I was seeing this:
Main Out -12 dB
Whenever the device (e.g. mixing desk or audio interface) connected to the MAIN OUTPUT XLR or TS jacks indicates too much level coming from the PROFILER, or there is the need to set the Main Output Volume to less than -12 dB, then activate the Main Output Pad to reduce the signal level of the Main Output by 12 dB. This increases the range of the Main Output Volume control and preserves the signal-to-noise ratio of the Main Output.
I normally run around -14 so I tried this as recommended and had to run the knob up quite a bit. I didn't hear a big difference, and I don't hear of many people using this so I put it back to where it was. If I am running -14 should I really be using this button as recommended?
