Studied broadcast and initiated macho (3-7)
I believe the answer is:
red-blooded
'macho' is the definition.
(I've seen this before)
'studied broadcast and initiated' is the wordplay.
'studied' becomes 'read' (I've seen this before).
'broadcast' indicates a 'sounds like' (homophone) clue (how the word might sound on the radio or TV).
'and' says to put letters next to each other.
'initiated' becomes 'blooded' (to blood is to initiate an animal into violence).
'read' is a homophone of 'red'.
'red'+'blooded'='RED-BLOODED'
(Other definitions for red-blooded that I've seen before include "Lusty" , "Vigorous, virile" .)
