That is to say, 600 ohms input 1V signal voltage, the output voltage of 50K winding is 9.128V, the signal is improved and amplified by nearly 10 times. The transformer wire wraps the iron core through the AC audio signal. You can also order a DC signal transformer, just take a photo and leave a message.\u003c\/p\u003e\u003cp\u003eThe transformer inputs 4 wires and outputs 4 wires. The primary and secondary layered winding of the transformer is to balance the input and output in two groups, instead of the conventional two-wire parallel winding method, it adopts a more special process, with the same number of turns, the same wire diameter, the same copper resistance, and the same internal resistance. The voltage is the same, the current is the same, the positive and negative voltage amplitudes are the same, a completely balanced signal transformer! It can be used as a passive front stage, single-ended to single-ended, single-ended to balanced, balanced to balanced, and balanced to single-ended.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThis transformer is specially designed and manufactured for signal coupling and passive pre-stage use.
