You mean better than a non code compliant load center (that box is only rated for installation), connected by a non-licensed electrician, accepting all the liability of touching the venue box. 

If the venue doesn't have a 240 connection for you then they can't be expecting that level of a system.  You need to scale back and deal with the power that is provided.

IMHO a good powered system is a must have for these smaller venues as they don't want all the cases associated with the amps.  A set of Yamaha DSR112's and JTR 212's is a nice compact system for these types of venues.

Scott -
I can scale back on the amount of gear I take to said venue(s) that donít have the sufficient power required for a larger system.

Granted, the powerlight amps arenít extremely hungry such as AB amps of yesteryear, but I donít want to run into an issue where the venue is asking for more sound and I didnít bring my A rig to the venue.

Some of these events are rather semi-large Portuguese festivals with attendance in upwards of 600-1000 people. So I always try to bring my A rig when I can (or when it calls for it)

My B rig would be 2 - SB600 subs with 2 - KF300 tops.
My C rig would be 2 - JBL EON 518s active subs with 2 ZLX 12p mains.

I'm getting desperate.  I've started building a lighting setup for our band, that's being run from the stage (or on larger gigs, from a lighting person).  Right now, it's made from 12 LED lights on 8 fixtures (leaving room for FX lighting to come).

But I'm fighting a communication issue right now between the FCB1010 (A Behringer MIDI-pedal) and the Chauvet Obey 40 (a lighting controller.  For some reason I can't fathom, the protocol for lights is that the controller accepts only MIDI Note On commands (instead of something sensible like Program Change) to trigger scenes.

I can program the scenes I need on the Obey40. I can progam the FCB1010 to shoot out Note On commands to change scenes. What I CANNOT seem to do is to STOP the FCB1010 from putting out a Note Off command when I take my foot off the pedal! Either that, or get the Obey40 to ignore the Note Off command! The result is that when I step on a pedal, the Obey40 responds with the correct scene. When I take my foot off the pedal, all the lights go out! "Blackout" on the Obey40 is not being called, since the Blackout LED on the Obey40 display is not turned on, but it has the same effect.

Does anyone know what the heck is going on, and how I can fix this?  So far, Behringer and Chauvet have been no help (Chauvet thought "velocity" was the speed of transmission on the MIDI buss!).  It's working, as long as I leave my foot on the pedal, but that of course is very useless on a stage performance.  I've done MIDI programming in the past, and I'm an electronic tech, but this one has me befuddled.  I inhereted most of this, and knew the FCB1010 could output MIDI Note On, so I thought this was possible.  All I wish to do at this time is change scenes; what am I missing?

I used the Obey40 and FCB1010 together until just a few weeks ago and it was excellent.  I am still using the FCB but now with Luminair although I still use it in Midi Note mode.  I have it set so that i press the pedal and it changed to the scene I wanted.  I have not modded the pedal board in any way.  I did not have to hold it down and if I inadvertantly hit the same pedal it did not turn it off.  Unfortunately my FCB is in a trailer and not available to me and honestly I have to research the settings every time I program it.  I like you was a complete MIDI novice when I programmed it last year and it was a challenge at first.

My suspicion is that the statement 'I inherited most of this' is the issue.  I would reset the pedal board to the default settings.  There is a stomp box mode that might be the issue so make sure that is off.  That setting is in the master settings.

I have a cheat sheet PDF saved in my ipad but I do not have my iPad at home either.  I can only confirm at the moment that what you are trying to do is not only possible but it works great.

I am extremely busy the next couple days but if no one posts a solution I will try to post a link to the cheat sheet I use.  Dont give up its a great combo.

Power strips might be something we frown upon, but in the CorpAV world, they're requisite.

Really great info.  Thanks for posting.  I'll respond in the order you posted...

We aren't necesarily set on a lav.  He will be open to any of my suggestions.

I know nothing about lav mics or head-word mics.  I can see how the lav can be problematic with the movement of the head, clothing, a swinging tie, etc. 

What is the trick for placing a lav on a male?

