Krell HDMI 4K HDR Switcher.
The switcher extends the video capabilities of Foundation, Foundation 4K, S-1200 and Evolution 707 to full 4K with HDR, as described in the HDMI v2.0b specification. HDR (High Dynamic Range), as defined by the HDR10 or Dolby Vision specifications, increases the colour gamut from 256 colours to at least 1024 colours, producing an image with stunning clarity, brightness and realism.
When used with Foundation or Foundation 4K, the switcher provides three HDMI inputs for 4K HDR sources, replacing HDMI inputs 2-4. Integration is as simple as connecting the switcher according to the instruction manual and running the software update from the front panel of Foundation or Foundation 4K. No changes to the device configuration (unless HDMI input 1 is in use) or home control system programming (if present) are required.
For the S-1200 or Evolution 707, the addition of the switcher increases the number of HDMI inputs from four to six (three for 4K HDR and three for non-4K sources). Both units will require updated software that can be installed using a home computer and Krell's Software Update Utility program.
