Fail Over 2L/2R
switch that provides an independent stereo fail over circuit
Mode the switch may be permanently [FIX]
connected with either the Downmix, 2L/2R or
the AUX input but may also perform an
[AUTO] switch over from the first input to the
alternative input.
Fail Threshold (dBFS)
[-60 … -40]
Fail Wait (s) [1.5 … 10.0]
Fail Return (s) [0.0 … 10.0]
Side Chain Filter [OFF / ON] see Fail Over Upmix at previous page
Surround Detect to perform an automatic upmix in case the
main surround signal fails.
Switch the surround switch may be permanently
[FIX] connected with the surround input or the
upmix output but it may also perform an
[AUTO] switch over in case the surround
input fails.
Detection here you can decide which channels must be
observed for signal loss to operate the
surround switch. This switch is independent
from the upmix state! You are able to feed
the 1L/1R output even if the upmix is not
activated either by "Upmix Enable=Off"
or by "Fail Over Upmix=AUTO no upmix"
setting of that switch.
Signal Loss=All channels are gone.
Fail Threshold (dBFS) [-80 … -40]
Fail Wait (s) [0.0 … 10.0]
Upmix
Enable [ON / OFF]
Profile [Balanced / Front Projection]
Upmix Mode Tells the algorithm if the input signal may have correlated components
or not [stereo / mono].
Process [slow / mid / fast]
reaction time of the upmix processes. For news, sports, shows with
permanently changing content (e.g. applause) setting "fast" is
recommended while mid / slow is recommended for music, movies.
Processing Time (ms) [3 … 100]
the Look-Ahead Delay has great influence on the quality of the upmix
process in regard to the latency of the process. The more time you
have to analyze the stereo signal the better the result for the upmix
signal will be. Depending on the system latency requirements (ingest
vs. live broadcast) you may change the processing time accordingly.
.
Center Divergence [0.0 … 1.0]
the upmix process assembles a center signal from the input stereo.
It may either be fed to the center channel only (0.0) or spread
between L/C/R (1.0). The effect will be a wider presentation of center
signals in a surround sound image.
