Audio click becomes valid when you select 1 Sec to 4 Sec for the audio click rate.
When the audio click is valid, audio tone is turned off for 0.25 seconds around the
click. For example, if you select 3 Sec for the click rate, the audio tone will be
output for 2.75 seconds, and silent for 0.25 seconds; the click occurs during this
silence When Audio Click is set to OFF, the audio tone selected in the Frequency
menu is output continuously. Audio Click makes it easy to identify any channel(s)
of the four output channels.
NOTE. The Audio channel submenu contents are common for AES/EBU audio,
embedded audio, and analog audio except for the menu title on the first line and
some parameter settings.
