Kodak 220 - Using External Controls; Technical Specifications Overview

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) — 2 2 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.
MagniHcation Ratio of Built-In
Viewing Screen — 7 .1 5 with the
77 mm lens; 10.5 with the 56 mm lens.
Power Requirements — 1 2 0 V
± 10%, 60 Hz, 300 VA maximum,
2.2 A.
Power Cord — t hree-wire grounded,
8-ft., permanently attached.
Projection Lamp — A NSI 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 — A NSI
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) f/S.b 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 ram //3.5 lens, it
will be about 49 inches wide with the
56 mm //S.O lens). As a result, the
image area is increased by about
50 percent.
Normal Lens (Front-Projection
and Rear-Vie wing Flat-Field
Lens) — 7 7 mm //3.5.
Image-Magnifying Lens (Front-
Projection and Rear-Screen
Viewing) — 5 6 mm //3.0 lens for short
projection distances and close-ups.
Mirrors — M irrors 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 — B oth the front and
rear lens and the image-magnifying
lens are focused by the manual focus
knob.
ELECTRONICS
Signal-to-Noise Ratio — 3 5 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 — R ed
flickering light indicates that tape
tracks 1 and 2 for audio are in the
recording mode.
Signal-Recording Indicator — I llu¬
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.
