VTF-1 MK3 not working
I bought an VTF-1 MK3 this last March and happily used it for 3 months until the space below my office became occupied and I didn't want to boom them out. So lately I decided to hook that in as a second sub for my main system and when I did I can't get it to work. I am hoping that this is due to user error! When I plug it in the lights all come on but when I play a signal though it there is no sound. I turned everything off and pulled the rca jack from the sub that is working. I knew there was signal coming through that cable and when I plugged that cable into the VTF-1 MK3 I still didn't get any sound.
Is there something simple that I may be missing? Are there some tests i can do to see what might be amiss? I love the sub and it worked flawlessly when I started using it. Would love any feedback.
