Product description:
Update: Modified some part parameters, improved the low frequency modification, and the overall effect has been improved.
Vinyl record player MM MC phono stage:
Using the special amplifier chip for vinyl record players, the effect is superior to the amplifier board of NE5532 and other op amps. The circuit is designed with a frequency compensation circuit, the sound frequency band is more balanced, the input signal filter circuit has a relatively lower noise floor, and it has a rectifier filter voltage regulator circuit. (Note: the chip is polished, the model is free to ask).
Three versions are available:
1: separate amplifying board (no other accessories)
3: Amplifier board + 2 lotus sockets with 300mm shielded wires
3: Amplifier board + power transformer + 2 lotus sockets with 300mm shielded wire
Working voltage: AC: AC dual 10V-17V
Board size: 65mm*45mm
Overall height: about 23mm
Note: The ground wire of the vinyl machine should be connected to the GND terminal of the power input terminal of the amplifier board. Or connect to the GND ground pad next to the phono input, otherwise there may be interference. If conditions permit, you can connect the utility power to the earth, and the effect will be better.
