Specification Brand : Jauarta BulletPoint1 : [4.7 TIMES AMPLIFICATION] 4.7 times magnification, can change the 47K resistor close to the op amp to change the magnification. BulletPoint2 : [EXCELLENT RESISTORS] Using SMD resistor, and the main circuit adopts ±1% accuracy 5 ring metal film resistor, to ensure a good to noise ratio. BulletPoint3 : [4 CHANNEL] power 4 channel preamplifier design, working voltage is DC 12V‑15V, with strong practicability. BulletPoint4 : [DIRECT COUPLING] Direct coupling type amplification, the whole circuit has no coupling capacitance, and the distortion is reduced to 0.01%. BulletPoint5 : [FOR AUDIO DEVICE] Transformer power is more than 5W, which is widely used in audio equipment such as speakers.
