Audio Splitter With 4 Splits

Introduction: Audio Splitter With 4 Splits

About: I am an Eagle Scout. I love Hunting, Fishing, Camping, Ropework, Chain Mail, Making things in general, and i love my family.

Have you ever found yourself wanting to share the love with you music by letting your friends split off your device, but always found the everyone waslistening with one earpiece in their ear?

Well i have made the solution!!! Make your own multi-splitter!

A History first...I am a proffessional driver as i am sure most of my subscribers know, and i wanted to keep all of my audio devices attached to my in-tractor stereo of these is my computer which i plug in because i cannot hear it over my APU (Auxillery Power Unit) which also controls my HVAC to keep me cool while i sleep after a long days drive...thats where i came up with this life hack...i searched instructables for hours (like i usually do before starting a project) to find out if anyone has attempted such a feat...AANNDD UNFORTUNATELY (JUST like my popular and debatable scentsy bar project (which can be found here  ), there wasnt anything in existence to go off of...i mean there is, but not for the type audio splitter i was looking i decided to take a splitter that i was already using, and one i had just lying around and made this ible!!

Step 1: Materials

For this ible, you will need the following...

1) 2 headset splitters (preferably belkin as i am not sure what other types use actual copper wire or signal wire)
2) A pair of scissors
3) A multi-tool/pliars/etc for possible tight spots
4) Electrical Tape
5) Electrical Shrink Tubing a size that tightens down snug on the joint itself and a size just a little bigger than that to cover the rest)
6) A lighter for the shrink tubes

Step 2: Cut and Split the Splits

In this step, yout  going to cut off the splits from the original splitter, and throw ont of the splitters away. you wont be needing it.

now you will take the male end of the splitter, and strip the wires. leave a little color so you can match channel to channel.
after stripping the male end of the splitter, you will now strip all 4 female ends of the splitter, again, leaving a little of color to match channel to channel.

Step 3: Splicing

Now you will Slide your sized shrink tubing both wires of the male end of the splitter.

Now, splice the female ends together 2x2...this mean you will splice 2 female ends to each other to create 2 double splits.

After you splice the 2 female doubles, you will take one of the doubles and splice it to the male end, matching channels of course.

Take a piece of electrician's tape, and wrap it around the splice separating the channels...this does 2 things...eliminates interference from channels touching each other, and adds a little strength. At this point i should mention, that using a lineman's splice along with solder would make for a WAY better connection, BUT i have not the supplies on my truck to solder anythin, so i had to settle for just e-tape...

now take your first tube of shrink tube and slide it onto the splice. it WILL be tight, but this is how you want it to be. now test the connections in a device you can split with. if it works, then  shrink the tubing with the lighter. if it dont work, then re-splice the connections. after shrinking the tubing, re-verify that the connections are stable. if they are, then slide the second section of tubing over the first and shrink it down on the connection. and re-test the should still be fine, but hey, you never know.


Now that  have gotten home on some well deserved and well needed home time, I have had a chance to re-connect the connections of the wires. This time, I had soldered the connections. Before i soldered the connections, the sound decided (after a little while) had loosened a little bit, so a tug on the cords would have cleared the sound a little...HOWEVER, I found that when i soldered and re-shrink tubed the connections that the sound was as clear as the time before I severed the original wires. Of course this would be natural as the connections are more stable cause of the solder. You can see the pictures on this step at the end. the rest of the process is the same, just soldered instead.

Step 4: Second Set of Splices

Now you will repeat the same procedure for the second side of the splitter.

Step 5: Finished!!!

NOW if everything goes according to now have a 4-way splitter that looks like the one below (depending on the type you use).

as a final check, you should test out all 4 connections to see if they all work. if so, enjoy!!

As all of you can see this Ible has been entered into the Hack it challenge, and the hands on learning challenge

Hack It Challenge: This project was entered here because i got sick of not having what i needed for my audio splitting needs in my tractor-trailor, so i decided to venture out and make my own...and it WORKS...

Hands On Learning Challenge:  This project also carries the ability to teach how electricity flows, and can be directed, as well as split off, and still work the same as the original "device". it also demonstrates how to splice your own connections if ever needed. (in my case it was!! lol)

    I was actually thinking of using the 1/4" split with stereo 1/4" cables to split headphones to use for recording

    nice, have you noticed that the volume gets cut down significantly when you try to drive four sets of headphones at the same time?

    Oh, haha, i almost forgot about letting you know on my findings. Unfortunately i am too cheap about buying 4 sets of headsets to test your question, HOWEVER, i have managed to plug in 4 audio devices at once and have found that although all the devices play at the same time, there is no breach in quality of the sound...unless the devices are plugged in, then the interference from the charging cycle degrades quality by half. but other than that, i have found no issues. i will see what i can to to replicate your question as you originally asked it!! till then, happy making!!

    nope. the reason is cause i only run one electronic at a time...i simply wanted them simultaniously hooked to the same sound output device (my tractor's stereo radio) without having to fimble-fart around while driving to hook up the other devices.

    i think that because this is using one male splitter to 4 female connections, that the volume would likely not be affected by too much...i could see if one was using 3 splitters to obtain 4 splits to share, yes the would be potentially problematic, however, like i said, everything is "inline" so this should eliminated the problem.

    i will research this and let you know my findings!

    thank you for your comment!!

    could this same project be done with 1/4" stereo cables instead of 1/8"?

    Sorry for the late post. i am a truck driver and its difficult to get internet.

    I am sure it could be. its worth a try. If the composition of the wire isnt different, i am sure it would work, if not then i am sure one would have to simply figure a way out. the only concern in my opinion would be if the inner wire is real thick, it could cause the solder to be thicker unwantedly...kinda like you see in my project (but truth be told this porject was a hasty, with not too much time of thinking about how i would get around the little bit of material i was working with). but yeah i dont see what it would hurt to attempt with a 1/4". i am assuming that your idea is to use this as a split for an electric guitar, or multiple electronic instruments? or maby even for "dj" equipment (for short)?
