Mixing sound for houses of worship poses a unique set of challenges, particularly when large choirs, musical ensembles and multiple worship leaders are involved. These scenarios often require multiple open or active microphones, which leads to microphone spill, increased background noise and greater possibility of system feedback. As each active microphone 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.
HARMAN’s Studer VistaMix is a software upgrade for its range of Vista digital mixing consoles that offers a solution to these problems. VistaMix automatic microphone mixing 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 microphones of silent participants in order to reduce spill and background noise.
VistaMix offers the solution by mimicking the action of a human operator: increasing gain for ‘talking’ microphones 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 microphones that are in use. Several nested VistaMix groups can be set up so that individual areas can be managed separately and then combined.
This significant new feature is available to all existing Vista systems with SCore Live DSP engines and the Vista 1. By simply 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.
