Multichannel active matrix sound reproduction with maximum lateral separation

Disposed on the directional code to two sound channel (92,94) stereo audio signal translations part is at most the output sound channel (172,174,176,178, LS, poles) signal sound system for reproducing to four-track quadraphonics or the sound ways which comprises a decrypt device, is used to increase; the user uplink signal input reversing device code reducing track the intensities in the signal, and a nothing is connected with the code direction; and at same side of biggest degrees of dissociation and input sound channel non-directional coding component and energy each output sound channel between the sound rail, a to record in the input sound channel the musical is located in the outputting the sound channel program of sound channel, it on theThe musical is arranged on left input sound channel wherein the left sound channel program . Moreover the musical instruments' the apparent of the output sound rail rattles how, regardless of the input signal directional code element direction of invariable.
