SC-12BT
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).
NOTE All 3 outputs show the same image. The product is not a matrix switch.
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).

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.

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
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.
