Re: Setting up subwoofer with X32
Yes the sub does not waste energy it does not reproduce, but you waste precious power by sending low end from channels that may have energy in the sub's range. For example vocal mics with a pass filter not engaged or set really low can have a lot of stage rumble and other noise that can really mud up and get in the way of the instruments you want in the sub. If you are having issues with not having enough output to adequately do a particular job one can use the power in the system more efficiently by only not reproducing any more of the range of frequencies than are necessary from each channel. Depending on what I have on stage I pass filter vocals at 200 hertz at times lower depending. I pass filter my toms in the drum kit at 160 hertz sometimes lower. Its like a puzzle. If you only have limited power in your system you need to keep the mix efficient to get what you need with out going beyond the limits. Even if you have a powered sub that has its on internal crossover, it my not be adjustable and may be too high and may not have the desired curve to be efficient in a particular set up so setting your own crossover point for it can be very helpful and save eq work later. A little pink noise though each part of the system separately while operating the cross over filter can help narrow down what each component does and adjust accordingly.
