Okay, why is the USB outlet useless? Is it that there's no product that can take a USB digitization (whatever that is) of an audio signal and transmit it as bluetooth?
It's not that it needs to be put through a phono equalizer -- the audio would have to be equalized before being digitized for it to work with any recording program. I mean, an unequalized phono signal is about 20 dB down at 20 Hz and 20 dB up at 15 kHz (don't know the exact frequencies)! There's NO WAY you could just digitize that and send it to Audacity or a better recording program.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
