I have a TMS-3. They're not that complicated. If you have specific questions perhaps I could answer them.
Can u send me a email of the Russound TMS-3 manual? beckermichael24@gmail.comIt turns out I still have the original manual for my TMS-3. I thought it was lost in the mists of time. PM me with your email address and I'll send a scan of it to you as an email attachment.
After looking at the manual I see that what I have is a TMS-1. Doh! It says TMS-1 on the box. Where I got TMS-3 from I have no idea. Regardless, the offer of a scan still stands.
