Introduction

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.
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 tele-
vision 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.

porting structure, grounding of the lead-
in 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.
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.
NOTE TO CATV SYSTEM INSTALLER:
This reminder is provided to call the
CATV (Cable TV)system installer’s atten-
tion 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 ground-
ing system of the building, as close to the
point of cable entry as possible.
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.
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 pro-
vided 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.
Important information for the user

Unpacking and Installation
The carton and shipping materials used
to protect your new receiver during ship-
ment 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 .
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 sup-
plied with the unit as shown below.
Connect it to the AM and GND screw
terminals ¡.
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.
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.
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.
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.
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
dion the rear panel. The audio, video
and S-Video IN jacks on the VCR should be connected to the Video Out jacks
ehon 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 fgjacks 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 connec-
tions 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 installa-
tion, 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 obstruc-
tion 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 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 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 forthe remote control is about one year innormal oper­ation. If the amber Sending indi­cator does not flash when remotebuttons are pushed, that is an indicationthat the batteries need to be replaced.
To change the batteries:
1. Remove the back cover by sliding it in the direction of the arrows.
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.
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 pro-
grammed 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 batter-
ies are fully charged. The remote will
also operate at an angle of up to 30° to
either side of the unit.
Always point the remote transmitter at
the front of the unit when issuing com-
mands. If you find that remote com-
mands 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, and the nine source
input keys: TV, DVD, VID1, VID2,
VID3, CD, TAPE1, TAPE2 and AM/FM.
Programmable keys are divided into two groups. Some keys may be programmed with a separate function for each of the inputs. Thus, these keys may change their code when the input source is changed. (e.g. The Play key may trans­mit a different code when CD is selected as opposed to when VCR is selected.) The keys that may be programmed with multiple codes are the following:
All Numeric Keys (0 9)

Toprogram the remote, follow these steps. Note that it is not necessaryto program all keys, only those that arerequired to operate the subject device. Keys not programmed will retain the codes preprogrammed at the factory.
1. Slide Use/Learn a switch at the top left corner of the remote to the right so that it is next to Learn.
2. If one of the multifunction buttons is being programmed press the source button (e.g. CD, VID1) you wish to have this function associated with. If you
are programming a single function key,
proceed to the next step.
3. Press the button on the remote that is
to be programmed. Note that the
Learning ` LED will illuminate.
4. Place the remote head to head with the
remote control whose function is being
learned. The two remotes should be no
more than 8 inches apart.
5. Press and hold the button on the
remote corresponding to the function
to be memorized until the Learning
LED starts to blink. When the LED goes
out, release the button on the transmit-
ting remote. The function code has been
successfully captured by the remote.
NOTE: If both LEDs flash during a pro-
gramming operation, it indicates that
the remote’s memory is full or that the
remote codes from the transmitting
remote are not compatible with the unit’s
signal format.
6. Continue to program anyadditional
remote commands required using steps
2 through 5. When youhave finished
programming the remote, slide the
Use/Learn switch tothe left so that it
is in the Useposition.
Clearing the Remote Memory
In normal operation, codes for a new
device may be programmed “over” the
codes that have been previously pro-
grammed into the remote. It is also pos-
sible to clear the memory for individual
keys, or for the entire remote. When a
memory position is cleared, the remote
will return to the original factory preset
command.
To clear the memory for a specific indi­vidual key location, put the Use/Learn switch in the Learn position. Press the
Main Power Offc button and the
button to be cleared at the same time. Both the Sending and Learning indi­cators will light momentarily. When the lights go out, the memory has been cleared of the user programmed code and returned to the factory preset. Return the Use/Learn a switch to the Use position when you are finished.
To clear the remote’s entire memory and return all keys to their factory preset commands first put the Use/Learn a switch in the Learn position. Then press the Main Power Onbutton c and confirm that the Learning indicator
` has illuminated. While continuing
to press the Power Onbutton, press and hold the Power Offc button until the
Learn indicator goes off for about 3 sec-
onds. It will then blink twice. Then release the two buttons. This indicates that the memory has been cleared of any user programmed commands and that the original commands have been restored. Slide the Use/Learn switch
a back to the Use position to return
the remote to normal operation.

