channel sound field.

OThe built-in QS regular matrix system 4channel de-
coder decodes 4-channel records and tapes encoded
with the regular matrix system such as the Q5 system,
and their broadcasts, to reproduce them as a pérfect
4-channel sound field.

own front-back logic, decodes records and tapes en-
coded with the SQ system to properly reproduce them
in 4-channel stereo.

lator makes it possible to reproduce CD-4 4-channel
records, with increased inter-channel separation.

record/playback circuits. The 4-channel front inputs can
be in exactly the same manner as 2-channel inputs, for
either ordinary 2-Channel reproduction or 4-channel

circuit.
