When is the Apple Camera Adapter necessary?
I understand that the Apple Camera Adapter is necessary to connect an iOS device to a DAC with a USB-B input. (iOS —> camera adapter —> USB-A to USB-B cable—> DAC) But is the adapter necessary if the DAC has a USB-A input? For example, if I have a DAC that has an USB-A input, can I plug in an iOS device with the same lightning to USB cord that I use to charge it? (iOS —> Lightning to USB-A cord —> DAC) Or does the Camera Adapter do something to allow the DAC to extract the digital audio signal? I’ve looked on other websites such as iFi Audio and they are rather ambiguous about this subject. Thanks for the help!
