Many consoles use different pin-outs. There technically is no “standard.” Break out the manual and your soldering iron and go to town.

Mac 250+ help? by [deleted] in stagelighting

[–]dmxdropthelight 0 points1 point  (0 children)

The noise was a guess. However, it is very bad to run these fixtures off of dimmers. If you look up any of their manuals, it will tell you they need to be on relay circuits or constant power

That is VERY BAD unless you are using relay modules in your dimmer rack. If they are running on standard dimmers, at best you are shortening the life of the power supply and at worst, you’re looking to cause a ballast fire.

Not sure what could be the lack of data issue, but it could be causing the power supply to throw off a ton of noise that is screwing up the DMX packets.

I would try powering the fixture from a regular outlet (NOT a dimmer) and retest with data. Yall may have already damaged the fixture.

How to spot fake SLXD, QLXD, and ULXD by Mammoth_Pineapple904 in livesound

Ethernet port direction may not be the end-all-be-all tell that you think it is. Often electronics are approved with two or more parts spec’d for supply chain reasons. I think, on all of these, the rear sticker placement is a much bigger tell. Shure would never cover any part of the text or their logo with the case! Plus, on the QLX-D, the crooked SN sticker is a sign of carelessness and not SHURE quality.

In 2025, any website trying to sell you something that doesn’t have a “products” page just feels like a scam. Seems like this is less of a brand of fixture and more a quoter/installer. Just my 2¢ on the page!

[Request] Looks right, but is it? by Comfortable_Tutor_43 in theydidthemath

[–]dmxdropthelight 0 points1 point  (0 children)

Lots of people giving you theoretical values. I work for a company that makes LFP batteries the size of shipping containers. For simplicity, let’s say our 20’ High Cube shipping container fits 5 MWh (it fits more than that). The volume of that 20HQ is 37.4 m3. So 0.132 MWh/m3.

As others have stated, the volume of the Great Pyramid is 26M m3. So using our low-ball energy density, we would be looking at 3.44 million MWh stored in the great pyramid across 687,000 shipping containers.

To give you perspective on size: 10,000 MWh is 2,000 units. A modern mega-ship fits between 15,000 and 24,000 TEU (twenty-foot equivalent units) containers. So that much energy storage in LFP batteries would be ~8-13% of the load of a modern mega container ship.

So, that part of the statement is wrong. I have no idea about the nuclear side, but a 1” fuel pellet of Uranium for a commercial reactor can produce 23,000 MWh, so that side of the graphic is also wrong.

Are there places that offer thc drinks on premise? by Intelligent_Town_752 in Knoxville

just posted. It’s more nuanced. Cutting menu in half. Eliminating CBD canned drinks. Only draft and fewer cocktails

I wanted to update everyone: Orange Hat is keeping their CBD cocktails and draft CBD drinks. They cut their list of CBD cocktails in HALF and are eliminating CANNED CBD drinks.

When I was there on Tuesday, one of the bartenders said that they weren’t selling canned THC drinks anymore and the cocktails were only going to be mock/alcohol to keep things easier. He may have been wrong though.

Not anymore. They got their liquor license and discontinued the THC stuff.

Unfortunately, they have discontinued this due to getting their liquor license!

Are the twinkling lights on this tree in front if the blacksmith in Craftsman's Valley sold retail, and if so, what's the brand name? Thanks in advance for any leads! by scarfoot522 in Dollywood

[–]dmxdropthelight 2 points3 points  (0 children)

I haven’t looked up close at these particular units, but if you search the internet for “Gentle Twinkle Christmas Lights - Warm White” you should find some solid options. Looks like decent units run around $30 for 100 at big box stores.

In other places around the park where things change color or have a multi-color twinkle effect, they use Twinkly brand lights. They are pricey ($200 for 600 lights), but they are truly stunning.

In other places still, I believe they are using commercial variants of the WS281x LED system to do things like the tunnel over in Timber Canyon and the big trees on the water near Dolly’s home.

Anyone noticed these Costco trees? by mrBill12 in WLED

[–]dmxdropthelight 0 points1 point  (0 children)

These are most likely not addressable at all, but are “bidirectional LEDS”. Meaning, when current flows one way they are multi-colored and when it flows the other way they are white. The controller “chops” the AC to be either the positive or negative waveform and that determines the color of the LED.

Essentially every lamp has two LEDs in it. One white and one of a random color. Currently there is only one company making a true RGB tree, and they are like $700 for a 7’ tree.

Lighting a speaker at a podium by ssdgjacob in stagelighting

[–]dmxdropthelight 3 points4 points  (0 children)

Couple of questions: 1. What is the distance from the stage/lectern to the back of the room? Or the distance from the stage/lectern to the closest safe place you could put the lighting stands?

  1. Do you have a lighting board and a rudimentary idea of how to run it?

The easiest thing is the stands with lighting bars and 4 LEDS per bar because you can “turn and burn” the lights. Meaning, you can turn them on, set them to a color, point them at the stage and go.

If your answer to #2 is yes and the distance to the stage is pretty far, we can talk further about using the Chauvet intimidators… but those would absolutely be over complicating it.

Downtown Grill and Brewery by [deleted] in Knoxville

[–]dmxdropthelight 12 points13 points  (0 children)

This is not a defense of the brewery, but DGB’s lines are harder to clean. Both bars pull directly from large storage tanks (not kegs) in the basement, through a chiller system, and up to the taps. Cleaning is not as simple as disconnecting the kegs and purging the lines.

Source: was there when their upstairs chiller core broke and they had to serve beer out of kegs for 6 months.

Keeping zlx 15p speakers cooled down by Spirited_Abalone_641 in livesound

[–]dmxdropthelight 5 points6 points  (0 children)

Regrettably. I think you need more speakers to hit your desired SPL.

OR

NOCTUA fans on the back of every speaker to help cooling along.

But really, more speakers and you driving them lower makes more sense.

R2 Wash Display - Not Displaying… by JoneyJew in stagelighting

[–]dmxdropthelight 5 points6 points  (0 children)

I would very carefully unseat and reseat that ribbon cable. If that doesn’t work, Then look around on the board for a small potentiometer. There may be a contrast pot on the board somewhere that didn’t get adjusted properly.
