Using Powered Subwoofers
To find the best position for your subwoofer, while playing
a movie or some music with good bass, experiment by
placing your subwoofer at various positions within the
room, and choose the one that provides the most satisfying
results.
You can connect the powered subwoofer with two
SUBWOOFER PRE OUT jacks respectively.
The same signal is output from each jack.
Tip
• If your subwoofer is unpowered and you’re using an external
amplifier, connect the subwoofer pre out jack to an input on the
amplifier.
