Hi everyone, first post so please be gentle with me, looking for help with my current 3 way set up am running bass, adlib audio aa15 x2 400w 40-200hz,
mids, wharfedale lx15 x2 400w 40-20000hz, and tops, wharfedale lx15 x2 400w 40-20000hz, bins powered by crown xs900 600w per side @ 8 ohms, mids powered by crown xs 900 600w per side @ 8 ohms, tops powered by crown xs700 450 a side @ 8ohms, was wondering what would be the best xover frequencies, and i assume 2x6 would be best set up thanks
mids, wharfedale lx15 x2 400w 40-20000hz, and tops, wharfedale lx15 x2 400w 40-20000hz, bins powered by crown xs900 600w per side @ 8 ohms, mids powered by crown xs 900 600w per side @ 8 ohms, tops powered by crown xs700 450 a side @ 8ohms, was wondering what would be the best xover frequencies, and i assume 2x6 would be best set up thanks

You list the same cabs for mid's and hi's. Or are you bi-amping the same 2 cabs?

am running two seperate sets of the same cabs for tops and mids
system is driving a 4 piece celtic rock band, so tight and punchy sound rather than booming bass really
thanks
As for the tops, if your going to run stereo we run into the same problem... limited power, but with 4, 8ohm speaker ( unless you have the 4 ohm models...see what I mean about information.. it's all relevant to the process...) the only option is stereo, however the crossover point could be changed depending on power available.
So finish filling in the information and we'll go from there...

reading between the lines....
seano321 are you thinking of running 1 x wharfedale per side for mids and 1 x wharfedale per side for tops???
eg
DRPA mid left out to 1 x wharfedale
DRPA mid right out to 1x wharfedale
DRPA tops left out to 1 x wharfedale
DRPA tops right out to 1 x wharfedale
If so we need to talk more..... :?
More info on how you intend to wire it would be nice

Dra I don't think that they have bi amp capacity!
We can talk you though the best set up but need lots more info on your set up
There appears to be two models
Do you have the 4 or 8 ohm model????
Mark
Both sets of Wharfedales are 4 ohm
yes was thinking of running one mid and one top on each side, one amp running two bins,one running two mids and one running two tops
adlib audio bins are 8ohm
wharfedales have a link and an input
What do you mean by
Please tell us step by step how you are going to wire the DRPA to the amps to the speakers.
This is very important because I don't think what you are planning will work.

Known facts
4 x Wharfdales 2 x aa subs 2 x crown xs900 1 x crown xs700
left and right low on dbx to left and right on xs900
left and right mid on dbx to left and right on second xs900
left and right hi on dbx to left and right on xs700
then send leads from amps to corresponding speakers
All amps currently running in stereo
Sorry but It won't work.
The best setup (with the knowledge you have) is a 2 way setup
Will post how later, unless the boys get in first
Mark
You need to do one of two things.
1) Run the Cab's just like they are with their internal x-overs. Either all on one amp or 2 each on the 2 amps.
2) Pull the int x-overs, make cover plates with 4-pole speakons for biamping.
DRA
If your suggestion that you run 1 pair of fullrange tops as mids off one amp and the other set of fullrange tops off the other amp as hi outs... were in a lot of trouble here...that seems to be what your telling us, that you want to split the signal into lo mid and hi frequencies and have one set do ONLY midrange sound, and one set do ONLY hi frequency sound... it doesn't work like that...Your best bet is to just run a 2X3 and feed both sets of tops off the one 900 as a 2 ohm stereo setup Hi outs from the DRPA to the XS 900 A output to one daisy chain pair, and B output to the other...but again, we still don''t have enough info. DO THE SPEAKERS HAVE A PARALLELING OUTPUT? If not you will have make up a jack panel at the amp rack with wires that are tied together at the binding posts...2 speakers per output. I hope you have good power because if your running @ 120 volts those 2 amps could be drawing nearly 40 AMPS of current!
What we need from you is to understand EXACTLY how you are hooking up those things...a sentence or two just isn't doing it here... You seem to be saying that a fullrange speaker can serve as ONLY a midrange.. or ONLY a tweeter and if thats the case you really don't have a clue whats going on here...

