sarah.w Posted May 10, 2015 Posted May 10, 2015 Hi. I wasn't sure whether to post this in beginners or sound so please move it if I chose wrongly! I work for a charity which sometimes puts on fairly large functions in a local venue. We've been donated a couple of speakers to use to help us out as with our numbers increasing (250+) someone on the stage speaking isn't really audible! The speakers are Celestion SR3 MK2 8 ohm. There's 2 of them. We were also given another box which says it is a Celestion SRC3 loudspeaker control system. I don't really know what that's for! As you have probably guessed I'm not particularly technician so I'd be very grateful for some assistance from you guys. I need to know what kind of amplifier and cables to buy for these speakers. We'd be using them for voice as well as music. I have someone who can loan us a microphone and mixing desk if we need it but he doesn't have a suitable amp apparently. Any help/advice would be greatly appreciated :) Sorry, forgot to add, obviously as we're a charity a small price tag would be ideal. Second hand is fine I just don't know what I'm looking for!
Peter18 Posted May 10, 2015 Posted May 10, 2015 Hi Sarah, I own a similar set of SR3 speakers which enjoyed a previous life as the PA system for a small folk band. They were quite well regarded speakers in their day (about 20 years ago?) and are capable of a respectable sound especially on voice. The SRC unit is the 'speaker controller' and is important to adjust the relative loudness of the top and bottom of the frequency range (a bit like the loudness contour control on some hifi systems).The connection seqence would be mic into mixer into speaker controller into amplifier into speakers. A suitable amplifier would be rated at about 200 watts per channel (rated into 8 ohms). You would need cables to connect the mixer output to the speaker controller and from the controller to the amplifier. The controller uses standard mono jacks. You would also need speaker cables to connect from the amplifier to the speakers, these would probably have speakon connectors. Do not forget that you will also need a pair of speaker stands to support them (they are too small to work well placed on the floor).To be honest it will not be the lightest set up to transport around and better lighter systems are readily available. Once you have priced up the cost of the amplifier, cables and stands you may find that for the same budget 'active speakers' from such suppliers as Thomann are available. These you could simply plug a mic directly in to for the simplest of setups. Send me a PM if you would like some more specific suggestions.
richardash1981 Posted May 10, 2015 Posted May 10, 2015 A suitable amplifier would be rated at about 200 watts per channel (rated into 8 ohms). Just as a warning, a stereo amplifier capable of 200 watts per channel will usually be advertised as a '800W amp', because the advertised number will be the sum of the two outputs, and into 4 ohm loads, where amps generally produce twice as much power as into 8 ohms (what most speakers are). You can probably obtain a suitably sized amplifier second hand by trawling through ebay (but it will be tedious tracking down specs to check it will do what you want), and the amplifier won't be light, even if you go for a fan cooled one (on which the fans may well need changing). This supports the suggestion that a budget active speaker from a reputable supplier may be an easier solution to your problem.