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 24off 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 with-
out 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 place-
ment is highly influenced by room size
and shape, and the type of subwoofer
used. Follow the instructions of the sub-
woofer’s manufacturer, or experiment
with the best location for a subwoofer in
your listening room.
A) Front Channel Speaker Installation with Direct View TV Sets or Rear Screen Projectors
B) The distance between the left and right speakers should be equal to the distance from the seating position to the viewing screen.You may also experiment with placing the left and right speakers slightly forward of the center speaker.

Once the speakers have been placed in the room and connected, the final step is to enter the configuration information and balance the speaker output levels. Before proceeding further this is a good time to review the installation section of the manual to make certain that all connections are properly made.
1. Plug the unit into an AC wall outlet and press the Powerbutton on the front panel 1. Note that the ring sur­rounding the front panel switch will turn red, then green, and the front panel display will illuminate.
2. Install the supplied AAA batteries in the remote as shown on page 15.
3. Turn on the TV connected to the receiver. Select the appropriate video input on the TV.
NOTE: Although the unit will switch S-Video signals, the on-screen menus control system is NOT visible on the S-Video output.
4. Press the Select button j on the remote to bring the MAIN MENU up on your video screen.
5. Press the ¤ button four times until the on-screen cursor >is pointing to
SET UP MENU (see figure #1).
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
CH. speaker by using the or buttons
i on the remote to select the type of
front channel speaker that will be used. Press the buttons so that LARGE or
SMALL is highlighted to match the
speaker type you will use as described in item #7 above. The LARGE setting sends a full-range output to the front left/right speakers, while the SMALL setting sends low-frequency sounds to the subwoofer output. When the selection has been made, press the ¤ button once so that the on-screen cursor >is pointing to the SURROUND CH. line of the display.

9. Enter the information for the
SURROUND CH. speaker by using the
or buttons i on the remote to
select the type of surround channel speaker that will be used. Press the buttons so that LARGE, SMALL or
NONE is highlighted to match the speak-
er type you will use as described in #7 above. The LARGE setting sends a full range output to the left/right surround speakers, while the SMALL setting sends low-frequency sounds to the subwoofer output or to the front speakers when no subwoofer is selected. If the surround speakers will not be used, the NONE setting will send the audio for the surround channels to the front left/right speakers. When the selection has been made, press the ¤ button once so that the on-screen cursor >is point­ing to GO TO SETUP MENU 2 . Press
Select j to move to the next menu.
10. At SETUP MENU 2 (see figure #3), you enter information that configures the AVR75 for the type of center channel speaker to be used, and whether or not a subwoofer is in use. While the on-screen cursor is pointing to CENTER CH. press the or buttons i on the remote to select the correct type of center channel speaker as described in #7. When
LARGE is highlighted a full-range sig-
nal will be sent to the center channel. When SMALL is highlighted the audio to the center channel will be cut at 100Hz and low-frequency information will be routed to the subwoofer output or to the front left/right speakers if no sub­woofer is selected. When the selection has been made, press the ¤ button once so that the on-screen cursor >is pointing to the SUBWOOFER line of the display.
to highlight ON or OFF. Select ON when an optional external subwoofer is con­nected to the Subwoofer Preamp
Output . If a subwoofer is not used,
highlight OFF. In this position all low­frequency sounds (below 100Hz) will be routed to the front left/right speakers. Note that the subwoofer cannot be set to
OFF when the front speakers are set to SMALL in SETUP MENU 1 . When the
selection has been made press the ¤ button once so that the on-screen cursor
is pointing to GO TO SETUP MENU
>
3. Press Select j to move to the next
menu.
12. At SETUP MENU 3 (see figure #4), various control functions will be set. The first item is the LFE LEVEL
CONTROL. “LFE” is the Low-Frequency
Effects channel that is used when Dolby Digital signals are present. The normal setting for LFE is 0dB, but the control may also be set to -10dB for reduced output when an LFE signal is present. The LFE may also be turned
OFF to reduce low-frequency repro-
duction. When the LFE level is set, or to bypass this setting, press the ¤ button i on the remote to move to the next setting.
NOTE: When the LFE is set to OFF the LFE output is cut, and not sent to any other speaker.
13. The next line is the NIGHT MODE setting. This feature reduces the input
level for Dolby Digital sources only by
1/3 to 1/4 at their loudest thresholds,
preventing unwanted bursts of loud sounds without restricting the dynamic range or volume of other sounds or at less than maximum levels. The feature may be turned OFF by pressing the
or buttons i on the remote until
OFF is highlighted. The Night mode
may also be turned on and off at any time by pressing the Night button e on the remote. When the Night mode is set, or to bypass this setting, press the ¤ button i to move to the next setting.
14. The SETUP LOCK prevents any of the major control settings from being changed once it is engaged. This feature is set at the factory to UNLOCK, so that all settings may be adjusted. If you wish to prevent settings from being easily or inadvertently being changed, use the
or buttons i on the remote until
LOCK is highlighted. Once the LOCK
setting is engaged and you exit SETUP
MENU 3, no changes may be made to
any of the Setup menus. To make changes to these menus you must return to SETUP MENU 3 and use the or buttons i on the remote until
UNLOCK is highlighted. When the LOCK setting is engaged, the word LOCK will appear at the top of the
menus to remind you that no changes may be made. When all adjustments have been made, press the ¤ button i twice and then press Select j to
RETURN TO THE MAIN MENU.
At this point you may wish to adjust the delay time settings, although it is

