take the result of the subtraction and add 15 to obtain the optimal delay time. For example, if the front speakers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as 10-5+15=20. Thus in this example, the delay should be set at twenty milliseconds.

The Dolby Digital mode also provides a separate setting for the center channel delay mode, since the discrete nature of Dolby Digital signals makes the location of the center channel speaker more critical. To set the delay for the center channel, measure the distance from the preferred listening position in the center of the room to both the center channel speaker and either the left or right speaker.

If the distances are equal no further adjustment is required and the center delay should be set to zero. If the distance to the front speakers is greater than the distance to the center speaker you may wish to reposition the speakers by moving the front left/right speakers closer to the listening position or the center speaker further away from the listening position.

If repositioning of the speakers is not possible, adjust the center delay time so that you add one millisecond of center channel delay for each foot that the distance to the center speaker lags behind the front speakers. For example, if the front left/right speakers are each 10 feet from the listening position and the center channel speaker is 8 feet away, the delay is figured as 10-8=2, suggesting an optimal center delay of 2 milliseconds.

The factory settings for the delay times are shown in the chart on page 31. If the use of the formulas described above or your own experimentation and preferences suggest that the delay time be changed, the adjustment is made from the

SURROUND MODE menu.

Reach the menu by pressing

Select

j and then pressing the

¤ button i once so that the on-screen cursor

> is next to the

SURROUND MODE line and then press

Select

again. The

SUR-

ROUND MODE menu (see figure #15) will then appear. If you wish to change the surround mode before proceeding, use the

‹ or

› buttons i until the desired mode is highlighted in reverse video. Next press the

¤ button so that the cursor is next to

CENTER CH or

SURROUND CH

. (Note that center channel delay may only be adjusted in

Dolby Digital mode.) Press the

› button i until the desired time is highlighted in reverse video and then press

¤ until the cursor is next to

RETURN TO

MAIN MENU and press

Select

j

.

Other adjustments may now be made, or move the cursor to

MENU OFF and press

Select

to exit the menu system.

Digital Audio Playback

Dolby Digital

Dolby Digital (also known as AC-3) is the latest advancement in surround sound technology, delivering up to five fullrange surround channels (left, center, right, left surround and right surround) plus a special dedicated Low-Frequency

Effects (LFE) channel. This represents a major advancement over traditional analog surround in that each surround channel is fully discrete and capable of full bandwidth reproduction. Dolby

Digital is available on DVD and LV discs, and it will be a part of the new high definition television (HDTV) system when digital broadcasting begins in

1998. Dolby Digital for the home is based on the same system used to deliver digital audio soundtracks in movie theaters, enabling true cinema reproduction in your home.

To utilize the Dolby Digital mode you must have a digital source properly connected to the AVR75. The RF digital output of a laser disc player should be connected to the

AC-3 RF

jack a on the rear panel. Note that this jack is for use

only

with the RF output from an LV player and should not be connected to any other audio, video or digital device.

Digital datastream outputs from DVD players, HDTV receivers and CD players should be connected to the

AC-3/PCM

Optical

or

Coaxial

inputs on the rear panel ° · . In order to provide a backup signal and a source for recording, the analog outputs provided on digital source equipment should also be connected to their appropriate inputs on the

AVR75 rear panel. (e.g., connect the analog stereo audio output from a DVD to the

DVD

inputs

• on the rear panel when you connect the digital outputs).

When playing back a digital source, first select the input using the remote or front panel controls d48)!

. Next select the digital source by pressing the appropriate

Digital Input

button

9g

. When the digital source is playing, the AVR75 will automatically detect

When an AC-3 source is playing the

AVR75 will automatically switch to the

Dolby Digital surround mode. It is important to note, however, that not all

AC-3 sources are encoded with the full complement of five channels plus LFE.

When an AC-3 source is playing the

3/2.1:

This message appears when a full complement of Dolby

Digital signals is present: 3 front channels (left, center and right),

2 surround channels (surround left and surround right) and “1” channel, which is the dedicated Low

Frequency Effects (LFE) channel.

3/1:

This message indicates the

AC-3 system is decoding a standard

Dolby Pro Logic signal with left, center and right front channels and a single mono surround channel.

