Note: •
Clean audio switching is assured only for intentional, controlled switches via user control. Clean audio switching cannot
be assured for failover switches.
•
Clean switching requires that both SDI signals (switch from and switch to) be stable and present, and of the same SDI
format and rate.
•
Clean audio switching function is designed for PCM audio. This function does not assure clean decoded audio when
switching from/to Dolby or other non-PCM audio.
•
Path 1 and 2 have separate, independent CQS sub-tabs. Path 1 CQS sub-tab is left-most CQS sub-tab; path 2 is
right-most CQS sub-tab.
