A question for the wise - I can't see the answer in the manuals!
Various crossovers, including Peavey, Behringer and dbx have a switchable low cut. Is this low cut applied to the signal before routing to the subwoofer out, or is it used for the main left and right channels, or both? Some other products also have these low couts - Behringer Equalisers, for example. Which principle applies there? Regards, Ben Edited by salzburgsoundsystem - 22 November 2011 at 12:27pm |

Surely it makes no difference?
The crossover will only output the frequency-range affected by the low-cut to the sub out anyway. That's the whole point of a crossover! So it makes no difference if you cut them out "at the start" or on the sub output only.

like the 25hz low cut buttons on the behringer analogue ones? it's there as a safety really.. to cut the very low frequencies.. and it's on the inputs in that case.

Excellent! My new cabinets are safely within xmax down to 20 Hz, so a 25Hz low cut would do the trick.
Thanks! |
