In 1970 the World Exhibition took place in Osaka, Japan, and for this occasion 50 Bauer projectors were
ordered which, in combination with 2 Bauer U 3 machines, made it possible to perform an impressive
multivision show. The Siemens Rototonsystem took care of the synchronisation between the projectors.

The third generation P6 projectors were released in 1971. They were now supplied with a 20 W, later 25
W, amplifier and a four-claw movement, which no other 16 mm projector had. This P6 projector could
handle virtually any film, no matter what its condition. Also in 1972 some sound projectors were supplied
with a stop button that made still projection possible.

At the same time a two-tone P6 Studio system was released. On this there were two sets of reel arms so
that the perforated 16 mm sound tape on one was synchronised with the movie film on the other. A little
known machine is the P6 H. It was designed to cater to a demand from universities who needed the
option of changing quickly from one film to another for
teaching purposes. A projector that could be manually fed
was necessary in this case, which is why the P 6 H has no
automatic film load. The P6 H series consisted of the
models L, TS and MS, but commercially it was a disaster.
During this period the factory underwent major renova-
tions made necessary because production was running up
to a thousand projectors per month, while 16 mm projec-
tors accounted for around 20% of Bauer annual sales.
The P6 series had been on the market for over ten years
and so many technical changes had been made that the
sixth generation of projectors then in production looked
nothing like the early ones. It was a major problem for the
service technicians and it became time the projector was
given a new name: the P7. The main difference between
the P6 and the P7 is the colour. Except for the Marc-lamp
machine all models were supplied with the still projection
option and of course each machine has a four-tooth claw.
There are seven models:
P7 for silent films.
P7 L for films with optical sound.
P7 TS for films with optical and magnetic sound.
P7 MS like the TS but can also record magnetic sound.
P7 M Synchron. This projector is a special model for use in sound studios.

The essential constant speed was created thanks to a con-
denser- synchromotor, which allowed the choice of 24 or 25
images per second. To be able to record on a magnetic border
track the projector was supplied with a smart switch, a mod-
ulation meter and an interlock to prevent erasing by accident.
An advantage for working in a studio, where a small screen
was mainly used, was the reducible light output. Also, this
machine was suitable for TV studios because it could be
connected to a video camera as well as a multiplexer to mix
with other image sources.

P7 T Universal 300. This machine was supplied with the
Marc high-pressure gas-discharge lamp, which has a four
times higher output than a halogen lamp. This is the machine
