Vista 1 Digital Mixing System
Response Time
3-54 Parameters
The response can be set from 20 ms up to 4 s. Recommended setting is 50 ms
but the engineer's ears have to decide. The response time cannot be compared
with release and attack times of dynamic processes. This time sets how fast
the crossfades between the calculated gain values are executed and how fast
VistaMix is reacting on the occurring changes of the signals.
Pan Mode The pan mode parameter defines where the PAN values of the individual
contributing channels are calculated. This applies for stereo VistaMix master
channels only (on mono VistaMix masters this parameter is automatically
blanked).
Normally dialogue is kept pretty central or even mono, so this is not an issue.
If however significant panning of the source channels is applied, then moving
the source channel pan function may change the acoustic effect of VistaMix
operation. Depending on the amounts of panning, there is a compromise
between dialogue moving and background noise and spill changing.
Initial settings from the comparison table below are recommended. But some
own experimenting will do no harm, and the final decision is up to the engi-
neer's ears.
