NOTES:
• If you have selected “NO” for the surround back speaker (see page
24), you cannot select this setting. 6.1-channel and 5.1-channel
software is played back in the same way as “OFF” is selected for
above setting.
• When the sound is not output from the surround back speaker even
though playing back Dolby Digital EX software (bearing the mark
) setting “EX/ES” to “AUTO,” select “ON” instead of “AUTO.”
Setting the speaker distance
—FRNT D (front speaker distance),
CNTR D (center speaker distance),
SURR D (surround speaker distance),
BACK D (surround back speaker distance)
The distance from your listening point to the speakers is
another important element to obtain the best possible sound
from the Surround and DSP modes. You need to set the
distance from your listening point to the speakers.
By referring to the speaker distance setting, this system
automatically sets the delay time of the sound through each
speaker so that sounds through all the speakers can reach
you at the same time.
Set the distance from the listening point to each speaker
with the range of 0.3 m to 9.0 m (in 0.3 m intervals).
NOTE:
If you have selected “NO” for “BACK SP” (see page 24), you cannot
set the speaker distance for the surround back speaker.
Setting the crossover
frequency
—CROSS
Small speakers cannot reproduce the bass sounds efficiently.
If you use a small speaker in any position, this system
automatically reallocates the bass sound elements assigned
to the small speaker to the large speakers.
To use this function properly, set the crossover frequency
level according to the size of the small speaker connected.
• If you have selected “LARGE” for all speakers, this function
does not take effect and you cannot change the frequency.

Setting the phase of subwoofer
—PHASE
Subwoofer phase is closely related with the distance from the
listening position to the front speakers and subwoofer. You
can change the phase to obtain better bass sound.
Select one of the following settings:
NORMAL :Normally select this.
REVERS :Select when you feel the bass sound is better
with this mode rather than with “NORMAL.”
Setting the video output for DVD
playback
—M.OUT (monitor out)
After connecting your TV (see page 7), select the video
output jack type you watch the DVD playback.
Setting this properly, you can use AV COMPU LINK remote
control system.—The TV automatically changes the video
input mode to the appropriate position (see “AV COMPU
LINK remote control system” on pages 60 and 61).
