Thank you for selecting the Elmo ST·600D Sound Projector.
The Elmo
ST ·600D is a high performance sound projector capable
of magnetic recording and playback on two sound tracks as well
as playing back ready·made optical sound film (Model M·O).
What's more, this new sound projector features unlimited sound
recording potentials including, dubbing capabilities which enable
the buildup of the most sophisticated sound tracks in the most
effortless manner.
Be sure to carefully read through this instruction manual to make
the most
of these fascinating features and to ensure against improper
handling that may result in damage.

Track 1
(Main stripe)
INTRODUCTION
Two Track System
Track 2
(Balance stripe)
As shown in the above illustration, 8mm sound film comes striped
with magnetic coatings on both edges, also known as "magnetic stripe."
The wide or "main" stripe is used to carry the sound track when used in
conventional projectors. This sound stripe
will be called Track 1 here-
after in this manual.
The narrow or "balance" stripe, that runs just outside the film perfo-
rations,
is used for balance to ensure smooth film travel through the
projector.
Though Track 2 is narrow in width, it is coated with the same quality
magnetic oxide as that on Track 1. So, the Elmo ST-600D utilizes
both the main stripe and the balance stripe for recording and playback.
We have designated this new sound system a Two Track System.
After receiving your sync-sound film from the processing laboratory,
there will most likely be sound on Track 1.
Music and narration can be added to the balance track (Track 2) to
accompany your original sound on Track 1. You may record on
Track 2 as often as desired or until you are totally satisfied with
the mixed recording. This is done without affecting the original sound
on
Track 1.
[If the film does not come striped with a magnetic coating, it is
necessary to ask your nearest photo dealer to have your film striped
when sending
it in for processing.)

PROJECTION
Preparing For Projection
o Place the projector on a stable stand or table and face the projection l ens to
the scr een.
Note:
8
Be sure to use a firm stand. If the projector is mounted on an
unsteady s urf ace such as a thin-board box, a possible resonance may
develop causing poor pro j ection performance.
8 Plug the power cord.
oPull both reel arms up into position.
oPlace your film on the front arm and the
take-up reel on the rear arm. Press the reel
lock s until the reels are snug against the
spindles.
