AUDIO CLICK. This menu has no submenu. The second line is the current audio
click setting for the selected audio channel(s). Set Audio Click using the left (a)
or right (') arrow button. Select from the options OFF, CHANNELS 1 & 3 or
CHANNELS 2 & 4 to disable Audio Click or enable the specified click
channels.
Audio Click makes it easy to identify the left and right audio channels and the
stereo pairs of the four AES output channels. The Audio Click feature does not
support embedded audio.
When you enable Audio Click, the audio outputs alternate between two sets of
signals. Table 3–1 lists the audio signals output for each audio channel. The
SPG 422 alternates between driving the set 1 state for 2.75 seconds and set 2
state for 0.25 seconds. In the set 2 state, the click channel is silent to help
identify channels. In addition, to help distinguish each stereo pair, each pair has a
different tone.

When you enable Audio Click, the settings of all audio channels are saved
internally. These settings are restored when you disable Audio Click. When the
Audio Click is enabled, other audio settings, such as level and frequency, cannot
be changed. The audio tones use the audio level last set for each channel. To
change other audio settings, first turn Audio Click off.
Menus similar to these access the various Analog Black signal menus—the
Black button selects which Black output. Blacks 1 and 2 are available on all
instruments. Blacks 3 through 6 are only available on instruments with option 1
installed. These menus cover the type of black signal and timing available from
the corresponding black BNC connector on the rear panel. Pressing EXIT returns
you to the Main menu. Figure 3–6 illustrates Black 1 and 2 menu structure,
while Figure 3–7 illustrates Blacks 3 through 6 menu structure.
