1.The moving pickup is high output, and the booster is not required. 2.The for head is more accurate and the sound is more Playing rock, popular, and other types of music can make the sound more delicate. 3.The life of the for head is generally 4 times that of ordinary piezoelectric cartridges, better durability. 4.The for head can better control the tone color, make the 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 Stylus's multilevel also wears other styli, while reducing the wear on your records Wonderful accessory for phonograph, vinyl record player. Specifications: Model: needle Species; for head, phonograph for head (pickup) 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 output voltages should be the same. Output When the frequency is 1KHZ, the sound vibration in the L direction or direction is 3.54CM/S or the lateral sound channel vibration speed is 5CM/S. The output should be within the of 4DB relative to the specified value (250MV). Inside (ie 200-300MV) Acupressure, when testing the tracking for head tracking ability and electrical parameters, should be measured within the 40MA needle pressure Needle life: 120H Color: White Material: Plastic+Metal Package Contents: 1 x Turntable Stylus Only the above package content, other products are not included.
