    Stripped cords are touching each other
    due to excessive removal of insulation.
    Stripped cords are not fully attached and
    are touching the rear panel of the receiver.
    After connecting all the components,
    speakers, and AC power cord, output
    a test tone to check that all the
    speakers are connected correctly.
    For details on outputting a test tone,
    see page 18.
    If no sound is heard from a speaker while
    outputting a test tone or a test tone is output
    from a speaker other than the one whose name
    is currently displayed on the receiver, the
    speaker may be short-circuited. If this happens,
    check the speaker connection again.
    To avoid damaging your
    speakers
    Make sure that you turn down the volume
    before you turn off the receiver. When you turn
    on the receiver, the volume remains at the level
    you turn off the receiver.
    TipTo prevent speaker vibration or movement while
    listening, attach the supplied foot pads at the bottom
    of the speakers.
    Notes• Connect the long speaker connecting cords to the
    surround speaker terminals and the short speaker
    connecting cords to the front and center speaker
    terminals.
    • Twist the stripped ends of the speaker cords about
    10 mm (2/3 inch). Be sure to match the speaker
    cord to the appropriate terminal on the components:
    + to + and – to –. If the cords are reversed, the
    sound will be distorted and will lack bass.
    • If you use speakers with low maximum input rating,
    adjust the volume carefully to avoid excessive
    output on the speakers.
    To avoid short-circuiting the
    speakers
    Short-circuiting of the speakers may damage
    the receiver. To prevent this, make sure to take
    the following precautions when connecting the
    speakers.
    Make sure the stripped ends of each
    speaker cord does not touch another
    speaker terminal, the stripped end of
    another speaker cord, or the metal parts of
    the receiver.
    Examples of poor conditions of the
    speaker cord
    Stripped speaker cord is touching another
    speaker terminal.

    Performing initial setup
    operations
    Once you have hooked up the speakers and
    turned on the power, clear the receiver’s
    memory. Then specify the speaker parameters
    (size, position, etc.) and perform any other
    initial setup operations necessary for your
    system.
    TipTo check the audio output during settings (to set up
    while outputting the sound), check the connection
    (page 19).
    Clearing the receiver’s
    memory
    Before using your receiver for the first time, or
    when you want to clear the receiver’s memory,
    do the following.
    1Turn off the receiver.
    2Hold down ?/1 for 5 seconds.
    “INITIAL” appears in the display.
    The following are reset to their factory
    settings.
    • All settings in the SET UP, LEVEL and
    TONE menus.
    • The sound field memorized for each
    function and preset station.
    • All sound field parameters.
    • All preset stations.
    • All index names of input selectors and
    preset stations.
    • The master volume is set to “VOL
    MIN”.
    Performing initial setup
    operations
    Before using your receiver for the first time,
    adjust SET UP parameters so that the receiver
    correspond to your system. For the adjustable
    parameters, see the table on page 51. See pages
    14–18 for speaker settings and pages 34–35 for
    other settings.
    Multi channel surround
    setup
    For the best possible surround sound, all
    speakers should be the same distance from the
    listening position (A).
    However, the receiver lets you place the center
    speaker up to 1.5 meters (5 feet) closer (B)
    and the surround speakers up to 4.5 meters  (15
    feet) closer (C) to the listening position.
    The front speakers can be placed from 1.0 to
    7.0 meters (3 to 23 feet) from the listening
    position (A).
    You can place the surround speakers either
    behind you or to the side, depending on the
    shape of your room (etc.). However, we
    recommend that you place the surround
    speakers behind you.

