EDGE SUBCARRIER
REDUCER MODE
During playback of a tape on which a composite signal has been recorded, in the
playback circuit the edge subcarrier reducer (ESR) is automatically switched on
or off according to the VTR operation. When recording a “Non-Standard” signal,
for example, if the color edges are not as good as with a proper signal, the ESR
can be forced on. This item makes this selection.
