Nakamichi High Com
II



The culmination of joint Nakamichi and Telefunken
research, High-Com II is the world's finest two-band audiophile noise
reduction system.



This highly sophisticated unit employs
a two band design with advanced High-Com compander ICs for 20 dB
noise reduction throughout the entire audio band. Dynamic range is
greatly expanded, without the sonic coloration, breathing, and
distortion that plague conventional audiophile companders. Can be
used with discs, also.

Hard to find a better one.

High-Com II and
III

Nakamichi one of the more than 25 licensees of the High Com system, supported
the development of a noise reduction system that could exceed the
capabilities of the then-prevalent Dolby B-type system. However, it
became apparent that a single-band compander without sliding-band
technology, which was protected by Dolby patents, suffered too many
audible artifacts so, High Com was further developed into the
two-band High Com II and three-band High Com III
systems by Werner Scholz and Ernst F. Schröder of
Telefunken assisted by Harron K. Appleman of Nakamichi in
1978/1979.

The two-band variant was eventually released exclusively as
Nakamichi High-Com II Noise Reduction System later in
1979, increasing the amount of noise reduction on analogue recordings
and transmissions by as much as 25 dB A-weighted

High-Com II
for vinyl

While originally designed for tape recordings, Nakamichi
demonstrated the usage of High Com II on vinyl records
as well in 1979.

In 1982, the same AEG-Telefunken team, who designed the High Com
noise reduction system, also developed the IC for the CBS Labratories
CX noise reduction system for vinyl records, a system also
incorporated into FMX, a noise reduction system for FM Broadcasting
developed by CBS.

High Com FM

Similar to the earlier Dolby FM system in the US, a High Com
FM system was evaluated in Germany between July 1979 and
December 1981 by IRT. It was also considered to be adopted for
AM broadcasting based on the High Com broadband compander, the
system was field-trialed in public FM broadcasting between 1981 and
1984. However, despite the improvements it was eventually not
introduced commercially because of the listening artifacts it created
for receivers without expander.
