3. Menu Operation DD35 Production Switcher
3 – 216 Operating Instructions – Rev. 16 / 10.2001
The button Assign Buttons opens a second dialog page. This page enables as-
signment of the audio channels to the individual buttons of the external Aux busses
for Audio Program / Audio Preset.
Operating:
The audio switcher follows only PGM (PST). Only PGM is always to be heard. The
crossbar selection only is switched. If there is no audio assigned to the video, the
last audio source stays.
CUT PGM and PST sources swap according to the video
AUTO works only correctly when the associated audio sources
differ from each other. Otherwise, the equal audio
sources are temporarily muted.
PGM/PST enables to control the two busses as EXT AUX
BUSSES. When switching on these and simultaneously
on the corresponding video crossbar, the principle is
applied that “the last” is winning.
With the ESAM2 protocol, transition with the fader is not possible.
