Specifications:
The LM4610 is a HI-FI front-end and an ideal alternative to the LM1036. It also uses DC voltage to adjust the volume of the two channels, treble, bass, and balance. The IC also adds a 3D sound field broadening adjustment on the basis of the LM1036, and it also has an equal loudness switch to compensate for the human ear characteristic curve at low volume.
Commodity details：
Using the original LM4610N+NE5532.
The main circuit of electrolytic capacitor signal is produced in Taiwan. The main filter capacitor adopts special electrolytic capacitor capacity of 4 × 1000UF and full-wave bridge rectifier circuit to ensure strong and continuous power support.
The five-ring metal resistor is selected as the resistance, and the five-ring metal film resistance with an accuracy of ±1% is used in the main circuit to ensure a good signal-to-noise ratio of the whole machine.
PCB adopts 1.6mm thick double-sided plate, 2.0oz copper thickness, the whole process of tin spraying to ensure the good passing performance of large and small current.
The use of fully closed dustproof potentiometer, the performance is more stable, more durable than the ordinary potentiometer!
Coupling capacitor using 3.3UF/100V.
The switch S1 is a 3D sound switch and S2 is an equal loudness switch.
PCB size: 177*52MM.
Power supply voltage: AC12V-0-AC12V or AC15V-0-15V.
The distance between the potentiometers is 35mm.
Potentiometer function: bass, treble, balance, volume.
Packing: 1*YJ0019 LM4610 Tone Board LM4610N NE5532 4 × 1000UF Tonal Board
