PRODUCT DESCRIPTION
LinkBridge 18G/4K HDMI Scaler with Audio Insertion & Extraction User Manual (LB-H2SCL)
The LB-H2SCL Scaler accepts and outputs a wide range of resolutions up to 4K@60Hz (4:4:4,
8-bit) with simultaneous audio embedding and de-embedding of digital (HDMI or optical) or
analog audio. Integrated EDID and HDCP management options allow for control over the way
connected sources and displays detect the unit. The scaled HDMI output is powered by a
high quality single-pass scaling engine with the ability to adjust the image with a number of
fine tuning options including: contrast, brightness, hue, saturation, sharpness, noise reduction,
and RGB levels. 3-D motion adaptive de-interlacing and frame rate conversion is supported
as well.
The HDMI input and output supports passing up to LPCM 7.1 digital audio as well as Bitstream
and HD Bitstream audio formats. Audio embedding and de-embedding is also available with
the included digital optical and analog stereo audio inputs and outputs (LPCM 2.0 only).
Shortcut keys are provided to quickly change the output resolution to 1080p@60Hz or XGA
when needed for quick connection to a display or for troubleshooting purposes.
This is an ideal device to integrate previously incompatible sources and displays in your
boardroom, classroom, or home. This unit is controlled via a comprehensive On-Screen
Display (OSD) menu that provides the user with easy access to all settings.

1. OUTPUT: SELECTS THE OUTPUT RESOLUTION TO
USE. SELECTING “NATIVE” WILL MAKE THE UNIT AUTO
MATICALLY SELECT AN OUTPUT RESOLUTION BASED ON
THE DETECTED EDID OF THE CONNECTED DISPLAY.
2. ASPECT: SELECTS THE ASPECT RATIO TO USE WHEN OUT
PUTTING THE SOURCE. “FULL” STRETCHES THE SOURCE TO FILL
THE OUTPUT RESOLUTION, REGARDLESS OF THE ORIGINAL AS
PECT RATIO, WHILE “BEST FIT” WILL ALWAYS ATTEMPT TO RETAIN
THE ORIGINAL SOURCE’S CORRECT ASPECT RATIO BY ADDING
BLACK BARS IF NECESSARY. “FOLLOW IN” CENTERS THE SOURCE
ON THE SCREEN, WITHOUT ANY SCALING 1:1 PIXEL REPRODUC
TION. SELECTING “ZOOM MODE” ACTIVATES THE FREESCALING
ZOOM MODE WHICH ALLOWS FOR A ZOOM/SHRINK LEVEL TO BE
MANUALLY SELECTED USING THE “ZOOM MODE RATIO” SETTING.
NOTE: SOME VIDEO NOISE MIGHT BE PRESENT WHEN US
ING THE “FOLLOW IN” MODE IF THE SELECTED OUTPUT
RESOLUTION IS 4096×2160@60HZ AND THE SOURCE IS
AT, OR ABOVE, 1680×1050 BUT BELOW 3840×2160.
3. ZOOM MODE RATIO: SETS THE PERCENTAGE AMOUNT TO
ZOOM OR SHRINK THE IMAGE WHEN “ZOOM MODE” IS ACTIVE.
4. HDCP: SELECTS THE HDCP LOGIC TO USE WITH
THE HDMI INPUT. SETTING THIS TO “OFF” WILL COM
PLETELY DISABLE HDCP SUPPORT ON THAT INPUT.
5. NO SIGNAL COLOR: SELECTS THE FREE RUN COL
OR TO USE WHEN NO LIVE INPUT SOURCE IS DETECTED.
6. BLANK: ALLOWS FOR THE OUTPUT VID
EO AND AUDIO TO BE BLANKED/ MUTED.
7. FREEZE: ALLOWS FOR THE OUTPUT VID
EO TO BE FROZEN. WHILE THE OUTPUT IS FRO
ZEN, AUDIO OUTPUT WILL ALSO BE MUTED.
1. Output: Selects the output resolution to use. Selecting “Native” will make the
unit automatically select an output resolution based on the detected EDID
of the connected display.
2. Aspect: Selects the aspect ratio to use when outputting the source. “Full”
stretches the source to fill the output resolution, regardless of the original
aspect ratio, while “Best Fit” will always attempt to retain the original
source’s correct aspect ratio by adding black bars if necessary. “Follow
In” centers the source on the screen, without any scaling (1:1 pixel
reproduction). Selecting “Zoom Mode” activates the free-scaling zoom
mode which allows for a zoom/shrink level to be manually selected using
the “Zoom Mode Ratio” setting.
Note: Some video noise might be present when using the “Follow In” mode if the selected
output resolution is 4096×2160@60Hz and the source is at, or above, 1680×1050 but
below 3840×2160.
3. Zoom Mode Ratio: Sets the percentage amount to zoom or shrink the image when
“Zoom Mode” is active.
4. HDCP: Selects the HDCP logic to use with the HDMI input. Setting this to “O”
will completely disable HDCP support on that input.
5. No Signal Color: Selects the free run color to use when no live input source is
detected.
6. Blank: Allows for the output video and audio to be blanked/ muted.
7. Freeze: Allows for the output video to be frozen. While the output is frozen, audio
output will also be muted.
8. Auto Sync O: Sets the amount of time to continue outputting sync with the free run
color if there is no live source and no operations have been executed
on the unit. Setting this to “OFF” forces the unit to always output sync.
9. Output Setting: Allows for configuring the following special video signal handing
functions.
