dipskhatri Posted June 14, 2022 Share Posted June 14, 2022 I have had my C4 audio Matrix for a while and recently it stopped working. I contacted my dealer who then rang C4 and they said they wont repair it, but they did say we are pretty sure its the Power Supply that is causing the issue. I live in London UK, does anyone know who can fix this for me or where can I get the part for it? Any help or guidance would be appreciated as I don't want to spend another coupe of thousand pounds in getting a new one, cant afford it right now.

lippavisual Posted June 14, 2022 Share Posted June 14, 2022 I recently went through this for a customer. The power supply that is in the matrix is no longer available. I found a Meanwell power supply that should have been a direct replacement, but it was on backorder until March 2023. I found another Meanwell that had a larger Amp rating and went for it anyways (purchased an extra too). Installed it and all is working well again. If its a V2/V3 Audio Matrix, you'll need a 5V/10Amp supply and the appropriate Molex connectors to swap on the wiring. I purchased the NFM-20-5 Quote Link to comment Share on other sites More sharing options...
dipskhatri Posted June 21, 2022 Author Share Posted June 21, 2022 Thank you for the info I have V3 and the attached is the PS in the matrix. Would this be the correct one to get? https://gb.wiautomation.com/mean-well/power-supply/NFM205?utm_source=shopping_free&utm_medium=organic&utm_content=GB213628&gclid=Cj0KCQjw2MWVBhCQARIsAIjbwoNhcg5SmF02fqsQz1_DaWfWLqqijQjrVM9KQm_c7s8SVVzGje-kV90aAh18EALw_wcB Quote Link to comment Share on other sites More sharing options...
lippavisual Posted June 21, 2022 Share Posted June 21, 2022 That would be it. Same one I purchased. Now you either have to splice into the existing wiring that goes to the board or buy the right Molex connectors to mate to the new power supply.

Unfortunately I cant get hold of this power supply no one has it in stock anymore, so they have recommended this one in replacement https://www.digikey.co.uk/en/products/detail/xp-power/ECL25US05-T/4785611 I assume this should work?

cfgenie Posted July 12, 2022 Share Posted July 12, 2022 hi, did you find that power supply somewhere? the link you posted says lead time 37 weeks Quote Link to comment Share on other sites More sharing options...
zaphod Posted July 12, 2022 Share Posted July 12, 2022 That looks like the same power supply as an HC-300. Does anyone know if that is the case? If so you could try buying an HC-300 on ebay. This is a picture of the inside of an HC-300 with the power supply Quote Link to comment Share on other sites More sharing options...
lippavisual Posted July 12, 2022 Share Posted July 12, 2022 They look similar. Almost positive the HC300 was 12V vs. the matrix requires 5V. Only way to know is to open it up and read the power supply. Either way, the old Gongdha power supplies are no where to be found so choose a manufacturer that has a great reputation for power supplies and make your modifications. Meanwell is the best I've dealt with. Quote Link to comment Share on other sites More sharing options...
Ryanjackson Posted July 12, 2022 Share Posted July 12, 2022 I just replaced a power supply yesterday with this one on a amsv3. Had to change the wiring leads but works good. https://www.digikey.ca/en/products/detail/xp-power/ECL25US05-T/4785611?utm_medium=email&utm_source=oce&utm_campaign=4251_OCE22RT&utm_content=productdetail_CA&utm_cid=2998528&so=76664085&mkt_tok=MDI4LVNYSy01MDcAAAGFaPp0vnCre3EueWADizYpfRKaF1IM8uJyas_7lb9y2lVA7JWS7QDzk3zlkoth2TfUNij_Zo0hIA6ACVJiSEc_UySiIQnKHdUTlQdVA63T Quote Link to comment Share on other sites More sharing options...
Ryanjackson Posted July 12, 2022 Share Posted July 12, 2022 it says lead time for new orders is 37 weeks, but there are 179 in stock. At least on the .ca website. Ryan Quote Link to comment Share on other sites More sharing options...

Did you change the the original wires in the unit to fit that power supply? Quote Link to comment Share on other sites More sharing options...

Buffalo Mike Posted September 23, 2022 Share Posted September 23, 2022 My C4 audio matrix died during a power outage. is the power supply internal or external? how easy is the repair? Quote Link to comment Share on other sites More sharing options...
dipskhatri Posted September 23, 2022 Author Share Posted September 23, 2022 Its internal and very easy, plug and play providing you get the exact replacement. Quote Link to comment Share on other sites More sharing options...

Matt Lowe Posted September 23, 2022 Share Posted September 23, 2022 you can also do an external power supply of similar output. We did this as finding a drop in internal power supply was more difficult and costly. Quote Link to comment Share on other sites More sharing options...
txfanatic Posted December 26, 2022 Share Posted December 26, 2022 I'm running into the same 16x16 audio matrix as everyone else...will pick up one of thesehttps://www.mouser.com/ProductDetail/XP-Power/ECL15US05-T?qs=w%2Fv1CP2dgqoNOSGDo4%2FKYw%3D%3D&mgh=1&gclid=CjwKCAiAqaWdBhAvEiwAGAQlto835awdhGul4JrHJRgjFNZy-Hmtw2yQ6c4fmp3Qllu258ShXw-XYhoCEtwQAvD_BwE but wanted to see if this would be a decent external solution that seems ever so easy to do the quick splice for the DC connectorhttps://www.amazon.com/ALITOVE-100V-240V-Converter-5-5x2-1mm-Security/dp/B078RXZM4C?th=1 Thanks C4 fam Quote Link to comment Share on other sites More sharing options...
txfanatic Posted December 30, 2022 Share Posted December 30, 2022 Turns out the power supply unit was fine...I wired the new PSU and the unit did not power on (and when i tested the old PSU, it was showing proper voltage)...is there another quick fix? I'm probably going to buy a new unit, but want to research it (will do some searches in these forums) Thanks Quote Link to comment Share on other sites More sharing options...

I think I will cut the blue and brown DC wires and splice in a female barrel connector for the DC connection. And splice into the wires on the AC side as well. And then just use tie wraps to fasten the brick inside the case through the vents. Lots of empty space in those cases! Any idea what type of connectors are used on either end of the power supply and the spot where the DC power connects to the main circuit board?
