PREPARING FOR PROJECTION
1. Connect the A. C. Cord of the projector to
th e household power supply and th e pilot
lamp will light simultaneously.
At the same
time the Projection Lamp
is being preheat-
ed
(F ig. 1).
2. Lift up the Front Reel
Arm (Fig. 2).
3. Set the
Main Switch to the Forward posi-
tion and the Projection Lamp will go
on
(Fig. 3).
4.
Aim the projector at th e screen and adjust '
th e height of the projector with the Ele-
vation Control. Next,
fill the screen with
the projected light be adjusting th e Zoom
Lens accordingly. Finally, adjust th e Hor i-
zontal Level Control if necessary (Fig. 4).
5. Return the Main Switch to
"Stop " (Fig. 5).
3

6. Attach the reels. The reel of film to be pro-
jected goes on the front, with the perfora-
tions on the right-hand side, and the empty
Take -up Reel is mounted on the Take -up
Reel Clip (Fig. 6).
* If the reel is correctly loaded, the film will
come
off the reel from the right-hand side.
If the film comes off the reel from the left-
hand side, the reel requires rewinding.
* The reels should lock in place when attached
to the Reel Arms.
If a reel does not secure-
ly lock in place, gently move the reel to and
fro to a ll ow the Reel Clip of the Reel Arm
to properly engage in the ree l.
7. To prepare your film for automatic thread-
ing, trim the leader of the film 3-4 mm by
using the Film Cutter, (supplied with the
projector) (Fig. 7).
SOUND PROJECTION
1. Set the Speed Selector to desired speed (18
or
24 fps) . Since 18 fps is normally used,
the Speed
Se lector shou ld be in the pro-
truding position (Fig. 8).
Projection speed can be
"fine tuned" to
make up for any variance in the power
supp
ly .
2. Set
the Main Switch to "THREAD"
(Fig. 9).
3. Insert the leader of the film into the Film
Gate entrance and the film will automat-
ically attach itself to the Take- up Reel within
5 seconds (Fig. 10).
* Do not remove the Main Switch from the
"THREAD" po sition until the film is
properly taken up onto the Take -up Reel.
4

*Use the special Take-up Reel wh ich comes
with yo
ur Chinon Sound 7500 Pr ojector.
4. Set the
Main Switch to the Forward posi-
tion to
turn on the Projection Lamp and
commence proj
ect ion of the film. (F ig. 11 ).
5. Adjust both the sharpness and the frame
line of the picture by turning the focusing
and fr aming co nt rols (Fig. 12).
6.
Ad ju st the sound volume by rotating the
Vo lume Control Knob and select the mo st
pl easing tone by adju st ing the Tone Control
Knob (Fig. 13).
If the pict ur e jumps when runnin g, turn
the Ma in Switch to "LOOP FORM", and
then reset it to the
"FO RW ARD" position.
SILENT PROJECTION
Use exactly the same procedure as for so und
projection, but without using the Sound Volume
Contro l. The Volume Control should be at
its minimum setting.
REVERSE PROJECTION
For amusing effects such as people and a ut o-
mo bil es moving ba ckwards, or a person jump -
ing out of the water and on
to a diving board,
reverse projection may be used.
To use, move
th e Main Switch to Reverse. Wh en set to this
reverse projection position, the
so und amplifier
will a
ut omatically be turned o ff, resulting in si-
le
nt projec ti on (Fig. 14).
REWINDING THE FILM
Wh en the film is over, rewind the film onto its
original reel
by following the procedure outlined
below.
5

1. Set the Main Switch to "Stop"
2. Insert the end of th e film into the slit of the
original reel
(Fig. 15), making sure the film
passes over the Rewind Roller.
The
film should be inserted into the slit from
the bottom so that the original reel can ro-
tate counterclockwise (when
th e control
panel faces you). .
3. Set the Main Switch to "REWIND"
(Fig. 16).
Wh en rewinding, the Speed Selector may
be set to 24 fps for a faster rewind.
EXTERNALLOU~SPEAKER
An exte rnal l ou d· speaker with a ma x imum
o utpu t of 12W (for the m odel to U.S .A. and
Canada, 15W for ot her co untri es) (twice
that of the loud speaker built-in to yo ur
so
und projector) may be co nn ec ted to the
pro j ector for eve n bett er so und qua li ty.
Mor eover, if the externa l lo ud speake r is
pl
aced n ear th e screen, highl y r ea li st ic
effects
are possible.
To use an external loud -s peaker, connect it to
the Loud-Speaker Jack
of the projector (Fig. 17).
• When using an external loud speaker,
other than
th at specia ll y designed for yo ur
Chinon Sound 7500 Projector, use a RCA
type (for the model to U.S.A. a nd
Ca nada, DIN Type for other co un tr ies)
jack adapter if n ecessary.
• Th e external loud -s peaker should have an
impedance
of 8- 16.0 . To avoid possible
damage to the amplifi
er of your sound pro-
jector, do not use a model with an imped-
ance
of less than 8n.
RECORDING
Before attempting to record, please read this
section carefu
ll y.

