11. PHASE 0° / 180° switch
This switch reverses the polarity of the subwoofer. Depending on the placement of the subwoofer rela ve to the
full-range sat speakers, you can get a be er low-frequency response in the room if you reverse the polarity of the
subwoofer’s signal. Listen in diff erent posi ons of the venue in order to fi nd which is the best sounding se ng.
NOTE: ALL SUBWOOFER SPEAKERS MUST BE HAVE THE SAME POLARITY, if you note a lack in lowest frequency range
using more than one subwoofer, probably you have a subwoofer out-of-phase respect to the other. Be always sure all
these switches are in same posi on.