    Normal Speaker and Micro
    Satellite Speaker
    For HT-DDW750, the speaker size and the sub
    woofer selection has been preset to “MICRO
    SP.” (Micro Satellite Speaker) according to the
    supplied speaker system.
    When you select “MICRO SP.”, the speaker
    size and sub woofer selection has been
    configurated as follows:
    Speaker Settings
    FRONT SMALL
    CENTER SMALL
    SURROUND SMALL
    SUB WOOFER YES
    You cannot change the configuration if you
    select “MICRO SP.”.If you change the speaker system, select
    “NORM. SP.”. You can adjust the speaker size
    and sub woofer selection when you select
    “NORM. SP.” (page 17).
    To select “NORM. SP.”, turn off the power,
    then turn on again while pressing MAIN
    MENU. (To reset to “MICRO SP.”, do the
    same procedure.)
    TipThe setting for Micro Satellite Speaker (MICRO SP.)
    has been programmed to optimize the sound balance.
    If you use Sony’s Micro Satellite Speakers, select
    “MICRO SP.”.
    CautionWhen you use Micro Satellite Speakers and the
    speaker size is set to “LARGE”, you may not obtain
    the correct soundstage. The speaker may also be
    damaged at high volume position.

    Set the distance from your listening position to
    the front speakers (A on page 14).
    xCenter speaker distance (C DIST.
    X.X m (XX ft.))
    Set the distance from your listening position to
    the center speaker. Center speaker distance
    should be set from a distance equal to the front
    speaker distance (A on page 14) to a distance
    1.5 meters (5 feet) closer to your listening
    position (B on page 14).
    xSurround speaker distance (SL SR
    DIST. X.X m (XX ft.))
    Set the distance from your listening position to
    the surround speakers. Surround speaker
    distance should be set from a distance equal to
    the front speaker distance (A on page 14) to a
    distance 4.5 meters (15 feet) closer to your
    listening position (C on page 14).
    TipThe receiver allows you to input the speaker position
    in terms of distance. However, it is not possible to set
    the center speaker further than the front speakers.
    Also, the center speaker cannot be set more than
    1.5 meters (5 feet) closer than the front speakers.
    Likewise, the surround speakers can not be set further
    away from the listening position than the front
    speakers. And they can be no more than 4.5 meters
    (15 feet) closer.
    This is because incorrect speaker placement is not
    conducive to enjoy surround sound.
    Please note that, setting the speaker distance closer
    than the actual location of the speakers will cause a
    delay in the output of the sound from that speaker. In
    other words, the speaker will sound like it is further
    away.For example, setting the center speaker distance
    1~2 m (3~6 feet) closer than the actual speaker
    position will create a fairly realistic sensation of being
    “inside” the screen. If you cannot obtain a satisfactory
    surround effect because the surround speakers are too
    close, setting the surround speaker distance closer
    (shorter) than the actual distance will create a larger
    sound stage.
    Adjusting these parameter while listening to the
    sound often results in much better surround sound.
    Give it a try!
    xSurround speaker placement (SL SR
    PL. XXXX)*
    This parameter lets you specify the height of
    your surround speakers for proper
    implementation of the Digital Cinema Sound
    surround modes. Refer to the illustration below.
    • Select “PL. LOW” if the location of your
    surround speakers corresponds to section A.
    • Select “PL. HIGH” if the location of your
    surround speakers corresponds to section B.
    * These parameters are not available when
    “Surround speaker size (SL SR)” is set to “NO”.

