View Full Version : Radio Matrix Issues

I havent run into this issue since this is my first year doing this. But i have a small Radio Matrix that worked really well for Halloween and now for Christmas im having a few issues. Thinking my issue is either a power issue and i need to move it closer to the controller or power inject or there is an issue with the wiring. Out of the controller i connect the pigtail direct to Matrix and it works just fine. I made an extension cable approx 20' long and when i connect it, random pixels light up and it doesnt display the radio just crazy flickering. So just wanting some confirmation on what the issue is before i tear apart my extension cable or order a new enclosure for power injection. Thanks for any help!

Your controller cant drive through the cable (some can, some cant). You might try adjusting the output resistor to be more closely aligned with the impedance of the cable. Personally I find the procedure to do this pretty tiresome. My solution is to cut the cable in half and insert a buffer/driver or a null pixel into the line. This usually takes care of the issue.

Thanks for the info. Ill try that and see what happens. May just place it closer to controller for this season and play with it in the offseason.
