HOT TIP!

The nominal inputs levels for each input can be adjusted using the Ch "x" Gain option in the

2nd through 3rd AUDIO menus.

You can also enable phantom power for inputs 1 & 2 on AUDIO menu 8. Note that this

controls phantom power for both input 1 & 2 simultaneously.

HOT TIP!

The individual level of the audio for each of the 4 mixer inputs (post fader) can be monitored

on the first AUDIO menu (status screen). This permits seeing the ratio of the 4 inputs in the

mix shown on the main SEND bargraphs.

A visible clip indication is also provided. If clipping occurs, the word "Clip" will be

displayed for that channel. If clipping occurs you will need to change the Ch "x" Gain

setting for the input that is clipping.
