4K UHD Prescaler
4K UHD Prescaler
On the KMX-3901-IN-16Q configured as a 4K UHD prescaler, the input connectors
3G/HD/SD IN 3, 4, 7, 8, 11, 12, 15, and 16 are not used. The connectors listed in the table
below support quad link 3G-SDI signal sources.
Make sure that the 4K UHD prescaler card and its 4K UHD source signals are all referenced
together. The refresh rate of the prescaler card outputs follow the refresh rate of the input
reference signal. The eight audio channels embedded into the output signal come from
video input 1 for head 1 and from video input 5 for head 2.
