Revelationroadshow 0 Posted November 20, 2007 Report Share Posted November 20, 2007 (edited) Talk about closing the stable after the horse.... Just been booked to do a Christmas party in the Grand Hall at Ipswich Corn Exchange. First question - has anyone already worked there and can I have some advice! Still trying to get some definative info about the venue, but am told it's a high ceiling venue with auditorium seated capacit of 1400 and banquet capacity of 400. Guess I hust want to be reasured that my rig will cope, or give myself enough time to panic an scrounge more! currently I will have a pair of 400 watt Mackie's (probably SRM450's) and my Mach subs - about 500 watt each. That I think gives me about 1.8K. Does that sound like enough? If not, would I be better bringing in a bigger PA, or adding extra speakers to place around the dance floor? (and I would assume I'me best with actives or run of seperate amps?). As for lighting - currently is's two miniMAC's, 3 datamoons and we are putting our LED uplighting system around the room - that sound like underkill A little more information..... Room is 27.4m x 17m with a purpose built stage area. It's also got a high roof! Booked in to go and see it next Tuesday.

DJ Marky Marc 0 Posted November 20, 2007 Report Share Posted November 20, 2007 Depends on the affect you want to have.. if they are expecting a full on party night club style then your going to need more sound.. if its just a posh dinner dance with not many people taking to the the dance floor then you have enough sound for the dance floor area.. im doing a few gigs this xmas for arround 500 people a night and using about 4 or 5 kw of sound for the dance floor and extra lighting to theme the venue... the short of it is if it was me i would get some more sound in... <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
TonyB 0 Posted November 20, 2007 Report Share Posted November 20, 2007 Hate to worry you Matt but you obviously haven't seen the size of the place. I think the setup you mentioned will sound like a tranny radio in the Albert Hall. I went to a gig there a couple of years ago and the ceilings are very high. http://universalpa.co.uk/I/ipswich-corn-exchange.jpg Link to post Share on other sites

Revelationroadshow 0 Posted November 20, 2007 Author Report Share Posted November 20, 2007 quinny hasnt got 6k :ads: So what has he got? He says he has your old JBL rig and is running it from 4 amps..... Surely that will be big enough? <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
FrankieJ 0 Posted November 21, 2007 Report Share Posted November 21, 2007 I agree with Mark, if they just want the sound on the dance floor area than you may just get by. DJ Frankie Knuckles. Link to post Share on other sites
DJ Marky Marc 0 Posted November 21, 2007 Report Share Posted November 21, 2007 quniney has a pair of 2Kw amps... so with all the taps open thats 4000w of sound or 2kw of top and 2kw of bass.. <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites

I think you'll find he has four 2Kw amps now (I know, I keep telling him off for spending money rather than making money), so with the "taps" fully open, I make that 8000w of sound. Although I have done my maths. bridged mono, his amps will push 2500w each. The JBL's are rated 500 RMS, so won't he fry them with the "taps" fully open? <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
norty303 0 Posted November 21, 2007 Report Share Posted November 21, 2007 (edited) I'm assuming that this JBL rig is 2 stacks (2 tops, 2 subs) In my opinion, if it is required to do the whole room and not just a focussed area on a dancefloor then imo you simply don't have enough speakers to get the coverage. If you look on the picture you can see that they have 2 mid tops per side. you'll need this to cover the centre and project towards the rear of the room. The difference between 6k and 4k of amps will be minimal in terms of output when spread over just 4 cabs. Adding 8 more cabs on the same amps would have more effect. 8000w of sound There is no such thing. if they are expecting a full on party night club style then your going to need more sound.. LOTS more sound.... Edited November 21, 2007 by norty303 DIY plans and pro audio related technical discussions www.speakerplans.com/forum Link to post Share on other sites
Andy Westcott 0 Posted November 22, 2007 Report Share Posted November 22, 2007 Just an observation: Quote: "8000w of sound" Norty's reply: "There is no such thing." There is, actually. It is theoretically possible to produce sound at a power level of 8000 watts, but it would be rather loud, and probably fatal to anything within a few hundred yards of the source! (Okay, I know what you mean really - just being awkward for the sake of it!) For the sake of those not in the know, the actual power contained in radiated music is a tiny fraction of the electrical power fed to the speakers - speakers are extremely inneficient, most of the power being turned to heat in the motor itself. It would be nice to fill the venue illustrated above using just a 10 watt amplifier, but we need to develop our transducers a bit more yet! Link to post Share on other sites
rictic 0 Posted November 22, 2007 Report Share Posted November 22, 2007 how many watts needed i believe was the question. well after seeing the pics of the venue i woulda said what.........what..........what.........( 10,000 times)............have i let myself in for????????????? but really what a nice room to gig in. hope you get your sound sorted ok bro. maybe the right cabs with the right dispersion pattern will perform better than just just sheer volume, but only a guess. dont wanna be filling that ceiling void up with sound that could be directed towards the guests. <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites

Revelationroadshow 0 Posted December 7, 2007 Author Report Share Posted December 7, 2007 (edited) Well thanks for the help. It's all over now.... AND IT ROCKED!!!! Had the wonderful Quinney to help - I still have a headache from his JBL's (although I think in the end my Mackies would have handled it). The folk at Powergen were glued to the dance floor with a collection of mainly 80's tunes - went mad for 9-5 which has never happened to me before. Quinney- all I'm going to say is "My My My"! Had a great techy from the venue on hand when we arrive who did a lot of lugging of gear - shame he didn't want to at the end - small lift, 2 hour pack down! Still the remote control helicopter looked like fun! First paid for outing for the venue paint system (thank to Mo for help there) - looked great and at the point that one of the guests managed to completely remove the DMX cable from the DMX plug (while leaving the plug in the LED PAR), everyone was far to drunk to notice! Once I work out how to, I'll pop some pictures up!

yourweddingdisco 0 Posted December 11, 2007 Report Share Posted December 11, 2007 Glad to hear it went well Matt...........although we both know you charged Waaaaaaaaayyyyyyyyyy to little for it. That should of easily been worth £800-1200 for that! Link to post Share on other sites
