Abstract (en)
[origin: EP2709380A1] The system has separators adapted to receive left and right side components of a composite stereo signal. Sequence switches are adapted to distribute signals including one of right and left side components between combinations of central and lateral paths according to a preset distribution. The switches include filters to modify a directivity diagram restored on each lateral path to create a cancellation direction. The filters perform filtration while receiving one of the components based on pressure gradient. An enclosure (10) is presented outside in the form of a widened column.
