Product details of HIFi 2.1 Stereo+Subwoofer Pre-Amplifier Bass Tone Control LFE Filter
- Product Description:1. Use the NE55322. The main circuit of electrolytic capacitor signal adopts Taiwan famous brand. The main filter capacitor adopts Japan’s Panasonic capacity of 2×3900UF, and adopts 2A and above rectifier bridge to ensure strong and continuous power support.3. The resistor uses a five-ring metal resistor. The main circuit uses a five-ring metal film resistor with an accuracy of ±1% to ensure a good signal-to-noise ratio.4. The left and right channel input coupling capacitors are coupled with Siemens 0.47UF imported from Germany. The treble is clearer and the sound is sweeter! High and low sounds are perfect!5. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. First-class PCB quality.6. With fully enclosed dustproof potentiometer, the performance is more stable and more durable than ordinary potentiometers! 7. The layout of the entire circuit board is quite rigorous and reasonable. The overall PCB trace is grounded at one point. The work is stable and reliable, the low frequency is solid and solid, the signal-to-noise ratio is quite excellent, the dynamic range is wide, the details are clear, the transient response is excellent, and all kinds of music are played comfortably. It has a very good performance in the family’s playback environment.8. LOW PASS crossover point, upper limit frequency adjustment range: 50-150Hz 9.PCB size: 180*55MM10. Power supply voltage: AC12V-0-AC12V or AC15V-0-15VPotentiometer function: low frequency adjustment, subwoofer volume. Left and right channel volume, bass, treble.11. Same as picture.12. We check before packaging.13. Chat for any query.
