Introduction - GTB-UHD600-18S-RT
The Gefen GTB-UHD600-18S-RT routes one full bandwidth 4K Ultra HD 600 MHz source to
eight 4K Ultra HD 600 MHz or Full HD 1080p displays. Independent scalers built into each
output will automatically downscale the signal when connected to a 1080p TV.
This HDCP-compliant product has been specically designed to support over 10 layers
of splitting/cascading for awless performance in large video distribution and signage
applications, supporting hundreds of displays.
Cutting edge Smart CEC Management system built into the GTB-UHD600-18S-RT
communicates with the source, other compatible splitters and the displays. It guarantees
that a picture is always present on all displays by ensuring that connected displays are on
and switched to the correct input.
A built-in Pattern Generator helps in troubleshooting during installation or for routine
maintenance. Resolutions up to 4K DCI (4096 x 2160 at 60 Hz), 4K Ultra HD (3860 x 2160 at
60 Hz, 4:4:4 color space),1080p Full HD, and 1920x1200 WUXGA are supported. HDR and
multi-channel digital audio including 7.1 channels of LPCM and HBR (High Bit Rate) lossless
formats are also passed through. The Gefen 1:8 Splitter is the perfect choice for any small or
large 4K video distribution system.

Splitter Connection Instructions
Video
1. Using an HDMI cable, connect an Ultra HD source to the Input port of the splitter.
2. Connect HDMI cables (not included), to Out 1 - Out 8 ports. The HDMI cables can then be
connected in any of the following ways:
hConnect the HDMI cables to Ultra HD displays.
Power
1. Connect the included 5V DC locking power supply to the 5V DC power receptacle on the rear
panel of the splitter.
2. Connect the power supply to an available electrical outlet.
Important
Cable quality is critical when handling 600 MHz HDMI signals. We
highly recommend Gefen Locking HDMI cables. They have been
designed and tested to work at 600 MHz and reliably transport the
full 18 Gbps throughput of HDMI 2.0.

There are two Bi-color LEDs available to indicate the current input selected and
operation mode.
Auto Switching Mode (Default): A Blue Input LED Status indicates the current input
selected and that the splitter is in Auto Switching Mode.
Auto Switching Mode is used for source redundancy. HDMI Input 1 is always priority. If
Input 1 goes down, the splitter automatically switches to Input 2.
Manual Switching Mode: Toggling the Input switch will trigger Manual override.
A Green Input LED Status indicates the current input selected and that the splitter is in
Manual Switch Mode. Refer to the LED Status table for more details (next page).
