Db25 multicore cables are very common at any studio, a lot of standard audio gear interfaces use them, but maybe you don´t know how to make them. Here a small tutorial if you prefer to build them and save some money.
I must say you have to spend some time and work, but it’s not difficult. You will need the appropriate tools and a little patience and skill for making a professional work.
Most used multicore are Tascam pinout, followed by Yamaha pinout.
Tools needed for making your DB25 multicore cables
You will need these components for making a quality DB25 snake:
Soldering tin (I use WTB tin with 4% silver, great quality, and sound), soldering iron, multimeter, lathe, tweezers, wire stripper, cutter, shrink tubing, and of course quality multicore cable.
You can use a magnifying lens to see better welding.
Connectors and cable for making your DB25 multicore
Mogami is one of the most used, very good quality, but I prefer Gepco snake, great sound, low noise and cheaper option. Apart it has a type of sound I really like. Very similar to Mogami.
We will choose the connectors. XLR, Jacks, bantam or bare wire for soldering in a patch bay. I like black Neutrik pin gold connectors, great quality, and sound, and they look cool.
It is preferable to use quality DB25 metallic hood connectors than plastic housing.
All these materials count for better sound quality. I tested more expensive commercial snakes vs mine and I prefer the sound of my Gepcos. I can really hear better small nuances on my Lipinski and Amphion speakers.
The procedure of the DB25 snake
Cut the length needed of your snake. You will have to add the cable length connections.
So If you need a db25 snake of 1.5 meters, add 5cm for the db25 connector and 30cm for XLR or Jack connectors.
Stripe the side of db25 connector:
Once stripped soldering all wire tips with a drop of tin. After that enter a shrink tube on each channel cable, 4mm shrink tube fits fine.
Now repeat the previous step with the XLR or Jacks connectors side. On this side, shrink tube is not needed.
Now, will begin with DB25 soldering, put the connector on your lathe, we soldering the top row.
First fill the pins with a drop of tin, after that solder the cables following Tascam or Yamaha pinout, see below picture.
When finish turns the connector, we will repeat the above step with the bottom row.
After soldering all db25 pins we will test the snake with the multimeter. It is important to ensure that the work done is correct.
This will save time and errors,
If your testing it´s OK we will solder the other side. Solder your XLR, Jacks or Bantam connectors.
After finish check again with your multimeter.
