1.0 Introduction

The SC-12BT is a 12 input HD scaler that accommodates 4 HDMI, 4 VGA,
and 4 AV inputs.

Select any of the inputs by using the front panel push-buttons, IR, RS-232, or
IP commands. The selected source is scaled to a fixed user definable
resolution and simultaneously output in 3 convenient formats: VGA, HDMI,
and HDBaseT (class B for easy extension to 70m / 230ft on a single UTP
connection using compatible receivers or displays with built-in HDBaseT
inputs).

The SC-12BT provides comprehensive audio capabilities. HDMI audio is
extracted; VGA and AV inputs (Composite, S-Video, and YPbPr) have their
own audio inputs, two auxiliary audio inputs are also provided (balanced mic
and stereo line-level). Two front panel controls are provided for adjusting the
output volume, one for setting the audio level from the video input and another
one for the AUX input.

The overall audio (sum of the audio from the selected source and the AUX
audio) is embedded in the HDMI and HDBaseT outputs and also is available
on a pair of RCA jacks (stereo).

The unit also boasts a 20 watt internal audio amplifier for direct connection to
4 or 8 Ω speakers (10w per channel into 8 Ω or 20w per channel into 4 Ω).

3.0 Installation

The following diagram illustrates typical input and output connections that can
be utilized with the SC-12BT within a typical system configuration:

Typical installation diagram

For convenience, output connectors on the rear panel have RED background.

3.1 Connecting the Video Inputs

The SC-12BT supports connection to a variety of different input sources,
making it a versatile addition to any AV installation. This unit supports four
HDMI inputs, four VGA inputs(four 3.5mm VGA corresponding audio
inputs), one YPbPr (Component) input, two Composite Video inputs, and one
S-Video input. Please be advised that the USB port on the unit is only
intended for service (firmware update), and does not support any video or data
pass-through.

Video inputs highlighted on the rear panel

3.2 Connecting the Scaled Outputs

The SC-12BT supports three different output types allowing flexible and
reliable connection to a variety of displays and equipment. The output types of
this model include VGA, HDMI, and HDBaseT (Class B or HDBaseT-Lite™).
The video output area on the rear panel also has left and right line level analog
audio outputs.

3.3 HDBaseT UTP (Twisted Pair Catx) Connection

The SC-12BT Scaler Switch provides an HDBaseT output for connection to
any HDBaseT compliant receiver including those built-in some displays and
projecctors.

Hall Research's UH-1BT-R

is the ideal and lowest cost receiver recommended
for use with the scaler. The output on the scaler is Class B or HDBaseT­Lite™, it is compatible with all classes of HDBaseT receivers (Lite or non­Lite), and the maximum extension distance supported through this output is
230ft (70m). We recommend using 23 gague Category 6 UTP cable for the
connection between the scaler’s HDBaseT output and the corresponding
HDBaseT receiver and if the distance is equal to or longer than 200 ft,
shielded category cables are recommended. For best results we recommend
using Alliance approved cables listed at www.hdbaset.org/cables

The HDBaseT output of the switcher only carries the video (and embedded
audio) and no data or power is extended through this port.

3.4 Audio Subsystem and Amplifier Connections

It is important to understand the audio routing and mixing behavior of the
scaler. Please refer to the block diagram below. The front panel has two
separate audio volume/mute controls, one that affects the selected video input
source, and one that affects the Auxiliary audio input. The resultant audio at
the output is the sum (mix) of the two settings.

The audio signals associated with the source video inputs include:

 embedded audio in the HDMI inputs (no separate audio inputs are

provided for the HDMI)

 4 audio inputs for each of the 4 VGA inputs

 2 audio inputs shared among the 4 AV (TV) inputs

Audio Subsystem Functional Block Diagram

The AUX audio has inputs for both microphone and line level, but only one
volume adjustment is present on the front panel, therefore it is recommended
to connect to one or the other AUX audio input (either MIC IN or LINE IN),
not both simultaneously.

 The Microphone input is balanced and features a preamplifier suited for

most dynamic mics. It does not provide phantom power, so avoid using
condenser mics that need external phantom power.

 The Line input is unbalanced and has left and right channels. It is suitable

with most stereo outputs including PCs, music players, receivers, etc.

6.0 Troubleshooting

If you are experiencing problems getting the scaler to work properly, please
use the following troubleshooting suggestions.

o Make sure the power LED is lit on the front panel. If not check power

connection and ensure that all of the connections between sources and
outputs are firmly secured. Loose connections are the number one cause
of issues.

o Select other inputs, and try changing the output resolution.

o Power cycle the system by unplugging the power supply connected to the

scaler, waiting 5 seconds and plugging it back in.

o If a specific source is not working, verify that the source works when

directly connected to the output display.

o The command “S Reset 1” can be sent to the scaler in order to initiate a

factory reset. Please be advised that this command will reset all settings
on the scaler back to factory default (and set IP config to DHCP).

o If you are experiencing issues with the HDBaseT output of the unit, make

sure that the twisted-pair cable meets the system requirements and check
the length. Try using a short cable as a test. Be advised that the HDBaseT
output of this unit is Lite™ (Class B) rated for up to 230ft (70m) at 1080p,
and it does not support IR, RS-232, or PoH (power over HDBaseT)
extension.

If you are still not able to get the system working properly, contact Hall
Research support (preferably via email or the form on support page of
www.hallresearch .com) with a detailed description of the issue and the
troubleshooting steps you have taken.

Do not open or try to repair the unit yourself as this will void your warranty.
To return the extender for repair, you must contact HR Support at 714-641­6607, via email, or on our website. To ship the unit back for repair, make sure
to obtain a Return Material Authorization (RMA) number.
