Enter the setting.
The System Setup Menu reappears.
NOTES:
— Assignment of low frequency signal range —
• The only 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 menu. 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 10).
• 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 38.
Setting the delay time
• Input the distance between the listening position and the different speakers to set the delay time for the
surround mode.
• The delay time can be set separately for surround speakers A and B.
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 speakers and listening position
L5: Distance between subwoofer and listening position

NOTES:
• If the distance unit is changed after the delay time is set, the settings are reset to the factory default values
(see pages 9, 10).
Switch to the Delay Time screen.
Select the desired unit, meters or feet.
Select (darken) the desired units, "Meters" or "Feet".
Select the speaker to be set.
Set the distance between
the center speaker and
listening position.
The distance changes in
units of 0.1 meters (1 foot)
each time the button is
pressed. Select the value
closest to the measured
Example: When the distance is set to
distance.
3.6 m for the center speaker
If "Yes" is selected for "Default", the settings are
automatically reset to the default values.
Please note that the difference of distance for every speaker
should be 6.0 m (20 ft) or less. If you set an invalid distance,
a CAUTION notice, such as screen right will appear. In this
case, please relocate the blinking speaker(s) so that its
distance is no larger than the value shown in highlighted line.
Enter the setting.
The System Setup Menu reappears.
The AVR-3803 automatically sets the optimum surround delay time for the listening room.
