I had some inteference with my Rogers wave, TV signal and all my audio video in the same area. This was installed by Bell canada some time ago and it helped with interference.

The model I got was EDA 2400
This cleaned up the signal from my cable. My TV cable is soooooooooo clear. My internet does not drop anymore. The hiss from my old speakers dissapeared.
