1. Introduction
1.1 General
Thank you for purchasing Hall Research’s SC-HD-2A. This unit can convert
and scale DVI or HDMI video in to various output resolutions. Video can be
manipulated is several ways. For example, the output can be horizontally
flipped (mirrored along x-axis), or hue, saturation, and other salient
parameters of video can be manipulated. The mirroring feature is useful for
teleprompter and rear projection systems.
The unit takes advantage of the HDMI signal's ability to embed audio with
video. For convenience, both stereo analog and optical digital audio inputs
and outputs are provided. The audio from the input HDMI signal can be
extracted (de-embedded) and output on both digital as well as stereo analog
signal. The audio embedded in the HDMI output can be selected from 3
sources: HDMI input, analog L/R input, or digital optical input.
The SC-HD-2A has the ability to output a wide range of resolutions
regardless of the input timing and resolution. The output resolution can
automatically match the native resolution of the display connected to its
output (based on the EDID setting of the display), or it can be specified by
the user.
The SC-HD-2A features an OSD menu for configuration, picture setup,
system information and other advanced options. The compact and sturdy
enclosure features integrated mounting brackets.
1.2 Features
•Any PC or HDTV video signal can be scaled up or down to any other
PC or HDTV resolution

2. Installation
2.1 Connections
The SC-HD-2A accepts HDMI or DVI inputs and outputs. Video cables are
not provided, and for use with DVI equipment, adapter or HDMI to DVI cable
would be required.
The unit accepts audio input signal from TOSLink (optical) or analog (L/R)
that can be embedded it on HDMI output. The Audio signal that is in the
HDMI output is also extracted (de embedded) and available simultaneously
as TOSLink (optical) or analog (L/R).

* The NATIVE output setting causes the scaler to select an output resolution that
matches the native resolution of the connected display. In this mode, if the native
resolution of the connected display is not a supported output format of the SC-HD-2A,
then the scaler will output a 720p signal.
3.3 Setting the Output Resolution
As shipped from the factory, or after a factory default reset, the output
resolution is set to“NATIVE”. This means that upon power up the device will
read the EDID of your display and output a compatible resolution resulting in
a picture. However, if the output is set at a resolution not supported by the
connected TV, then you may not get a picture. This is a problem since
settings are done via on-screen display (OSD) menus.
3.3.1 Obtaining an image on the screen
To allow the user to get an image on the screen, two preset button
combinations are available on the front panel with very common resolutions,
one of which should produce an image.
1. If the display is HDTV (with an HDMI connection); then a resolution
of 720p should result in an image.
2. If the display is PC compatible (DVI), then XGA (1024x768) should
produce an image.
Once you have an image, you can call up the OSD menu to make further
changes as necessary.
Setting Resolution using Quick Select buttons
At any time, press the UP ARROW  and MENU buttons together to
directly set the output resolution to 1024x768 @ 60 Hz.
Press the MENU and DOWN ARROW  together to set the output
resolution to 720P @ 60 Hz.

Factory defaults may be recalled via (2) methods:
3.3.2 Recalling Factory Defaults
1. Press the MENU button to display the OSD. Using the  arrows
buttons, move to highlight the ‘FACTORY RESET’ option and press the
MENU button. The unit will reset all parameters to the factory defaults.
The output resolution will be set at ‘NATIVE’, which should result in a
picture being displayed. The actual resolution of the display monitor in
this mode is dependant on the monitor and not the SC-HD-2A.
2. Press and hold the UP ARROW and DOWN ARROW button
simultaneously for 3 seconds. This causes all parameters to revert to factory
defaults.
Press the MENU button to open the OSD and use the arrow buttons ()to
select the OUTPUT option. Press the MENU button.
3.3.3 Setting the output resolution
Use arrows to scroll thru the available resolutions listed. See Section 6 below
for a list of all available resolutions.
Default output resolution after a factory reset of the SC-HD-2A is “Native”.
4. Troubleshooting
There are no field serviceable parts or circuits in the device. If you think the
device is malfunctioning (or you have no picture output), please try to use the
methods described in Section 3.3 to obtain a picture first.
4.1 Contacting Hall Research
If you determine that your SC-HD-2A is malfunctioning, do not attempt to
repair the unit. Instead, contact Hall Research Technical Support at 714-641-
6607. To return the unit to Hall Research you must first get a Return
Authorization (RMA) number. Package the unit carefully, if returning. We
recommend that you use the original container.
