Phase: Controls the polarity of the frequencies outputted. If you have 2 subwoofers in your room/theater that are facing each other, put one at 0 degrees and the other at 180 degrees so that they don't cancel each other's frequencies out.
What does a subwoofer phase switch do?
The phase control in a powered subwoofer allows the user to add electrical delay to the incoming signal. The phase control operates over a range of 0 to 180 degrees. Adding delay to the subwoofer signal can sometimes help the subwoofer to integrate better with the loudspeakers in the room.
What phase should my subwoofer be set at?
Typically, though, phase is left at 0° for most applications. While seated in your listening sweet spot, play music with bass content that is familiar to you and then have someone switch the 0/180 phase switch on the sub to 180-degrees. This will let you determine if the bass sounds louder in your seating position.
Does phase matter on subwoofer?
The subwoofer phase (or in your case polarity switch) is for use with mulitiple subwoofers but if 180° sounds best to you then leave it at 180°. The test tone is supposed to be at the frequency of the crossover point not 40HZ.
How do you use the phase on a subwoofer?
Your speaker's bass driver should be pulsing outward on a bass transient, like a kick drum's “thump”. For your system to be properly in phase, or aligned to this action, your subwoofer needs to have its driver pulse outward on the same kick drum thump.
How do you use phase control on a subwoofer?
Align the phase of the main speakers and subwoofer Return to the center seating position in front of the main speaker and subwoofer. With your head placed equidistant from each, slowly rotate the subwoofer's phase control knob clockwise and notice the bass drop off significantly, then begin to rise.
How do I know if my subwoofers are out of phase?
If the sub and main speakers were in phase, he'd hear a single thump when he connected the battery to the wires leading to the sub's terminals. If they were out of phase, he'd hear a double thump. That's with passive subwoofers, though.
What is phase in subwoofer normal or reverse?
The phase button should be in Normal if you are running just one subwoofer. But if you are running two subwoofers then do one in normal and the second one in reverse.
What happens when speakers are out of phase?
Registered. Wiring speakers "out of phase" will "destroy" imaging — sounds that should "center" between the two main speakers might sound very diffuse, instead — and can cause the apparant sound level to be diminished (weakened bass, for example).