best to use the factory settings for initial listening sessions. See the Advanced Features section later in this manual for information on delay settings.
The remaining item to be adjusted before normal use of the AVR75 is adjustment of the output levels. Correct adjustment of these settings is critical to proper oper­ation of the receiver in all surround modes, and particularly when Dolby Digital sources are being played.
1. To set the output levels press the
Select button j to call up the main
menu (see figure #1)if it is not already on the screen, and then press the the ¤ button i until the on-screen cursor is pointing to TEST TONE. Press Select
j to move to the TEST TONE menu.
2. When you press Select you will immediately hear a test noise from the front left speaker. The on-screen display will change to a graphic representation of each of the speakers in your room, with one speaker position blinking (see figure #5). That speaker is the one whose level is being set.
NOTE: This procedure will onlyoperate if the AVR75 is in the PRO LOGIC, AC-
3,MOVIE or DOLBY 3 STEREO
modes. If the test tone cannot be selected, check to see which surround mode is indicated in the front panel display. If it is not one of the modes mentioned above, select one of the correct modes using the
Mode Selectors y, and then move
the cursor to TEST TONE to restart the procedure.
3. While seated in the primary listening position, you should hear a test noise signal from the left front speaker. You may leave the volume setting where it is, or raise it to an appropriate level using the Speaker or ¤ buttons n on the remote. For a more precise cali­bration, we recommend that you use a sound pressure level meter.
4. Press the or CH Select button
imon the remote. Note that the
sound should now come from the Center Channel speaker if one is installed, and the icon for that speaker will flash on the screen. Use the Speaker or ¤ buttons n on the remote to change the level of the test noise so that it appears to be equal in level to the Front Left speaker.
5. Press the or Ch Select button
imagain, and repeat the procedure
for the Front Right, Surround Right and
Surround Left channels. Each time, use the Speaker or ¤ buttons n on the remote to change the volume level so that all speakers match, and the button i to move to the next channel.
NOTE: This test also serves as an oppor­tunity to verify that all speakers are properly connected. If the sound from a speaker location does not match the location shown on the video and front panel displays, turn the AVR75 off and check the speaker wiring to make certain that the speaker is connected to the correct output terminals.
6. When all speakers appear to have an equal volume, press the button i on the remote and then Select j to complete the procedure.
NOTE: You may also check the output levels at any time by pressing the Test
Tone button l. When the on-screen
display is also activated by pressing OSD
k, you will see the speaker icons and
level information superimposed on your video screen. Follow the instructions in steps 1 through 6 above to calibrate the system, and press the Test T one button
l again to cancel the test.

