Meant to use mixed media (5)
I believe the answer is:
aimed
'meant' is the definition.
(aiming is a kind of meaning)
'mixed media' is the wordplay.
'mixed' indicates anagramming the letters.
'media' is an anagram of 'AIMED'.
'to use' is the link.
(Other definitions for aimed that I've seen before include "Directed, targeted" , "Media (anag)" , "Directed towards specified goal" , "Focused on as target" , "Drew a bead on" .)
