Description
HI-FI Level Preamp Audio Tone Board LM4610 NE5532 Preamp LM4610 Tone Control Board with Loudness Switchable
Product Description
The LM4610 is a HI-FI level preamp, an ideal replacement for the LM1036, it also uses DC voltage to adjust the volume, treble, bass, and balance of the two channels. The IC also adds a 3D sound field expansion adjustment based on the LM1036, and it also has an equal-loudness switch to compensate for the human ear characteristic curve at low volume.
Feature
1, using original LM4610N+NE5532 2. The main circuit of the electrolytic capacitor signal adopts the famous brand, the main filter capacitor adopts the electrolytic capacitor with a capacity of 4×1000UF, and the full-wave bridge rectifier circuit ensures a strong and continuous power support. 3. 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. 4. 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. Top-notch PCB quality. 5, Using a fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers! 6, the coupling capacitor adopts MET 3.3UF/100V 7. Switch S1 is a 3D sound effect switch, and S2 is an equal loudness switch.
