Karaoke Forums

hello, newbie here.tnx in advance for all the replies.. hello to everyone as i'm a newbie and this is my 1st time to post here.i've been assigned to install a p.a system in our local community center with emphasis on clear vocals for speech and karaoke applications with a/v presentations at times.the budget is roughly around 2000 dollars.the area is approximately 2500-2700 sq ft. with a stage in the middle.the capacity of the hall is i think 115 persons.the problem that i've heard on this place is that the current pa setup is creating a squealing feedback bcoz the r-side spkr on a stand is right behind the mic podium.i told the board of committees that this has to be solved on the new pa setup.i'm attaching a rough sketch of how the hall looks like.my main concern is to supply the hall a good p.a. system with the budget that they're giving me.i have the cd/karaoke player and all related dj cd player so these arent in the list of equipments anymore.for 2k, this is what i have in mind.i do have to give them 2 options though.any inputs form you pros will be greatly appreciated.again, tnx for looking at this post.
package 1
mackie dfx 12 mixer $250/qsc rmx 1450 amp $400/pair of ev sx80 spkrs w/wall brackets $500/ proco 8x4 100 ft snake $230/behringer autocom compressor w/gate $110/behringer stereo 15 band eq $80/carol 14 gauge spkr cable- 1/4 /trs cables $80/300 w powered subwoofer to be determined later $350.total cost of system at 2 grand.

with this in mind i came across the bmb cs500/vocopro sv500 karaoke spkrs with angled conetype tweeters.has anybody used these spkrs in a 4 spkr configuration like l/r frt and l/r rear mounted sideways,www.bmbkaraoke.com/cs500manual.or has anyone used the vocopro ssp1500 system with a pair of sv500 and a sub1200.i'm going to try to attach the hall diagram on this post.again, tnx to all that will care enough to help me out as i havent heard the bmb nor vocopro spkrs live in action.i'm just trying to help out our community center as their pa system now really sucks.

sorry guys but this forum wont let  me attach the hall diagram as it exceeds the max limit of space.

This is an easy one!!

1) Two Mackie SRM450 powered speakers ($700 each, $1400 total)

These speakers have the best highs and vocal reproduction of pretty much anything out there under $1000 a speaker. They do pretty well on the lows but really should be coupled with a powered sub in the future. At a pretty low volume, these puppies will generate mids and highs that will pierce all the way to the back of your 2700 SF room.

2) Mackie DFX12 mixer ($250).

This one has as many channels and features as you'll ever need and a good FX section for adding reverb, etc. to your vocals for karaoke.

That is $1650 for really everything you'll need minus the wiring. The feedback problem isn't particularly going to be solved by getting a compressor and an external EQ. Having better speakers like the ones above will project your sound to the back of the room better at lower volumes, which will help a ton with the feedback and after that you should be able to eliminate the feedback with the low/mid/high EQs on each channel on the mixing board without needing all of the other stuff.

Without knowing your exact problem, I'd say you need to take the bass out of the mic channels (put them to about 9 o'clock), put the highs and mids to about 1 o'clock, and drop the bass in the overall mix whenever you are just using the PA for speaking. With the speaker/singer being in front of the main speakers, it would also help if you instructed everyone to hold the mic perpendicular to the ground instead of paralell like they normally would. The pickup pattern of the mic will take in about 30-40% less of the speaker noise at that angle.

Hope that helps!!

Agree highly on equipment recommendations - i'm guessing you need the snake because you are going to have the mics on stage & the equipment in the back of the room which is fine.  Stay away from any "karaoke" speaker or speakers "designed" for karaoke - not worth the extra $$ & won't sound that great.  As far as the feedback, you need to get the speakers in FRONT of the mic, even with a good set of speakers, feedback will occur if the mic is out in front of them.   Mic quality can play a part in feedback as well.  If you get a good eq, that will help, but with the speaker behind the mic, you'll find you are going to be cutting so many frequencies & wonder where your sound went.
