Record Volume Low on Playback

[Dino1956]

I'm new to this so I tested a recording. My Mic is all the way up in Levels. When I play back the Recording I hear it very faint that I can barely hear it. No matter how hot I put the Record volume, it's the same all the time. I'm not playing with anyone. I just started. I'm trying first to set levels & test things out. Watched all the videos of setting up Audio Gear, Network etc. I have both channels of my Mackie Onyx Black Jack interface set up for Inputs & Outputs 1 & 2. I see the meters and they are hot and in the red. But I hear almost nothing when I play back the recording. I went into Mixer and made those levels hot also. No difference.
