Fine-tuning
1. Connect the mains supply and switch on the Radius 360/720. Play the music/
movie at an average listening level; the Subwoofer should switch on automatically
(blue LED on front will illuminate)
2.The volume control can now be adjusted to a desirable level.
3. The frequency control can now be set to give a seamless sound balance. The
setting will depend on the low frequency response of the main/satellite speakers.

very important to try a variety of music/movies with which you are familiar in order
to obtain the optimum overall settings.
