ENGLISH
• Input the distance between the listening position and the different speakers to set the delay time for the surround
mode.
Preparations:
Measure the distances between the listening position and the speakers
(L1 to L5) on the diagram at the right).
L1: Distance between center speaker and listening position
L2: Distance between front speakers and listening position
L3: Distance between surround speakers and listening position
L4: Distance between surround back speaker and listening position
L5: Distance between subwoofer and listening position
CAUTION:
Please note that the difference for every speaker should be 4.5 m or less.
NOTE:
• No setting when “None” has been selected for the Speaker Configuration setting.
Setting the delay time
1
Select the speaker to be set.
NOTES:
— Assignment of low frequency signal range —
• The signals produced from the subwoofer channel are LFE signals (during playback of Dolby Digital or DTS
signals) and the low frequency signal range of channels set to “SMALL” in the setup. The low frequency
signal range of channels set to “LARGE” are produced from those channels.
— Crossover Frequency —
• When “Subwoofer” is set to “Yes” at the “Speaker Configuration Setting”, set the frequency (Hz) below
which the bass sound of the various speakers is to be output from the subwoofer (the crossover
frequency).
• For speakers set to “Small”, sound with a frequency below the crossover frequency is cut, and the cut bass
sound is output from the subwoofer instead.
NOTE : For ordinary speaker systems, we recommend setting the crossover frequency to 80 Hz. When
using small speakers, however, setting the crossover frequency to a high frequency may improve
frequency response for frequencies near the crossover frequency.
— Subwoofer mode —
• The subwoofer mode setting is only valid when “Large” is set for the front speakers and “YES” is set for
the subwoofer in the “Speaker Configuration” settings (see page 12).
• When the “LFE+MAIN” playback mode is selected, the low frequency signal range of channels set to
“Large” are produced simultaneously from those channels and the subwoofer channel.
In this playback mode, the low frequency range expand more uniformly through the room, but depending
on the size and shape of the room, interference may result in a decrease of the actual volume of the low
frequency range.
• Selection of the “LFE ” play mode will play the low frequency signal range of the channel selected with
“Large” from that channel only. Therefore, the low frequency signal range that are played from the
subwoofer channel are only the low frequency signal range of LFE (only during Dolby Digital or DTS signal
playback) and the channel specified as “Small” in the setup menu.
• Select the play mode that provides bass reproduction with quantity.
• When the subwoofer is set to “Yes”, bass sound is output from the subwoofer regardless of the subwoofer
mode setting in surround modes other than Dolby/DTS.
• In surround modes other than Dolby Digital and DTS, if the subwoofer is set to “YES”, the low frequency
portion is always output to the subwoofer channel. For details, refer to “Surround Modes and Parameters”
on page 30.

Set the distance between the speaker and listening position.
The distance changes in units of 0.1 meters each time the button is pressed.
Select the value closest to the measured distance.
