Hi everyone,
I have recently bought two amplifiers Icepower 1200AS1 from you (at the beginning of may this year). Finally I had time to connect both modules and everything seemed to be working fine for the first 10 minutes, thereafter one module stopped working. And ever since it does not work. It seems that the power supply is working but the actual amplification module is not working. When I power up the module, there are weird sounds coming out of the power supply, please see the attached video. Those weird sounds stop after 20-30 seconds but nothing else happens. There is no sound coming out of the module no matter what just some hum-noise. The power supply is warm to touch similar to the working module but the amplification coil (the small one next to the output) is cold.
Can you please help if there is something I could do? I checked the connections and those are fine. This problem is there even if I change powersupply cables, or if I detach output or input cables. I even tried to disconnect it from electricity for 2 days and it is still there. I tried to measure output volts, working module has around 6-6.5v when no music is playing. The faulty module has like minus 15v which is weird.

Many thanks for help.

Well, it seems that module goes straight into protection mode a tries to go out of it repeatedly during the first 30 seconds and then it seems it stays in protection mode. It does that regardless there is input or output connected
Thanks for hint. I tried it and the problem was still there. There were two identical modules, a and b, at the beginning, both worked perfectly, after 10 mins the second one stopped working. Tried different combinations like just one module, or different cable, without any inputs/outputs connected, and still not luck. Could be faulty module, I will send it back to ICEPOWER and they will asssess it under warranty.
If they are genuine ICE Power modules from Band & Olufsen, they will exchange it under warranty. If Chinesium copies, time to either try for a PayPal refund as it is not working, repair it or purchase new.
As far as i know, They should be genuine. Bought them from reputable seller from Italy. He is going to send them to ICEpower for warranty check.
As far as I know, there were some asx125 fakes or 500 but not 1200as1/as2 fakes.

I have had the same problem with my 1200AS2 module. It worked for almost year and then all of a sudden the protection circuit cuts in every ten minutes or so. All came back to work after powering it down and up again. You can verify if it is the protection circuit by measuring the output on the protection control pin, see the manual.
I have sent the module back and have gotten a new one under warranty that functions for around 1.5 years now without a problem.

Hello, I have the same problem exactly as you show in the video, the question is what did you do in the end it works or did you return it
