Hooking Up and Setting Up the Speaker System 13GB HT-DDW750 4-244-183-11(1) GB 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. 01GB04HUPCA.p6511/29/02, 2:15 PM 13

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. Specifying the speaker parameters 1Press MAIN MENU repeatedly to select “SET UP”. 2Press MENU or MENU to select the parameter you want to adjust. 3Press MENU + or MENU – to select the setting you want.

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”. 01GB04HUPCA.p6511/29/02, 2:16 PM 16
Hooking Up and Setting Up the Speaker System 17GB HT-DDW750 4-244-183-11(1) GB 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.* 1 • If you do not connect a center speaker, select “NO”. The sound of the center channel will be output from the front speakers.* 2 01GB04HUPCA.p6511/29/02, 2:16 PM 17
18GB HT-DDW750 4-244-183-11(1) GB Multi channel surround setup (continued) xSurround speaker size (SL SR XXXXX) • If you connect large speakers that will effectively reproduce bass frequencies, select “LARGE”. Normally, select “LARGE”. However, if the front speakers are set to “SMALL”, you cannot set the surround speakers 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 surround channel bass frequencies from the sub woofer or other “LARGE” speakers. • If you do not connect surround speakers, select “NO”.* 3 Tip*1–*3 correspond to the following Dolby Pro Logic modes *1 NORMAL *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. Front (left) t Center t Front (right) t Surround (right) t Surround (left) t Sub woofer 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. 01GB04HUPCA.p6511/29/02, 2:16 PM 18
