Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The references to 'phantom' in case you did not already know, means 'phantom power'.
Which means, of course, providing power to the microphone through the microphone cord, for those microphones that contain power-consuming active circuitry.
I think that 4ch is what you need for true Four-Channel recording, for sure.
But tell me a little more about the situation, why you are uncertain as to 4ch meaning 4-channel ? or what 'false' 4-channel recording might be?
