Can I increase the bluetooth signal on an apple iPhone 7?
I am using a bluetooth receiver to play music from my apple music subscription through my older, traditional A/V audio system. I am finding that the bluetooth signal from my iPhone 7 is not strong enough to have the volume that I want from my Yamaha R-S300 audio receiver system with 4 Klipsch speakers, two floor standing, and two bookshelf. I would like to improve on the bluetooth signal to make the sound stronger and more audible. The bluetooth receiver is a good one with it's own "Wolfson" DAC. Is there any adjustment I can make on the iPhone to make the bluetooth signal stronger? Or maybe a change in the setup to accommodate the large size of the stereo system?
Any suggestion are very much appreciated.
iPhone 7, iOS 12
