Vinyl Record Player Preamplifier Board / Kits MM MC Phono Amplifier
NE5532 / LME49720NA OP Amp Chip Dual Circuit
Notice:
Do not connect this board to an antique turntable. Most of them have no turntable ground wire and already have a phono amplifier inside. Special turntables without a turntable ground wire and carbon core stylus may not be used.
Product Materials:
1. Novartis 35V6800UF special audio capacitor is used for filtering. The voice is very good, and the effect is better than that of common low-end capacitor filtering array.
2. The resistance is American DALE or VIS resistance, the output capacitance is German ERO, and the decoupling adopts advanced resistance and capacitance such as red WIMA and ELNA.
3. The PCB is a double-sided gilding process, and the line routing is grounded at one point.
Working Voltage: AC 12Vx2 to AC 20Vx2
PCB Size: 110x76mm
Operational amplifier selection:
NE5532: Low frequency thick and warm, classic ;
LME49720NA: Strong analytic hierarchy, better distortion;
Tips:
The MM cartridge has a higher output level, about 1mV to 5mV ;
The MC cartridge has a lower output level, about 0.1mV to 0.5mV ;
