In Topic: Rig setup - expansion - need advice

20 March 2014 - 10:33 AM

Sorry to revive this but I need to gain some knowledge.

With our rig (2x yamaha s215v rated at 1000w RMS) and 602's bridged (not sure the max... I think 1200).

Am I adjusting the output wattage of the amp - thus to the speaker - by adjusting the attenuation on the amp?

so when I peak the amp (setting it's max input) and the knob is, say at 2 o'clock, am I running the amps at 75% or say 800watts?

In my mind... I think of that as the "gain" knob on the mixing board. You're bringing the signal into the amp, you're allowing the max signal to come in before going out. Correct?

I think I read somewhere that amps are amps... their rating is their rating and that's what they output no matter which way you turn the knob. Right or Wrong?

So if I peak the amp with pink noise to set max - what am I actually doing? Amy I setting the actual wattage output? So are my Yami's only getting 800w vs 1000+ of their capability?

I'd like to understand this to put some arguments to bed and be able to explain it in layman terms.

Thanks for the link. I think I did read that somewhere before and I'll take it more seriously as I think we've experienced that to some extent. It's really good information.

So are you saying doubling our rig isn't worth it? We can get a pretty good deal on the subs, but it's till a good chunk of change.

Avi... thanks for your $0.02!!! It is greatly appreciated (and worth more than 2 bits!). You are right, we do need a biz plan in place for this. I think our main thing is is to be able handle up to a certain size on our own. We're at the point where we'll be bumping our rate and it may be more feasible to hire production at certain price points; but right now we're kind of at that mid point where it makes more sense to handle certain gigs ourselves rather than walk away with almost nothing after production, booking agent and paying the band - what's left doesn't cover the bills.

As for the subs... right now we only have 4 of the K181's... so typical shows we just side stack, if a stage or larger venue is involved we'll run them across the front. I hope to double them so we can push a bit more air and have some flexibility.

Awesome... thanks Alain! That eases my mind a bit. Since the QSC's are all powered subs we also only sending 100hz on up to the Yamahas... so not too much low end is hitting the tops.

We do have a nice sized rolling rack (thank God) that we're going to start using so we can house those amps. I'll be sure to allow for adequate ventilation.

Thanks for the response dakos!

Good questions and I'm not exactly sure how to answer. I'm guessing a little of both. Outdoors we're talking county fair tents, street festivals. Maybe max 500 people and about 20+ feet from the stage. It could really vary - but we're not talking stadiums here. We typically play local bars, venues but come summer the outdoor gigs pop up and I'd rather have the capabilities to do the show myself verses handing over half the gig to a production company if we can't help it.

Does what I propose doing make sense? will those 602's bridged keep up?
