I am on it..Thank you David.. By the way its Tijo. not Tojo.. :)



Tojo,
I really suggest you get some training on Dante.

https://www.audinate.com/resources/training-and-tutorials

And here

http://www.yamahaproaudio.com/global/en/products/mixers/cl/selftraining.jsp

Will be good starts for you. Specifically anything on the Yamaha site related to Dante.

...I was referring to using the manufacturer supplied ground screw on the generator connected to a copper ground wire that runs between my pool pump and AC. I was not planning on making any type of internal modification or ground to neutral adapter.

 My original plan was to output the 30 amp/125volt, twist lock receptacle on the generator, connecting a 100 foot, 10/3, GenTran cord with a quad box. Each duplex on the quad box has its own 20 amp breaker...

Steve,

Kudos for asking questions. You've inadvertently stepped into a tricky world. Floating neutrals are 'magically' safe, and code compliant for their two most common use cases for Joe public:

1. "Cord and plug connected" equipment (e.g. power tools, emergency refrigerator) with no connection to earth. This is safe because there is no fault current path, and is code compliant as per NEC 250.34.

2. Tied to a house panel via transfer switch for backup power. Here the panel provides the neutral -> ground bond, and the floating neutral insures that there aren't two parallel paths to the generator over neutral and EGC, as required by NEC 250.6.

As Stephen has explained, many points of bonding between ground rods and GEC is common, preferred, and to code. Ground to ground is good.

The problem arises when there are multiple neutral -> ground bond points, which can cause the EGC, which is normally not a current carrying conductor, to be a parallel path for the return current to the generator.

Quote
I am still a bit unclear if I ground the floating neutral inverter generator using the ground screw connected to a copper ground is unsafe.

If you are going to bond the generator to your pool GEC, and then use outlets connected via cord and plug, you should create a N -> G bond on the generator in the manner that Rob describes in this thread.

If you are going to use the Yamaha with a transfer switch, then the N -> G bond will be in the panel and the generator is ready to go without any additional bonding.

If rider acceptability is not a concern, I say - Do it.
These boxes were designed when Turbosound was at it's peak.  They borrow heavily from the larger the Flash/Flood boxes.  We have a half dozen of the TQ445/425 systems which is essentially what you are looking at with minor tweaks. IMHO it would be an excellent choice for the room you describe.  These were full on high end pro boxes built for the most demanding applications.  They sound excellent.  Vocal articulation is very good and natural.  They will get VERY loud if required. This system excels at live music reproduction.  The response at the edge of their horizontal pattern perhaps is not as smooth as some newer very expensive point source boxes.  They require a little fiddling in their horizontal placement if you are going to use multiple boxes in a cluster.  This is a "feature" of every speaker system from this era and is hardly a deal breaker.  Careful aiming of the install (especially inside where reflections will come into play) should minimize the interaction to the point where it is pretty much a non issue.

We have 7 different speaker systems in our warehouse to choose from.  If we are doing a small 500 peep show the TQ445/425 remains our favorite system to use.

To summarize, you can buy a complete Turbo TQ440/TCS215 system with speakers, amps and processors that has been installed and successfully used in a Broadway theater.  The seller will provide their head audio engineer to design and tune the installation for your room.  The seller will warranty the system/installation.  Their price allows you to go forward with this plan today......

Sounds like a really good plan to me.
Best of luck.

Thanks Steve, that's exactly what I was thinking, but wanted to see if anyone has a reason we shouldn't do it.

In our venue, we're working with acts that are not terribly picky about equipment details, as we're looking at smaller acts.  Most we've had state that our current system is better than most (which is a bit sad).

Doesn't that almost describe this particular speaker even when used as intended?   :P
The OP wasn't actually talking specifically about VRX; he simply used that as the closest similarity to the design of speaker he wanted to build. Riley's comments, therefore, were directed specifically at the intended deployment that the OP was suggesting.

A bunch of BS & drama later, and several story changes, the OP got upset and left.

That happens with ANY loudspeaker(s) that have drivers arriving at the listeners ears at more than 1/4 wavelength apart in time.

That is why it is important to use a single source of sound, or if you use multiple cabinets, use cabinets that have large enough mouths so that they have real pattern control so the levels from the different cabinets are very different, so they don't interfere with each other.

Small horns-or narrow horns that are not LARGE, simple do NOT provide this needed pattern control

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?

AC/DC would be a lot of fun.

First time I saw them in person was a concert all in Tokyo Japan.  Buddy of mine got "front row" tickets - literally standing in front of the stage barrier.....and 5 ft away from their massive row of subs.  Practically had to get folks to write messages as my hearing just disappeared for several weeks....and that's with using ear plugs....but it WAS fun!

I'm NOT an Eagle Scout.  Scout Program disbanded in my neighborhood after 2 years.  Only spent time as Cub.  But my son IS an Eagle Scout.  Earned it last year.  Made up for it though.  fast foward 50 years and today, I'm a Merit Badge Counselor, Unit Commissioner, OA Brotherhood, Distinquished Scouting Award recipient and current District Chairman in NYC area.  Lots of fun in the "spare time".  Philmont, Seabase, Northern Tier, Ten Mile River (for those in the NorthEast)....love those "bug nights" out in the open under the skies.

I've also had some success with the Microphone Madness headsets.
http://www.microphonemadness.com/mm-dual-ear-psm-pro-series-dual-earset-microphone.html
They claim "As good as the Countryman E6 or your money back".
I did get a mailshot this week saying buy 5, get one free, but I can't see a reference to it on their site.
Also not sure if you can buy them over there, but i've recently been using the JAG (Just Audio Gear) headsets and they've been brilliant.
