BT signal cleanliness


Recommended Posts

I just got my first Bluetooth head unit (pioneer). I’m just curious what volume level I should set my phone to (iPhone 7) to avoid clipping while playing iTunes.  Not running any amps right now and don’t have a dd1, just curious if someone has tested that the phone is clean all the way up or if it varies from model to model? TIA

Not 100% sure for bluetooth, but my previous iPhones were clean up to four clicks down from max via Aux (3.5mm) cable, tested via DD-1.

the Bluetooth on my pioneer  clipped at 38 our of 42 on my head unit, as did everything else on it. but im sure that it is different per head unit. I would set it at around 75-80 percent of units max volume, the issue with blue tooth is your S/N ratio drops and is more inherent to noise, I would just test your RCA voltage as this usually clips one or two steps after the speakers and just make sure its not going over what your rated and as soon as it does dial it back one or two notches its going to be all guessing until you get a DD-1 or DMrta / oscope .

Thanks for the responses folks, I appreciate the input. Once I get the system started and amps in I will get in touch with my contact who does have a DD1, so should find out for sure at that point.
