Broadcast; impression (3)
I believe the answer is:
air
I believe this clue is a double definition.
'broadcast' is the first definition.
(to air on TV)
'impression' is the second definition.
(I've seen this before)
(Other definitions for air that I've seen before include "piece of music" , "Atmosphere; appearance" , "Feel" , "Divulge" , "Vent; atmosphere" .)
