RioRand DMX Splitter Amplifier,8 Channel 3Pin 1 Input 8 Output Opto Isolated DMX512 Signal Distributor for Stage Lights,Moving Heads & DMX Controllers

Works great. I use it for DMX on my second DMX universe. I only wish it has an out line to daisy chain it to another box.

Just got two of these and they work perfectly. Checked the insides and they are optically isolated on each of the 8 outputs, as they should be. But the case is plastic and I doubt this would survive as a road show unit unless embedded inside a sturdy case. Ours are permanently installed so there should be no physical damage. Other than the case, which is of no concern to my installation, I think this is a product of choice as opposed to the $150 units which are built to handle physical abuse. Ours run at the end of 275 feet of cable from the console and there has been no issues with reliability. Man, I love it when I get a great price on something that works!!!

The device feels like what you would expect for the price point, but it works great and does what it claims. Some of the other options in the $50-$70 range claim to be optically isolated but are not. The seller is definitely listening to feedback, as mine included a power adapter, as well as the bare wire lead, and this one has a status light/signal indicator. Unless you want to get one of the $300+ units, this is really the best option.

== UPDATE == After working with the seller, I received a new unit that does work. Overall unit is basically 3 stars, but I gave it an extra star for the excellent support that I received from the seller. Summary: *Very* cheap, but does work as a basic DMX distribution amplifier. I purchased this DMX amplifier because I needed an inexpensive DMX D/A to send along with our bands lighting system. We don't have a lot of money, and our requirements for DMX signaling are very minimal. The issue we were running into at a lot of venues was that we just had too many lights and occasionally the run distance was too long for the USB powered DMX King USB to DMX adapter to drive effectively. I connected the RioRand amplifier directly to the USB to DMX adapter and ran the lights without issue. We typically run 10 no-name LED Par lights that I purchased elsewhere on the internet for next to nothing. The distance from the controller usually ranges from 15 feet to 25 feet depending on the venue. Since most (all) super-cheap LED lights are simply passing the signal along with no isolation and don't re-drive their output, you need to start with a pretty strong signal. This unit allowed all of my lights to work without issue. Build quality: I can't finish this review without discussing the build quality of the unit. The unit itself is made out of a sturdy plastic that should be pretty resistant to most bumps and rough treatment while on the road. HOWEVER: The internals of the unit are a different story. The insides of this unit are not actually attached to anything. When I received this unit, there was some obvious rattling internally when shaking the unit. I took the unit apart to discover that inside is just a single PCB with the wires to the individual jacks. While this isn't a problem in and of itself, the PCB isn't actually attached to anything inside the box. It just kind of "floats" inside held only by the wires that connect it to the external jacks. This probably explains the rattling noise when the unit is shook. I took some peel-and-stick cable-tie anchors and cable ties and attached the PCB to the bottom of the enclosure. It's not perfect, but it should prevent the unit from coming apart internally due to a bumpy ride or a hard jolt. Overall, for the cost the unit performed well in my first few uses, so I can't complain too much. If you need a dirt cheap DMX D/A, this will probably work for you. If you have expensive lighting and require a road-ready DMX distribution amplifier, you might want to look elsewhere. == ORIGINAL REVIEW == 1st one I received didn't work. Waiting on 2nd unit to come in. I'll update my review if the 2nd one works any better.

RioRand DMX512 Signal Splitter Amplifier (3-Pin, 1 Input / 8 Channel) has been a solid addition so far. I haven’t fully tested it yet, but initial impressions are good. Build quality feels solid and the terminals plug in firm with no looseness. I was also able to mount it permanently on the ceiling, keeping everything hidden and clean for my custom patio lighting setup. Once everything is fully up and running, I’ll update with photos and a more in-depth review.

Tried this splitter several times with different fixtures. Lights would blink and not respond right. This is either a bad splitter or just junk I hooked up a quality splitter (more expensive) and the lights work fine.
