- This video shows the construction of a 4U, 24ch mic splitter panel for an in ear monitor rig I am building. The project shows the custom hinged metal panel, loading the panel with XLR connectors and soldering the tails.

Lovely. Hey, what lacing strip are you using for strain relief? I've seen it on Entertainment Metals panels but I've been looking for a direct source. Do you happen to know one?
Something I like to do in the extra-mile category is to use a clear color coding ring and label the cable with a piece of paper inside it. It takes a little doing to get the template right, but it's well worth it!
Sure! That's great! We use a heat shrink tube with the channel number spelled in both name and numeral. I try to include loose clear heat shrink whenever possible so customers can apply their own labels.
cool diy project, thanks
Could you answer me a question? What is the specification of the cable you used?
I didn't see anything about using transformers to maintain the voltage after splitting, Seems to me like you don't mind that, but do you plan to add it later on? All mic splitters i''ve seen, have to pass through a transformer. I am still looking for a good affordable one.
Good transformers aren’t affordable.
Nice pro work. I like your hinged panel. QUESTION - I am considering a smaller 24ch passive splitter panel using 24 xlr females and 3 db25 wired in tascam audio standard pin out to provide the 24 channel feed to FOH on three 8 channel snakes db25 to xlr male. The inputs to my x32 rack will be hard wired from back of panel and live in my iem rack. Do you have a metal fabricator that could build this 3 u panel?
Hey Mark, I can do it for you. Just shoot me an email: billy@lmcases.com
Whats an in ear monitor for?
Beast
Billy have made patch using 1x2 aes connections? Do you run into issues with gear using it? I hope I ask this question right.
It’s simply a female xlr on one side >> to 2 male xlr on the other, right?
it's look nice, where you can buy these panel? i want to make the same 2 times..

As far as Phantom power goes... wich console gives the 48V? FOH or monitor with a splitter like this?
FOH. Though in this config, either console could provide it.
@@billylaguardia But will that not harm the other console?
@@kasperlassen2396 Nope. Though only one console should provide phantom. Generally the monitor console provides phantom. Larger mic splits for touring are generally just larger versions of this panel with pin 1 ground lifts per channel. Despite the ubiquity of low cost 8 channel transformer isolated mic splits available, most splitters are not transformer isolated. OB trucks usually want transformers since they are often the 3rd or 4th split in larger shows. They also have longer cable runs to deal with. Hope this helps!
Really really clean and nice job)) but… is there any signal/voltage loss in this kind of splitter?
yes. The voltage has a separate path to go down, so it most certainly will have some loss. Kirchhoff's Voltage Law. Also, I would use the copper ground and the shield to chassis. They perform different functions in grounding and signal loss. It would be different if they were twisted pair, but they are not.
@@TheDivergentDrummer I am a retired electrical engineer. Contrary to a common first intuition (once mine also) the shield and drain wire should always both be connected ONLY to pin 1, never to the chassis/shell tab. I have been doing live sound and installing/troubleshooting systems for 57 years, and I have seen some really crazy noise problems that were caused by doing what you suggest, combined with other electrical connections to the same chassis, and related to ground loops. Don't do it.
It’s negligible. This style of passive splitter is very common.
Boa noite Billy, daria para usar esse mesmo projeto para mandar o mesmo sinal de áudio para duas mesas distintas ?
sim
Why don't you use all the colours on the boots? - 1 Brown, 2 Red, 3 Orange, 4 Yellow, 5 Green, 6 Blue, 7, Violet, 8 Grey, 9 White, 10 Black with a Brown ring, 11 Brown with a Brown ring, 12 Red with a Brown ring etc, 21 Brown with a Red ring etc. 32 Orange with Red ring etc.That way you don't have to go searching through the numbered labels. Colloured Neutrik rings are part number: XXR-*. Replace the * with the relevant colour number.
Can you explain when you need a splitter with transformers vs when you don't. Context I'm building an in-ear system.
Hey Dennis, this is an excellent question that will probably end up being a video. The quick answer is that you don't really need an iso transformer in a 1:2 XLR split since all the signal sources are balanced. Mic splits use a unity 1:1 transformer meaning they don't change or alter the signal, just pass it through. Jensen as an example makes a dedicated mic split transformer. This allows manufacturers to use the transformer on a PCB to make the "split" vs soldering multiple cables on a solder lug of a connector. They just take a winding off the transformer that is the duplicated audio signal. The benefits of a transformer are RF rejection and you are electrically isolated (hence the clever name) from anyone else (say FOH or Mons) sharing the original signal. I generally don't spec a transformer on 1:2 splits (an ears rig etc..). I'll use one on 1:3 and 1:4 systems. Hope this helps!
@@billylaguardia has your band run into any interference with this passive unit? I would hate to get rf or ground loops from Foh.
@@ScottFuckinRitchie nope, it has been fine. You occasionally need to lift a ground with a barrel adapter. This is the cost:size trade off when building a split of this size. Most people want something small and cheap, especially when it’s for a band on a minimal budget. Once you add something as simple as a lift switch, the cost and size increases.
@@billylaguardia cool. Thanks for the reply. At least a lift switch isn't nearly as expensive as a transformer.
@@ScottFuckinRitchie With these builds, its not the component cost. Its the labor to wire by hand, and the area that the switch will consume. Though simple toggle switches are small, when multiplied by 32ch , a 3U panel grows quickly in height. This panel is meant to be inexpensive and small - in terms of height and depth.
Did i hear that correctly, "this is steel and this is aluminum and they're non conductive"? 6:57
Video editor: more contrast. Helps us see thr details that arent mentioned
Where do you get a lacing bar like that? That very clever.
Hi Karsten, the lacing bar is a custom build designed to interface with this panel.
nice diy project what's the part number for the Mogami multi core wire and the part number for the trunk lining
ditto - I have the same question
The multi core is Mogami 2932. Not sure what you mean by the trunk lining?
Drill is nice, I would look at getting electric screwdriver to not issue of possible stripping
BUT you use ZERO transformers for the split! Like wth? that's really substandard. Always go with transformer splits on serious productions. And with snakes ideally don't go with common ground but ground for each channel.
dirty work !
