Input AFL — Select this to turn the Extron Accu-Rate Frame Lock (AFL) on or off.

When enabled, this mode locks the output vertical refresh rate to the vertical refresh rate of the currently selected input using Accu-Rate Frame Lock technology. This ensures no frames of the input are repeated or dropped due to frame rate conversion. Input AFL mode will cause glitches and/or interruptions in the output sync when a new input is selected, or when a new signal has been routed to the selected input, as the DSC 301 HD locks to the new vertical refresh rate.

If no input signal is detected (AFL disabled), or if locking to the input signal is not possible, a free running pixel clock is generated by the DSC 301 HD.
