Features: 1.The moving magnetic pickup is high output, and the booster is not required. 2.The magnetic head is more accurate 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 times that 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 bright and dry. 5.Paratoroidal coils improve generating efficiency 6.Styluss multilevel shape also wears better than other styli, while reducing the wear on your records 7.Wonderful accessory for phonograph, vinyl record player. Specifications: Model: needle Species; Magnetic head, phonograph head (pickup) Drive mode; electromagnetic Track number; Dual channel (stereo) Polarity: When the tip is driven laterally (left and right), the phase of the left channel (L) and right channel (R) output voltages should be the same. 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 40MA needle pressure range Needle life: 120H Packing List: 1 x Phonograph Stylus Note: 1.Transition: 1cm=10mm=0.39inch 2.Please allow 0-3cm error due to manual measurement. pls make sure you do not mind before you bid. 3.Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
