Great video JR. You provide some seriously good " real experience " advice... As an Electrician over 34 years, ALWAYS use a tester on the recepticals! The two most common problems are no equipment ground, and reversed polarity. ie, the hot and neutral are reversed. If you test and find no ground, please do not use that receptical. This is really dangerous and could easily be an electrocution hazard. Any exposed metal parts of any of the equipment being used must have the same potential. In other words, all exposed metal parts are electrically equal. If you can, check out the venue before the gig. You may have to rent a generator. On a side note, back in the day, instrument amps had a polarity/power switch . What this switch did was reversed the power polarity to eliminate humming. I can't tell you how many times a guitar player would touch their lips to the mic and get shocked. Why, because the metal mic was a different polarity than the metal parts of the guitar. I kid you not...
I remember helping my friend in the 90’s with the sound. With each kick, the street lights around the neighborhood would flicker at an open air venue. Things have drastically improved around here since then.
Thanks man, just moved my Sub to a separate outlet in parallel with my monitors rather than series and it fixed my problem. Kept hearing popping from my monitors and tweeters making cricket noises. I thought I just had a bad JBL sub because the audio cables run through the sub but it was the power source and I almost bought a power conditioner to fix it, but that did it.👍
My old roommate went to India with his dad to shoot a documentary, they no shite had a bamboo pole with a copper wire run up the middle, with a hook on the end, and they would hang that on the power line for the lights..........lol
Thanks for the episode! It was me! I saw the spider box in another video and requested the Power topic! You blew my mind with the power conditioner bit, I have Monster Cable power conditioners in all of my amp racks! But all my amps are Class-D minus my QSC RMX 2450
Just did a quick snippet on a video about power. It is frustrating when folks don't understand what power requirements are. Brand new venue, which is very nice, and the folks that built it were there and came to me and asked me what needs to be done better....first thing i said was power. I suggested 6-20 amp circuits at the stage. You mentioned having 450+ feet of cable....another issue I see a lot is enough power, but its 300ft away. That makes a huge difference. Love your vids and info bro, keep it coming!
Yeah I should probably clarify that I carry that to run multiple lines no more than 100ft away. Anything over that at 12gauge and you start losing power. Great point brother! Thanx for keeping me honest. 🤘🏻🤘🏻
On a side note if you are getting fire extinguishers make sure it's rated for the type of fires you are expecting. For electrical Ideally CO2 & not a powder/water/foam. A CO2 unit won't trash your equipment.
I spent a few thousand on voltage regulators, that's not the same as a power conditioner. It keeps everything at 120v all show. It has backup battery in them and very fast capacitors . No brown outs.
Quad boxes with an Edison tail is what I hand make to string some together upstage and downstage. Quad boxes have four, while triple tap has only three. Quad boxes win in my book.
I have a small live sound rig. 2 JBL SRX 700 dual 15’s. 2 JBL PRX 800 subs SRX’s r powered with QSC RMX 1450 1 amp per side. Subs have a QSC 3000A. Everything is bridged. Monitors have 2 QSC RMX 850 and I also have a QSC PLX 3002 as a spare. Would you put the 2 1450’s on the same circuit? I currently have them running through power conditioners 🫣
The rmx1450 pulls 6amps at 4ohms so you could run two off the same circuit especially on monitors. www.qsc.com/resource-files/productresources/amp/rmxa/q_amp_rmxa_currentdraw.pdf

Great video. I love when they look at my like I have two heads when I ask them not to plug in all of their amps on my sound electric.
My old roommate went to India with his dad to shoot a documentary, they no shite had a bamboo pole with a copper wire run up the middle, with a hook on the end, and they would hang that on the power line for the lights..........lol
Love the crown amps!

Class D still needs to be plugged directly into the wall. All mine are class D as well.

lol. 3 is better than 4, but the triple taps pack up easier and don’t pull apart as easily. Just my .02. You do you boo… 🤘🏻🤘🏻

do you use ground fault receptacles on your extension cords? I was thinking about going that way for liability reasons.
I do on the break out spider boxes but not usually. GFI’s are typically a pain especially if they have some age on them.
So is it good to plug the main mixing console into a 15A power conditioner? Should we not use 15A power conditioners in live sound at all??
No just the amplifiers. Use them on everything else.
@@thegrumpysoundguy Ok thanks 😎
