lx999 Posted October 3, 2013 Share Posted October 3, 2013 Hi, just picking your minds, the problem is this; while I was away doing a show, my local village hall decided to go ahead and install four Control 1's that we had bought to upgrade the background/ambient sound set-up. Unfortunately they connected them (all four in parallel) to the 100v line system, and when they sounded a bit odd, cranked up the volume until they sounded really odd.My best guess is that they've fried the crossovers (there is almost no bass), but it is only a guess. I notice from my researches that they have some protection on the crossover (a sort of glass fuse), would replacing this be my best bet. or should we just abandon the speakers and start again? They were zumba'd to death before anyone thought to ask : ( thanks folks, try not to snigger : ) Link to comment Share on other sites More sharing options...
Brian Posted October 3, 2013 Share Posted October 3, 2013 Which version of Control 1s do you have. AFAIK there are at least 3 - vanilla, X (extreme) and Pro. Link to comment Share on other sites More sharing options...
Simon Lewis Posted October 3, 2013 Share Posted October 3, 2013 There was a Control 1 100V line version, but I think that may be discontinued. It's quite possible you have damaged the speakers, or even the amplifier. I would check both... Link to comment Share on other sites More sharing options...
Rob_P Posted October 3, 2013 Share Posted October 3, 2013 Hmm. 4 Control 1 Pros in parallel would give a 1 Ohm load. That could get exciting for the amplifier! I'm amazed that it worked at all. Can you try the amplifier on some known good 100v speakers? Link to comment Share on other sites More sharing options...
lx999 Posted October 3, 2013 Author Share Posted October 3, 2013 Hi, they were/are control 1 Pro. Amp seems to be fine, I connected it to a 100v line feed that does a breakout room and sounds as good as it ever did. I'm still thinking that the crossover is most likely to have suffered, but subsequent researches reveal that they have some protection, so I think I might try replacing that first.

Brian Posted October 3, 2013 Share Posted October 3, 2013 Just how powerful is the 100V amp? The control 1 pro is quite a tough little speaker and most 100v amps aren't that powerful. Link to comment Share on other sites More sharing options...
lx999 Posted October 3, 2013 Author Share Posted October 3, 2013 I'm not sure, it's a Philips mixer jobby, and about 75 miles away. So I won't be able to check for a while. I suspect any amp, if it's being tortured as this one was, is likely to cause problems. Link to comment Share on other sites More sharing options...
Jivemaster Posted October 3, 2013 Share Posted October 3, 2013 I'd want to check the amp before messing with some speakers. Unless it's a very well protected amp the low load has probably impaired it's performance! Link to comment Share on other sites More sharing options...
lx999 Posted October 3, 2013 Author Share Posted October 3, 2013 I have checked the amp, and it appears to be ok (see earlier post), as we're proposing to replace it, I'm not that worried about it to be honest. Link to comment Share on other sites More sharing options...

Owain Posted October 3, 2013 Share Posted October 3, 2013 I'm not sure, it's a Philips mixer jobby, Probably about 60W then; later branded Bosch Plena, there are a couple in my local Cashgenerverters. Link to comment Share on other sites More sharing options...

The engineer is about 75 miles from the mixer, who says noise boys have no sense of humour : ) Link to comment Share on other sites More sharing options...
fincaman Posted October 5, 2013 Share Posted October 5, 2013 You have two problems here excessive voltage applied to the speakers which can damage them even if the amp is lowish power and a very low load impedance presented to the amplifier. Check the speakers on a known good amplifier and or check the amplifier on a known good speaker but be careful as there is a risk of damaging the good equipment Link to comment Share on other sites More sharing options...
