New Pa System! Help needed please!

[ilovejam]

So im looking advice from anyone with experience with PA systems please.

My band is looking to buy its first PA system. We play mostly rock music(kings of leon, foo fighters, mgmt etc..) and we have around €2500 to spend. Unfortunately I have been left in charge of piecing together the equipment but I have no experience at all with PA systems! From looking around online I believe the best choice (and the one that leaves the most room for expansion) is an anologue mixing desk, an EQ, a crossover, a bass amp with two subs and a mid/hi amp and two full range speakers with tweeters and two active floor monitors running from the mixing desk (or is it better to run it from the EQ?) My main concern is with the amps and speakers/subs, do the amps match them or will they be under powered or overpowered or what?!

The different pieces of equipment I have chosen are:


LEM RDX204 Mixer with 12 mic inputs,

BEHRINGER DEQ 1024 DIGITAL EQ

DB TECHNOLOGIES ASX 18 crossover

for the speakers BEHRINGER EP2500 EUROPOWER amp. 2x 750watts at 4ohms, 2x 500watts at 8ohms, 2x 1200watts at 2ohms, bridged 1x 1500watts at 8ohms, 1x 2400watts at 4ohms (1 kHz @ 0,1% THD, both channels driven).

The Speakers themselves: BEHRINGER B1520 EUROLIVE PRO - 2 way full range speaker system (1x 15" & 1x 1" speakers), 400watts (RMS), 800watts (peak), 8ohm.


For The subs: BEHRINGER EP4000 EUROPOWER
Behringer EP4000 EUROPOWER amplifier - 2x 1400watts at 4ohms, 2x 750 W @ 8 Ohms, 2x 2000watts at 2ohms, bridged 1x 4000 watts at 4ohms, 1x 2800 W @ 8 Ohm,

and The Subs themselves: Behringer B 1800 X Pro Eurolive Performer - 18" sub bass, 450 watts (RMS), 1600watts (peak), 8ohm, 100dB (1watt/1mtr).

Finally the floor monitors: THE BOX MA150

can anyone with knowledge of pa systems please check these figues and make any recommendations please! also with this systems obviously vocals and the kick drum can be run throught the pa and i have been told that keyboard and acoustic guitar are plugged into DI boxes and then into the mixing desk but what of electric guitars and bass? can they be run into pedals from the pedals to DI boxes and into the PA or is it better just to mic the amps? a friend also told me for the bass to run the pedal into the DI box and from the DI to pa and a bass amp and just mic the guitar amps? as we dont own very big guitar or bass amps is it possible just to run everything through the pa and not bother with seperate amps for each?

I am very thankful for any advice you can give!

NO need to double post. Please delete your other one.

I'd probably go active in your situation. Mackie Onyx desk, a pair of Mackie 1530s and a single sub. You can add further subs and or tops later as your budget allows.

sorry totally new top this how do i delete the other thread? and thanks ill check them out now.

Any advice on running the bass and electric guitars through the pa?

and if we do decide to go with the seperate units instead what size amp should be put with what size speaker? If the speaker says 400/800 watt rms/peak should I get a 400 or 800 watt amp to power it?

DI the bass. Mic the guitar.

I'd expect to see an 800w amp (running 8ohms) powering 400w rms drivers.

Hi
I agree with previous post bass should be D.I'd. I use a DBX DB12 active d.i box and it hs been great.
For electric guitars I use SM57 mikes off their valve combos and also for the lead guitar I use an addtional input via a Hughes and Kettner Classic Red box which takes a hot (speaker) feed from combo amp. Mixed together it sounds great and the red box has a nice cabinet modelling feature which improves the sound. Many recording engineers apparently use this dual feed when recording lead and rhythm guitars a mix is very flexible.
Hope this helps.
