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.

Setting the Test Tone
• Use this setting to adjust to that the playback level between the different channel is equal.
• From the listening position, listen to the test tones produced from the speakers to adjust the level.
• The level can also be adjusted directly from the remote control unit. (For details, see page 23.)

a. If the "Auto" mode is selected:
Test tones are automatically emitted from the different speakers.
The test tones are emitted from the different speakers in the following order, at
4-second intervals the first time and second time around, 2-second intervals the
third time around and on:

When the surround back speaker setting is set to "1sp" for "Speaker
Configuration", this is set to "SB".
Use the CURSOR left and right buttons to adjust all the speakers to the same
volume.
The volume can be adjusted between –12 dB and
+12 dB in units of 1 dB.
(Remote control unit)
b. When the "Manual" mode is selected
Use the CURSOR up and down to select the
speaker for which you want to output test tones,
then use the CURSOR left and right to adjust so
that the volume of the test tones from the various
(Remote control unit)
speakers is the same.
