Onkyo TS-DS575X Quirk with Sub (1 Viewer)

[mpac1]

Finally unboxed this after two years only to find that when I connect a cable to the sub out jack the right front channel goes dead. This happens even if it's just a cable with nothing attached to it. Checked cable to sub (as well as open end cable) and no sign of a short or resistance. Didn't use a sub before so not sure how long this has been going on. Know this is old technology but for my room will fill my needs. Any idea as to what I'm missing?? Thanks in advance!!

Did you try a different cable? Maybe the receiver is defective. Years ago I had a brand new Onkyo TX-DS696 with a dead channel right out of the box. The dealer exchanged it for another working unit right away. If there is one lesson to be learned, always check out new equipment immediately to make sure it works.

This one was given to me. What did confuse me was the RF channel going out with just a cable with nothing at the other end. As a long shot, I'm thinking about putting a q-tip in and see if something is stuck in there that is shorting that circuit out. Crazy mystery to me.... Thanks!
