Step 5: Setting the Phase Switch.
This will ensure that your ebode SubWoofer sounds it's very
best in your favourite listening position. It is easiest to do with
two people: One at the listening position and the other at the
SubWoofer.
A) Your ebode Wireless SubWoofer is set up and ready to play.
Play a favourite piece of music, ideally one with a lot of bass to
ensure it's functioning properly.
B) With one person at the listening position or some convenient
position not too close to the subwoofer (2 to 3 meter back is
fine) and the other person operating the phase, switch on the
back of the SubWoofer.