• Ordin arily, when th e Record Butt on is d e-
pressed, previously recorded material on th e
film will be erased, and only
th e new re-
corded material w
ill remain.
• Addi ti onal so und e ff ects or na rr a ti on c an
be added to the film during projec ti on with-
o
ut er as ing th e mat e ri al pre vi ously record-
ed
by using th e so und on so und system of
yo
ur pr ojector.
• Ordinary recording should fir st be m as tered
before attempting the more sophis
ti cated
technique of sound on so und recording.
AUTOMATIC OR MANUAL ADJUSTMENT
OF RECORDING LEVEL
• For beginners, it would be wise to set th e
Aut o/Manual Recording Level Control
Butt on to the Aut o (protrudin g) p os ition.
Wh en this is done, th e ALC (Aut omatic
Level Co
ntr ol) circuit will aut omatically
adjust low or high so un ds to th e co rr ect
level for success
ful recording.
• Ad va nced amate ur s will enjoy using th e
manual adjustme
nt of the recording level
in order to e
ff ect subtle changes or elimi-
nate backgro
und noise.
MIC JACK AND AUX JACK
• T he mi crophone is plugged into the Mic
Jack and used for recording na
rr a ti on, live
mu sic, or so und e ff ects. Th e microphone
should be he
ld away from the so und pr o-
jector to eliminate th e possibility of pi ck-
ing up noise.
• For noise- fr ee recording fr om a tape record-
er, ra
di o, or phonograph, co nn ect th e in-
s
trum e nt dir ec tl y to yo ur so un d projecto r' s
Aux Jack.

• For recording a narration without mistakes,
first record it on a tape recorder and then
co nnect the tape recorder to your projector.
RECORDING FOR THE FIRST TIME
B eg inners can practice on about 5 meters of film
(unexposed film may also be use d) .
WITH A MICROPHONE
1. Insert the microphone plug into the Mic
Jack of the projector (F ig. 18).
2. Set the Sound on Sound Knob to

RECORDING FROM A TAPE RECORDER
OR SIMILAR SOURCE
1. Plug the recording cord into the Aux Jack
of your Chinon Projector and the appropriate
jack (LINE OUT, MONI, EXT. SP.,etc.)
of your tape recorder, radio, or phonograph
(Fig. 29).
2. Since the output of tape recorders, radios,
and similar sources vary from model to
model, the Volume Control
of the external
source (e.g. tape recorder) should
be used
for adjusting volume. To do so, turn the
Main Switch to "Stop", plug in an earphone
and monitor by depressing the Record But-
ton. While monitoring, adjust the Volume
Control of the external source until the re-
cording level is sufficiently loud and clear.
The above applies when recording with the
Recording
Level Control set to AUTO.
When setting the Recording Level Control
to
MANUAL the following procedure
applies:
a) Set the Main Switch to "Stop".
b) Set the Volume Control of your Chinon
sound projector to the MIDWAY
pOint
(the 12:00 o'clock position).
c) Plug earphone into the Monitor Jack of
the projector.
d) Depress Record Button.
e) While monitoring, adjust the Volume
Control of the tape recorder, excercising
care that the indicator needle
of the
Recording Level Meter does not enter
the red zone of the scale (Fig. 30).
3. Rotate the Main Switch clockwise to the
Forward position (Fig. 31).
4. Reset the Record Button to the RECORD
(recessed) position (Fig. 32).
10

RECORDING DURING PROJECTION
The Record Button can be depressed, and re-
cording commenced, at any point during pro-
jection. Moreover, the Record Button can
be
instantly disengaged at any point during projec-
tion
by merely pushing it in once again.
ERASING
To erase a previously recorded film without re-
cording, proceed
as follows:
1. Disconnect the cord
of the microphone,
tape recorder, or other source from the
sound projector.
2. Set the Auto/Manual Recording Le
vel Con-
trol Button to the MANUAL (recesse d)
position (Fig. 33).
3. Rotate the Volume Control Knob complete-
ly counterclockwise (toward "LOW")
(Fig. 34).
4. Set the Sound on Sound
Kn ob to "NOR-
MAL". (Fig. 35).
5. Start the projector and depress the Record
Button (Fig. 36).
SOUND MIXING
A microphone and tape recorder can be connect-
ed to the sound projector
for simultaneous re-
cording
of a narration and background music,
for . ex ample. Of course, in such a case, care must
be taken that the background music does not
overpower the narration. For b
es t r es ults, pro-
ceed
as foll o ws:
1. Connect the tape recorder to the Aux
J
ac k, and the microphone to the Mic Jack
(Fig. 37).
II

