Ncore 400 no longer working...
« on: 15 Feb 2014, 12:49 am »
I was doing some work on a DIY preamp & while trying to isolate some noise I moved my input to the amp, heard some more noise then no sound.  I use balanced inputs, which I did wiggle at the connection.  Not sure if I shorted something?  The lights come so the fuse should be good.  I know I will have to swap pieces with its mate to isolate which board is at fault.  Just wondering if anyone may have any insight to this problem.  Thank you!

Cheers,

Jeff

I have had no luck finding the problem. The amp board lights up. I guess that this just shows it is receiving power & not that the amp is working properly. For anyone who has gotten into the guts of these boards, is there any thing I should test with a meter? 

Thinking I may have fried a circuit somehow I have emailed Hypex to see if they can do anything for me.

Is it both amps?  Have you swapped channels?  Have you swapped NC400 boards?


What trouble shooting have you done?

The trouble is with one amp.  It is a monoblock configuration.  I will swap boards today to see if the trouble is the amp or PSU.   

All I've done so far is swap cables & checked the connections.

Thanks!

Swapped the boards & it's the NC400 that's blown.  Not a good weekend.

Hypex sent me a new amp.  Back in business.  Great customer service!
