Harmon Kardon AV-145 audio problems (1 Viewer)

[lbk]

I'm new to the forum. I was hoping someone could help me troubleshoot my audio problems.

I just bought a new HK AV-145. My subwoofer keeps cutting out but only through my cable box. I don't know why. If I toggle the volume, it will kick in, but then it cuts out again a short time later.

The problem does not lie in the subwoofer (I believe) because I have no problems when playing audio through my dvd player.

Originally, I had both the digital audio cable and the composite audio running from my cable box to my receiver. The cut out problem was really bad. Then I removed the digital audio and just ran the composite cable and things were better, but the problem still persisted. What could be causing this? Is it a weak audio signal from the cable box that doesn't doesn't provide the adequate bass frequency? Has anyone ever encountered a problem like this?

Thanks.

Have you tried the cable on a nother componet? highly unlike but maybe I'ts a faulty cable and you could be getting brake up, maybe through connection or RF interferences. Sometimes this boxes just do not out put through the coax very well. Call your supplier and see if there are any problems with your cable box. I have seen this problem in the past. Don't know if this is a help for you, but maybe a start.

My guess would be a faulty cable box or faulty cables and not the fault of your H/K AVR. Try other cables first, if problem persists, ask your cable company for a new box.

Thats what I think as well.

Thanks for the input - I guess that i'm slowly coming to the conclusion that its the cable carrier. I have two boxes - 1 is a Scitentific Atlanta and the other is a Pioneer. Both of them work very well when hooked up to my sony sound system, and they both have the same problem when I hook up to my HK. All the calbes are new, and I've swithed the cables back and forth between the two systems - I know the cables are all good.

I really don't know what to do now - I know that when I talk to the cable company, they will say - hmmm - never heard of that problem before - it must be the receiver.

Is it possible that the cable carrier just doesn't have an adequate signal for the HK?
