In 1972, I formed Sigma Systems Engineering
to engage in the development, design, manufacture and sales of professional
mixers and other audio products for studio and remote broadcast
applications. Since then, we have pursued technical innovation under
the KAMESAN trade mark, symbolising our motto slow but steady
Together with NHK, Japan's national broadcasting company, as well
as private stations nationwide, we began to develop unique, custom
designed audio equipment for broadcast, which we also installed
for these customers.
In the past, equipment used for Japanese broadcasting tended to
be large, heavy and expensive relative to performance. We considered
this as a design challenge and by keeping our efforts focused on
this area, created compact, light and multi-function products to
At that time, equipment such as broadcast cameras was large and
heavy and had to be mounted on massive tripods. Then the revolutionarily
compact Betacam for broadcast was developed, making it possible
for a remote crew to shoulder a camera and move around. This in
turn led to requirements for light, compact and multi-function audio
equipment. We had also entered a period for audio innovation.
Our R&D capability was gradually increased and within 5 years,
we launched an extremely compact 3 channel audio mixer. It was the
first product of our own design and was rapidly accepted as an exceptionally
compact, light and multi-function audio mixer for broadcast. Today,
we proudly enjoy a large market share of Japan's portable mixer
market, which is in the region of over 95%.
With continual support from broadcast stations and more recently
formed production houses, we have introduced many new products which
are developed within the same design criteria and achieve steady
business. We have also gained very high credibility in the industry
which calls Sigma 'the company representing compactness' and the
company with the mark of Kamesan.
Having recently been alerted to production efficiency, we now undertake
product development with a broadened design concept which includes,
in addition to 'light and compact', time saving set up
and easier to work with when going on-air.
A good example is the product named the 'Commentary System'.
The Commentary System is powerful typically when broadcasting international
sports events which often take place in Japan nowadays. It's a remarkable
system from which you can conduct both program and talkback feeds
with commentators from multiple guest countries. For instance, Japan
hosted 100 guest countries for the Winter Olympic Games. The system
aims at reducing work and stress by providing broadcasting facilities
from the host station to each countrys booth as well as supporting
the host engineers efforts.
In 1990 we were fortunate to acquire a piece of land near Shinjuku
in Tokyo and built our head office there. We moved into the new
premises to work together more closely and respond to industry expectations,
that there is no other company but Sigma which leads audio for broadcast.
I believe our mission for the future should be to continue product
development reflecting our unique ideas and close customer ties,
an advantage which a larger company does not have, whilst making
