neered and each cartridge in the series is indexed with
a DCF number,

The Dynamic Coupling Factor is an index of max-
imum stylus performance when the cartridge is related
to a particular type of playback equipment. This resultant
number is derived from a Dimensional Analysis of all the
parameters involvedt To select a pickup for a profes-
sional manual turntable, with its sophisticated, dynam-
ically balanced tone arm, tracking at an ultra-light force,
a higher DCF index would be required than, say, for a
pickup to be used in an ordinary record changer. For
