Q: How do you choose line level out?

So for the dock connector it says you cab choose headphone out or line level out with iOS 7 or later.  Anyone know how this get line level to work?  I only have headphone out so the iPhone volume affects the stereo volume. 

 

Apple documentation is far from helpful. 

iPhone 7, iOS 10.0.2

    For the 30-pin iPhones, there are adapters that take the line out from a couple of the pins and run it to a 3.5 mm plug.

     

    For the Lighting Port iPhones, the Lightning Port exports digital audio, which seems like would be the line level you're looking for.

     

    Is that what you're asking about?

    Nope.  Audio Line Out should be an non-amplified audio source (AUX) to connect to an amplied stereo.  This eliminates the issue of the iPhone audio volume affecting the stereo volume.  Additionally the signal is much cleaner since it does not pass through the internal amp of the iPhone. 

     

    True LIne Out has always been an option on the Apple dock connectors up until the lightning dock connector.  Apple's documentation even states that the dock can do both with iOS 7 or later but does not explain how.  Apple support said the document is incorrect.   Trying to find out the truth...

     

    Bluetooth is not an acceptable option for audio quality for me. I can hold my phone and attenuate the Bluetooth signal enough for it to skip, the quality also is subpar.  AUX input is far superior, I would like to simply connect the phone and set the volume on the stereo and NOT have to adjust the iPhone volume as well.

    How would an input do that?
