AGC Bias adjustment screen; each subsequent GPI pulse will cycle through the
allowed adjustment values.
When set to Voice-Over, the unit’s audio voice-over mode (see Chapter 6, “Menus:
Audio Setup”) will be activated by a GPI signal. When the GPI signal is first
received, program audio begins fading down, then voice-over mixing begins. Voice-
over mixing continues while the GPI signal is present. Voice-over mixing is stopped
and program audio begins ramping back up upon release of the GPI trigger. This GPI
option is similar to activating and de-activating the Voice-Over option of the Global
Audio Config sub-menu.
GPI input can be contact closure to ground or TTL signal (0 to 5 volts max.).
GPO Function
Selects the functionality of the GPI Output/Audio Delay Pulse connection of the
Multi I/O breakout cable.
Valid Settings: Audio Pulse, Bad Input, Keyer Active,
SDI Input, Voice-Over
Default Setting: Audio Pulse
When set to Audio Pulse, a pulse will be sent on this output at a regular interval
(approximately every two frames).
When set to Bad Input, a signal will be continuously output when no valid video
signal is present on the currently selected video input.
When set to Keyer Active, a signal will be continuously output when the unit’s linear
keyer is active.
When set to SDI Input, a signal will be continuously output when the unit’s input
video selection is set to SDI.
When set to Voice-Over, a signal will be continuously output while the audio voice-
over mixing is active. This signal will NOT be output during the fade-down and
ramp-up of program audio that preceed and follow, respectively, voice-over mixing.
“Active” output is TTL compatible, 5 volts / 20 mA max.
