Weird problem

bluesonics

One of the clubs my band plays in has a pair of Yorkville Performance Series cabs hanging from the ceiling. They have a little junky powered board. I prefer to use my rig with my DRPA and Yamaha 7000 amp, and Mackie board. I have connected to their speakers and can't get any reaponse from them, yet I do get response from my sub off one of the amps. When I plug ther speakers back into their board they work, but sound crummy. I have changed cables from the DRPA to the amp, I have changed cables from the board to the DRPA, but still get no sound from the Yorkvilles. All the while my sub is working. I am using the same set up, other than the JBL setting in the DRPA when I use my own speakers, with mains set as custom, and sub set as custom. I have double checked the cabling from board to DRPA, to amps, to speakers. Any suggestions? BTW another club that we play regularly has a similiar set up with mounted speakers. I use my rig and connect to their speakers (Fender 12\" cabs- real low volume club) and it works great.

Their speaker cables or yours?
Speakon, banana, or 1/4\"
Signal at your amp?

Could the speakers possibly be cooked? Small crappy powered mixer... pushed way to hard...What model Yorkies? Possibly fried crossovers? Possibly bad input jacks to crossover connections, It doesn't take movement for the solder joints to go bad. Your going to need to feed a known good speaker signal to then if it's still crappy you'll need to get them down and find out whats gone wrong...

their speakers, 1/4 phone plugs, my speakers work fine on regular set-up their speakers work fine on their board, just under powered so the sound is thin.

bluesonics

Yorkies are performance series, three or so years old, 15's and 1\" horns mounted too high to read actual model number but they appear to be the Y150, 300 watts 8ohms

Gadget

Well, they'll have to come down and see whats wrong with them then..

we're missing something here. the speakers work when connected to the house board and power, they are just under powered, so they don't sound very good, but they do work. if I bypass my DRPA, they work. my sub works through the DRPA, but the mains will not. to get through the gig i sent a signal from the pan right setting (right channel)on my board through the DRPA, amp and sub (sounded great as usual) I sent signal from pan left (left channel) on my board to their amp and mains. it worked ok, but would have sounded better through my DRPA and bigger amp.

Gadget

Well, we'll need a lot more info then...
what setup and outputs are you using in the DRPA Include all pertinent info, crossover point, type configuration, etc...
is the speaker plug for the house tops 1/4\" phone jack
have you verified cords from DRPA to amp
what happens if you run another speaker (yours for instance) off the same output that you send to the house speakers?
are you panning for some reason? The house mains are mono right?
the more info the better.

since the house speakers are not in the presets i set them to custom on the set up wizard. My amps are not in there either so they are set for custom as well as the sub. through the wizard, i set up stereo linked. the cables are good between the DRPA and the amps. the cables to the speakers are good also. this is why this is so puzzling. everything looks right, but when i try to use their house speakes with my rig i get nothing. if i bypass the drpa i get sound. doesn't make any sense to me.

bluesonics

i'm using their cables to their speakers and they are 1/4\". my speaker will work out of the same output. i'm using the left high output for the mains and left low output for the sub. the speakers are plugged into the output channel of the amp. i only panned to be able to use my sub from my power, and send a signal from my board to their house system without the low end for kick drum and bass through the foh speakers as they would sound bad with the low end coming throught them(not bad enough to indicate that the speakers were blow) normally would not pan at all house mains are mono.

Gadget

Ok, but when you select 'custom' it doesn't set up the crossover...so what did you set it up at? A custom 2x3 would have the L/R hi outs as the tops and the left lo out for the sub. A 2X4 would send the L/R tops out to the L/R hi outs and the L/R subs out the L/R low outs. But again the crossover is not set up...With a 15 \" an a good amount of power for them I'd probably set a hipass for the top/sub interface @ 100 hz, if the power is inadequate closer to 120 hz.. the hipass for the subs would be dependent on the 3db down point for the subs and the amps power. You didn't provide any of that info...and yes it's germane to the issue...and info I asked for.

So for instance, if you were running fullrange on the tops and subs, and the subs and tops were wired backwards.. (in other words a 9 volt battery applied to the tip of the plug + and the sleeve of the plug to the - terminal should drive the cones OUT ...unless some JBL drivers that are reverse wound were used)....
then anything in the low- low mid would cancel...as the sub goes OUT the 15 inch in the Yorkies goes IN...guess what... WEAK sound...
Sound familiar?

Hi bluesonics

I'm with G here. More info needed
What equipment are you using??
Both your gear and house system (including the \"little junky powered board\")

Please supply links to the equipment's web sites, as this helps visualise how it is wired and which outputs you are using

1 question
If you were to setup the system, as you think it should work, you don’t get a signal though, if you were then to put your speakers into the same setup do you get sound???

Hey fannie.. nice use of color... did you get my PM?

Fanman20

Hi Back

Thought if Dra could use colour than I would give it a go

I have returned your PM with my PM which is still sitting in my outbox unopened.
Must mean you are not getting notices???

They're looking into it.. and that would be a no.. I wasn't notified..

ok, here;s my rig:
Mackie CFX 12 board
DRPA
Yamaha 7000 amp
Mackie 1400i amp
2 JBL JRX15 speakers
2 custom made sub cabinets with 18\" 800 watt speakers modeled after JBL JRX118

my rig works as is and with the same set up I did not get any sound out of the yorkies with them plugged direct into my amp with their cables. When I plugged their speakers back into their Yamaha powered board (250 watts per side I think) they worked.

My setting on the DRPA is 2X3 with crossover split set at 100. I have done the manual gain setting, but I can't find a place through the wizard to set the amp sensitivity. What did I leave out?

Fanman20

Ummm

Still not making cents ?????


Still trying to work it out.

Try some different combinations of equipment

Try eliminating possibilities one by one
Any more info will help, on matter how small

i checked my cables again last night at home and all the cables that I have been using are ok. the yorkies seem to be pretty normal cabs, but I ccan't get any sound out of them using the DRPA. how could the crossover cause problems where it is set as Gadget suggested? would it just make it sound really bad?

Gadget

Try reversing the polarity on the subs or the yorkies.. whichever is easiest...that means on one plus to plus and the other plus to minus..of course hook up the other wire to the other terminal...then tell me what you find.

Oh I guess you should tell me if it sounds bad even without the subs on your rig...that means the Yorkies to your system.. no subs... you'll have to run the crossover down to 50HZ or so...check that the compressors are off.. the PEQ's are off and that the GEQ doesn't have a lot of cuts either.

bluesonics

Thanks, I'll try it and let you know.

I have always used the wizard for set up. Using the custom selection for my amps I don't get the option to put in the amp's sensitivity. How can I do that or does the manual gain setting do basically the same thing?

Gadget

Unless your a \"Died in the wool\" (there you go David...) purist, or tech snob there is no absolute right way to do it.. the thing is that here.. we are dealing with \"newbie\" to \"novice\" level primarily.. so for simplicities sake we profess the \"gain structure\" method of amp setup.. that is, leave the Driverack levels somewhere around unity gain and use the amps controls to determine the final setting...Now if you are running a fullrange system and you want to \"get it right\" look up the specs on the amp in question... there should be a spec... be it .775 volts, or 1.23 volts.. and find another amp in the menu that has the same sensitivity and go with that. Or set it manually. The thing were looking for is the best signal to noise ratio we can get.

Gadget

bluesonics

Thanks. That is what I thought, but I want to be sure I am getting the most out of my system. My Yamaha is .775 and the Mackie (when I use it) is 1.23, but I have done the manual process for both. Thanks for clearing that up.