Toturn the AVR75on for the firsttime, press the front panelPowerbutton 1.
When you press the Powerbutton 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 Powerswitch will illuminate in amber. The AVR75 may be turned on by pressing either the
Main Power On button c or any of
the Source buttons on the front panel
24578)!.
NOTE: When the AVR75 is in the Standby mode, and the amber LED around the
Powerswitch is illuminated, it is NOT
disconnected from the AC main power.
To turn the AVR75 totally off, press and release the Powerbutton 1 until the LED surrounding the switch goes out.
Source Selection
To select or change the input source, press one of the Source buttons on the front panel 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 VISUALin 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.
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 g9on 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.
Basic Operation
23
When manually tuning stations, observe the Signal Level indicator R and the Tuned indicators L. The more bars that are visible on the Signal
Level indicator, the stronger the signal
and the better the station will sound. A station is properly tuned when the
Tuned indicator is illuminated.
Tuner Mode
Pressing the Mode & or FM Mode r button on the front panel or remote selects how a station will be received. When the button is pressed so that the
Auto indicator M is lit, stations broad-
casting in stereo will be received in stereo. You may note stereo broadcasts by observing that the Stereo indicator K will illuminate. When the Mode button
&ris pressed until the Autolight M
goes out, all stations will be received in a monaural mode regardless of the method of transmission.
NOTE: When a station is broadcasting in stereo, but has a weak signal level, the reproduction may not be acceptable. In this case, select the Auto Off mode, as monaural reception is less susceptible to noise in weak reception areas.
Tuner Presets
There are thirty preset positions that may be used to store your favorite stations in any order. These may be used to memo­rize the station’s frequency, reception mode and the station’s name. Stations may be preset automatically or manually, and then recalled in a variety of ways.
Automatic Station Preset Selection
This process automatically scans the AM and FM bands and enters all stations with proper signal strength into the memory. To automatically preset the tuner’s memory, follow these steps:
1. Select the tuner as the unit’s input by pressing the AM/FM button 2d.
2. Using the Tune buttons Òs, select the first station you wish to preset at the low end of the AM or FM band.
3. Start the automatic tuning preset by simultaneously pressing Memo and
Tune on the front panel . The
station tuned in step #2 will be entered into the tuner’s memory as PRESET1. The Memo indicator N will flash. The display will show increasing frequencies to indicate that the auto scan is in progress.
4. Each time the tuner finds a station the scanning will pause and the station will be played for five seconds. During this time you have the following options:
a. To enter the station in the next open memory position, no action is needed. After five seconds the tuner will enter the station and the preset number will be visible at the far left side of the main information display.
b. The frequency band may be changed by pressing the AM/FM button 2h.
c. If the tuner is scanning FM stations, the Mode may be changed from Auto to mono by pressing the
Mode button &.
d. If you do not wish to enter the cur­rent station into the preset memory, press the Tune ⁄ button Òs on the front panel or remote.
5. After the desired action is completed, or five seconds elapse, the tuner scan will continue. The operation will stop auto­matically when all 30 preset positions are filled or when both frequency bands have
been completely tuned, whichever comes first. To stop the automatic preset process at any time press the Clear button ^ or any input selection button.
Manual Tuner Preset
Stations may be manually entered into the tuner’s memory in any order. Manual entry is performed from the remote control only.
1. Tune to the desired station as outlined in the Tuner Operation Section.
2. Press the Memo button %vand note that the Memo indicator N will flash.
3. While the indicator is flashing for the next 5 seconds, enter a number from 1 to 30 using the number buttons on the remote x. Any number may be used, but if another station has already been programmed into the location number selected, the previous setting will be lost.
a. To enter a single digit memory location, press 0 before the number, or enter the number and wait a few seconds.
b. If an invalid number (other than 1–30) is entered, the display will flash to alert you that the entry is invalid and it will return to the previous frequency display.
4. When the preset memory has been properly programmed the Memo indicator N will stop blinking.
Station Name Preset
In addition to identifying stations by their broadcast frequency, each preset station may be assigned a name using alphanumeric characters. This enables you to identify a station by its call letters, program format, or any other five character phrase.
Basic Operation
24
1. Tune to the desired preset station.
2. Press and hold the Memo button %
v for more than three seconds.
3. Note that a character on the left side of the main information display will start to blink.
4. Enter the first character of the name using either the front panel Tune or ¤ buttons Ò or the alphanumeric buttons x on the remote.
A. To use the front panel buttons simply press and hold Tune Ò button until the desired letter or number appears. Note that the upper case alphabet will appear, followed by the numbers 1 through 0, and then a Ðindicating a blank space. Tapping the button will advance the display one character at a time; holding it down will move the display quickly. If you pass by the desired character, use the Tune ¤ Ò to move the display in reverse.
After entering the first character, press
Memo % to move to the next position
and note that the next digit will blink. Use the same procedure outline above to enter a character.
When you have entered a digit or “blank” in all five spaces, press and hold the Memo button % for a second to confirm the entry
B. To use the remote for character entry, press the button corresponding to the desired letter or number. Press it once to enter the first printed letter, twice for the second, three times for the third and four times for the number. Press the “9” button once to enter a blank space. (For example, press the “ABC” button once to enter an “A,” three times for a “C” and four times to enter a “1”. )
Use the Memo button v to move to the next digit position. When all five spaces have been filled, press and hold the Memo button again for a second to confirm the entry.
Once a station name has been attached to a preset position, the station’s frequency will appear briefly when the unit is tuned to that station. After a few seconds the preset name will appear in the display.
Tuning Preset Stations
Stations preset into the tuner’s memory may be recalled in a number of ways.
1. To recall a station directly enter a number from 1 to 30 using the number buttons on the remote x.
a. To enter a single digit memory location, press 0 before the number, or enter the number and wait a few seconds.
b. If an invalid number (other than 1–30) is entered, that number will flash to alert you that the entry is invalid.
2. To scan through the list of preset stations, press the P-Setor
P-Set ¤ button on the front panel Ó
or the ‡·buttons u on the remote. Press once to move up or down through the memory presets one by one, or press and hold the button to quickly scan through the list of stations.
3. To automatically review each station in the memory, press the P-Scan button w. Note that the P-Scan indicator G will blink.
• The tuner will move up through the list of stations, pausing to play each for five seconds. Note that preset numbers where no station has been programmed will be skipped.
• When the desired station is reached press P-Scan w.
Clearing Preset Stations
Once stations are programmed into the preset memories, it is possible to remove them individually or as a group.
To remove a single station from the memory:
1. Recall the station by pressing the
buttons on the remote corresponding to the station’s memory location.
2. Press the Memo button % or v
and observe that the Memo indicator
O will blink.
3. While the indicator is blinking, press
the Clear button ^ within five seconds. The word CLEAR will show briefly to confirm that the memory position has been cleared.
To clear all memory locations for the
tuner, as well as all volume level and surround mode memories:
1. Press the front panel Memo % and

