^{* -} Phone output is additional, for high quality sound use RCA with external head amplifier. If use Phone output don't forget to enable the digital volume control in your player.

^** - Using with cellular phone or tablet will quickly discharge it's battery, so using external power supply is recommended. Also if you want to use very long (>1.5m) USB cable.

ATDAC-8 power consumption is about 0.55A, which is a little bit more then the regular USB port provides according to the standard. But I never seen USB port, not satisfied ATDAC-8 with it's current, at least with the short (<0.5m) USB cable.

However, it is better to us USB cable as short as possible. Also not use very thin USB cables ("Chinese no-name").

^*** - External power supply requirements: 5VDC ^{(+0.5, -0.2V)}, 0.6A at least
