bigash Posted October 31, 2010 Share Posted October 31, 2010 At our gig on friday, we wired up the P.A. and on powering up noticed that only one side was working, not even any hiss could be heard. Changed speaker leads, no change. Then tried changing power lead which blew circuit breaker, re-set it and tried new power lead again still nothing. So we ended up using the damaged speaker as a bass bin in satalite mode off of functioning speaker, worked fine. Does anyone have any idea where to start looking for the problem. Will it be on the xlr input. p.s speakers are HK Aktors Thanks in advance Ash. Quote Link to comment Share on other sites More sharing options...

What sort of setup do you have? Mixer amp/ powered mixer or separate mixer and power amp? If it's the latter, check the patch cables between desk and amp, swap them over and see if the problem moves to the other speaker. If it does, the problem's in your patch cables. If that makes no difference, swap the patch cables [b]at one end only [/b]and see if the problem moves. If it does, the problem's in your mixer, if not, it's your amp.

ironside1966 Posted November 2, 2010 Share Posted November 2, 2010 My advice to you would be check all the fuses plus the mains lead, as I can gather from your post the speaker is working so if it is not a fuse it needs to go in for repair, as to what it is I doubt if you will get an answer without someone qualified having a look. I think the PA is active speakers so do the cabs fire up? If Yes check inputs with a mic or CD,MP3 player if no, check all the fuses plus the mains lead, as I can gather from your post the speaker is working so if it is not a fuse it needs to go in for repair, as to what it is I doubt if you will get an answer without someone qualified having a look.

Re-set powered up ok again but still no sound. We then wired it up as a bass bin from other speaker worked fine. I think it must be a problem with xlr input.

HTH A We have powered speakers, wired straight into desk. tried different cables, still dead and new power cables, still no sound untill we used the speaker as a bass bin which requires the use of a different input, so i suspect the original input is where the fault is.

ironside1966 Posted November 2, 2010 Share Posted November 2, 2010 I would think it’s the amp as there is no sound from the speaker and if it was the input there should be a slight hum or hiss, unless the other speaker is silent without anything plugged in Quote Link to comment Share on other sites More sharing options...

If it was the amp, surely there would be no sound when we wired it up as a bass bin either. but it worked ok then. Quote Link to comment Share on other sites More sharing options...
ironside1966 Posted November 2, 2010 Share Posted November 2, 2010 (edited) What do you mean by satellite mode? Are all the speaker cones working? But it sounds like they are If my memory is correct the Actors are 3 cabs a side, active bin, a passive bin and a mid top active box, I beleave the crossover for the subs is in the bin itself not 100% sure though. Is the mid top cab ok without going through the Subs? You could take the amps out and check for any loose connections and blown fuses anything other than that use a qualified engineer. It also could be the crossover. Edited November 2, 2010 by ironside1966 Quote Link to comment Share on other sites More sharing options...

What we where using is a pair of full range active speaker[see below].One of which did not work in normal full range mode. But when linked to the other working full range speaker as you would if it were a bass bin worked o.k. although not full power as it was acting as a bass bin. I hope this clears up any confusion.