2/0:

This message indicates that the AC-3 system is decoding a traditional two-channel stereo signal and that no center, surround or LFE signals are present.

Night Mode

A special feature of Dolby Digital is the

Night mode, which enables AC-3 input sources to be played back with their full range while reducing the minimum peak level by

1/4 to

1/3

. This prevents abruptly loud transitions from causing disturbances without reducing the impact of the digital source. The Night mode is available only when AC-3 signals with special data are being played.

To engage the Night mode, press the

Night

button

6 e on the front panel or remote and note that

Night

indicator

E will illuminate. The Night mode may also be turned on through

SETUP

MENU 3

.

IMPORTANT NOTES ON

DOLBY DIGITAL PLAYBACK:

1. When the playback unit is in a pause, fast forward or chapter search mode the digital audio data may momentarily stop, causing a

NO DATA message to be displayed. This is normal and does not indicate a problem with either the AVR75 or the source machine. The AVR75 will return to Dolby Digital/AC-3 playback as soon as the data is available when the machine is in a standard play mode.

2. If a digital source is being played and you switch to another input the

AVR75 will revert to the analog input when you once again select the prior source. For example, if a DVD is playing with coax digital audio and you switch to TV and then back to DVD, the DVD’s analog audio will play when you return to that source. The digital input MUST be selected each time you wish to use it, even if it was in use the last time that source was playing.

3. The AVR75 will decode digital audio sources with a sampling frequency of

32kHz, 44.1kHz and 48kHz. Although this will enable it to decode virtually all

DVD movies and HDTV sources, it is possible that some digital sources may not be compatible with the AVR75.

4. The AVR75 will automatically detect most Dolby Digital and PCM digital audio sources and switch to the proper surround mode. It is possible, however, that future source equipment that could not be anticipated at this time, may require manual surround mode selection using the

Surround Mode Selectors

@ y .

PCM Audio Playback

PCM (Pulse Code Modulation) is the non-compressed digital audio system used for conventional compact discs and non-AC-3 laser discs. The digital circuits in the AVR75 are capable of high-quality digital-to-analog decoding, and they may be connected directly to the digital audio output of your CD or LV player.

Connections should be made to the

AC-3/PCM Optical

or

Coaxial

inputs

° · on the rear panel, using whichever input is not occupied by an AC-3 source such as a DVD player.

To listen to a PCM digital source first select the analog input (e.g., CD) and then press the desired

Digital Input

button

9g

. Indicators will light to confirm that

PCM

data is being received

Q and if the

Optical

or

Coaxial

input C is the source. The

This mode is used only when the source material is encoded with Dolby Digital (AC-3) data. It provides up to five separate main audio channels and a special dedicated Low-

Frequency Effects channel. Use this mode with DVD, LV or HDTV sources featuring

Dolby Digital playback.

Center: 0 ms – 5 ms

Surround: 0 ms – 15 ms

Dolby Pro Logic is the standard mode for surround sound decoding. It uses information encoded in a two-channel stereo recording to produce four distinct channels: Left, Center, Right and Surround. Use this mode for accurate reproduction of programs bearing the Dolby Surround, DTS Stereo, UltraStereo or other

“Surround” logos. Surround encoded programs include videocassette, DVD and LD movies, TV and cable programs, radio programs and audio CDs. Dolby Pro Logic processing may also be used to provide a pleasing surround effect with some stereophonic source material that does not carry surround encoding.

15 ms – 30 ms

Initial Setting = 20 ms

Dolby 3 Stereo uses the information contained in a surround encoded or two-channel stereo program to create center channel information. In addition, the information that is normally sent to the rear channel surround speakers is carefully mixed in with the front left and right channels for increased realism. Use this mode when you have a center channel speaker, but no surround speakers.

No Surround Channels

Movie Surround processing uses matrix surround decoding, with the option to extend the delay time to 90 ms. Use this to experiment with surround times above 30 ms, or if the delay time formula suggests a longer time delay for your room.

40 ms – 90 ms

Initial Setting = 40 ms

This mode is designed for use with stereo recordings. It provides a sound-field effect that simulates the complex combination of direct and reflected sounds that create the rich reverberant atmosphere of a medium-sized circular concert hall.
