Did I ordered this converter to use the JVC analog amplifier can continue and to avoid the purchase of a more expensive home theater system. Because of the many positive reviews I decided for this model. Delivery was fast, all packed neatly, guidance was adequate in both German and English. Flight Toslink connected to my Panasonic TX-ETS61 connected RCA cable to the JVC and the adjustments described in the TV set manual. And .... nothing just noise. Well, a little playing around with ... to no avail. Cables exchanged, also connected to another Panasonic plasma, the same procedure all to no avail. Kommnuiziert with the manufacturer via email. Goods wircklich quick with her answer, but I could not help also. So I got the converter again bagged and sent back. Money was refunded shortly afterwards without any problems again. Too Bad. Maybe it's on TV. In the reviews of the other (satisfied) buyers often Samsung or Phillips called devices.