    continued
    TipThe surround speaker placement parameter is
    designed specifically for implementation of the
    Digital Cinema Sound modes with virtual elements.
    With the Digital Cinema Sound modes, speaker
    placement is not as critical as other modes. All modes
    with virtual elements were designed under the
    premise that the surround speaker would be located
    behind the listening position, but presentation remains
    fairly consistent even with the surround speakers
    positioned at a rather wide angle. However, if the
    speakers are pointing towards the listener from the
    immediate left and right of the listening position, the
    sound fields with virtual elements will not be as
    effective.
    Nevertheless, each listening environment has many
    variables, like wall reflections.
    Therefore, we recommend that you playback multi
    channel surround encoded software and listen to the
    effect each setting has on your listening environment.
    Choose the setting that provides a good sense of
    spaciousness and that best succeeds in forming a
    cohesive space between the surround sound from the
    surround speakers and the sound of the front
    speakers. If you are not sure which sounds best, select
    “PL. LOW” and then use the speaker distance
    parameter and speaker level adjustments to obtain
    proper balance.
    Only when you use the speaker system
    other than the supplied one, be sure to
    set the following parameters.
    For details on “NORM. SP.” (Normal Speaker), see
    page 15.
    xSub woofer selection (SW S.W. XXX)
    • If you connect a sub woofer, select “YES”.
    • If you do not connect a sub woofer, select
    “NO”. This activates the bass redirection
    circuitry and outputs the LFE signals from other
    speakers.xFront speaker size (
    L R XXXXX)
    • If you connect large speakers that will
    effectively reproduce bass frequencies, select
    “LARGE”. Normally, select “LARGE”.
    • If the sound is distorted, or you feel a lack of
    surround effects when using multi channel
    surround sound, select “SMALL” to activate
    the bass redirection circuitry and output the
    front channel bass frequencies from the sub
    woofer.
    • When the front speakers are set to “SMALL”,
    the center and surround speakers are also
    automatically set to “SMALL” (unless
    previously set to “NO”).
    • When the sub woofer is set to “NO”, the front
    speakers are automatically set to “LARGE” and
    you cannot change this setting.
    xCenter speaker size (
    C XXXXX)
    • If you connect a large speaker that will
    effectively reproduce bass frequencies, select
    “LARGE”. Normally, select “LARGE”.
    However, if the front speakers are set to
    “SMALL”, you cannot set the center speaker to
    “LARGE”.
    • If the sound is distorted, or you feel a lack of
    surround effects when using multi channel
    surround sound, select “SMALL” to activate
    the bass redirection circuitry and output the
    center channel bass frequencies from the front
    speakers (if set to “LARGE”) or sub woofer.*

    surround sound, select “SMALL” to activate
    the bass redirection circuitry and output the
    surround channel bass frequencies from the sub

    modes

    *2 PHANTOM
    *3 3 STEREO
    TipInternally, the LARGE and SMALL settings for each
    speaker determine whether the internal sound
    processor will cut the bass signal from that channel.
    When the bass is cut from a channel, the bass
    redirection circuitry sends the corresponding bass
    frequencies to the sub woofer or other “LARGE”
    speakers.
    However, since bass sounds have a certain amount of
    directionality, it is best not to cut them, if possible.
    Therefore, even when using small speakers, you can
    set them to “LARGE” if you want to output the bass
    frequencies from that speaker. On the other hand, if
    you are using a large speaker, but prefer not to have
    bass frequencies output from that speaker, set it to
    “SMALL”.
    If the overall sound level is lower than you prefer, set
    all speakers to “LARGE”. If there is not enough bass,
    you can use the BASS parameter in the TONE menu
    to boost the bass levels. To adjust the bass, see page
    27.
    Adjusting the speaker level
    Use the remote while seated in your listening
    position to adjust the level of each speaker.
    NoteThe receiver incorporates a new test tone with a
    frequency centered at 800 Hz for easier speaker level
    adjustment.
    1Press ?/1 on the remote to turn on the
    receiver.
    2Press TEST TONE on the remote.
    “T. TONE” appears in the display and you
    will hear the test tone from each speaker in
    sequence.

    3Adjust the speaker level and balance
    using the LEVEL menu so that the level
    of the test tone sounds the same from
    each speaker.
    For details on the LEVEL menu, see page
    26.
    While adjusting, the test tone is output from
    the speaker whose adjustment is performed.
    4Press TEST TONE again to turn off the
    test tone.
    TipYou can adjust the level of all speakers at the same
    time. Press MASTER VOL +/– on the remote or turn
    MASTER VOLUME on the receiver.
    Notes• The adjusted value are shown in the display during
    adjustment.
    • Although these adjustments can also be made via
    the front panel using the LEVEL menu (when the
    test tone is output, the receiver switches to the
    LEVEL menu automatically), we recommend you
    follow the procedure described above and adjust the
    speaker levels from your listening position using the
    remote.
