Not sure if this is the right area to post this,
I am running my xsp-1 home theater bypass to add my Seaton Submersive F2 to watch movies with(Seaton is in my 2 channel setup with airmotiv 6's). I am hearing some feedback coming from the sub when I run it this way. I don't hear the feedback when I play any music through my xda-1-->xsp-1-->airmotivs/seaton connection. I am running a really long rca cable(25ft) from my denon 4311 to the xsp-1. Is it the cable quality or something else causing the feedback? I am pretty new to this, but I am fully addicted. Any advice? Sorry if I posted this in the wrong section. Thanks for your time

Are you SURE what you're hearing is feedback? Normally, you only get feedback when there is a mechanical path for the sound between the output and the input - for example, when a sub causes a turntable to vibrate, and the vibrations are in turn picked up by the cartridge. If it's really feedback, and you aren't using a turntable, then the only reasonable candidate would be if you have an interconnect running next to a speaker cable for some distance (things like Blu_Rays and CD players are generally NOT subject to feedback). If it's just a noise, then it may be something else - if so you need to be more specific about what you're hearing and when.

It is a low level hum I hear from the subwoofer, the volume level of the hum stays the same regardless of listening volume. You are correct, feedback probably isn't the correct term, as you can tell I haven't been doing this for too long. Thanks again

Try taking a piece of speaker wire and touch one end to the chassis of your preamp and the other end to the subwoofer amplifier heat sink, see if the hum stops. |
