Important Note! The explanation of the Audio Processor functions and their respective parameters will be
done for the 5.1 + 2 program configuration. The 4 x2 values are a subset and may contain less functions
(e.g. no upmix is available in that mode) but if necessary both configurations will be explained.

Latency Mode
For non audio signals which may be appear at the input of a program
chain permanently or time by time you can select the behavior here.
[OFF / ON / AUTO]
[OFF / ON / AUTO]
[OFF / ON / AUTO]
[OFF / ON / AUTO]
You may force the DSP to pass through the audio stream untouched
in case there is encoded audio present. The AUTO mode is triggered
by the AES channel status.

In order to meet the regulations of
regions or countries you must select the
loudness control mode here. Beside of
the weighting curves several
measurement duration and loudness
ranges have bee defined. Some
regulations are based on the same
measurement (e.g. ITU BS.1770-2) but
defined in a different regional norm. You
must check with your local authority for
correct settings if you must comply with
regulations.
[ON / OFF]
You may turn the bypass ON/OFF from
here by activating the check box.
The bypass functionality may be
configured at the EVENTS >Actions
pane where the link will direct you to.
In a latency critical environment it might
be desirable to have the lowest possible
latency. So it is useful to actually bypass
a process that is not in use. In normal
operation, switching audio processing
modules on and off does not result in a
change of latency and thus does not
cause audible glitches or clicks.
Display of the actual latency. This
example has turned upmix on for
program 1. I.e. program 2 is
compensated so both have 40+ ms.
[Minimal / Compensated]
"horizontal" compensation for one
program. Disabled audio processing
blocks are taken out of the processing
chain and are no longer causing a
delay. However switching blocks on or
off can cause clicks and glitches, even
in unaffected channels, as the latency
compensation is recalculated.
