From the manual:

Quote:
Using a suitable cable, connect the AV receiver’s PRE
OUT: SW1, SW2 to an input on your powered subwoofer,
as shown. If your subwoofer is unpowered and
you’re using an external amplifier, connect the PRE
OUT: SW1, SW2 to an input on the amp.
You can connect the powered subwoofer with each jacks
respectively. Level and distance can be set individually
for each output. If you use one subwoofer, connect it to
PRE OUT: SW1.


So using SW1 is correct.

Quote:
1ch: Audio signal is outputted from SW1 jack only.
2ch: Audio signal is outputted from SW1 and SW2 jacks (default).
No: Select if no subwoofer is connected


Check the speaker level/sub settings and ensure it is set to 1ch or 2 ch and not NO, preferrably set to ch1 as you only have one sub