Set up a 2 x 5 (stereo in, stereo Hi & Mid outs, plus mono sub)
NOTE: The mid outs are only used if you wish to add the 2nd set and want a bit of control over them (PEQ, band-width filters, limiting, output gain, etc). The Mid x-over section typically would be set to match the Hi section or possibly crossed higher for more upper range coverage if needed, etc, etc. If you don't need them, don't connect them.
Subs: Bridged XS900
HPF 40 - 45 hz @ BW18
LPF 100 - 120 hz @ LR24
Mids (optional tops): XS700(?) stereo
HPF 100 - 120 hz @ LR24
LPF - 18K (or out) @ BW12
Hi's (Main tops): XS900 stereo
HPF 100 - 120 hz @ LR24
DRA
from the dbx to each channel of the xs900, and would i then link the the 2 mids with each other and the two tops with each other using the parallell inputs on the wharfedales and if so what fequencies am i best splittin them at, oh and am i running the bass bin amp bridged mono and linking the speakers, sorry for all the questions
To parallel the input (same signal to both sides of the amp) just plug into channel 1 as usual and jump out of channel 1 into channel 2 with a short mic cable. No need to buy a special cable.
DRA
This is what Gadget was saying.
DRA
As for the \"Y\" input ....Why even do that? Send L/R out of the mixer to the DRPA, Set up a 2X3 send the left hi out of the DRPA to input (1) of the XS 900, send the right channel out of the DRPA to input (2) of the XS 900. this will then be considered a stereo full range 2 ohm configuration which this amp can do if NOT OVERDRIVEN!!!!!GAIN STRUCTURE HERE IS PARAMOUNT!!!!!
Get 4 each NL4 pannel Jacks:
http://www.fullcompass.com/product/297822.html
and a few feet of wire...connect channel (1) (crown amp) red binding post to two of the Pannel jacks on pins 1+ the Channel (1) Black binding posts to the same NL4 on pins 1-. This then is a parallel connection, so two 15X2 speakers will be run off these 2 jacks and can be run using readily available speaker cables..
The channel (2) binding posts will be routed in the same way to the other 2 NL4 jacks to run the other two 15X2 tops, again using pins 1+ AND 1- respectively just like we did above...Now we have the tops run off the ONE xs 900
The other XS 900, you will slide the Normal/Bridged switch between the 2 Neutrik connectors down to bridge position. Plug the MONO (L) output of the DRPA into the #1 input of the amp(although the amp parallels the input in bridged mon anyway...)The BEST way to do this is to get 2 more of the( http://www.fullcompass.com/product/297822.html) and wire BOTH NL4 plugs to the RED terminals... Channel (1) binding post to BOTH NL4 jacks PIN1+, and BOTH NL4 pins 1- to the channel(2) binding post....(this is important!!!!! make sure you match the polarity to insure all speakers are working TOGETHER... not fighting each other) this will then have both subs receiving the SAME amount of signal, jumping from one speaker to the other is a good way to FRY the first speaker in the chain!!!!!
So if the mixer is then left with all channel strip PAN controls centered, each speaker will receive a summed mono signal anyway...AND if you are running stereo effects like reverb, and returned on a stereo channel, or to two PANNED channels those effects will be in stereo and add some life to the mix. Again, this would be considered a parallel bridged MONO setup @ 4 ohms... your amp can do this but AGAIN....GAIN STRUCTURE IS PARAMOUNT, and DO NOT OVERDRIVE THE AMPS!!!!!

I posted this just before going to bed...
A few hour later, (10 posts later) and you have an answer. I missed all the fun
(I need all the beauty sleep I can get)

Do you understand why it won't work????
It won't work acoustically (it will work electronically but will sound very bad) That’s the big difference.
Mark
321, Do you understand?
DRA
The wizard will recommend where to set the x-over gains and the amp attentuators. However, it is preferred that you follow the procedure detailed in the welcome area. It will be a great learning experience to do it manually and compare what it says with what the real world (you) says.

Seano.,,, there are no shortcuts here... you need to do the reading and get up to speed on what you don't know here...I know they portray the Driverack as a \"hook it up and the rest is instantaneous and automatic\"... it ain't so!
