Have none of you guys put the comp between the low-out and amp (leave the hi-out un-affected)? Why squash the hi-end when it's really only the lows that need to be punch-ed up?

When someone screams/vocals into a mike it can fry your tweeters!
 
I run my Compressors/Limiters out the back of my mixer and back into the mixer on each mic channel. They scream more than I like, also it helps with the singer that can't hang onto the mic.

When you say bi-amping. Your meaning one amp for the subs and one amp for the mains. Correct.

That's the way I have it now.

I had my crossover at around 100hz. I will move it up to the 110hz level and try it out.

On a side note, is it better to put the subs together in the middle etc, and the mains on the sides. My first try was with the mains on top of the subs about 60ft apart. I have heard it's a either or type thing. Either right next to each other or spread way apart.

Yup. Actually you may accomplish this with a single two-channel amp if you're running mono. Patch the mains to channel one, the subs to channel two. The subs don't need a stereo feed anyway.

If and when possible, place the sub cabs together, side by side. If they're spread apart by, say 10 feet or so they can cancel each other. If you have 50 or 60 feet available to you, you may separate 'em that way.

I assume you split the output of the amp with a "Y" splitter to feed L/R speakers?

Yes Sir... that's how we set up if we'll be running both sub cabinets. :)

I was looking at one of these to convert my mixer output to mono.

Why listen from one ear or see from one eye when the sounds and sights are so much better with a pair/stereo?
Some amps don't like it when the load becomes unbalanced!
Listen to the Extended version of "In The Air Tonight" by Phil Collins in stereo and then in mono and tell me which one sounds richer/better?
Again, to each his own. I am NOT a fan of mono!
 
With stereo when you have your speakers 15-30 feet apart the only people on the dance floor that hear the left channel and the right channel are the ones dancing in the middle of the dance floor. The ones dancing in front of the left speaker hear the left speaker, the same for the right side.

Phil Collins might sound better in stereo in your house or in your car where it is quite, but on a crowded dance floor with people talking (yelling) it is another story. If you want everybody to hear everything from the left and right channels you either have to go mono or have 4 mains and have a left and right main on each side of you.

I really like my stereo in my truck (Bose) and my home stereo but it is a controlled environment without all of the noise you find at any dance I have done.
 
I will still feed a dual mono signal to each amp. 2 channels for mains from one amp. 2 channels for subs from other. I am looking at it from an easier to control and dial in stand point for larger venues with higher volumes, where many of the nuances would be missed anyway. At the rate I am going I am going to have 2 complete rigs in a little of no time.

That is why I have the following:
Elevated highs and mids in the air.
Lows on the bottom.
The further apart means that the venue is larger which equals adding more firepower in the air and on the bottom.
I did the comparison in a crowded club atmosphere (Just knew that someone would go there)
If folks are using just DJ gear and turning up an amp just to get volume and be heard, of course yer probably need to run mono then!

Here is how I hook it up:
Source Signal (CD/MP3 Players, Laptop Output/Controller Etc)
To
Compressor/Limiter
To
EQ
To
Crossover
to
Mid/High Output From Crossover to Amp to Mains
And
Low/Sub Output From Crossover to Aphex to Amp to Lows/Subs

That sounds out of wack to me. What if I bump up the bass too much on the eq, wouldn't that defeat the compressor? Just curious why you would hook it up that way.

The compressor limiter controls the incoming signal (A mike can send a peak signal if someone screams into it) after the C/L does its job it goes to the Live Mixer (Sorry, I did forget both mixers from my previous post) in the chain, the mixer then sends a clean signal to the EQ which is used for tonal balances in the room, then to the crossover which separates the signal 2/3 way depending on what you have then the amps amplifies those signals to the speakers.

When I am doing just DJing I do not use my Live Mixer or Compressor/limiter. I can pretty much control the gains coming from my DJ mixer going to the EQ to the crossover to the amps.

I do some karaoke so the compressor will be good for that. I am mainly looking at the difference in bass responce song to song. I can usually go all night no prob, but every once in a while some heavy thumping will make my amps clip so I have to do the O'Sh** and back the volume down.

That is mainly what I want to avoid.
 
Been a while since this was posted, but just wanted to say "You were right!' I melted the voice coils on 2 15" pushing the exciter too hard. I gave up on that aspect and added more drivers to accomplish what I wanted.
 
Good to see you back. You learned an expensive lesson, eh! How much did that cost?

I would have gone with the DBX 3 way stereo Crossover instead.
be careful with your settings on the crossover, Aphex and EQ as collectively set in the wrong positions can wipe out your drivers.

The problem with aural exciters and maximizers you can get greedy and even if your amps don't show any clipping you'll burn the drivers real fast.

Just look at it as growing pains :)
