Tech Specs
4K/UHD Down-Conversion
• Real time, dedicated 4K down-conversion output
(1 x BNC)
• 4K to 2K down-conversion
• UltraHD to HD down-conversion
Downstream Keyer
• Supports graphics with alpha channel over video,
matte or framebuffer, or framebuffer content over
incoming video or matte.
Reference and LTC I/O
• 1x BNC LTC Output
• 1 x BNC assignable to Reference video or LTC input
Reference:
• Analog Color Black (1V) or Composite Sync (2 or 4V)

Physical
• Interface: Thunderbolt 2 (2 x)
• Power: 10-20V, 30-60W*
* Note: Nominal power is 30W. However, multiple
connected Thunderbolt devices may place additional
power demands on Io 4K, which could increase the
power draw to 60W.
