Help with Icepower 1200as2 amp please!

Hello everyone! I am having an issue with my Icepower 1200as2 module. I have ran this amp for a few years and all of a sudden it starts going into a standby mode, then comes back on for a little while, then back to standby even when a signal is passing through. When I first built this DIY project using the 1200as2 module, I hooked up 2 LEDS on the front of the chassis. When first powering up the amp, the amber LED would light up until a signal was picked up through the RCA interconnects circuitry?  So if I wasn't playing anything through the amp, the amber LED would light up and stay on until a signal was detected. I really don't want to trash the module, so if I can get some help to perhaps fix this issue, I'd be very grateful and appreciative! Thanks for any help!




I just wanted to add that I can hear a clicking noise coming from the module when this ON/STANBY starts switching even when a signal is passing through? I have no clue why it's doing this! :(

Get the spec sheet  (really a manual) from here:


Then see how this audio sending is enabled or disabled.  It's either a jumper or switch that needs to be right.  May be dirty or not working.  Try disabling it to see if that fixes it.  If it's still going into standby mode, disconnect your amp output to ensure you don't have a short in the speaker cable or speaker.

Hi Erik and tweak1, thanks so much for your responses! Hope you all are having a good day! @erik_squires , I do have that icepower manual but not sure what I am looking for on it? The amp module was working fine for years, and all of a sudden, it started going in and out of ON and Standy modes. I can see this by the 2 LEDS that I mounted on the front of the enclosure. When the amp is first turned on, the amber LED lights up until a signal is passed through, then the blue LED comes on and plays when a signal is passed through. Not long ago I had unplugged it and took a look inside trying to see if I could notice anything visually. I unplugged all of the connectors from the board and re-plugged them back in making sure that all was secure. I then hooked the amp back up and it was working fine for a couple of weeks, then started this switching between the ON/Standby modes. I can actually hear a clicking noise when this happens. I can trouble shoot some things if I was told what to do. I have a Fluke DMM and such, but honestly wouldn't know where to start. Thanks for your concern!

@tweak1 Thanks bud, I will look him up and see if I can contact him!
