Audio Menus
The
AUDIO
menus are activated by pushing the
AUDIO
button on the UFC front panel. These menus allow the user
to change audio routing and delay in the system, as well as enable or disable the audio synchronizers (sample rate
converters). Each block of 4 outputs can have their input source selected independently, and also have their
synchronizers enabled or disabled. The serial digital input may contain 4/8 channels of embedded audio, and the
serial digital output of the system may also contain 4/8 channels of embedded audio which correspond to audio
outputs 1-4/5-8. Three submenus are available by turning the knob:
INPUT SELECT, SYNCHRONIZER
and
DELAY
.

DELAY
Audio delay is a global adjustment where the default (delay = 0) position delays the audio just enough to match the
video processing delay through the system. Additional delay can be added by the user with the delay setting on this
menu.

F1 – Activates knob to select the amount of audio delay (0 to 170ms).
Note: The zero value on the display corresponds to the amount of video processing delay. Therefore the displayed
range is (–video delay) to (170ms –video delay).
