Components the Up Hooking
Other Hookups
S-LINK CONTROL A1 hookup
•If you have a S-LINK CONTROL A1-compatible Sony CD player, tape deck, or MD deck
Use a CONTROL A1 cord (not supplied) to connect the S-LINK CTRL A1 jack on the CD player, tape deck, or MD deck to the S-LINK CTRL A1 jack on the receiver. Refer to the separate manual “CONTROL-A1 Control System” and the operating instructions supplied with your CD player, tape deck, or MD deck for details.
Note
If you make CONTROL A1 connections from the receiver to an MD deck that is also connected to a computer, do not operate the receiver while using the “Sony MD Editor” software. This may cause a malfunction.
•If you have a Sony CD changer with a COMMAND MODE selector
If your CD changer’s COMMAND MODE selector can be set to CD 1, CD 2, or CD 3, be sure to set the command mode to “CD 1” and connect the changer to the CD jacks on the receiver.
If, however, you have a Sony CD changer with VIDEO OUT jacks, set the command mode to “CD 2” and connect the changer to the VIDEO 2 jacks on the receiver.
Connecting the AC power cord
Before connecting the AC power cord of this receiver to a wall outlet:
•Connect the speaker system to the receiver (see page 12).
•Turn the MASTER VOLUME control to the leftmost position (0).
Connect the AC power cord(s) of your audio/video components to a wall outlet.
If you connect other audio/video components to the AC OUTLET(s) on the receiver, the receiver will supply power to the connected component(s), allowing you to turn the whole system on or off when you turn the receiver on/off.
Caution
Make sure that the total power consumption of the component(s) connected to the receiver’s AC OUTLET(s) does not exceed the wattage stated on the rear panel. Do not connect high-wattage electrical home appliances such as electric irons, fans, or TVs to this outlet.
Note
If the AC power cord is disconnected for about one week, the receiver’s entire memory will be cleaned and the demonstration will start.

Notes on speaker system hookup
•Twist the stripped ends of the speaker cords about
2/3 inch (15 mm). 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 front speakers with low maximum input rating, adjust the volume carefully to avoid excessive output on the speakers.
•The WIRELESS REAR SPEAKER jack is for use with Sony wireless rear speaker systems only, do not connect any other speaker systems or components to this jack.
12
Speaker impedance
To enjoy multi channel surround, connect front, center, and rear speakers with a nominal impedance of 8 ohms or higher, and set the speaker IMPEDANCE SELECTOR to “8Ω.” Check the instruction manual supplied with your speakers if you’re not sure of their impedance. (This information is usually printed on a label on the back of the speaker.)
You may connect a pair of speakers with a nominal impedance between 4 and 8 ohms to the FRONT
SPEAKERS terminals, if you set the IMPEDANCE SELECTOR to “4Ω” but you will not be able to enjoy
multi-channel surround sound.
Note
Be sure to connect front speakers with a nominal impedance of 8 ohms or higher if you want to select both sets (A+B) of front speakers (see page 21).
Multi-Channel Surround
Setup
For the best possible surround sound all speakers should be the same distance from the listening position (A). (However, this unit lets you to place the center speaker up to 5 feet (1.5 meters) closer (B) and the rear speakers up to 15 feet (4.5 meters) closer (C) to the listening position. The front speakers can be placed from 3 to 40 feet (1.0 to 12.0 meters) from the listening position (A).)

5Repeat steps 3 and 4 until you have set all of the parameters that follow.
pFront speaker size (FRONT)
Initial setting : LARGE
• 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 speaker is set to “SMALL”, the center and rear speakers are also automatically set to “SMALL” (unless previously set to “NO”).
pCenter speaker size (CENTER)
Initial setting : LARGE
•If you a connect 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 the center speaker, select “NO”. The sound of the center channel will be output from the front speakers.*2
p Rear speaker size (REAR)
Initial setting : LARGE
•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 rear 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 rear channel bass frequencies from the sub woofer or other “LARGE” speakers.
•If you do not connect rear speakers, select “NO”.*3

z About speaker sizes (LARGE and SMALL)
Internally, the LARGE and SMALL settings for each speaker determine whether or not 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” speaker. However, since bass sounds have a certain amount of directionality it 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 equalizer to boost the bass levels. To adjust the equalizer, see page 31.
p Rear speaker position (REAR PL.)*
Initial setting : BEHIND
This parameter lets you specify the location of your rear speakers for proper implementation of the Digital Cinema Sound surround modes in the VIRTUAL 3D genre. Refer to the illustration below.
•Select “SIDE” if the location of your rear speakers corresponds to section A.
•Select “MIDDLE” if the location of your rear speakers corresponds to section B.
•Select “BEHIND” if the location of your rear speakers corresponds to section C.
This setting only effects the surround modes in the VIRTUAL 3D genre.

z About the rear speaker position (SIDE, MIDDLE, and BEHIND)
This setting is designed specifically for implementation of the Digital Cinema Sound modes in the VIRTUAL 3D genre.
With the Digital Cinema Sound modes, speaker position is not as critical as other modes. All of the modes in the VIRTUAL 3D genre were designed under the premise that the rear speaker would be located behind the listening position, but presentation remains fairly consistent even with the rear speakers positioned at a rather wide angle. However, if the speakers are pointing toward the listener from the immediate left and right of the listening position, the VIRTUAL 3D modes will not be effective unless the rear speaker position parameter is set to “SIDE”. Nevertheless, each listening environment has many variables, like wall reflections, and you may obtain better results using “BEHIND” or “MIDDLE” if your speakers are located high above the listening position, even if they are to the immediate left and right.
Therefore, although it may result in a setting contrary to the “Rear speaker position” explanation, 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 rear speakers and the sound of the front speakers. If you are not sure which sounds best, select “BEHIND” and then use the speaker distance parameter and speaker level adjustments to obtain proper balance.
