I took an LG TV cheat, which does not have analog audio output even for headphones. The Sound on the TV would be perfect if it also could play frequencies lower than 100 Hz. As He doesn't, I thought I'd attach an audio system.
An audio system that has optical input is, however, quite expensive, more expensive than the TV I could say!
Two months Later, my device arrived. It Works perfectly. It'S got everything: USB power cable, Toslink optical Cable. As soon as I unpacked it, I connected it to the USB jack on the TV, I muted the optical cable and plugged it into the audio system through the RCA jacks, and now I have enough for the small room where the TV is placed!
