Centrally coordinates a row (3)
I believe the answer is:
din
'a row' is the definition.
(both can mean a loud disturbance)
'centrally coordinates' is the wordplay.
'centrally' says to take the centre.
The middle of 'coordinates' is 'DIN'.
(Other definitions for din that I've seen before include "Cacophony" , "Loud noise, racket" , "Loud annoying noise" , "Hubbub" , "A lot of unpleasant noise" .)
