In display mode, the TouchMonitor shows the instruments and their layout defined in the currently loaded preset.
Touching the screen area of an instrument will put this instrument into focus. This is recognized by a colored frame instead of a grey one. The frame color conforms to the identifier set for the group the focused instrument belongs to.
The Control Bar positioned at the lower screen edge contains several keys. It is displayed permanently if the "Control Bar" option in the "General" section of the "System" menu is set to "permanent". Otherwise, it will be displayed temporarily after touching the screen.
The Control Bar has two sections. The left (upper) section shows the specific keys defined for the focused instrument. This makes it very fast to access a specific function of one of the instruments on screen – just touch the instrument and select the desired function.
The Radar instrument displays momentary loudness and loudness history in a single, unique Radar view. The circular, color-coded display makes it easy to balance audio visually and to see when level falls below or exceeds the end-listener's loudness range tolerance.
The moving outer ring of the instrument represents the Momentary loudness value changing its color to orange when passing the Target Level (displayed at the "twelve o'clock" position). The area inside of this ring showing concentric circles is called Radar view and represents the Shortterm loudness history. There, the Target Level is marked with a thick circle deviding the Radar view into a Soft part (all values inside the Targel level circle) and a Loud part (all values outside of the Target level circle).
It is a tremendous help for a mixing engineer or a video editor to know which radar area to stay inside. For example, film sound may fall outside the normal broadcast expectations.
The radar is complemented by a true-peak warning and by two descriptors to characterize the entire loudness ‘landscape’ of a program, film or music track precisely.
By default, the numbers displayed are program loudness and loudness range:

Program loudness is a standardized integrating loudness measurement. If one program should be aligned in loudness with another using only a gain offset, that offset would be the difference between the program loudness values of the two. Practically speaking, both programs should simply be normalized to a certain target loudness. In the United States, the value to aim for is -24 LUFS. That number is directly compatible with AC3's dialnorm parameter, which should also be set to 24. |

Loudness range is a standardized measure of the loudness range of a program. It measures the difference between soft and loud parts. From an application's point of view, loudness range is compelling 1) as a production guideline, 2) for prediction of platform compliance during ingest or on a server and 3) for verifying a transparent signal path all the way from the studio to the home-listener. Note that the number stays the same downstream of production, even if a program is later normalized. |

With the Radar instrument in focus, the left (upper) section of the Control Bar may contain any or all of the keys described below.
The right (lower) section of the Control Bar always contains the following four keys:
