each of the selectable video inputs has an audio input selection linked to it. Whenever
the video input selection is changed, the audio input selection for any AFV-enabled
channel automatically changes correspondingly.
• You can override AFV mode by manually selecting a different audio input even
when AFV is enabled. This does not, however, turn AFV mode off; the next time
the video input selection is changed, the audio will again follow it. AFV mode
can only be disabled through the audio menus.
• The AFV link to each of the video inputs is set through the Audio Setup menu
(see Chapter 6, “Menus: Audio Setup”).
The input selection for channels 1 and 2 cannot be selected independently if 96 kHz
AES Output mode (see Chapter 6, “Menus: Audio Setup”) is enabled; they must then
always be set to the same input source.
When Dolby-E (Data) Mode is enabled (see Chapter 6, “Menus: Audio Setup”), the
audio input selection for channel 1 is locked to AES/EBU, and only this channel
supports Dolby-E Data. SDI Embedded Audio cannot be used while in this mode.
Pressing and holding the Audio In button for one second will take you to the Audio
Setup menu (the same as is available through the Main Menu), from which you can
set additional audio configuration options.
When one input channel is being routed to both output channels through the
Channel In->Out or Aud Follows Vid menu options (see Chapter 6, “Menus: Audio
Setup” for details), only that input channel’s LED will be lit to indicate the audio
input source.
On DPS-475 and DPS-575 units without audio capability, the Audio In button is user-
programmable; that is, the user can assign the button to a desired menu function. See
the “User-Programmable Keys” section later in this chapter for instructions on
assigning this button to a menu function.
Freeze Controls
The freeze controls provide instant access to freezing individual frames or fields of
the incoming video source, strobing the incoming video, or performing a 3:2
pulldown on the input source.
Pressing the Frz Mode button takes you to a menu setting for selecting which freeze
mode will be applied to the incoming video. This is the same as the Freeze Mode
menu option under the Video Setup menu.
Pressing the Frz Mode button multiple times will cycle through the different modes,
or the control knob can be used for selection. The available modes are:
• Frame - freezes an entire frame of the incoming video
• Field - freezes a single field of the incoming video
• Strobe - strobes the incoming video
• Film - applies a 3:2 pulldown to the incoming video, effectively giving
a simulated 24fps look to the video output
Pressing the Take button activates the selected freeze mode and applies it to the
incoming video. The light on the Take button will flash while freeze mode is active.
Press Take again to return to the live video feed.
