Demagnetizers for MC pickups and step-up transformers with iron core. MC step-up transformers and MC cartridges containing an iron core are magnetized due to long years of use and various causes. When magnetized, a magnetic bias is applied and the operating point gets off position causing distortion in the music signal that is being played and deterioration of the sound quality. In order to restore the original sound quality of a product, the magnetized magnetism must be removed.

Here's how the demagnetizer works:
The demagnetizer applies a 440 Hz sine wave to the MC cartridge or step-up transformer. Over a period of 20 seconds, this signal is attenuated exponentially. This demagnetizes the coil frame and the ferrous core material; the magnetic field is reduced to zero. Please refer to the manual for further information.

CAUTION: Please note!

• Air-core MC cartridges and optical cartriges do not have magnetic material coiled and therefore there is no effect even if degaussed.
• When degaussing MM and MI type cartridges, the needle tip must always be removed. Do not use it if the needle cannot be removed or else the magnet will be degaussed
• When degaussing the MC step-up transformer, please disconnect the phono and preamplifier from the transformer and degauss the transformer by itself. The speaker can be damaged from the loud noise
• If the RCA plug does not easily fit, do not insert it in by force. The RCA jack of the unit may break
