Hi all,
I'm now finished with my project of building a 5 ch HT power-amp.
It is based on 2 SPS80 from coldamp and 5 UCD400AD's.
And, at this point, 'el-cheapo' cables and connectors.
But I need help and hints.
The thing is, it is dead.
I've connected one channel, but speaker is dead.
Or more correct, if I press the speaker to my ears, I can hear a faint sound originating from the CD.
I have measued voltages from the SPS80 and it seems ok.
Any hints?
I really dont want to test another channel before
I have understood what this is about.
Cheers
Erland

Hi again,
Ok, so my question might just have been a tad unclear ...
More specifically, How can I determine signs of life on the ucd?
As I hear a faint sound from the speakers I'm fairly shure I have not shortened in's or out's.
Supply voltage seems to be within spec.
Should I dare to take thr next ucd in line and try there?
(And possibly blow two ...)
So far, I have done no changes to neither th ucd400's nor the sps80's. For instance the OP does not have a separate power feed.
