1. The moving magnetic pickup is high output, and the booster is not required.2. The magnetic head is more and the sound is more pure. Playing rock, popular, jazz and other types of music can make the sound more delicate.3. The life of the magnetic head is generally 4 of ordinary piezoelectric cartridges, better durability.4. The magnetic head can better control the tone color, make the medium frequency warm and wide, the low frequency is full and flexible, and the high frequency is and dry.5. Paratoroidal coils generating efficiencyStylus's multilevel shape also wears other styli, while reducing the wear on your recordsWonderful accessory for phonograph, vinyl record player.Specifications:: needleSpecies; Magnetic head, phonograph head (pickup)Drive mode; electromagneticTrack number; Dual channel (stereo)Polarity: When the tip is laterally (left and right), the phase of the left channel (L) and right channel (R) output voltages should be the . Output voltage: When the frequency is 1KHZ, the sound wave vibration velocity V in the L direction or R direction is 3.54CM/S or the lateral sound channel vibration speed is 5CM/S. The output voltage should be within the range of +/- 4DB relative to the specified value (250MV). Inside (ie 200-300MV)Acupressure, when testing the tracking head tracking ability and electrical parameters, should be measured within the 40 +/- MA needle pressure rangeNeedle life: 120HColour: Material: ABSSize: 35mmPackage Contents:1 x gramophone cartridgeOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing.
