Thanks. New build for me. I bought the module on ebay. This is the test case. I'll verify the 10v and then chalk it up to learning experience.

typo on the - the three pins are all ~5v Here are the Amp on measurements with the j6.3 to j6.9 connected J6.1 to j6.3 = 4.5V j6.2 to j6.3 = 5.2V j6.4 to j6.3 = 6.1V

really sorry - first measurements the amp was off Here are the Amp on measurements with the j6.3 to j6.9 connected J6.1 to j6.3 -4.5V. j6.2 to j6.3 = .5.2V j6.4 to j6.3 = 6.1V

so with the j6.3 to j6.9 connected J6.1 to j6.3 0.5 mV j6.2 to j6.3 = 0.6 mV j6.4 to j6.3 = 0.8 mV

thanks for the help. The data sheet for the J7 says its for a tweeter amp and should not be used for other purposes. The J4 is the main out

retrying on J6. without the jumper I get 5 volts between j6.3 and j6.4

wait - sorry I was on the J4 connector

So 1 to 4 is 10.25 and 2 to 4 is 10.36

I get 0v between j6.3 and j6.4

Hi all, I'm at a loss to figure out what's wrong with my Hypex NC500mp build but I'm not getting any sound from it. I have a balanced input that I've verified works fine through my Crown D75 but when I swap in the NC500MP I get nothing. These units have the built in power supply and I"ve...

Well - finally fired up the amp to test it and alas no sound. I hear an audible click when turn the on on which I assume is the amp going from standby to on but no sound is coming through the amp. I checked for any DC on the circuit and only see a few Mv. Anyone have any ideas for what I...

Another question for you guys. I bought a cheap case on ebay - the case has is thin aluminum and has "rails" on the bottom. Is that an issue for the heat sink/cooling?

NTK - thank you for the diagrams and the assurance that I'm on the right track. Wasn't 100% sure on the signal to case. I think I'll use the "extra" ground pin on the Neutrix connector unless I'm told I should make another connection to the case. Not as pretty as a lot of builds here but it...

HI all, I'm building a NC500MP mono amp to power a Rel Britannia sub. I'll be using a MiniDSP Flex for crossover and DSP. Amp is almost together but I want to check-in to be sure I understand the singal wiring correctly. On the XLR to Hypex board(J4)connection I'm using shielded microphone...

Just got notified that my flex has shipped by DHL. Hope to see it on Monday. I'm happy!

Thanks Geronimo. I ordered 6 days after you so I have hope. Did you receive any shipping notification form MiniDSP when it was sent?

If you recently received a Flex balanced in the US, can you let me know when you ordered it? Ordered mine last week and just trying to gauge when I might see it. Itching to dive into the DSP rabbit hole. Thank you!
