For those familiar with my loss of sub-signal problem. Is it possible that the sub Y cables could be defective.
Recap and where I stand today - The only way to get my subwoofer to play is to use the receiver auto setup feature (yamaha - ypao). It identifies the sub, sets main speakers to large and xover at 40hhz. I change the xover to 60 and sub to both to play in 2 channal also.....When I shut down the system for an extended period of time, the sub doesnt play when the system is restarted (have to do the auto setup again).
Both yamaha (after I proved prob not sub) and klipsch (thought possible problem with powered sub amp) were at a lost and both recommended taking in their product for service. Just not being able to let it go, i am out to isolate where the prob is before I take it anywhere.
First elimination - Went out and got another sub (to return of course) :D .. Hooked it up and the same problem (also learned bigger cabinet makes a huge difference). Newer model of same sub, much better sound. Cant buy yet still have not gotten a friggen amp yet :( ......Strike the sub as source of the problem.
That leaves the reciever, maybe something wrong with the sub preout, or some sort of internal short when I shut the receiver down?
While researching interconnect cables for future amp, I started wondering about possible faulty cables. They are cheap radioshack 24K subwoofer Y cable. Is it possible that it needs a big shot of juice from the receiver to kickstart?
