Donner DMX512 Wireless Controller Dfi DJ 2.4G DMX Wireless 5 Receivers Short Version with Light Dome & 1 Transmitter Stage Lighting Control for LED Stage Disco Party Bar Lighting 6 PCS Black

We are using from 40 m distance and work perfect.

I've had these for a couple of years now paired with Chauvet Show Express. Cuts a lot of time off of our setup and they work great!

Perfect for bands bringing in their own lighting. I haven't had the opportunity to use it live yet, but in my testing, I've hooked it up and it worked without issue.

The button to turn the receiver on/off is in the inside of the device which you need a tool to turn it off. Very odd the black version seems to be an updated model that’s easier to use vs the chrome which is kind of a pain for the same money. Not sure what is going on at Donner. I love their devices but thought the only change is the model color. Not at all...

For my husband who is a DJ. These work great.

Worked GREAT!! Tested system at a venue that I knew from past experience does ALOT of weddings at the same time with TONS of radio traffic. Not a SINGLE glick!! Just worked. Also, made my set up and tear down faster as well. Found out these also NOW come in a battery powered version!! Just order a set of those today!!!! 3/21 update. ..sadly had a glitch. I have 28 receivers and 4 transmitters. EVERYONE that was set to the purple group would not work consistently. Changed the purple grouping to yellow...only to find only HALF of my lights were receiving a single. Red, blue grouping worked flawless but the other 5 groups did not. End up running dmx wires to 3 grouping to get those lights working. Never had issues in pass but SOMETHING just wasn't right this time. From reading suppose to jump codes but that does seem to happen automatically. Was very frustrating at VERY high end wedding I had booked. So....3 stars. I had previously giving 5 star for these.

In Service 12/23/2015. Application: Small mobile theatrical/dance productions.MacBook Pro 15ʻ, Mid 2013; OS X 10.8.5; QLC+ 10.4.1; ultraDMX Micro USB-DMX interface/dongleJust opened and tested - works exactly as advertised. Works at least 30ʻ distance, through two wooden walls (three rooms away). My Airport reception bombed in the same distance, so i had to get back to the work space to write this.Things i didnʻt realize from the amazon product page:1) to set the address group (out of seven) the transmitter and receivers work on, you have to push a recessed button - good design, for preventing inadvertent changes, but you need a pen or something similar to push the button. The LED color on the transmitter and the LED (in the dome) of the receiver indicate the address group; just match the colors of the transmitter and receiver LEDʻs.2) both the transmitter and every receiver must be powered via their individual power adapters (comes w/ each unit). a bit of a pain as you have to have access to AC power; normally not an issue, but if youʻre running it in theatre grid, you need to make sure your adapter is plugged into an appropriate outlet (iʻm assuming that means non-dimmer).Be aware that the instructions are printed in a size 2 or 3 font, so you will probably need a magnifying glass, especially if your eyes are messed up from staring into lights, hahaha.if someone asks, iʻll post them here.

These are literally plug-and-play. Just remember that each transmitter and receiver comes with it's own AC power cable so you don't want to use these for every light. If you're plugging in power cables for every light you may as well plug in a DMX cable. With that in mind, you can use these to put lights anywhere in the room without having to worry about cable length.Here's how I use mine:I bought two transmitters and 5 receivers. One transmitter plugs into my Chauvet 4Bar and a receiver into another 4Bar and I control them both in master/slave mode with the 4Bar's footswitch. I can now separate the lights as far as I want without having to worry about a DMX cable being long enough to connect them. I use my other Donner transmitter on a DMX controller and a transmitter at the beginning of a chain of ADJ Mega Par Profiles used for uplighting. I connect as many lights as I can with 6 foot cables until I reach a point where lights are far away, like on another wall. For those, I start a new chain with a Donner receiver at the beginning. And since I'm running two transmitters to control two different chains, I simply used a paperclip to assign the Donners in my 4Bars to green and the Donners in my uplights and controller to orange. No interference. No latency. Brilliant technology!
