unusual facts about High Com FM



Dolby noise-reduction system

A similar system named High Com FM was tested in Germany between July 1979 and December 1981 by IRT.

High Com

Besides Telefunken's own CN 750 High Com compander box and Nakamichi's High-Com II unit, other companies also offered external High Com compander boxes such as the Aiwa HR-7 and HR-50 or the Rotel RN-500 and RN-1000.

Nakamichi, one of the more than 20 licensees of the High Com system, insisted on using a sliding-band compander, so High Com was further developed into the two-band High Com II and three-band High Com III sliding-band 2:1:2 systems by Werner Scholz and Ernst F.

A low-cost implementation of the Telefunken High Com system as external compander box became available as HobbyCom, promoted for do-it-yourself assembly in the popular WDR TV series Hobbythek format by Jean Pütz in 1980.
