PPM Digital resp. PPM True Peak Scale  

The "Scale" key in the "PPM Digital" resp. "PPM True Peak" section of the PPM menu is used to select the scale displayed in the PPM instrument. Depending on the individual scale selected, certain instrument parameters such as the reference level are switched as well. The most important parameters for each scale are listed below.

  

Please note:
The PPM instrument combines PPM and loudness bargraphs using various selectable bar arrangements. The scale used by the loudness bargraphs is set in the "Select Loudness" menu (Edit Current Preset >> Edit Group >> Loudness).

  

Please note:
On TMR7 Smart some scales are not available.
