HINTS FROM A SOU-NpENGINEER
PROJECTION
SOUIVD
Acoustics oI the Proiection
Room
Besides the suitability
for motion picture
screenj-ngs and the comfort i-t offers
to the audience, the projecti-on room must afso have good acoustics. The
best
results
will be obtained in a room in which reverberation
has been sui-tably reduced. A certain degree of reverberation
is nevertheless useful, since j-t tends
to rrliven uptr the reproductlon of the sould, especially
of music.
Reverberation
i-s produced by the mixlng of the soimd waves coming 4irectly
from
the speaker and of those that have been reflected
by ffoors,
l+alis, ceir1ng etc.
and which are heard as a nild echo.
Curtains of heavy materiaf will do much to alter the acoustic characteristics
of
a roomr to make thera suitable and to prevent the occurence of echoes
that interfere with good reproductlon.
Panels of sound absorbent material
can also be used
with good results.
Do not forget that an empty room has more pronor.mced reverberation than one that is fitled
to capacity.
-
Arranqement of Projector
and Spe.akers
The ideaf solution is to install
the projector
in its own separate booth, rn
this case, the auxiliary
speaker BE-14 (rf r.) is used" in the auditorium, while
the speaker placed- in the projector
1id is used by the operator for nonitoring
purposes' the speakers being regulated with the special speaker distributor
box
control.
If this arrangenent proves to be impractical,
th; projector may be set
up in the auditoriumr
preferably
behind the audience rather than in the nlddle
of it'
to avoid distraction
of attention
by the noise of the projector.
The projector can a.l-sobe set up in an adjoining room, provided
therl j-i a door or
other opening conveniently located to permit projeetion
from one room to the
other,
when the projector
is set up in the auditorium,
ei-tirer one or hnih
be used. the main speaker i-s best placed as near as possible i.n tlro
si-de or beneath it, but not too low.

microphones are less suitable,
because they pick up backgz'o'.md noises. In orOei to
avoid the recording of noises that would be detrimental

the

but at a distance oi several

a good view of the screen, without which proper synchronization
of sound and image
would be impossible.
Another more practical
solution is to record the narration first
on a tape recorder,
and then to transfer
it onto the film,
rarith or without dubbed_in musical accompani_
ment. To dub i-n the- mY-s1c, the output from the tape recorcier must be fed
to the phono

In this case, only one person is needed to make the recorcing. If
the sormd consists
of a mixed output from various channels, the operator must keep a check on
the relative levels by monitoring
the amplifier
output with earphones, nc matter which system
of recording is used.

in addition to top quality sound projection all the features required for
professionalsound recording.
The Bolex Proiectors
S-211and S-221
offer you the five most
importantfeatures:
1. Hi-Fidelitysound
2. Superb image quality
3. Utmost reliability
4. Greatest film
,protection
5. Ease of operation
1.
Hi-Fidelity
soundbecause...
Sound heads, amplifier, loudspeaker and
mechanical components were designed
for each other as a unit, according to the
most exacting specifications. Exceltent
sound quality is due to absolirtely coRstant
film movement assured by two massive,
perfectly balanced flywheels.
a) Optical sound head. lts carefuldesignyields
a faithfulreproductionof music,voiceand sound
effects.
- Frequencyrange: 50 to 7,000 c/s r 3 db.
- H i g h p r e c i s i o ns c a n n e r .
- Standard4 V 0.75amp.exciterlampfed by 40,0O0
c/s high f requency current, which eliminates
hum.The lampis precentered
and easyto change.
- Large ph.cto-electric
cell with elasticsuspension,
shieldedagainstmicrophoniceffects.
- Focusingknob keepsscannerbeamat maximum
efficiency. regardlessof whether emulsion or
base side of film faces sound head.
- Scannershieldedagainststray light from
valves
and other light sources.
b) Amplifier. Of sturdy construction,it was designedspeciallywith the useof a sound projector
in mind (choice of first class materials,modern
valves, silicium rectifiers).The wiring has to
undergo careful testing and the performances
are measuredto meet exactspecifications.
- F r e q u e n c yr a n g e : 3 0 - 1 6 , 0 0 0c / s , + 1 d b .
Audio power output : 15 watts, sufficienteven
for large auditoriums;
audio power output 3 % distorsion: 12 watts.
- Voltageselector.
- Two high impedanceinputs: 1) for microphone
;
2) for record-player,
tape recorderor radio.
- Two independantinput channel controls for
mixing and transitionalfades.
- Two output channels: 1 for loudspeaker

Volume control.
Tone control for bass and treble respectively
(responsecharacteristic
can thus be varied depending on the acousticalcharacteristics
of the
room where projectiontakes place).

