I have a Technics SU-V85A amplifier that I connected a Logitech bluetooth adapter to the auxillary 1. I'm only getting sound from the left speaker. Right speaker fades in and out and crackles. Same thing in auxillary 2. It works fine in tuner, phono or tape 1\/2\/3. I plugged the cd player into both auxillary 1 and 2 and it played fine. I don't think it's an issue with the auxillary jacks. Could this be an issue of the Bluetooth not sending a strong enough signal to the auxillary jacks?
