PPM:
Peak Program Meter tracks the peaks of the audio content rather than the perceived loudness or the
power content of the material.
PPM with peak hold: (PPM peak)
The peak hold feature allows the user to keep track of the audio peak. A floating mark is pushed up by
audio peaks and is reset with either a programmed GPI input (see the section on "GPI, GPO and Text
Window Setup") or a menu command (see the "Clear Faults" menu).
VU:
Volume Unit meter follows, approximately, the perceived loudness of human hearing.
VU with peak hold: (VU peak)
The peak hold feature allows the user to keep track of the peak VU reading. A floating mark is pushed up
by audio VU peaks and is reset with either a programmed GPI input (see the section on "GPI, GPO and
Text Window Setup") or a menu command (see the "Clear Faults" menu).
VU with floating PPM: (VU PPM)
This mode displays both VU levels and PPM levels on the same bar graph. The VU level is indicated by
the solid bar going up and down, while the PPM reading is indicated by a floating white bar. The scale
displayed is a decibel scale with 0 corresponding to program reference level (for all modes except
AES/EBU).

This control sets the bar graph to one of five basic types. The ballistics
and display characteristics of the bar graphs are configured with other
items in this section of the menu structure.
