Additional information

The SP-HD-4C 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 distribution amplifier also provides analog L/R and digital SPDIF (TOSLINK) outputs for connection to audio amplifiers, headphones, etc.

The distribution amplifier 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.

This distribution amplifier can drive each buffered output up to 12 meters (40 feet) on quality HDMI cables.
