The LD100 Control panel
Selecting a push button control lights the adjacent
LED to indicate activation or selection of that partic-
ular function.
1) Power ON/OFF – Press the button and the LED
lights green to indicate POWER ON. When the
LD100 powers up it is automatically set to oper-
ate just as it was when it was last turned off. The
Detail Enhancement circuits are automatically
engaged at turn on.
1) Power ON/OFF - OFF – Another push on the
switch and the power is cut off extinguishing the
green LED. The Freeze Circuit is automatically
disengaged, if in use, upon turn off.
INPUT SELECTION SWITCHES (4)
2) Video – refers to any composite NTSC video
input - (e.g. VCR’s, laserdisc players, cable
boxes, etc.) Press to select the Video input.
3) Y/C – Y/C refers to any Super-VHS (S-VHS or
Hi-8) inputs - (e.g. laserdisc players, S-VHS or
Hi-8 video tape recorders, satellite receivers, etc.)
Press to select the Y/C input. Using the Y/C input
on the LD100 allows one to realize all the benefits
of maintaining the separation of the luminance
(picture) and chrominance (color) signal through
the video signal processing chain, thus avoiding
rainbow patterns due to cross color interference.
4) RGB – RGB refers to the incoming video signal
being broken down to the individual red, green
and blue format more typically found in the pro-
fessional and broadcast area. The most common
4) use of this input is computers (running at 15.75
kHz). Press to select the RGB video input.
5) Component Input – Component Inputs are
more commonly used in the broadcast studio or
post-production environment. The video signal
in its component form (Y, R-Y, B-Y) is carried in
a 3-wire cable with BNC type connectors (e.g.
MII™, D1, Betacam™, Betacam SP™, etc.).
Press to select the Component video input.
PICTURE CONTROLS (4)
The four rotary-style picture controls, BRIGHT-
NESS, CONTRAST, COLOR and TINT, are factory
preset when pushed in. When pulled out they
become active for manual adjustment. Pushing the
knob back in after manual adjustment gives you the
opportunity to compare your setting to the factory
preset(s).
The rotary control format allows for a high degree of
tactile feedback when one is adjusting the picture
functions. Additionally, these controls provide a
wider range of adjustment than those typically found
on monitors and televisions.
In addition, automatic chroma level and phase con-
trols (ACC and APC) are provided. As a conse-
quence, all source-to-source variations in chroma
phase and level are corrected.
When the signal is fed to a monitor through the RGB
inputs the monitor color and tint controls are
typically bypassed. Incorporating the LD100 in such
a system, with its broad range controls, restores
and enhances this control flexibility.

LINE DOUBLER OPERATING INSTRUCTIONS
For reasons of clarity, this technical overview has been written specifically for the LD100. This description
applies as well to the LD100U, with the following exceptions:
1. The LD100U accepts PAL and NTSC signals and switches automatically to the proper standard.
2. Tint control is not operational with PAL sources.
