What's the best way to put a headphone splitter (also known as an amplifier) (say the PreSonus HP4 Discrete 4-Channel Headphone Amp) out of an audio interface (say the Universal Audio Volt 2):

  • Out of the headphone output.
  • Or out of the monitor outputs.
  • This is really 3 different but related questions. The first two can arguably be answered together as they are closely related, but the final one is pretty independent and should be asked as a separate question.

The input on the HP4 appears to be a line input, so monitor output would be preferable unless you specifically need something that only the headphone output can do.
