Justin, Et all, you do realize the SD mixer is showing analog VU scale with "0" as Unity on it meter, while the UM camera (and digital recorders) use a different "Digital dB" scale, where ""0" on the SD mixer equals about -18 on the camera digital scale, with average peaks set at -12, to get the necessary headroom before clipping occurs at digital "0" (which equals +18 on the SD, which is where the scale goes red. From 0 dB on the SD to +6 is where you want the actual audio levels to be at.
So set the camera level with the tone generator on (at 0dB on the mixer) to -18 on the camera meter, as a starting point and test it. If the audio sounds too noisy, reduce gain on the camera to -20, the. Test again. Every camera/recorder is a little different in the scales their meters use. When recording, the camera should be hitting peaks at around -12, which will be around +6 on the SD mixer. Hope this helps
