Using the 6200 for Mastering
6200 can be a useful tool for mastering applications in the professional audio industry,
such as preparation of equalized, level-controlled, peak limited CD masters. We have
frequently used the 6200 in this context, achieving excellent results.
Because of their broadcast origins, most of the 6200’s presets provide more processing
than would ordinarily be required for mastering. In addition, we would expect that the
mastering engineer would want to carefully tweak a preset to complement the program
material being mastered.
You can’t create a preset “from scratch”; it must always be modified from an existing
preset. Each preset has an “easy adjustment” facility called
LESS-MORE
, which is a one-
knob provision for turning the amount of processing up or down.
