Hi folks,
I have an opportunity to act as house engineer at a new club opening here... Before I came along, the owner had already installed a large PA that consists of a combination of stuff he'd brought in and some gear that came with the room...
The room is about 65' wide and 110' long, with ~20' clear to ~4' of duct work, lighting and steel truss ceiling. No treatment as of yet. There is a stage about 3' high and ~20'x12' centered at one end, facing a long bar at the far end. There is a dance floor that's stage width and ~30' long...
I took a day inventorying everything; opening up cabs to check drivers and testing it out then, another day on Google getting the specs on what I could.
The owner wants to split the PA use between house/guest DJ's on weekends and bands, every couple of weeks. I am posting the system below and requesting constructive comments/opinions/advice on improvements/configuration, etc. So, without further ado...
Speakers:Mid/Highs:- 4 bi-amp cabs (custom built by "Woods", whoever they are...)
They have a 90 deg. horn w/Emilar EC320a 8ohm comp. driver and a ????? 12" mid driver
- 4 Transparence TR15H2
http://www.tr.ca/2006/english/products/enclosures/th-15h2.ht m
Which are 8ohms and rated 700w rms
That's it for tops. They are currently flown ~15' high pointing down around the dance floor. Only one pair of the 'Woods' cabs, flown on either side of the stage, face down room. We can (and likely will) move some of these...
Subs: (holy cow!)
- 4 Cerwin Vega B36-A 18" horn loaded w/orig. drivers, ~10yrs. old
- 6 18" K151 'W' bins, loaded with JBL 2240H (600w prog.)
- 2 smaller 15" 'W' bins, loaded with JBL E140-8 (400w prog.)
- 6 unknown make, dual 15" (horizontally mounted, vented reflex. They look like these:
http://www.tr.ca/2006/english/products/enclosures/nac-215.ht m but there's no badge...)
These are placed as follows:
-the 3 18" W bins and 1 15" W bin are stacked on either side of the stage.
-the 6 dual 15" cabs are lined up side-by-each and built into a platform butted against the front of the stage
-the 4 CV B36's are lined up in a row and built into a dance platform at the 'down-room' end of the dance floor and FACING the stage. Thus, demarcating the dance floor area...
All of this is powered by:
Power Amps:-QSC EX4000 on 3 18" 'W' bins/ch. Therefore, only ~500w/cab
-QSC EX4000 on 2 cerwin vega B36A 18"/ch. Therefore, only ~600w/cab
-QSC MX1500 on 'Woods' high freq. 2/ch. Therefore, ~300w/driver
-QSC MX1500 on 'Woods' mid freq. 2/ch. Therefore, ~300w/driver
-Audiopro MOS 500 - on one 15" JBL 'W' bin/ch. It is 250w/ch. into 4 ohms. Therefore, well less than that on these 8 ohm cabs...
-Crest CA12 on 3 dual 15" subs/ch. Don't see how this even works, unless the cabs are an 8 ohm version, in which case, only ~500w/cab, for a sub (assuming it's the one linked) rated at 1500w rms...
-Behringer EP2500 on 2 Transparance tr15h2/ch. Therefore, only ~325w/cab
All of this has only a Furman X-424 crossover in 3-way mode and an Ultragraph Pro dual 31 band EQ for processing...
So, I'm going to refrain from commenting, or sharing my opinion for now, as I'd like to use this thread to provide the owner with an unbiased critique of this system. Then, based on your input, I hope to discuss some ideas with you guys, so I can begin the process of getting the most out of this system...
Also, there's been some discussion about selling part (or all) of this stuff and starting from scratch. So, feel free to suggest upgrades, reconfiguations, etc.
TIA
