Introduction
OVERVIEW
Thank you for purchasing the SP-HD-4C, a 4-channel HDMI Splitter from Hall Technologies.
This Splitter can distribute an HDMI audio/video source to up to 4 displays simultaneously without any
loss. It is compliant to HDCP 2.2 and supports 4K UHD resolutions up to 4K @ 60Hz (4:4:4), HDR and
3D. This splitter can drive each buffered output up to 12 meters (40 feet) on quality HDMI cables.
The splitter is capable of scaling 4K signal down to 1080p independently for each output. This allows
users to accept a 4K video source and distribute it to a mix of 4K and 1080p TVs without downgrading
the image for all outputs. Users can simply set the max resolution at each output to be 4K or 1080p.
The device is HDCP compliant, digitally splits, and buffers the input signal for a 100% perfect image and
sound reproduction on all outputs. The splitter also provides analog L/R and digital SPDIF (TOSLINK)
outputs for connection to audio amplifiers, headphones, etc.
FEATURES
• Lossless Ultra HD 4K distribution to 4 UHD or HD outputs
• Supports 4K UHD @ 60 Hz 4:4:4, HDCP 2.2 and HDR
• Supports 30/36/48-bit color depth.
• Full 3D video support including frame packing up to a 297 MHz TMDS clock.
• Provides De-embedded analog and digital audio outputs.
• Can Scale 4K to 1080p independently at each output (can mix 4K and 1080p TVs)
• Smart EDID Management
• LED status indicators for source signal, and 4 output connections
• High bit-rate digital audio - DTS-HD, Dolby True HD, DTS, Dolby- AC3, LPCM 7.1 and DSD
• Can be cascaded up to 3 levels.
• Each of the buffered outputs can run up to 12 meters (40 feet) using quality HDMI cables.
• Locking DC input power supply connector

MAC OUTPUT RES
• Controls HDMI output down sampling to 1080p
- When set to 4K (default), the output resolution is the same as input resolution.
- When set to 1080p, the output resolution is the same as input up to 1080p, but
if the input resolution exceeds 1080p, it gets scaled down per the following:
3840x2160 is down sampled to 1920x1080p.
4096x2160 is down sampled to 2048x1080p.
• This allows the users to use a 4K videos source and show It as 4K with no reduction in
quality on 4K displays but they can also use legacy 1080p TVs and a display on them
with 1080p resolution.

Installation
Connection Block Diagram
Preform the following steps to install the SP-HD-4C.
1. Make sure your HDMI Sources and Displays that you are intending to connect are powered off
and disconnected from power sources.
2. Using Hi-speed HDMI cables, connect each display to the Outputs ports of the splitter.
3. Similarly connect the video source to the Input port of the splitter.
4. Power the splitter using the supplied DC power supply.
5. Power on all the displays followed by source.
6. Make sure the LED indicators for the HDMI Input and corresponding HDMI Outputs are
illuminated.
7. Verify audio and video at each output display.

Smart EDID Management
When the unit powers up or when it first detects that a video source is connected the device, it creates
an EDID for the source based on the first display found scanned from #1 to #4, in order.
If you have a mix of 4K and 1080p displays, make sure to connect the 4K display to output #1. That way
the EDID generated for the source will have 4K native causing the source to output a 4K image. Then
for the displays that do not support 4K, set the max resolution Dip Switch on the front panel to 1080p
(see next section).
If no displays are connected, the splitter uses an internal "default" Hall Research EDID so the HDMI
source will always send a signal. This internal EDID will be used until an external display is connected to
one of the output ports.
Once an external EDID is found, it is retained until power is cycled, even if the output display is
exchanged for another.
The SP-HD-4C maintains the audio extraction feature even if there are no active displays connected to
the outputs.
*Note: Only use the regulated 12 vDC supply (center positive) supplied with the unit. Never substitute
any other power supply as this can destroy the unit.

Per Output Downscaling from 4K to 1080p
If you have a mix of 4K and 1080p TVs, you can still use the splitter and maintain 4K resolution from the
source to all the 4K TVs while downscale the 4K to 1080p so it can be displayed on the 1080p TVs.
The front panel has a 4 position Dip Switch for downscaling 4K video. Each switch position corresponds
to each output. Make sure to connect your 4K TV to output #1 (so the EDID for video source uses 4K
native), then for each of the TVs that do not support 4K, set the Dip Switch to 1080p max.
