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.
