Process
-
A high-output moving coil cartridge uses mechanical force to press the stylus against the grooves of a phonograph record. The coil's magnetic flux then passes into a preamplifier, which converts the information on the record into audio.
High Output
-
Moving coil cartridges create an output between 20 and 30 decibels lower than other forms of phonograph cartridges. High-output moving coil cartridges increase this output to remove the need for a preamplifier or transformer to boost the output.
-
Coil
-
A moving coil cartridge has the coil attached directly to the stylus, unlike magnetic coils, wherein part of the magnetic circuit attaches to the stylus via a stationary coil. The motion of the coil alters the magnetic flux create an audio signal.
