The STC-3 is a spatial expander used to expand or narrow a perceived stereo field.
It is a natural sounding effect, designed to receive a stereophonic input and provide an either wider or narrower stereo output.
It does not use any artificial means of mono-to-stereo or stereo like effects and does not use active-phasing or delays to achieve its natural sounding result. A dedicated compensation mechanism keeps the ‘phantom center’ pure and natural sounding, while the stereo content is processed.
STC-3 is designed to be used on a single (stereophonic) channel or as a bus processor for full range processing, for either mixing or mastering. For such use, the dedicated LF processor becomes very handy and useful.