If we went with a head (or ear) worn mike, what are some of the better options out there?
Here is my cut and Paste of what I wrote a while ago about Lav placement.

One other little trick that someone showed me a while ago. When using a lav for reinforcement on a male always try to put the lav on their tie. You want it centered to minimize the movement created distance changes when they move their head. Also have the person look down almost touching their chin to their chest and move the mic slowly up the tie, have them tell you when they can no longer see the mic. You then put the mic at the position it was just before they couldnít see it anymore. Then be sure to dress the cable very neatly, I would usually put a piece of gaffers tape on the back of the tie to keep the wire and mic in place. And for some reason this doesnít apply to women, I find with them I can clip a mic right up at their neck just under their chin and it works just fine.

I use these small, rubber wheel chocks with my Ber B212 monitors when used.

This is from my Amazon purchased list:

I used wheel chocks from Harbor Freight when I was using the 612M's as monitors (I'm using 712's now, no angle issues). The wheel chocks are also great to prop open doors to get in an out of a venue, and keep my trailer from rocking as well. Multi-purpose wonders.

Test and verify your cabling.

What model is your extender rx and tx?

Used my load bank in battle today and ran a really interesting test where I reversed the neutral and ground lines to test the EGCís ability to sink 45 amps of fault current. And I was able to find that it opened up after 1 minute of heating, but then slowly returned to continuity once it cooled down in 5 minutes. You canít get those kinds of results from an impulse test. You need steady state current.

Somewhat OT, but I bypass the power switches in all my power strips.  They start in the truck, but every week, someone asks for one.

Back on topic, to do this properly, it's costly (weather-resistant boxes from OA Windsor, or similar).  But it's worth it, if you plan to stay in business.

Kevin,

My 3 year warranty is almost up, but no problems so far on the five NU4-6000 I bought.

Here's my review from 2015:

Just before the 2015 Christmas holidays I conducted a battery of tests on some old amplifiers and a new Behringer NU4-6000 four channel amplifier. To my surprise, the  NU4-6000 performed as well on low frequencies as on mid/high frequencies, and is capable of near full power sine wave output with all four channels driven to rated output at two ohms, or two bridged mono pairs driving four ohm loads each. The $350 NU4-6000 appears to be within 3 dB of the $5500 Powersoft K10 published rating on sustained (more than 1 second) output.

The NU4-6000 with two bridged mono pairs each driving four ohm loads just below the illumination of the clip/limit light each put out 85.5 volts at 60 Hz (1828 watts), 84.6 volts at 30 Hz (1789 watts), dropping the mains voltage on a 100' 10AWG 120V line from 118.1 volts down to 107.2 volts, drawing 31 amperes.

Using just one bridged mono pair, the amp ran for 40+ seconds before I terminated the test, as the amp was drawing 19.8 amperes, and the "tired" 20 amp mains breaker had popped several times in various tests already. The amp would have put out more power given a full 120 volts, but the test represents  a "real world" situation, we don't generally plug our amplifiers in to an outlet two feet from the mains transformer.

I also tested my old "heavy iron" bass favorite, a Crest CA9. Bridged into a 4 ohm load the CA9 dropped the mains to 99.6 volts, drew 37.8 amps but only put out 80 volts (1600 watts). The NU4-6000 put out more power, and drew only 50% of the power from the mains compared to the CA9, and weighs a small fraction of the "heavy iron".

My back (and bank account) are very pleased with the NU4-6000, after the testing I purchased four units, and was happy to find that Behringer fixed the fan noise problem, turning the fan speed down when the amp is cool.
Thank you Art. Interesting results but how are they 5 hours in? Time will tell. I, like many have been shy of the B word. The x32 made people pay more attention to them and maybe the are coming along. I posted a thing about china amps, kinda to see what i already know, but one of these companies is making these things. I think, hearing it from you, i may get one. The price is so cheap it worries me for real use. I have spares so if one shits out it is not a huge problem. Thank you.

I just used my extended kelvin bridge today in the swamps of Baton Rouge and it worked perfectly. And the measurements with the 75 ft extensions match what it measured without them. I may have a winners here, but I need more verification.
