1. INTRODUCTION
This 1×4+1 4K UHD HDMI Splitter provides an advanced solution for
splitting and distributing a single HDMI input (up to 4K@60Hz w/ HDMI
2.0 & HDCP 2.2) to 4 HDBaseT outputs as well as to a single HDMI
output with analog stereo audio breakout. The UHD source may be
distributed to any of four HDBaseT Receivers via a single Cat.5e/6/7
cable (up to 70m at 1080p or up to 40m at 4K). Despite HDBaseT’s
10.Gbps bandwidth limitation, 4K UHD HDMI video sources, up to and
including 4K@60Hz (4:4:4, 8-bit) as well as 10/12-bit sources with HDR,
are able to be processed and extended by the use of AVLC (Adaptive
Visually Lossless Compression) when connected to compatible AVLC
Receivers. If the connected HDBaseT Receiver can’t support AVLC,
4K@60Hz RGB/YUV 4:4:4 signals will be converted to YUV 4:2:0 or
downscaled to 1080p based on the detected EDID on each output.
This unit provides solid audio support, including bypassing 8 channel
LPCM digital audio as well as advanced Bitstream and HD Bitstream
audio formats via HDBaseT and HDMI. Additionally, an analog stereo
audio breakout output is available to provide audio to local powered
speakers (LPCM 2.0 sources only).
Standard EDID management functionality is included and the PoH
(Power over HDBaseT) feature can provide power to compatible
receivers, providing greater exibility in installations. Control is via front
panel controls with an OSD and RS-232.
2. APPLICATIONS

4. SYSTEM REQUIREMENTS
• HDMI source equipment such as a media player, video game
console or set-top box.
• Compatible HDBaseT receivers with AVLC and PoH support is
recommended.
• HDMI receiving equipment such as an HDTV, monitor or audio
amplier.
• The use of Premium High Speed HDMI cables, and industry standard
Cat.6, Cat.6a or Cat.7, is highly recommended.
5. FEATURES
• HDMI 2.0 and HDBaseT 1.0 compatible
• HDCP 1.x and HDCP 2.2 compliant
• 1×HDMI input
• 4×HDBaseT and 1×HDMI outputs
• Supports up to 4K UHD (18Gbps, 4K@50/60Hz 4:4:4, 8-bit) video input
and output
Note: Support of resolutions requiring bandwidth above 10.2Gbps
via HDBaseT requires a compatible AVLC receiver.
• Supports Deep Color input and output up to 12-bit
• Supports 10-bit and 12-bit HDR (High Dynamic Range) input/output
• HDBaseT output transmits video, audio and data over a single
Cat.5e/6/7 cable and can reach distances up to 40m/131ft at 4K
when using Cat.6a/7
• HDBaseT feature support: HD Video and Audio, PoH (PSE) and
Control (bi-directional RS-232 and IR pass-through)
• Integrated AVLC (Adaptive Visually Lossless Compression) activates
when the bandwidth requirements of the source are beyond
10.2Gbps allowing for support of sources up to 18Gbps with no loss
of visual quality
• Supports automatic 4K@60Hz RGB/YUV 4:4:4 to YUV 4:2:0 conversion
or downscaling to 1080p for compatibility with non-AVLC HDBaseT
receivers based on the detected EDID on each output
• Supports pass-through of all standard digital audio formats: 8

3
channel LPCM, Bitstream, and HD Bitstream
• High-quality DAC (Digital to Analog audio Conversion) with local
analog stereo audio breakout (LPCM 2.0 sources only)
• Comprehensive EDID management options
• Supports standard PoH from the unit to connected HDBaseT
receivers (compatible receivers only)
Note: The PoH function is designed for powering compatible
Receiver units only. Non-PoH Receivers will need their own power
supply. Receivers from other brands may not be compatible.
• 1U rack mounted design
• Control via front panel controls with an OSD and RS-232
