touch hot surfaces .
6. If an extension
cord is necessary, a cord with a suitable
current rating should be used. Cords rated for less ampe-
rage than the appliance may overheat . Care should be
taken to
arrange the cord so that it will not be tripped
over or pulled.

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.)

Sound Options
• Extension Speakers
Adaptor (SC- 00 2) Cord
• When using E lmo exte nsion speakers, (Twin
two-wa y or ES-650), conn ect the speaker line
to E XT . SP. connector .
• When adapting your own extension speaker,
the optiona l SC- 002 adaptor cord with 6¢
jack can be used for connecting a speaker line
with EXT. SP. connector.
Note: 1. Be sure to use speakers with an imp eda nce rating of 8 ohms.
2. Be careful not to s hort the speaker circuit. If shorted by accident, a
circuit
prote .ctive device cuts off the power to th e amplifier a utom at ically.
I
n s uch a case, unplug the p owe r cord and leave it as it is for 20 to 30
seco nds. By doing so , the amplifier can be r estored .
