Hi, my reciever has no bluetooth (RXV373), so I bought a Harman Kardon Adapt bluetooth adapter.\n\nNow I need to find a way to connect it to my reciever.\n\nIt has an input of Audio Out, Mic In or Audio In.\n\nI thought I'll use RCA cables, in this way :\n\nWhite and red connect to my reciever Audio input in the back, and white OR red ( since the adapter has only 1 "Audio Out" connection), to the adapter. All it does is loud white noise, nothing else. And the adapter is connected to my phone and seems to be streaming, but the sound doesn't go to the reciever.\n\n\n\nIf I connect the red or white RCA end to the adapter, the said noise comes out of the right or left stereo speaker.\n\n\n\nI know I am supposed to connect both red and white to the adapter, but it has only one input for Audio Out.\n\n\n\nThe Harman and Kadron Adapt manual doesn't help.\n\nHow do I connect this to my reciever to stream sound??\n\nEDIT: I used an Aux cable and connected the adapter to the reciever's front aux connection.\n\nNow it works, but the sound quality doesn't compare to when I connect the phone to my smart TV via bluetooth (TV is connected to reciever via HDMI ARC).\n\n\n\nSo. Is the cheap aux cable degrading the quality of sound? Is there an alternative cable connection to connect this bluetooth adapter, that has only one audio out connection, to my reciever? Some other high quality cable that isn't aux ( or just a better aux)?
