FURUTECH deMag LP, DISC and Cable Demagnetizer
Or… What the Heck IS that?
The Furutech deMag completely demagnetizes LPs and optical disc media such as CD, CD-R, DVD, MD, Game CD, Photo CD, SACD, and DVD Audio. Plus it’s an indispensable accessory for keeping interconnect cables, connectors and power cords demagnetized to prevent magnetic signal distortion.
Disc Magnetization Is No Mystery
The silk-screened label on an optical disc contains chemical compounds such as iron, nickel, and cobalt. These materials are all strongly magnetic and easily remagnetized. The reflective information-bearing surface of optical media contains 99% aluminum, but 1% of these same highly magnetic materials! Even aluminum is considered a weak magnetic conductor.
Amazingly, optical discs actually magnetize as they play! A magnetic field is actually induced as they spin. This same elemental process takes place with CD, CD-R, DVD, and MD. Particular attention is due MD as it’s the most prone to magnetization effects such as problems reading discs.
Other so-called demagnetizers on the market including specialist products, head erasers, bulk erasers, etc. don’t even completely demagnetize your discs. Rather, some of them actually induce magnetism! Take spinning demagnetizers, for example. After the disc stops, a section of the CD is left exposed to the fixed magnet below. Because Furutech’s deMag Ring Magnet Technology ramps the power up then down again, all residual magnetism is completely removed.
Demagnetization Isn’t Just For Optical Media Anymore!
The deMag works for disc media as well as cables, connectors, and power cords! (See below.) No part of the playback chain should be disturbed by resolution-sapping magnetic interference.
The graphs below show that untreated magnetic fields have a direct effect on data retrieval. These errors are easily perceived with today’s high resolution systems. Look for coarse video distortion and listen for grainy, unmusical sound.
But magnetism is a naturally occurring process, so it can be said by looking at the data below that it is, in fact, virtually impossible to achieve a clean, precise signal without going through a properly designed demagnetization process!
Furutech’s deMag is the answer. It’s the only way to experience top system performance by demagnetizing optical media, power cords, interconnects of all kinds, and their connectors! You should know that demagnetization was a mainstream technique routinely performed by disc manufacturers all over the world. Because of tight, ultra-competitive pricing, most manufacturers skip this important step these days. Top performance can only be achieved by demagnetizing all discs before recording!
Demagnetizing LPs
How can an LP be magnetized? It’s plastic!
The fact is that pigment added to the plastic during the manufacturing process is the culprit. The minute amount of ferrous material in the pigment causes LPs to become magnetized. Testing at the Tokyo Nanotechnology center with a IHI Gauss meter showed that after an LP was treated with the deMag the magnetic field of the LP was lowered from 620~630 nT to 572~582 nT (nanotesla: a unit of magnetic field strength,1 Tesla = 10,000 gauss).
The Sound
Demagnetizing both sides of optical media before play results in a greater sense of power, dynamics, and resolution, with cleaner, blacker backgrounds and a larger, more stable soundstage, vivid tonal colors and deeper extension at both ends of the frequency range. Demagnetization also allows the delicacy, refinement and nuance of a performance to shine through, along with micro- and macro-dynamics you need to realize the full potential of music and movies.
Using the deMag improves the sense of surround sound involvement in every two-channel and multichannel home theater system. Visceral, exciting sound heightens the participatory sense of music and especially home theater. Details of image and sound that simply weren’t there before enable a truly extraordinary experience.
The Image
Since the deMag Demagnetization Process eliminates all magnetic distortion noise, video displays of all types benefit from less ghosting, color shift, “snow”, vertical and horizontal interference lines. After treatment you’ll notice a higher resolution picture with more finely graded contrast, clean and precise, with bright, beautifully saturated colors and a more sophisticated color pallet.
Don’t forget that the deMag can also be applied to video systems; cables, power cords, audio cables and their connectors!
Demagnetizing Cables
Electric current generates a magnetic field as it flows through a power cord or conductor. However, magnetic impurities within the materials themselves become magnetized and introduce further magnetic distortion. Just loop your cables and power cords with their connectors on the deMag and begin treatment.
No matter how valuable or expensive your system is, the only way to achieve top performance is by demagnetizing your problems away! There are no other demagnetizers on the market that can be used in such a versatile and effective way. The deMag Demagnetizer can even be used on metal-based accessories like CD stabilizers or speaker terminals.
