Coping with big rooms

Postby gsc1ugs » Sun May 26, 2019 8:10 am

I did my first suggs tribute last night and the inevitable happened, huge room in a posh gaff, my question, the volume on dxr15 can it be pushed to max? Second, i saw in this room a pair of rcf acustica subs on floor part of the hotels music system s4012 model, have any of you heard these? I do need a pair of subs for these larger rooms so looking for compact (transport issues) pair of subs. Cheers

Ps: gig went well

You shouldn't risk damage to the DXRs by winding the volume up (but make sure the mic/line switch is set to line) as they will look after themselves but avoid audible clipping/distortion and watch the clip lights on the speakers fo excessive clipping.

Subs will help though I'd go for a single good sub in preference to a pair of average ones. But, bear in mind that at most function gigs the punters at the back want to be able to talk so, even where the genre is one that would usually be played loud, extreme volume is not necessary (and may lead to complaints).

FWIW I could get a full band PA, including a 15" sub, into a Golf, that was 5 x tops, 1 x sub, mixer, mic stands, mic box, two tubs of of cables, a couple of guitars and a guitar amp. Still with room for a passenger.........

Glad to hear the gig went well :clap: :clap: :clap:

Hi, this is my first time on SOS and I could really do with some advice. I do the sound for my wife’s tribute band and when I do a big room and I push the pa hard, I keep clipping the amp - one time actually making it trip off! I have a Peavey rig with a 2.6k amp, 15” subs with built in crossover and 12” tops. I bought a crossover and a 1.4 amp to try and run the subs with the big amp and the tops with the smaller amp and when I put music through it sounded ok until the girls started singing and they sounded awful. So my question is this- am I doing this wrong? Should I buy a bigger amp and could this damage my speakers, would a bigger desk make a difference (with bigger Chanel pre-amps?) or should I invest in some powered speakers and link them out of the desk(someway) to get a greater overall sound without driving everything to hard? As you can tell I am no professional so please go easy on me, any advice is greatly appreciated

Mark, the answer isn't a simple one. When you say 'big room', what are you talking about? You are running a 4k rig, so you should get sensible volume levels. I don't think a bigger desk is the answer - if you have enough gain in the mic pres to get a healthy signal into the desk, then it's doing it's job. You are correct to worry that bigger amps might be bad for the speakers - it depends on their specs. What model speakers do you have (and amps for that matter)?

I'd also be a tad curious about the mix balance if it sounds fine without vocals. If their addition is causing problems then it sounds like you may be pushing them too high in the mix. Caveat - assuming you are running everything through the PA! How much of the backline is used for the sound and how much / what is going through the PA?

Also, what do you mean by 'sound awful'? Is it the overall sound of the PA? (ie, the whole mix) Or just the sound of the vocals?

Hire in an experienced engineer and rig for the big rooms. If you tell them the size of the room and what sort of material you play they should bring along an appropriate size rig which will probably be better quality than yours. You can also take the opportunity to pick up a few tips which you can apply when you run your PA for the smaller gigs.

Thanks Dave for your reply, to answer your questions I am using Peavey pro mkII speakers ( apologises I put the wrong size speakers down on my first post, they are 18” bins and 15” tops” ) the amp is also a Peavey 2.6k amp. I haven’t yet used the other (thomann) 1.4k amp to run the tops as when I set it up through sound check that’s when the girls sounded like they were singing under water, that’s what I mean by awful, the keys and backing track had a nice sound but when I put them all together it just sounded dreadful and I just couldn’t do anything to get it sounding right. It was the first time I had used the crossover and I had it set at about 100db and I though it was going to be ok when I played the keys through it, it sounded like it had a nice range, but then I added the voxs and it was terrible. The back line is just a couple of powered monitors through aux 1. Do you think I was doing something wrong with the the cross over or even doing something wrong with the desk? One of the girl singers sound checks quietly and then belts out the sound through the show so I never have the mic gain quite right. I always try and get the pfl signal in the green touching on the yellow, is this too high as when she sings it’s she pushes it into the red? Where is the correct place to set it? Thank you James for your reply and I would love to hire a professional sound engineer in but then that price when probably double their fee! I’m afraid I’m all they have which is why I need your help.
