Kodak EKTAGRAPHIC 470 - Manual (Page 19)

Using a KODAK EC
Remote Control with
an EKTAGRAPHIC
AudioViewer/Projector
A KODAK EC-1, EC-2, or EC-3 Re­
mote Control (normally intended for
use with KODAK EKTAGRAPHIC
III and EKTAGRAPHIC Slide Pro­
jectors) can be connected to the re­
mote-control outlet of an Audio­
Viewer/Projector and used to
remotely advance and reverse the
tray. (The EC Remote Control can
also be used to record slide-advance
pulses when using the Models 270,
470, or 570AF).
If the KODAK EC Remote Control
has a focus switch, it can be used to
pause and restart the program tape
during recording and playback and to
record program-pause signals (with
Models 470 and 570AF). (The focus
switch on the EC Remote Control will
not provide remote-focus capability.)
Accidentally pressing the focus
switch on the EC Remote Control in
both directions while recording a pro­
gram-pause signal on the tape may
record an improper signal.
SPECIFICATIONS
Weight (approximate)—22 pounds
(10 kilograms)
Built-In Viewing Screen—9 x 9 in.
(229 X 229 mm); 12.1 in. (305 mm)
corner to corner; recessed to resist
impact; acrylic coated to minimize
glare.
Magnification Ratio of Built-In
Viewing Screen—7.15 with the
77 mm lens; 10.5 with the 56 mm lens.
Power Requirements—120 V
± 10%, 60 Hz, 300 VA maximum,
2.2 A.
Power Cord—three-wire grounded,
8-ft., permanently attached.
Projection Lamp—ANSI Code
DDM (19 V, 80 W) tungsten halogen.
At HI (17.5 V nominal) average lamp
life is 125 hours. At LO (14.5 V nomi­
nal) average lamp life is 1200 hours.
Rated lamp life is approximate.
Optional Projection Lamp—ANSI
Code DDS (21 V, 80 W) tungsten
halogen. At HI, life expectancy is 5000
hours.
OPTICAL SYSTEM
Projection of Transparency
Formats
The EKTAGRAPHIC AudioViewer/
Projector can project any transparen­
cy format in the rear-screen or front-
projection mode in a 2 X 2-inch (50 x
50 mm) mount, including 127-size,
126-size, 135-size, and 110-size trans­
parencies in 2 X 2-inch mounts or
KODAK 2x2 Adapters for 110 Slides.
The usable picture area for most
slide transparency formats will over­
fill the built-in viewing screen. In
front-screen projection, the full pic­
ture area of all transparency formats
(with the exception of 38 x 38 mm
super slides that are vignetted when
used with the short focal-length lens)
will be projected without image
cropping.

EKTAGRAPHIC AudioViewer/
Projector and EKTAGRAPHIC (or
CAROUSEL) Slide Projector
Image Sizes
When using the 77 mm //3.5 normal
lens in the AudioViewer/Projector,
the front-projected image will be
almost exactly the same size as
with the same slide type in
an EKTAGRAPHIC or CAROUSEL
Slide Projector, when the
EKTANAR, 3-inch (76 mm) //3.5 Pro­
jection Lens is being used.
With the 56 mm //3.0 image-magni­
fying lens, the image from the Audio­
Viewer/Projector will be about one
third larger (i.e., if the image is three
feet wide with the 77 mm //3.5 lens, it
will be about 49 inches wide with the
56 mm //3.0 lens). As a result, the
image area is increased by about
50 percent.
Normal Lens (Front-Projection
and Rear-Viewing Flat-Field
Lens)—77 mm //3.5.
Image-Magnifying Lens (Front-
Projection and Rear-Screen
Viewing)—56 mm //3.0 lens for short
projection distances and close-ups.
Mirrors—Mirrors to fold the light
beam and to give correct image orien­
tation are first-surface aluminized
with a silicon-monoxide, hard-surface
coating.
Focus Knob—Both the front and
rear lens and the image-magnifying
lens are focused by the manual focus
knob.
ELECTRONICS
Signal-to-Noise Ratio—35 dB mini­
mum at rated output.
Earphone (EAR) Outlet—1 W RMS
continuous sine wave into 8 ohms;
requires 1/4-inch (6.35 mm) plug.
Amplifier Power Output (External
Loudspeaker Outlet)—5 W RMS
continuous sine wave into 8 ohms
with maximum harmonic distortion of
5 percent.
Internal Loudspeaker—3 x 5-inch
(76
X
127 mm), 8-ohm, oval, base-
mounted, omnidirectional.
Audio Recording Indicator—Red
flickering light indicates that tape
tracks 1 and 2 for audio are in the
recording mode.
Signal-Recording Indicator—Illu­
minated green signal light indicates
that signal tracks 3 and 4 for 1000 Hz
slide-advance pulses (and 150 Hz pro-
gram-pause signals for Model 470 and
Model 570AF) are in the recording
mode.
