Jess-- Posted February 1, 2011 Share Posted February 1, 2011 I have a few sets of the old peavey UL15 speakers and have noticed (while replacing a broken speakon connector) what appears to be a halogen lamp inside, from memory it was in series with the main driver although I could be wrong. I am assuming its there to act as a protection device i.e. when cold = low resistance but when hot = higher resistance meaning it would reduce the power to the main driver if it was over driven (hopefuly preventing damage at the cost of a blown lamp) would my assumption be correct?

Simon Lewis Posted February 1, 2011 Share Posted February 1, 2011 would my assumption be correct? Yup! Link to comment Share on other sites More sharing options...
Unfathomable Posted February 2, 2011 Share Posted February 2, 2011 From my memory of seeing a pair of old peaveys being driven too hard, it generates some "interesting" lighting effects! Link to comment Share on other sites More sharing options...
Bryson Posted February 2, 2011 Share Posted February 2, 2011 See also: Bose 802s, which I believe are part of many a DJ's lighting effects kit. Or so I must assume. ;) Link to comment Share on other sites More sharing options...
stevefez Posted February 2, 2011 Share Posted February 2, 2011 I'm fairly sure the RCF Event series have these as well. Link to comment Share on other sites More sharing options...
Jess-- Posted February 2, 2011 Author Share Posted February 2, 2011 Thanks for the confirmation of my suspicions, I doubt the lamp has ever lit up on these since each pair was being driven by a 250w rms amp. these were used for several years on a fairground ride and actually sounded nice (not the usual muddy sound of a fairground) and apart from the grilles being rusty they don't seem to have suffered. Going off topic here...I would be interested in members thoughts about bringing these indoors as a sound system to a small night club, a new venture with a limited budget, would prefer to use what we have already rather than buy a new setup (at least initially) Link to comment Share on other sites More sharing options...
Takeiteasy Posted February 2, 2011 Share Posted February 2, 2011 The lamps inside are to protect the HF driver(s) £0.17 instead of £40.00 + when you blow the HF / lamp Link to comment Share on other sites More sharing options...
TimmyP1955 Posted February 3, 2011 Share Posted February 3, 2011 These are usually automotive lamps, either a tail light bulb or a dome (courtesy) light bulb. The number should be on the base of the bulb. Link to comment Share on other sites More sharing options...
