DL1608 with QSC K12 and KSUB

(1/13) > >>

Harpman:
I know a lot of you have this configuration.  I was using my Behringer B212D's prior to the K12's.  I would run the B212D's thru the mains and the KSUB thru AUX6.  There is one reason I do that.  No matter what type of crossover you have, running the mains thru the KSUB and to the K12 or B212 as tops, you still end up with some frequencies that don't need to be in the sub at all.  If I run the sub thru AUX6, I have full control over what instruments I want in the sub at all. I'm open for ideas if anyone can convince me otherwise.

No arguments here. You are doing exactly what you should be doing.

There are lots of reasons aux 6 works better. Sonically it sounds better but there are other reasons too.  What if you need to boost the bass some? With the aux 6 method you just raise the fader. With the through setup you need to turn up the volume on the speaker itself. I would rather us the board to do this then having to go over to my speakers every time. I use 2 subs myself and if I didn't use the aux 6 method then I would have to go to 2 subs and raise them both up. Separate sides of the stage. Fighting to get around equipment. I used to do it that way. With the aux 6 setup I just turn up the volume with my aux 6 fader. Easy breezy. Imagine your just running sound. And you are out front. With the through method you have to go back to the stage to adjust the subs to change the bass. Sometimes people say things are too loud and usually that's not coming from the subs. It's the highs that tear through people. With the aux 6 method you can also turn down the tops and leave the bass alone. And vice versa.

Its very nice to have control over what goes into the subs. The subs will be more efficient regardless of their built in crossover. A lot of people like to remove vocals from subs. I like to add a little in for some warmth. With the through method you have to use the eqs to do this. With aux 6 method you can just bring a little vocals back into the subs. I leave the eqs to polish the final sound, not to control my speakers.

You still need a crossover for the tops somewhere. The K12's have an internal one that can be switched on - the B212D's don't :( so need an external one.

Jerrylee:
Rr the b212s have a high and low eq that works well as a crossover. Just turn down the low. Or of course just use the 31 bad eq as a pseudo crossover. So you don't really need one. And you can only use the aux 6 method if you want to use the 31 band eq crossover option.

Sorry to say this but the b212d's are definitely a high end speaker. The places where they would be used as mains probably wouldn't care about if there are crossovers or not. Gio I'm sure you're glad you switched to the k12s. I have the b210d's and they make great monitors. Especially for the price. I also have k10s and k12s for monitors and they are night and day. I have had to use a b210d with a k12 as mains once at a gig because one of my k12s went out. It worked ok but was a huge tonal difference.

You don't need that if you are using subs and tops that have crossovers built-in like the QSC "K" series.
