Subclass Title
1/00 Two-channel systems (H04S 5/00, H04S 7/00 take precedence)
3/00 Systems employing more than two channels, e.g. quadraphonic (H04S 5/00, H04S 7/00 take precedence)
3/02 Systems employing more than two channels, e.g. quadraphonic (H04S 5/00, H04S 7/00 take precedence) of the matrix type, i.e. in which input signals are combined algebraically, e.g. after having been phase shifted with respect to each other
5/00 Pseudo-stereo systems, e.g. in which additional channel signals are derived from monophonic signals by means of phase shifting, time delay or reverberation (arrangements for producing a reverberation or echo sound G10K 15/08)
5/02 Pseudo-stereo systems, e.g. in which additional channel signals are derived from monophonic signals by means of phase shifting, time delay or reverberation (arrangements for producing a reverberation or echo sound G10K 15/08) of the pseudo four-channel type, e.g. in which rear channel signals are derived from two-channel stereo signals
