The T 10 Projector was introduced in 1956 as a
totally new concept. This blue-coloured projector
was fitted with, at that time, a very modern 12 V 100
W projection bulb. It has only one speed, namely 16
frames/sec and it is suitable for only one voltage. All
the projectors of the T 10 series came with a plastic
dust hood, which could be used as a projection table.
Because of this design, it was possible to construct a
smaller projector suitable for 120 m reels. This pro-
jector is also suitable for combining with a tape
recorder. The receiver of the electric signal is built
into the projector. This beautiful but more expensive
electric system was not used after the T 12 series. It
was, however, to continue to be found in a Russian
projector.
Bauer T 10 Projector
Three different models were offered for the sound system. First was the Tonkoppler K 1, a simple,
tape-recorder driven, round disc, which delivered its information to the projector and could add
music to the movie.

It was however, better to use the TZ 31 for speech if lip synchronisation was desired. The TZ 31
has one + and one – button. If, during the projection of the movie, the picture is not in synch, one
of the buttons could be pushed to correct the problem. The TZ changed its name to Tonkoppler
N.
The TZ 30, later called S, became a culminating point of sound registration at that time. It was
for tape speeds of 9.5 cm/sec and 19 cm/sec. The model was provided with a switch for
converting reproduction via the projector to recording via
the movie camera. There is also a potentiometer for adjust-
ing running qualities of the movie camera as well as a
signal lamp to indicate when the camera and the projector
are in synch. There is a switch contact for the recorder with
remote control and help buttons for projection. Bauer
pointed out the pure synchronisation of this system in their
advertisements. The maximal deviation in the synchroni-
sation is ¼ picture = 1/64 sec. This means that, with the TZ
30 + camera and the TZ 30 + projector, great deviation
would be prevented, and any discord would come from an
advance or delay of only 1/32 of a second, approximately
half of a picture frame by a speed of 16 frames/sec. Quite TZ 30 Sound Recorder
an achievement!
If you make such an apparatus, then there must be an appro-
priate sound camera as well. It is the 88 E equipped with a
synchronization contact, which is connected with the TZ 30
by means of 6 meter metre long cable. This device was called
88 ES. The 88 E is also provided with a turret, like the 88 D
and a combination of the 88 ES and the 88 D became the 88
DS.
