Hi everyone,
I found this forum through one of the guys on Audiokarma.
I recently rescued a Depth sub from a goodwill store near me. It seems to power up, and for the price, I couldn't leave it behind. 1 of the 3 grill covers is a little cracked, but otherwise it's in good cosmetic shape.
The problem is, it doesn't seem to work. I can supply a signal, but I get no output. The led changes from amber to green as it should, but no sound comes out. I've used speaker level and line level inputs without success. I can hear a very faint turn on thump, but no sound, regardless of level. I can feel the speaker cones vibrating very slightly when the unit is on. When I switch it off, the vibration stops.
It seems like the amplifier just isn't getting the signal.
Thanks to your serial number pdf, I can say that my unit was made in April '05.
Has anyone experienced anything similar with your equipment? Any known issues with these units? How's the ML service department?
I've started communicating by email with someone in ML's service dept. They seem to be much friendlier and more supportive than I've encountered from other manufacturers. Hopefully they'll be able to let me know if parts are available and what the costs would be. I'm just hoping someone here might have a little additional info to help my troubleshooting.
Thanks!
Brian
