Multi-Channel Surround Setup

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).

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).)

Specifying the speaker types

p Front 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”).

p Center 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. *

• If you do not connect the center speaker, select “NO”. The sound of the center channel will be output from the front speakers.*

1 Press 1/u to turn on the receiver. 2 Press SET UP to display “SPEAKER SETUP”. 3 Press the cursor buttons ( or ) to select the

parameter you want to adjust.

4 Press the cursor buttons ( or ) to select setting

you desire. The setting is entered automatically.

5 Repeat steps 3 and 4 until you have set all of the

parameters that follow.

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”.*

*1~*3 correspond to the following Dolby Pro Logic modes

*1 NORMAL *2 PHANTOM *3 3 STEREO

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.

C C

p Rear speaker height (REAR HGT.)*

Initial setting : LOW This parameter lets you specify the height 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 “LOW” if the location of your rear speakers corresponds to section A.

• Select “HIGH” if the location of your rear speakers corresponds to section B.

This setting only effects the surround modes in the VIRTUAL 3D genre.

* These parameters are not available when “Rear speaker

size (REAR)“ is set to “NO”.

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.
