Compatible Discrete 4, also known as Quadradisc or CD-4 (not to be confused with compact disc) was as a discrete four-channel quadraphonic system for phonograph records. The system was created by JVC and RCA in 1971 and introduced in May 1972. Many recordings using this technology were released on LP during the 1970s. Other major record companies who adopted this format include A&M, Arista, Atlantic, Capricorn, Elektra, Fantasy, Nonesuch, Reprise and Warner Bros.

vintage panasonic se-405 cd-4 system disc demodulator.
The CD-4 demodulator sensed these high frequencies then converted them to a range of around 100 to 15,000 hertz. This is the odd man out in the quad world. Extremely ‘fine’ grooves were etched onto the vinyl record to provide frequencies between 35,000 and 50,000 hertz. The CD-4 demodulator sensed these high frequencies then converted them to a range of around 100 to 15,000 hertz. These frequencies were then sent to the amplifier and on to the rear channels.
