Ben Lawrance Posted March 1, 2007 Share Posted March 1, 2007 Hi All, Just been given the task of supplying a PA to the local school for their annual fundraiser. The pic below is a plan of the school site (To scale, but I don't know the scale yet) The blue line (thanks to MS Paint) indicates where sound needs to be heard. The pink line indicates where the sound is most important, were most people will be. The sound in the pink needs to co-hearant, and be able to cover the area well, which will include about 500 in it. The other blue area is not so important. As long as you can hear the announcments etc, I'm not too bothered. So hearing things off axis is not a problem. The control position will be where the red box is. The area where the control is, is on a hill so getting it up above people's heads shouldn't be a problem for the main area. What I am after from you you lot is advice on how you would start to go about a job like this. http://img473.imageshack.us/img473/922/bohuntsiteplan2smallsy3.th.png CheersBen Link to comment Share on other sites More sharing options...
Chris Beesley Posted March 1, 2007 Share Posted March 1, 2007 Is the PA just for voice or will you need to run music thru it aswell? If you need it for music what levels are you looking for? Link to comment Share on other sites More sharing options...
Ben Lawrance Posted March 1, 2007 Author Share Posted March 1, 2007 The PA is mainly for voice but it will have music through it at times. Not looking to blow peoples faces off, but just enough to be heard over the crowd (as background music) Link to comment Share on other sites More sharing options...
Simon Lewis Posted March 1, 2007 Share Posted March 1, 2007 Ben, Looks like a job for quite a few 100V line re-entrant horns. You may wish to place some standard loudspeakers in the more important area, or simply use some low frequency cabinets to provide some bottom end when music is playing.

Jivemaster Posted March 1, 2007 Share Posted March 1, 2007 Horns on poles, pointing away from the neighbours. Lots of cable. Sort out the power for the control/amps area or go carefully down the big battery route. Link to comment Share on other sites More sharing options...
dbuckley Posted March 1, 2007 Share Posted March 1, 2007 Horns on poles...Yep, but possibly something more polite in the main area as well. The sound in the pink needs to co-hearant ...Nice, two puns in part of one sentence. Link to comment Share on other sites More sharing options...
Chris Hinds Posted March 1, 2007 Share Posted March 1, 2007 I concur with Simon, use a 100v line system with paging horns to cover the blue area, trying to much else isn't particularly practical, especially knowing how schools are with budgets. I've done a quick and dirty "in paint" addition, but using 4 stacks of Martin W8 or similar, a single speaker on a stick and 5 or 6 paging horns... I've drawn rough coverage on and tried to keep speakers mounted on buildings for the horns. You need to be careful with the cable runs too, especially over long distances. http://blogs.warwick.ac.uk/images/cjehinds/2007/03/01/bohuntsiteplan.jpg Regards Chris Link to comment Share on other sites More sharing options...
Ben Lawrance Posted March 2, 2007 Author Share Posted March 2, 2007 Thanks Chris, As it happens, Mike has sold the W8, so it will be "or similar" A few miles of cable is on the shopping list me thinks! Link to comment Share on other sites More sharing options...
Tarqs Posted March 2, 2007 Share Posted March 2, 2007 You might want to give Dave Middleton of Sorted Technical Servces a call 07905 971184 - he has loads of 100v line kit and a purpose built control box - this coupled with some conventional stuff for the main arena could just do the job Link to comment Share on other sites More sharing options...
Furryface Posted March 2, 2007 Share Posted March 2, 2007 I agree this is a combo of Horns on poles and some pro speakers (either stacks or distriubuted on stands). You could give WE Audio a call. They have massive stocks of 100V line stock (and experience of stringing 8-10Km of cables and horns around the Navy base in Portsmouth), a mobile control/commentary unit, plus plenty of top-notch pro-audio stock (Turbosound/Midas/XTA etc). Give Wayne a call on 01608 737226. Hope that helps Link to comment Share on other sites More sharing options...
jamesperrett Posted March 2, 2007 Share Posted March 2, 2007 Ben - It would also be worth talking to the people who run the Carnival as the system that they set up in the Square each year covers a similar sized area to the Bohunt car parks. Cheers James. Link to comment Share on other sites More sharing options...
