pulled this from another forum...
what are your thoughts?
"thought of this last night... looking to start a decent discussion... skip to the bottom if you don't wanna read all this...
1. Cones and hornes can only vibrate at a certain frequency before destorting. Regardless of what they are playing, depending on the quality of horn (in this case lets use a standard JBL horn/woofer 3-way,...) if you send enough information through, and if that information is rather dynamic (as is most dnb) then your boxes are more prone to distortion. Now distortion itself based on wattage. (db, Dbspl, whatever it comes down to watts). Read on before you judge...
2. the human voice has a dynamic range of no less than 80hz and no more than 1.2Khz. Your typical response range of a JBL mid-range 3 way box is probably around 25hz to 15-19Khz. Drum and bass exercises around 60-6000hz. (FYI human hearing is sensitive to 20hz to 20khz...)
When one takes into consideration of a voice, in this case the voice of an MC, which is typically alto, which = 130-700hz, and distortion from the speakers due to deconstructive intereference (and remember this distortion is due to driving the sound so much that the CONSTRUCTIVE interference creates the deconstructive intereference between the separate signals, which is WAY common in the dnb/jungle world) one can come to a conclusion...
"all I hear is Blah bibbidy blee blah bippity blah"
here is my idea = increase clarity of an mc's voice by... giving them a separate system to work on. Keep their shit OFF of the dj mixer why???
because in the end all of the signals coming through that mixer are bussed to the main/rec/booth outs. That is your first point of doubling frequencies. If the voice of an MC operates within the range of most dnb, then any frequency from the mc's voice that matches the frequencey of anything goin on in the music will double, resulting in 6db of overall volume increase. Factor in Q, and you have an exponentital volume increase in the frequencies surrounding the matching frequencies as well...
Now this normally would not be a problem if those signals were not coming out of the same system. Once you have horns that are pushing the same signal, you are going to have ANOTHER 6dB increase. thats a 12DB increase just after physics are applied!!! Now factor in VCA control at the mixer and wattage control at the amp and you are looking at major distortion possibility!!!
Also, getting back to what I said before regarding how much information is put into the speakers... reduce your load = better sound quality.
basic message for those that didn't read? Put MC's on a separate system, their own amps, mixer and speakers. I think this would be a good way to really get the MC's and the music separated in an appropriate way!
and ALL of this is to go without mentioning the mic choice of the MC. A Nuemann is going to have a much larger potential to represent a larger frequency range than a SM58 will...
what does everyone think?
