Main Screen

​
Level Meters

The PGM, REC, AUX, and VBUS meters display:
  • Average level in VU (slow-moving blue bar).
  • Peak level in dBFS (floating yellow segment).
The scale is calibrated in dBFS, where –20 dBFS corresponds to 0 VU.
The numeric value on the right shows the current maximum (in VU or dBFS) and toggles by tapping on the number.
The main meter remains visible on all screens and the bus can be changed by tapping the bus name on the left.
Note on levels:
The meters display the bus level.
  • On digital outputs, the level matches the output level when gain is set to 0.
  • On analog outputs, 0 VU = –20 dBFS, with nominal levels of +4 dBu (balanced) and 0 dBu (unbalanced).
    If a gain level higher than nominal is set, the headroom is reduced and clipping may occur before the meter indicates it.

​
CUE Level

Displays the CUE bus level, after the physical level knob.
