How to Wire a Double-Zone Snare or Tom




Introduction: How to Wire a Double-Zone Snare or Tom

About: I am a musician, but not professional, I have been in many bands over 18 years and have different experiences from them. Being in the military (Navy) I have been around the world a few times so I got to see ...

This tutorial  can be used for ANY  acoustic- to- electronic drum conversion with minimum alteration needed.
It contains detailed images and instructions that should explain the process in a way that many words may not.
I am learning how to do this as I go, so if you have better ideas please share them!.
I have been working on building electronic sets for only a few months and sometimes I figure out better designs after the prototype that I've built is finished. That said, if I find a better way to tackle a project, I will post an update to save everybody else the  part of having to find out the hard way like me. As any other Diy'er out there knows, the internet and sites like this are what we use to learn and sometimes teach each other, I give credit to the authors of  sites that I used to learn and design this and other tutorials posted in YouTube under  the user name Lucyferina.
Feel free to ask any questions about this mode or any ideas you might have, if I know the answer I will gladly answer and if not, at least will try to point you in the right direction.
Happy drumming!!

One last thing..... If you need to see a bigger version of the pictures click on the "i" icon on the left top corner of the picture, this allows you to select a bigger version and read the text that I added to them.

Step 1: Create a Bridge

This First step is to Create a bridge for the head piezo that should span from one side of the drum to the other. in order to maintain the drum integrity, the bridge is mounted to the drum utilizing the screws that hold the drum lugs and "L" brackets as shown in the accompanying image.  In order to prevent double triggering from the rim piezo, rubber washers can be utilized between the "L" bracket and the lugs as well as the bridge itself.

Step 2: Mount the Head Piezo to the Bridge

Once the bridge is installed, the next part is to mount the piezo sensor on top of the bridge, in the case of Roland modules, the piezo should be sandwiched between the bridge and the foam cone  by double sided tape,( For proper sensitivity, the piezo sensor gets positioned wire side down facing the double sided tape and the copper only side facing the foam) I don't have a Roland module to confirm this but in the Roland forums people agree that the head doesn't have a lot of contact with the foam to get a better response.
In the case of Alesis modules a foam block is used instead. Roughly a 2 inch by one inch rectangle, this should be big enough to cover the piezo which gets positioned  below the double sided tape between the head and the foam block wire side facing the foam block. in my case, I put a piece of double sided tape on top of the foam, then the sensor cable side facing the sponge block, then another piece of double sided tape on top of the piezo facing the drum head, also in my case the piezo turned out to be too sensitive when placed in the center so I ended up placing it closer to the rim (Roughly 2 inches away from the drum wall) This allowed me to create a mini bridge which only uses a wood square of roughly 4 inches by 4 inches and a single "L" bracket  to hold the head piezo. This also help utilize less cable to wire the sensors when creating a double zone drum.

Step 3: Add Rim Piezo Sensor

The next step is to add a piezo sensor for the rim of the drum which will allow us to play a snare rim if using a snare or cymbals, cowbells, or other percussion sounds, or any other samples that your module or software will allow.
A breakdown on modules that I know:

Alesis DM5  does not allow double zone but does have enough trigger inputs (12) that you could wire a drum a little differently and actually have a double zone drum (Or cymbal).
the DM5 does have MIDI out which allows it to trigger software. a MIDI to USB adapter is needed to connect it to a computer.

Alesis i/O it has 10 inputs all of them double zone (When using a TRS cable)  TRS picture on the following steps. This is not a drum module but instead a Trigger to USB interface, it does NOT produce any sounds but instead allows you to play software like BFD2 , Superior Drummer, EZ Drummer, Steven Slate Drums (which is the one I have) and more similar programs, The programs just mentioned are far better than any stand alone module due to the variety of sounds that you can get from any drum (some have over 90 velocity layers) making for a very realistic drum experience which mimics the real thing so closely you'll wonder how you played anything else before.

Roland   Almost all Roland modules that you can buy today have MIDI out capability and at least some double zone inputs, more modern modules even have triple zone capabilities and even MP3 inputs to play along with your favorite tracks and some other fancy features that make them more than capable to support any electronic drum kit.

My personal preference is the Alesis I/O because of it's price and capabilities, it doesn't support triple zone but the only part where I would need it is for the ride cymbal.  I am  working on a way to do a triple zone cymbal on a double zone input, I think it has been done by racer52online in YouTube under "DIY Dual Zone Cymbal with Choke.MPG"

Step 4: Wiring the Piezos for Head and Rim Triggering

The picture included shows the proper wiring for the Alesis modules, this should work for the Roland and others but if in doubt you can look up on your module manufacture's forum for the particular wiring of the piezos. Again in the picture you see the recommendations for the different foam (cone or block) and also how far both the cone and the block need to be above the head level in order to offer resistance and provide good sensitivity to the piezo.

Step 5: Wiring Explained

Simple image that shows how to properly wire a double zone snare, or tom, this can also be used to wire a cymbal for bell and bow.
That also shows what a TRS connector looks like.

    Question 3 months ago on Step 4

    Please can you explain the polarity of your piezo?
    I know that most of the piezo have the red as positive,and black as negative.
    I use RTB trigger and the polarity in their trigger is viceversa,the red are the negative.

    And one more question.
    I use as a female connector. The female connector is
    I hope that the sleeve is in middle ,the small is ring and the smallest is tip.
    Is it good?
    Thank you for your answer
    P.S:I own a strike module with original cables

    I know you can find piezo polarities with a Google search, but at the time I made this I was using the polarities recommended by Alesis, in either case, if you make a double zone pad, before you solder the connection, use alligator clips to test, that way you will know which piezo is rim and which is head, make sure to set your module for piezo/piezo and not piezo/switch. I believe the wiring diagram for Alesis modules will be under Alesisdrummer,com

    Thank you very much

    I bought a Roland TD-6 that came with a whole bunch of auxiliary electronic percussion equipment included:

    -Alesis D4 module / brain
    -11 cymbal boom arms w clamps, foams, and washers
    -10 home made drum pads (metal plates w foam and rubber covering; piezoelectric sensors with RCA outputs

    I just use the TD-6 on its own, so I'm thinking that these items might be of interest to those in this forum. I live in Vancouver, BC, and my email is

    If you know of anyone that might be interested, please pass this along.

    I don't personally know any other drummers in the area (middle of nowhere WV)
    but I recommend that you check the Roland forum,i'm sure there will be plenty of interested people there.

    Thanks!, the idea was to maintain the integrity of the drums as much as possible while at the same time making a very functional electronic drum for as little $$ as possible.

    Well done Man, well done!. Something similar I do with my alesis DM5 and Sonor acoustic drumset combined with mesh heads. Works perfect for me.
    Here are you can find some links I used for this project:
    If somebody have some question I will be glad to try to answer
