Hey Team, I'm new to the forum so thanks for having me!, I am using a DD-1 and have a problem that is probably simple to diagnose for people who have been using the dd-1 for a long time, my issue is, I have no signal light, all the other lights function correctly, the 40hz and 1khz Led's light up as they should and so does the distortion light, I just can't get the signal led to light up, whether I'm testing at the deck or at the amp, whether I'm testing RCA or speaker outputs, I have tried multiple different aftermarket head units and amps but they are all the same, no signal but everything else works as it should, should I just not worry about it or can someone give me a reason why? all help is appreciated.
