Description

Alfatron ALF-SUK8-8K 8K HDMI 2x8 Distribution Amplifier

The ALF-SUK8-8K is an HDMI 2.1 switcher and splitter, scaler, and stabilizer with two HDMI inputs and eight HDMI outputs. It supports full HDMI 2.1, FRL 48 Gbps bandwidth, HDR, and HDCP 2.3 compliance to provide stable signal distribution at high bandwidths. The splitter includes audio de-embedding, video scaling, EDID management, and front-panel LED indicators for power and signal status.

Supports video resolutions up to 8K @ 60 Hz 4:2:0, 8K @ 30 Hz 4:4:4, and 4K @ 120 Hz. Its built-in 2×1 switcher allows selection between two HDMI sources, while EDID management supports display EDID or internally stored EDID settings. Independent output scaling supports downscaling from 8K to 4K and from 4K to 1080p for compatibility with legacy displays.

Audio de-embedding provides balanced analog, optical, and RCA audio outputs. The ALF-SUK8-8K supports RS-232, IR, GUI, and TCP/IP control, including network-based firmware upgrades and discovery through third-party management systems. A backlit button provides CEC display on/off control.

Most Alfatron products come with a 7-year limited warranty. Register your product with Alfatron to receive an additional 3-year extended warranty on eligible products, for 10 years of total coverage.

For example: it will output HDCP 1.4 when the source is HDCP 2.3, or 2.2 when connected to an HDCP 1.4 display. It will turn off HDCP if the display does not support HDCP
Can turn off HDCP by DIP switch compulsory
Downscaling Capability Each output can downscale independently
1: “By-PASS” status: it will pass through whatever from inputs to outputs without any processing
2: “AUTO” status: each output will downscale, rules as below:
2.1: If the source is 8K, but the connected displayer max supports 4K, it will downscale to 4K
2.2: If the source is 8K, but the connected displayer max supports 1080p, it will downscale to 4K
2.3: If the source is 4K, but the connected displayer max supports 1080p, it will downscale to 1080p
3: Scale limitation
3.1: Can’t downscale from 8K to 1080p. If the source is 8K, but the displayer's max support is 1080p, it will have a black screen; But, if the source is 4K and the displayer's max support is 1080p, it will output 1080p
3.2: Can’t support 720p or lower resolutions
