15. When would you adjust the gain setting rather than volume?
    • I have my gain setting on high and use the volume to control the audio output from aero to max. High setting gives you a higher output. I think the gain setting is to adjust for different headphones used with this player. Headphone impedance can range from 8 ohms to 64 ohms. The 8 ohms would be louder at the same gain setting as 64 ohms.
