1. The moving magnet pickup has high output, and no amplifier is needed. 2. The magnetic needle is more sensitive and the sound is purer. Playing rock, pop, jazz and other types of music can make the sound more delicate. 3. The lifespan of the magnetic needle is generally 4 times longer than that of ordinary piezoelectric cartridges, providing better durability. 4. The magnetic needle can better control the timbre, making the midrange warm and wide, the bass full and flexible, and the treble clear and dry. 5. Paratoroidal coils generate efficiency. The multi-stage shape of the pins also wears less than other pins, while reducing wear on your records. Great accessory for gramophone, turntable. Specifications: needle type; Magnetic needle, gramophone head (pickup) Drive method; electromagnetic Tracking number; Dual channel (stereo) Polarity: When the tip is sideways (left and right), the phase of the left channel (L) and right channel (R) output voltages must be in phase. Output voltage: When the frequency is 1KHZ, the vibration speed V of the sound wave in the L direction or R direction must be 3.54CM/S or the vibration speed of the lateral sound channel must be 5CM/S. The output voltage must be within the range of +/- 4DB relative to the specified value (250MV). Within (i.e. 200-300MV) Acupressure, when testing the tracking ability and electrical parameters of the track head, must be measured within the range of 40 +/- MA needle pressure. Needle life: 120H Color: Material: ABS Size: 35mm Package contents: 1 x gramophone cartridge Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture to differ slightly from the real thing. The allowed measurement error is +/- 1-3cm.
