Audio Power Source Setting - Advantech PCM-5862E User Manual

Audio power source setting (J16)
The PCM-5862E/5862EL is designed to work with a single +5V
power supply. The audio interface can also function normally
under single +5V power supply, but most audio controllers require
an independent power source generated from a +12V power. The
independent power source avoids the noise from the other digital
circuits. The PCM-5862E/5862EL's audio interface can also
accept +12V power to provide improved quality audio. This is
done via J16.
