Introduction:

MF712 refers to the circuit design of Musical Fidelity. It is a high-quality product of Musical Fidelity that can be switched freely between MM and MC cartridge amplifiers. With excellent technical performance, high exquisite details and beautiful perfect circuit layout, it can be said to be the epitome of master's low-key high-level elegance.

The power supply is integrated and HIFI components are used to match, which has won more favorable comments from Audiophele. With output protection function, protect your expensive audio equipment.

It can also switch between input voltage 110V and 220V at will. You can see that there is a voltage switch position on the PCB, which is very convenient to use in countries with different input voltages. (But you need to pay attention to it. Please set it according to your national voltage. Generally, it is recommended that the 100-120V national voltage is set to the 110V position, and the 220-240V national voltage is set to the 220V position)

 

Product parameters:

● Input voltage: 110V or 220V (AC 18VX2 is recommended for transformer output voltage, You need to install a 110/220 voltage switch on PCB).

● Input impedance: 47K Ω (MM), 100 Ω (MC)

● Input sensitivity: 3mV (MM), 300 μ V (MC)

● Total filtering distortion: 0.01%

● SNR:>80dB (MM) , >70dB (MC)

● Overload margin: 15dB (MM), 22dB (MC)

● RIAA response:+/-0.25dB

● Linear input: RCA

● PCB Szie: 160mm*180mm

 

Note: This is a Bare PCB. You need to match all parts yourself.