2. Set the Sound on Sound Knob to "N OR -
MAL " (F i g. 38).
3. Adju st the volume of the tape recorder.
4. Start the tape recorder and begin the na rr a-
tion while monitoring with the earphone.
Readju
st the volume of the tape recorder,
if necessary, to bl end we ll with the narra-
ti on (F i g. 39).
5. Co
mm ence recording.
SIMPLE MIXING METHOD WITH ONE
MICROPHONE
Pl aya tape recorder as background music (w ith-
o
ut connecting it to the projector) and speak
int o the microphone for the narration. Th e
mu sic or narration can be emph as i ze d simply
by placing the mi crophone closer to one so ur ce
than the
ot he r. Although this is not a perfect
system and some background noise m ay be pi ck-
ed
up , the beginner may wi sh to start with such
a simple syste
m.
SOUND ON SOUND RECORDING
Th e so und on sound system is used to add nar-
ration, b ac kground mu sic, or so und e ff ects to a
film witho ut erasing the pr e vi ously recorded
mate ri a l. However, if one mak es a mi stake with
the so un d mat erial added to the o ri ginal record-
ing, the mistake can not be er as ed without si-
multaneously erasing the o
ri ginal recording.
Ther efore, careful practice is necessar y.
If th e o ri ginal recording level is very low
t
o. begin with, an additional recording may
cancel out the o
ri ginal, so exercise care.
If yo u record a narra ti on on a narration the
result may be gar
bl ed so that neither is un -
derstoo
d. Therefore, avo id such an attempt.
12

FOR SUCCESSFUL SOUND ON SOUND
RECORDING
FOllOW THE PROCEDURE
OUTLINED BELOW
1. Set the Auto/Manual Recording Level Con-
trol Button to the" AUTO" (protruding
position).
2. Move the Sound on Sound Knob complete-
ly co unt erclockwise (to the left) (F i g. 40 ).
3. Rotate the Main Switch clockwise to the
Forward position
(F ig. 41).
4. Depress the Record Button at the point in
the film where you wish to do sound on
sound recording.
Wh en this is done, the
original sound track will no lon ge r be heard
(F ig. 42).
5. Adjust the Sound on Sound Knob to a suit-
a
bl e recording level by slowly rotating the
knob clockwise. Norma
lly , setting the knob
to an approximate
ly 11:00 o' clock p os ition
will res
ul t in a favorable recording level;
to lower the level, rotate knob co
unt er-
clockwise. M ov ing the Sound on Sound
Kn ob to the ri ght (cl oc kwise) will result in
an increase in the recording level.
If the
knob is moved a
ll the way to the "NO R-
MAL " position, normal recording will
occ
ur , erasing the original recording and
leaving only the new recording
(F i g. 43).
6. Upon com
pl e ti on of sound on sound record-
in
g, rotate the So und on Sound Knob com-
pletely to the left and
di sengage the Record
Button. If the
So und on Sound Knob is then
reset to i
ts former positon, sound on sound
recording can be started again merely by
pushing in on the Record Button
(Fig. 44).
13

FADE-IN/FADE-OUT TECHNIQUE
To intersperse additional sound within the orig-
inal sound in a natural manner the following
Fade-in/Fade-out technique may
be employed:
1. Rotate the Sound on Sound Knob complete-
ly counterclockwise, and depress the Record
Button (Fig. 45).
2. Gently rotate the Sound on Sound
Knob
clockwise (with the additional sound source
connected to the projector) until it comes
to the
"NORMAL" position and continue
recording (erasing the original sound).
3. Next, when you wish to have the original
sound gradually
fade back in, rotate the
Sound on Sound Knob gently counterclock-
wise until it comes to a stop. This can
be
repeated to intersperse additional sound
within the original recording (Fig. 46).
THE LINE OUT JACK
When connecting the sound projector to an am-
plifier and external loud-speaker combination,
the
Line Out Jack is used. For copying the sound
track of your film, a tape recorder is plugged
into this jack. When using an external amplifier
and loud-speaker, proceed
as follows:
1. Connect the Line Out Jack of the projector
with the
AUX (Line In) jack of the exter-
nal amplifier (Fig. 47).
2. Connect the amplifier to the external speaker.
3. Adjust volume with the volume control of
the amplifier.
14

PAINPUTJACK
The PA Input Jack can serve three useful pur-
poses:
• The projector can be used as a public
address system
by plugging in the micro-
phone and adjusting the volume
of the
projector (Fig. 48).
• The microphone can be plugged into the
PA Input Jack and used for narration during
projection completely independent
of the
recording system.
• Silent movies can be made to come to life
by adding narration in the above manner,
or
by connecting a tape recorder for sound
effects. When a tape recorder is used, volume
should
be adj usted by the volume control
of the tape recorder (Fig. 49).
