NOTED AT PHOTOKINA

stir and brought exclamations ot delight
from those who have deplored the fact
that there has not been, up until now, a
truly professional piece of editing equip¬
ment designed to handle Super-8 film
for double-system sound cutting.
The Super-8 console is so new that
there was no literature or technical data
available on it at Photokina. However, it
looks almost identical to the Steenbeck
Model ST 1600, and a company repre¬
sentative on the spot verified the fact
that, except for its Super-8 picture
format, the new machine is very similar
in technical characteristics to its 16mm
picture counterpart.

new recorder. The device operates on
the indirect-control principle and makes
possible the transfer of Pilotone record¬
ings onto perforated tape with mains
operation.
An
important feature of this
synchronizer is mains independent play¬
back operation together with a batteryoperated Arriflex camera equipped with
Pilotone. In this mode of operation, the
Arrivox-Tandberg recorder powers the
synchronizer. When accumulators are
used in the tape recorder, the synchroni¬
zer serves as battery charger.
A comprehensive report on the new
Arrivox-Tandberg recorder and syn¬
chronizer will appear in an early issue of
this journal.

New Version of the PERFECTONE
Model EP 6A II Recorder

AR R IVOX-TANDBERG Sync-sound
Magnetic Tape Recorder Introduced
An important "first" at Photokina
was the introduction of the new Arrivox-Tandberg portable battery-operated
tape recorder, the result of a joint
development in which both ARNOLD &
RICHTER (manufacturers of Arriflex
cameras) and TANDBERGS RADIOFABRIKK of Norway combined their
experience in the application and design
of professional tape recorders for
synchronous operation with motion pic¬
ture cameras.
The new Arrivox-Tandberg recorder
(described by an on-the-spot company
representative as "an instrument of the
highest quality, but in the middle price
range") takes into consideration the
special requirements of synchronous
operation in combination with Arriflex
cameras and functions with dry cells,
accumulators, or with external power
supplies. Other motion picture cameras
equipped with Pilotone generator can,
of course, also be used in conjunction
with the Arrivox-Tandberg recorder.

ARRI and TANDBERG engineers
have also put their heads together to
create a special synchronizer for the
1200

Introduced at Photokina by PER¬
FECTONE was a significantly rede¬
signed version of its familiar Model
EP 6A II %-inch professional tape re¬
corder. It is a silicium transistorized unit
for portable and self-contained, cordless
"lip sync" motion picture sound re¬
cording.
The tape deck unit, together with the
controls and interconnections have not
been modified but the electronics have
been completely redesigned using the
latest semiconductor techniques. The
use of silicon transistors and diodes
throughout has improved the perfor¬
mance especially for dynamic range and
distortion, whilst at the same time
providing increased temperature stabili¬
ty in severe climatic conditions.
The wide choice of pilot tone
synchronisation together with the two
mixable microphone inputs and 2 watt
monitor/output amplifier makes the
Perfectone EP 6A II S ideal as sound
recorder for 16mm and 35mm films.
The new model is finished in a
two-tone royal blue and light grey semimatt enamel.

Recording on a pulse head of an
internal local or external pilot tone
frequency, using the Perfectone system
with two edge or centre tracks.
Pilot tone signal replay for control of
the Synchro Tape synchroniser.
A possibility to fit an internal crystal
oscillator 50, 100 or 60 Hz for record¬
ing a reference frequency. This system
allows recording in perfect synchronisa¬
tion with a crystal controlled camera
without interconnection cables.
The possibility to connect the Per¬
fectone Synchro Tape synchroniser for
transfer onto perforated film and for
synchronous playback.
Selection of the operating modes by
means of a push button unit on the
control panel.
The motor speed is maintained at a
strictly controlled speed by a centrifugal
regulator and a transistor motor current
switch.
Fast rewind by auxiliary motor. Tape
spool diameter 12.8 cm (5").
Operating speed 19.05 cm/sec (7.5").
This being only professional standard
for portable recorders.
Power supply using 12 1.5 V bat¬
teries or 12 rechargeable 1.2 V accumu¬
lators providing 18 V or 14.4V respec¬
tively.
Operating time 12 hours for batteries
8 hours with rechargeable accumulators
per charge.

General Characteristics
Recording with 2 microphone inputs
or 1 microphone and 1600 ohm line
input.
Simultaneous recording and replay.
Recording of the audio on a central
track 4.8mm wide leaving the 2 edge
tracks for a separate synchronisation
signal. This system allows a reduction of
crosstalk between the synchro signal
and audio modulation to better than
60 db.

HALO 6000 Halogen Discharge Lamp
A compact, lightweight unit that
gives a Brute arc a run for its money,
the HALO 6000 represents a new devel¬
opment in the field of halogen discharge
lamps.
The luminaire itself weighs only 11
pounds and it has its own power supply
