Studer VistaMix Upgrade Offers Automatic Microphone Mixing Solution

Particularly well-suited for house of worship applications

Studer VistaMix is a new software upgrade for the range of Vista digital mixing consoles, offering automatic microphone mixing that removes the need for an operator to manually adjust all the faders all the time, leaving the microphones of talking participants open while closing the mics of silent participants in order to reduce spill and background noise.

Mixing sound for houses of worship in particular can pose a unique set of challenges, particularly when services involve large choirs, musical ensembles and multiple worship leaders.

These scenarios feature multiple open or active mics, which leads to microphone spill, increased background noise and greater possibility of system feedback. As each active mic is added to the mix, intelligibility decreases while unpleasant comb filter effects (phase distortion) become more common.

Manual fader control can miss cues when speakers speak unexpectedly, plus changes in fader positions can quickly lead to disturbing changes of the total ambience/noise level in the mix.

VistaMix offers the solution by mimicking the action of a human operator: increasing gain for “talking” mics and reducing gain for all others, but doing it very quickly and keeping the amount of total gain constant, so a clean live mix can be created.

In addition, VistaMix switches on only those mics that are in use. Several nested VistaMix groups can be set up so that individual areas can be managed separately and then combined.

This new feature is available to all existing Vista systems with SCore Live DSP engines and the Vista 1. By upgrading to software version 4.9 and adding the special VistaMix channels to the DSP configuration, VistaMix is ready to go. No additional hardware is required to the Vista surface, the new controls are fully implemented within the standard Vistonics screens and controls.
