Hopefully someone can assure me that this can be sorted out relatively easily! I've had my amp for a couple of weeks now - bought off eBay - the previous owner stated that it was bought new 18 months ago. Everything has been perfect until this morning. The kids were watching tv and all of a sudden, the input switched from A4 (the fixed AV input) to A1 (the input I have for music). This caused a sudden silence in volume as the kids programme was in stereo. I have my Moon connected to the pre outs of my Sony AV receiver. I'm going to try and change inputs but this is not ideal as there is only the A4 input that can be fixed. Could this be something to do with the Sony even? Any ideas/info would be appreciated.
