Record player (6)
I believe the answer is:
stereo
'record player' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for stereo that I've seen before include "System that gives a three-dimensional sound" , "Sound coming from different directions" , "A 19 player" , "Matched, rivalled" , "When sound comes through two channels" .)
