This screen is not displayed when not using a subwoofer.
• Set the crossover frequency and subwoofer mode according to the speaker system being used.
• When using in combination with the SYS-550SD, we recommend turning the DSW-3L’s LF DIRECT switch on
and setting the AVR-550SD’s crossover frequency to 150 Hz. (See page 37.)

• To select the parameter
• Parameters
Large…… Select this when using speakers that can fully reproduce low sounds of below 80 Hz.
Small…… Select this when using speakers that cannot reproduce low sounds of below 80 Hz with sufficient
volume. When this setting is selected, low frequencies of below 80 Hz are assigned to the
subwoofer. (Example: SC-A3L, SC-C3L)
None…… Select this when no speakers are installed.
Yes/No…. Select “Yes” when a subwoofer is installed, “No” when it’s not installed.
• About the surround back speaker
When “S.Back. Sp.” is selected, the speaker systems change as described below.
When “NONE” is selected ..................................................................5.1ch speaker system
When “Large” or “Small” is selected and “1Speaker” is selected ....6.1ch speaker system
The surround back audio signals are output from both the speaker terminals and the PRE OUT connector’s
left channel. Connect one of these. A separate, commercially available pre-main (power) amplifier is
needed to connect the PRE OUT connector.
When “2 speaker” is selected ............................................................7.1ch speaker system
The surround back audio signals are only output from the PRE OUT connector. Connect a commercially
available pre-main (power) amplifier to output the audio signals. No sound is output from the “Surr. Back”
speaker terminals.
NOTE:
Select “Large” or “Small” not according to the physical size of the speaker, but according to the bass
reproduction capacity at 80 Hz. If you cannot determine the best setting, try comparing the sound when set to
“Small” and when set to “Large”, at a level that will not damage the speakers.
Caution:
In case the subwoofer is not used, be sure to set “Subwoofer = No”, or the bass sound of front channel is
divided to subwoofer channel and not reproduced in some mode.
If the subwoofer has sufficient low frequency playback capacity, good sound can be achieved even when
“Small” is set for the front, center and surround speakers.
For the majority of speaker system configurations, using the Small setting for all five main speakers and
Subwooofer On with a connected subwoofer will yield the best results.
