Phase Switch
The phase control on a REL has two posions, 0 and 180. One of these posions 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 posion results
in the loudest and fullest sub bass, is the correct posion.
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 pressurizaon in the
room and they are in phase. The opposite is if the speakers and REL are working against each other causing
cancelaon of low bass. We call this out of phase
