4ch SE decoder which included SE logic circuit in 4ch decoder and which was developed a component and for stereo sets.

The OTL power amplifier used for a rear channel is carried. For this reason, 4ch stereo can be enjoyed by using it for the usual stereo set.

It connects from the REC terminal of a stereo set, and the connection method connects an output to the Playback terminal of a rear speaker and a stereo set.

RM-SQ-QM-4 matrix is built in the decoder part and 4ch play of almost all the commercial records can be carried out.
