signal processing?

[djeccentric]

what are you using to process your audio signal. i was planing on runing from my main outs on my mixer to a 31 band eq, then 2way crossover, then 4 channel compressor, then to the amps. do you think this would be a good setup. anything i should add or don't need out of this setup?

thank you

The 4 channel compressor doesn't make sense in the equation.
What is your intentions with the compressor?

The rest sounds ok, but adding anything else depends on what speakers you are running.

[djeccentric]

sorry the 4 channel compressor is for L/R low leading to the sub amp and L/R high going to the mains amp

[Doug Hart]

Sounds like you're making it a little more complicated than it needs to be.
If you are running signal to a 31 band EQ, then to a crossover, then splitting 4 channels to go to L/R mains and L/R subs... you are still getting a mono signal.

Personally, I wouldn't use a compressor on the main mix. I only use compressors on channel inserts.
Others may disagree here, that's just my opinion.

Still, if you want to compress the main mix, you don't need to use all four channels.
You just need one channel for mains and one channel for subs.
Save the other two for channel inserts.

In fact, you could just use one channel of compression and have three for channel inserts.

(EDIT)Mixer out to EQ, EQ out to Compressor, Compressor out to crossover, crossover out to mains and out to subs.(/EDIT)

Does that make sense?


More information would be helpful to assist you in setup:
What type of music? Live or recorded?
What mixer?
What amps?
What Speakers?

i'm not sure what you mean by still having a mono signal. the mixer i am using is a dj type with L/R out via 2 xlr cables. the EQ and Xover i am looking at are two channel input each.

i am using a phonic xp2000 to power two kustom ardent 15s for my main speakers. i am going to have a xp3000 to power two titan 48s.

i would be playing recorded music and live electronic music.

Ok, that makes more sense.
The way you described your setup will work fine.
Mixer L/R to EQ Ch1 & Ch2 - EQ To Crossover - Crossover outs to Compressor Channels - Then to amps.

Be sure to engage the 30hz HPF on the XP 3000, and engage the limiter.
You might also consider using the compressors for the subs as limiters.
You don't need the compression for recorded music, but you do need limiters on the Titan 48's.

I'll agree on everything but this part:

You don't need the compression for recorded music, but you do need limiters on the Titan 48's.

If you'll be the only DJ using this rig, then you should know your gear well enough to not need compression. If this is for a typical electronic music event where you'll have several different DJs stepping up to play, then compression is a HUGE help. When a standard DJ mixer has +12db capability on Lo/Mid/Hi EQs for each channel, it becomes very easy for a DJ to take a system well beyond its capacity. While a brickwall limiter will keep your speakers intact, a compressor will keep the music sounding (relatively) good while you take your time and mosey back to the soundboard to fix things.

If you don't already have these, then save the rack space and knobs that are too easy for idle hands to "play" with by getting a DSP that does all that and more. The Behringer DCX2496 is pretty popular around here: it's got EQ, more crossover options than any analog one will have, and output limiters all in one rack space. Presets for common setups or venues are icing on that cake. Any other DSPs probably cost more, but will let you avoid the Behringer name if that's a concern to you.

I missed that part.
Yes, definitely go with the DCX2496.
That's what I use and it works great.

[djeccentric]

well i do appreciate the suggestion of the digital signal processing unit. in a live situation i am a fan of having a button or knob for everything so i went analog.

Nice rack...

[LelandCrooks]

Nice rack...Quit acting like a boob! Can't you see tits just dirty pictures from your mammary that's causing you to think like that? I don't give a hooters about how a woman looks, tits only her mind that's important. So, don't be a jugshead.

Tatas for now.....

Upon which subject Bruce is eminently qualified.