Use of the amplifier as "Public Address"
system. Usedin conjunctionwith a microphone,
record-playeror tape,recorderthe amplifierloudspeakersystem can also serveas a public
addresssystem.
During proiection : to add commentary,background musicand sound elfectsto a silentfilm,
or to accompanythe music track of a lilm with
live narration:
Without projection : as a public address
system.
c) Built-in loudspeaker. Permanentlyfitted into
the projectorcover.
-Output:6watts.
- Diameter:8inch.
- Suppliedwith 50 foot cable.

Superbimagequalitybecause...
Paillard engineers have found ingenious
solutions to the four crucial problems that
face every designer of proiectors ; picture
brightness, definition, steadiness of image
and freedom from fticker.
a ) The high picture brightness, togetherwith
an even distributionof the light on the screen,
was achievedby creatingoneof thefinestopticalmechanicalsystemsto be found in projectors.
Its componentsare :
Sphericalreflector.
Condensersystem consisting of three coated
lenses.
Projectorlens of high aperture.

d) Flicker is eliminated with the built-in variable
shutter, which by the touch of a button can be
set for two or three blade positions, according to
the power of the lamp, projection rate,image size,
quality of screen and condition of the film.
Shutter adjustment can be made regardless of
whether projector is running or not.

Utmostreliability
because...
The sound proiectors
5-211 and 5-221
show infinite care in every component, the
observance of microscopic tolerances and
a carefully planned design down to the
minutest detail. Materials of chosen quality guarantee heavy duty performance. The
main components are permanently adjusted. All projectors have to pass exhaustive
tests during and after assembly.
Here are three specific, significant examptes of care in production and main parts

The film gate and pressureplatehaveto be corrected,machined,polishedand mountedwith the
highestdegreeof accuracyjustifiedby the limited
depth of focus of fast projection lenses.

Greatestfilm protection because...
Films, especially originals, are valuable
and often irreplaceable documents. With
this in mind. Eolcr enginaers have developed numerous foltures designed to
greatly lengthen the life of your film.
Here are some of thes€ featu?es :
Tension on film remains constant throughout
projection - in lorward, reverse and rewind regardlessof load on lake-uo reel.
Sprocketsand guide rollerstouch neitherframe
nor sound track.
Framegateand pressure
platearehighlypolished
and preciselypositioned.Easyto clean.
Claw mechanismis precisiondesignedto protect

stainlesssteel,machinedwith extremeaccuracv
a n d p o l i s h e dt o a s u p e r - f i n i s h .
Film,duringrun throughprojector,follows minimum of curvesand loops,
Moderate rewind speed protects film against
damagedue to excessivefriction.
The claw is slighlly raised before it leaves the perforation
to make sure that it does not scratch against the edge of
the oerforations.
As an exampleevery projectorhas to pass the
lollowingtest : a heavilysplicedtestf ilm is passed
repeatedlythrough the projector,both forward
and reverse,the film, on thorough inspection,
should not show the slightestsign of damage.
otherwisethe projectorwill not be admittedfor
shipment.
One basic principle at Paillard-Bolex is
safety combined with precision.

Easeof operationbecause...
b) Film threading becomes a matter of
seconds
- Lens holderswings out completely;leavingfilm
gate clear.
- Film is positionedautomaticallyon claw when
lens holderswings back to pro.iectionposition.
- ThreadingIilm into sound head is equallyeasy.
Tensionon film is adjustedautomatically.
The S-211 and S-221 are "compact" proiection machlnes in a single "suit case".
Although both projectors offer the latest
in technical refinement their operation is
easy and quiet.
c) Operating the proiector
- Foroperatingconvenience
