Super SD System 3 Audio Buzzing FIX TUTORIAL

18 Jun 2018, 15:27

All boards shipped from 18-06-2018 contain this fix


Hello everyone,

We would like to introduce our oficial guide about how to fix the audio buzzing issue.

FAQ :

- Whats the Audio Buzzing issue about ?

Factory unmoded Super SD System 3 boards suffer from a audio buzzing when data is being accessed from the microsd. This buzzing is more noticiable on Framemeisters and other high end solutions than on regular tvs. For some users is really disturbing.

- How can Audio Buzzing be fixed ?

Just soldering a 10uf 10v electrolitic capacitor like this one.

- Would a 10uf 20v electrolitic capacitor fix the issue ?

Yes, as log as is atleast 10v its ok, 20v or any other higher value will work.

- who discovered the fix ?

FBX, we would like to show our gratitude to him for make Super SD System 3 better with this fix

- How can i know if my board has the fix ?

If your board was shipped before 17-06-2018 it dosen´t has the fix. All boards shipped from this date contain the fix

- How can the fix be performed ?

There are a lot of places to solder it such as on the top of the pcb, but we can only recomend to solder it on the back of the pcb just to avoid damaging the resistors while soldering.
Solder the cap on the top of the pcb at your own risk, do it on the back of the pcb as this tutorial to get oficial support.

Steps :

1. Locate this area on the back of the pcb

2. Solder on those two points

Image

3. Remember that the capacitor has polarity

Image

4. Just cut a leg and blend the other one

Image

Thats all, its a simple fix and removes the buzzing.

For reference, there is a lot of free space on the shell to fit the cap under the pcb

Image

And this is how the shell with the cap on the back looks like, once assembled

Special thanks to everyone that helped on this to be a reality :
FBX (FirebrandX), Mobiusstriptech, Ace, Todd and everyone else





We are getting some emails of people damaging the pcbs while doing the mod on the TOP layer of the pcb (following FBX´s original mod that is different than the one described here)

Please, follow this guide and do it only in the back of the pcb as described here.
Its easy to break the resistor doing it on the top of the pcb (as described on FBX´s original picture) if you are not used to solder smd resistors. The legs of those electrolitic caps tend to be strong and make excesive strength once soldered on the resistor. Its easy to broke the resistor and get no audio as an issue caused by that.

Again :

Doing the mod on the back of the pcb is easy and 90% risk free

Doing the mod on the top of the pcb requires certain skills, if you lack of those don´t touch it.

You don't.

You send it back for a Rev 2 replacement that has already been fixed.

EDIT :

i just tried it on a V1, the via to make it on the back is missing so you would have to make it on the top of the pcb.

Same thing as other posted before :

This is really great. I have no soldering skills whatsoever, so hopefully I can find someone to do it for me within the US.
