Hooking Up and Setting Up the Speaker System

x Surround back speaker size

(SURR BACK)

• 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 surround back

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 a surround back speaker,

select “NO”.

• If you use the surround back speaker in the 2nd

room, select “2ND ROOM”. When the

surround back speaker is set to “2ND ROOM”,

the center speaker is also automatically set to

“2ND ROOM” (unless preciously set to “NO”)

(STR-DB1070 area code U, CA only).

Tip

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”

speakers.

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 36.

x Surround back speaker single or

double (SURR BACK L/R)

(STR-DB1070 only)

• When the center speaker is set to “NO” and you

use the center speaker as a surround back right

speaker and use the surround back speaker as a

surround back left speaker, select “YES”.

• If you use only a surround back speaker, select

“NO”.

x Sub woofer selection (SUB WOOFER)

• 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.

• In order to take full advantage of the Dolby

Digital bass redirection circuitry, we

recommend setting the sub woofer’s cut off

frequency as high as possible.

x Front speaker distance (FRONT)

Set the distance from your listening position to

the front speakers (A on page 19).

x Center speaker distance (CENTER)

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 19) to a distance

1.5 meters (5 feet) closet to your listening

position (B on page 19). When this range is

exceeded, the display blinks. If you make the

setting while the display blinks, you cannot

fully enjoy the surround effect.