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 £∞ehis 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
Tape1 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 Monitormode.
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 Powerbuttons 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 thefront 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.
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 RFjack 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 back- up 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

ing, the AVR75 will automatically detect

if it is a multichannel Dolby Digital source or a conventional PCM signal, which is the standard output from CD players. An indicator will light in the Front Panel Information Display to confirm the digital signal is AC-3 A or PCM Q and if the source is RF,
Optical or Coax C.
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
Main Information Display J will
change to show the input source (RF, Optical or Coax) and then the surround mode will briefly be displayed (DOLBY AC-3). After these displays appear briefly, the display will show the selected analog source and the digital surround mode as follows:
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 6eon 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 Main
Information DisplayJ will show
both the last analog source and the type of digital input in use (e.g., CD/COAX).

The first time a PCM source is played the AVR75 will automatically select the Stereo mode, but you may then select any surround mode desired.

FEATURES
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 Low­Frequency Effects channel. Use this mode with DVD, LV or HDTV sources featuring Dolby Digital playback.
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.
Recording When Digital Sources Are In Use
Since the record outputs of the AVR75 are traditional two-channel stereo, the multichannel outputs of a Dolby Digital signal may not be recorded. When any
digital signal is being played, the accom­panying analog audio signal is sent to the Tape Outand VCR Out jacks £
∞eh. The video source being output
is the last selected video input shown in the Visual indicator P.

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.
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.
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.
This mode is designed for use with sports broadcasts, live concerts or other programs where the feeling of a wide surround effect is desired.
This mode turns off all surround processing and presents the pure left and right channel presentation of two channel stereo programs.

Memory Backup
This product is equipped with a memory backup system that preserves tuner pre­sets and system configuration informa­tion if the unit is accidentally unplugged or subject to a power outage. This mem­ory will last for approximately one week, after which time all information must be re-entered.
System Reset
In the rare case where the unit’s opera­tion or the displays seem abnormal, the cause may involve the erratic operation of the system’s memory ormicroprocessor.
To correct this problem, first unplugthe unit from the AC wall outletand wait at least three minutes. After the pause, reconnect the AC power cord andcheck the unit’s operation. If the system still malfunctions, a system reset may clear the problem.
To clear the entire system memory of the unit, press and hold the MEMO % and
CLEAR ^ buttons until CLEAR MEMO
appears in the front panel display. Release the buttons and note that the unit will turn off and then on.
Remember that once you have cleared the memory in this fashion it will be necessary to re-establish all system configuration information and tuner presets.
If the system is still operatingincorrectly, there may have been an electrostatic discharge or severe AC line interference that has corrupted the memory or microprocessor.
If a reset does not solve the problem, consult an authorized Harman Kardon service depot.
