I manage a small performing arts center that seats about 500 but has a large stage in a wide, somewhat shallow and decently live / room.  We were built in 2000, and have since upgraded everything but our original PA, which consists of 4 Renkus-Heinz TRC-121s (front and delay), and 2 blown Renkus-Heinz BPS12-1 subs (we supplement with 2 QSC E18SWs on the ground).  We've identified that these speakers are not great, and wanted to save up some considerable funds to upgrade.

A local broadway house recently did an upgrade, and has some Turbosound TQ-440s and TCS-215 subs available, along with all the processing and amps, and professional tuning and design available for a very low cost.  They're offering with a warranty and with tuning provided by their head audio engineer, so I trust that they care that it is working.  It's very attractive to me as it's currently within our budget that's available now, as opposed to waiting a few years to afford something new.  There are additional benefits that include adding a program feed to our dressing rooms and lobby.

I'm trying to get as many opinions as possible on this system.  We do a mix of theatrical, dance/playback, and live music.  Live music is probably our biggest concern.

Thoughts, opinions?

It's interesting to me that people bag on the DRive Rack PA2 based on experience with prior units.  if you use the PA2 it's clearly a substantial move forward from prior units.  I understand harboring ill will towards a series or brand that didn't meet expectations in the past, I have been guilty of it.  However, I would suggest it not only adds nothing to the conversation equivocating current products to old models, it actually makes it more difficult for those seeking actual knowledge.  Many companies and products improve over time i.e. Honda or behringer or a myriad of other examples.  I have owned three generations of Civics and the evolution is startling.

I personally use a PA2 and love it on my rig comprised of X32, EV QRX and QSC.  Its not a high end rig but it has met all of my expectations and then some. The PA2 one of my favorite pieces and i highly recommend it.

Agree and not harboring old bad will.  Had two PA2's sold them within a month of buying them.  I also have a new Venue 360 and it's down in my home theater where I can manage the gain structure. 

I don't know if it's a word size issue or what is going on but if you underdrive them you lose dynamic range and your mix ends up what seems like the noise floor.  Hit them too hard and they just wack the dynamic range off the top.

I rarely speak bad about products but in this case I have broad experience across both product lines.  The older 260's, and 4800's were excellent.  That's why used 260's are going for more than new Venue 360's

Thanks Stephen for the response.

 For clarity, my original concern was that I would have potentially two paths to ground, one being the known ground of the connection between the ground screw on the generator and the copper bond between my AC and pool pump, and the potential ground of the security chain wrapped around the metal handle of the generator and the other end of the security chain wrapped around an aluminum fence. I was not sure if having two paths to ground, if the aluminum fence is grounded, was unsafe.


To this specific question.  The NEC requires any and all "grounding electrodes" present on a premises to be bonded (connected with a metalic path).  Obviously, if multiple paths to ground were an issue that would not be required.  It is common to have ground rods, metal water lines, gas lines and ufer (concrete encased electrodes-usually the rebar of a foundation) all connected in building.  I just finished a large inustrial addition with a separate service than the original building-both steel frame buildings.  For safety purposes we intentionally bonded the frames of both buildings.  There are a LOT of paths to ground in this structure.

In addition, code requires anything metallic that "may" become energized to be bonded to that system-ie a fence that has a power cord run through, over, or near it.

Guys service hi tension lines while energized by wearing a metallic "farady" cage style suite.  The idea is that in a suit like that no part of their body can be energized to a different part than any other.  That is the same idea as bonding metal parts and grounding electrodes (either intentional or incidental) together to create one big metal "cage" of anything metal on a premises.  Your concern of the chain wrapped around the fence and genny without an intentional bond is a perfect example of hazards people often overlook-you were wise to see that as a hazard-I would suggest ensuring that is in fact bonded somehow.

Others have spoken correctly on the ground-neutral bond.  This specific connection should exist for safety-and it should exist in only one place.  Multiple G-N bonds will create undesired, unsafe loops.

This comment only applies to using the generator stand alone.

If using the generator with the quad box you linked to, the security chain to the fence will be fine. The ground wire from the pool will be the safety ground.

However, to make faults to ground trip the circuit breaker, you need to bond the neutral to ground. The easy way, as described by Mike Sokol, is to take a common Nema 5-15 cord cap, wire the neutral screw to the ground screw, paint it an awful color, and plug it into a receptacle on the generator.

Note, the shorting plug should not be used when connecting to a home breaker panel as the main panel will (should?) have bonded the neutral to the ground (per NEC) and you only want that bonding done in one place.

I have a TMB Proplex from Mike Pyle that I use with my GLD80 to either a AR2412 or a AB168. I got a 100' model and if I were doing it again I would get 150'.
Initially it was a bit stiff but by the time I got 4 or 5 gigs on it, it loosened up and made for easy over/under coiling.

I would buy it again.

Unless I missed it, the OP hasn't said what the audio goals are.

Dance can mean many things. Does he need it loud? How loud? How about low? EDM levels? Big thump... or not?

Lots of suggestions but how do we know what he needs?

There is "dancing" at EDM events?  I thought the dancing consisted mostly of bodily movement inspired by consuming MDMA and other "experience-enhancing" stimulants and hallucinogenics.

That said, you're right, Rob.  We don't know enough at the SPL and bandwidth needs to make specific equipment recommendations and we're also not particularly aware of what products (and at what prices) are available in Markos's part of the Mediterranean.

In another post someone mentioned they would give up a career full of gigs for one night with Earl Scruggs.  That got me to thinking, who would I really like to mix.


-SRV at any point
-Dave Matthews Band in the 'Ant's Marching' years
-Joe Bonamassa today

Jeff is one of the 'good guys' in the speaker biz.  Customer service and support are top notch and Jeff is a genuinely friendly and knowledgeable designer.  I'm not at all surprised that you had a great experience working with JTR.

I'm particularly interested in how your rig will work in theatre, where pattern control is critical and articulation is essential.  I suspect the latter will be no issue but there is a limit to pattern control based on the physical size and form factor (and hence, frequency).  Looking forward to your impressions as you do more shows with your new rig.

ps:  don't sell off your Altecs cheap...

Captivator 212pro has been measured by Data-Bass:
http://data-bass.com/data?page=system&id=142

The CEA2010 measurements are 2 meter, rms so add +9db for 1 meter, peak.
The longterm measurements are 2 meter so add +6db.
The Captivator 212pro had a 6-8db advantage over the BC 21SW152 in the musical range (above 45hz).


I want to say the is not a review. I haven't been able to use the 212s as much as I would like to have at this point because of an ongoing house gig and the fact that I am just a weekend warrior. But, I will say I am really blown away with the performance and musicality (may or may not be the best word) of these little beast. But my second favorite part has been the form factor. I can easily stack four in one spot on my 12' "V" nose trailer leaving room for everything for sound, including 3 light stand/bars and still have a clear floor to walk into the trailer. At only 16" tall it gives me a lot of flexibility with setup. I can place them in the center front of the band in all kinds of scenarios. And the price is insanely inexpensive for the build quality. Just can't say enough good things.
