ND PROJECTOR
.
.
The magnificent Bolex 16 mm sound projector
is the result of many years of intensive research and a tradition of fine Swiss craftsmanship almost 150 years old.
Highly versatile, the Bolex 5-221 projects both optical and magnetic sound films, on single or double perforated
film. Simple controls make it easy to get highly professional results in recording sound effects, music, and narration
on striped films. A combination of superb quality construction and the latest technical advances make the 5-221
the ideal projector for discriminating amateurs, professionals, and specialists in education, science, and industry.
The Bolex S-221 Gives You Top Performance
On All Five Requirements
For Perfect Sound-Movie Projection
HIGH FIDELITY SOUND QUALITY
1
The sound head is as easy to thread as the projector itself,
and absolutely constant film movement through it is assured
by two massive, perfectly balanced flywheels. It is designed
for optimum reproduction of music, sound effects, and narration,
from both optical and magnetic sound tracks. Optical sound
reproduction has a frequency range from 50 to 7000 cycles
±
5 decibels; magnetic sound reproduction from 50 to 10,000
cycles,±5 decibels. The magnetic sound head can be used
for full, half, and quarter width tracks with no adjustment.

The precision amplifier has centrolized controls for easy
operation. A rugged, high fidelity unit, its 15 watt audio
power output makes it ideal for use in large auditoriums as
well as in smaller rooms.

supplied with a 50 foot extension cord, has a 6 watt power--
output, and is 8 inches in diameter.
SOUND HEADS
Optical sound head
has
standard 4 V, 0.75 amp. exciter
lamp fed by a 40,000 cycle
high frequency current, elimin-
ating all noise. The lamp is
extremely easy to change.
Adjustable focusing of the
accurately centered lightbeam
ensures maximum sound qual-
ity regardless of whether the
emulsion or base side faces
the sound head. Large sur-
face photoelectric cell. Opti-
cal sound system protected, sealed, and completely shielded
from ligllt from valves or other sources.
Magneticsoundhead
is ruggedly constructed for greatest
resistance f wear and tear. Erase head operates on a high
frequency magnetic field to assure complete erasure of pre-
viously recorCled souna. lhe erase head is located next to
the recording head for instant switching when required.
The wide range, simplicity of use and robust construction of
the sound"Unlf are another three highly appreciated advantages,
to add to the many already boasted by the S-221 projector.
AMPLlFIEJl
Accidental erasure of recorded
sound and other errors are
impossible because all controls
are centrally located and
include safety devices. Sepa-
rate volume controls for micro-
phone and pick-up, radio or
tape recorder; independent
tone controls for bass and
treble. A built-in mixer permits
professional results through the
combination of sound effects,
narration, and music. A neon
lamp provides a visual control for magnetic recording. Separate
aural control, by means of earphones, over sound quality and
volume. Voltage selector for maximum efficiency. High
impeCiance input channels for microphones, pick-up, radio, or
tape-recorder. 6 Ohm output channel for speaker and 50 Ohm
output for earphones.
The amplifier of the S-221 projector can be used in a public
address system and so allows one to give a commentary or
sound effects when projecting a silent film.

PICTURE QUALITY
A unique condenser-reflector system is built into the S-221 to
provide maximum brightness and equal light distribution.
Three fast projection lenses are available in 35, 50, and 75 mm
focal lengths. Each lens is composed of six elements and
conforms to the most rigid standards of optical precision.
Fully corrected for aberrations, these «HI-FI» lenses are you,
guarantee of perfect color and freedom from distortion.
The claw mechanism and film guides on the S-221 are made
to exacting tolerances to ensure absolute steadiness of the
projected image.
Picture flicker is completely eliminated because the shutter can
be regulated for two or three light interruptions per frame,
either while the projector is running or stopped. At any
projector speed, with the screen at any distance, pictures are
bright, sharp, and flicker free.
FILMS SAFEGUARDED
3
Every part of the Bolex S-221 that will touch your film has
been specially engineered to protect its perforations, surface,
and sound track.
Tension on the film remains constant from the beginning to
the end of the reel, in forward or reverse run in re-wind and
regardless of how full the take-up reel may be. '
The sprockets and guide rollers touch neither the frame nor
the sound track.
The film gate and pressure pad are highly polished and pre-
cisely positioned. Easy to clean because the lens holder swings
out completely.
The claw mechanism is precision designed to protect the per-
~ forotions:
~

of tearing.
The magnetic sound heads are aligned with extreme accuracy
and cannot damage the picture.
The optical sound drum is made from anti-magnetic, stainless
steel, polished to a high finish, and machined with extreme
accuracy.
Separate film paths for optical and magnetic sound so the
optical track cannot be damaged by the magnetic heads.
Even urn films can be projected without da~ger'

CONVENIENT TO USE
Streamlined and compact, the Bolex S-221 sets up easily in
seconds. The loudspeaker in the cover can be quickly detached
for location in another area of the room, and the projector height
adjusts instantly at the turn of large, convenient leg controls. A
table lamp can be connected to the machine for automatic on-off
operation.
Film is threaded in seconds through automatically closing sprocket
guides. The lens holder swings out a full 1800to eliminate
fumbling the film onto the claw mechanism. The film automatically
moves into position on the claw as the lens holder is returned to
projecting position. Tension on the film placed in the sound head
is adjusted automatically. No need to change the reels for
rewinding.
To simplify operation even more, all projector controls are
grouped in a panel on one side. Even in the dark, foolproof
projection is guaranteed because the control panel, stroboscope,
and watt meter are illuminated.
A centralized lubrication system makes maintenance easy and
quick.

DURABLE CONSTRUCTION
Everyone of the thousands of parts that comprise the Bolex S-221
is precision machined and carefully tested before final assembly.
As with all Bolex movie equipment, it takes many months of
painstaking work to complete a projector. Only the finest raw
materials are used, and they are chosen after careful consideration
of the particular function which the finished part will perform.
The drive mechanism, for example, is milled from extra hard,
chrome-plated, tempered steel, and the cam is milled to a tolerance
of 2/10,000 of an inch. Certain parts in the magnetic sound head
are made to a tolerance even greater than 1/10,000 of an inch.
The finished projector, as a result of this unhurried and precise
manufacturing, will give years of prime performance.
OPTICAL FEATURES
Standard 750 (code: BENGE)
or 1000 Watt (code: BERSO)
projection lamp is mounted on
hinged lcmphouse door for
most convenient changing.
Lamp current can be adjusted
and measured on built-in meter
to provide brightest picture
and longest lamp life.
Aspheric reflector and conden-
ser system has three coated
elements which can be cleaned
easily on both sides. Swing out
lens holder for easy cleaning
of film gate and aperture.
Framing is conveniently regulated with a knurled knob which
moves the film and does not disturb the centering of the image.
Lenses available include 35 mm f/1.3, code: SOPRO - 50 mm
f/l.3, code: SOCAN, and 70 mm f/1.6, SOSEP. The shutter
is adjustable in order to eliminate flicker while projecting.
MECHANICAL FEATURES
Universal type motor with high
starting torque. It runs silently,
has push button stop and three
position switch for reverse and
forward with or without lamp.
The speed is variable from 18 to
24 f.p.s. and is accurately stabi-
lized by a ~overnor activated by
electronic Impulses. A built- in
illuminated stroboscope shows n

speed. Built-inframe counter with manual zero setting automatically
shows every ten frames and can be read easily while the projector is
running. This is an invaluable aid when recording and a particular
part of the sound track must be picked out quickly and accurately.
