Calibration Microphone for Bang & Olufsen Beovision Avant 55, 75 and 85 TVs.

Connect this to your Beovision Avant TV, place the microphone in your listening position, and use the TV menu to select automatic calibration, to set up the surround sound perfectly for your seating position. It has a VERY long cable!

I bought this by mistake thinking it would be compatible with my other model of B&O TV but it isn't, hence the sale.

It is in the box and is in great condition, it may even be unused.
