Vintage The Fisher DR-14 CD-4 Disc Demodulator, fully tested and working.An unusual piece of early-1970s quadraphonic audio history, the DR-14 was designed specifically for playback of CD-4 / Quadradisc discrete four-channel vinyl records.Unlike matrix-based quadraphonic systems such as SQ and QS, CD-4 was designed to retrieve four discrete audio channels from specially encoded records. The DR-14 receives the signal from a compatible turntable/cartridge and demodulates the CD-4 information into separate front-left, front-right, rear-left and rear-right channels for connection to a four-channel audio system.The Fisher DR-14 was introduced around 1973 and is closely related to the JVC 4DD-5, one of the best-known standalone CD-4 demodulators of the period. Contemporary audio publications announced the Fisher DR-14 in 1973 at an original retail price of approximately $120.

Fisher is an American hi-fi name founded in 1945 in New York by Avery Fisher. In the vacuum-tube and early stereo era, The Fisher Radio Corporation built a strong reputation for carefully engineered, high-quality home audio gear and helped define what “hi-fi” meant to serious listeners in the 1950s and 1960s.
Historically, Fisher’s core products were amplifiers, receivers, tuners, and other home audio electronics rather than modern lifestyle categories like headphones, DACs, or cables. The brand was especially associated with tube amplifiers and stereo receivers, along with related components that brought higher-fidelity sound into mainstream living rooms.
Today, Fisher is best understood as a vintage-collector and heritage hi-fi brand rather than a current high-end market leader. Its classic equipment is respected among enthusiasts for its sound quality, build, and historical importance, while the brand itself has long since moved away from its original position as a premium American audio manufacturer.
