The device controls. It's a mystery to me how one can hear that. Or on what a lousy system you have to use the device, so one does not notice. I go now times not assume that this is an isolated case with me.
Completely regardless of the source or destination override highs and noisy middle and then end up in a clatter. I tested the unit in a BMW 7 Series built in 2011 with the second largest audio system and a Yamaha RX 1030A with B & W speakers. Every og sound. When I go into the plant directly via AUX or CD, that does not happen. Thus, unfortunately, the chip in the adapter smashed the sound.
