Phase Switch
The phase control on a REL has two posions, 0 and 180. One of these posions will set the REL in phase
with the speakers, and one will set it out of phase. The labels 0 and 180 are just labels and tell us nothing
about the rest of the system, only if the REL is working with the speakers or not. Whichever posion results
in the loudest and fullest sub bass, is the correct posion.
We want the REL to work in harmony with the speakers, reinforcing bass, not cancelling it. In other words,
we want the drivers in the speakers and the REL to move forward at the same me and move backward at
the same me. When this happens, it results in an increase in sub bass volume and the pressurizaon in the
room and they are in phase. The opposite is if the speakers and REL are working against each other causing
cancelaon of low bass. We call this out of phase
