General Description

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 right (lower) section shows general keys.

Please note:
The specific keys that are displayed in the left (upper) Control Bar section can be defined individually for each instrument. To do this, touch the "Edit Instrument" key and select the "Configure Keys" option in the menu. The default value for each key can be set in the menu as well.

Instrument Description

Based on the functionality of the Surround Sound Analyzer, the ISA - Immersive Sound Analyzer displays all relevant technical and subjective parameters of immersive surround formats like 5.1.2, 5.1.4 7.1.2 or 7.1.4 in a fast and easy readable way. The graphical display has been carefully designed so that the dynamic behaviour of all display elements corresponds to the subjective listening impression, showing the balance of the surround program intuitively and at a glance not only in a layer but also in its spatial expansion.
Immersive surround formats normally consist of a Main Bed with the 5.1 or 7.1 part and an Upper Bed with the 2.0 or 4.0 part. The respective layer-related total volumes resp. the ambient signal are shown with cyan- and orange-colored lines of Total Volume Indicators (TVI) similar to the Surround Sound Analyzer. The spreading of the lines give feedback about the volume and the phase relations between the channels.
A Dominance Indicator (DMI as cross-hair pointer) can be added to every layer or bed, and an Immersive Dominance Indicator (IDI as variable white dot) across the layers. While the DMIs display the respective subjective sensed acoustical focal point inside of one layer, the position and the size of the IDI moving between the cross-hair pointers represent the perceived position of the spatial dominant focal point (height of the signal) of the overall sound field. A decreasing point and its approach to the cyan-colored cross-hair pointer indicates the moving of the focal point to the Main Bed. A big point near to the orange-colored and turned cross-hair pointer allows conclusions to be drawn about the volume relations between the layers or beds.
For the evaluation of the phase relationship between the channel pairs, correlators and Phantom Source Indicators (PSI) can alternately be displayed for one of the layers.

Control Bar - left (upper) section: ISA instrument functions

With the ISA instrument in focus, the left (upper) section of the Control Bar may contain any or all of the keys described below.

Please note:
Using the "Configure Keys" option in the ISA Menu, any key available for the ISA instrument may be removed from the Control Bar. Only keys set to "On" (default) in the Control Bar section of the "ISA Key Settings" menu are available in normal display mode with the ISA instrument in focus.

• PSI
This key is used to switch the phantom source indicators of the ISA instrument showing the position and width of phantom sound sources of the layer selected with the corrsponding key. The colors of the lines show the phase correlation of the adjacent channels (green: positive range, yellow: "0" range, red: negative range).

• COR
This key is used to switch the additional phase correlation meters of the layer selected with the corrsponding key.

• Layer Middle/Top
This key has toggle function with the switching states "Middle" and "Top". It is used to select the respective layer.
When "Middle" is selected, the keys of the Control Bar control the functions of the Main Bed (middle layer).
When "Top" is selected, the keys of the Control Bar control the functions of the Upper Bed (top layer).

• LFE
This key is used to activate or deactivate the additional warning display "LFE Phase!". This warning lights up in the lower section of the SSA, if the correlation between any channel and the LFE channel turns to negativ values.

• DMI
This key is used to switch the indicator (cross-hair pointer) for the position of the dominant sound event (dominance vector - subjective sensed acoustic focal point) of the layer selected with the corrsponding key.

• IDI
This key is used to switch the indicator (variable point) for the position of the spatial dominant acoustic focal point (height of the signal) of the overall sound field.

Control Bar - right (lower) section

The right (lower) section of the Control Bar always contains the following four keys:

• Edit Instrument
This key is used to directly access the menu parameters of the focused instrument. Any edits in the menu are saved to the current preset using the "Save" key.

• Load Preset
This key is used to load one of the presets stored in the unit’s internal memory or on an USB storage medium connected to one of the USB ports.

• Menu
This key is used to enter the Main Menu. This is the starting point for global system configuration, licence handling and preset management.

• Help
This key is used to enter the onscreen help for normal display mode (this text). Depending on the focused instrument, the help page will also describe the individual keys of this instrument.
