LM4610 With 3D Surround Equal Loudness Volume Adjustment Control Board HiFi Home Audio Preamplifier PCB

Product Details:

Note: There is no circuit diagram and technical support for this project, If you buy 【PCB】, please make sure you have enough electronic foundation to complete it.

【Finished No LM4610】: It has been assembled and tested OK, but there is no LM4610 chip, LM4610 you need to prepare it yourself.

【 PCB】: Does not include any components.

The main circuit of electrolytic capacitor signal adopts Taiwan famous brand, the main filter capacitor adopts electrolytic capacitor with a capacity of 4×1000UF, and a full-wave bridge rectifier circuit to ensure strong and continuous power support.

The five-ring metal resistor is used for the resistor, and the five-ring metal film resistor with an accuracy of ±1% is used for the main circuit, which ensures a good signal-to-noise ratio of the whole machine.

The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents.

Using a fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers!

The coupling capacitor adopts MET 3.3UF/100V

Switch S1 is a 3D sound effect switch, and S2 is an equal loudness switch.
