HIFI 5.1 Tone Board DIY Kits HIFI Amplifier Volume Tone Plate

NE5532 Preamplifier Bord HIFI 5.1 Tone Plate Volume Control Panel Preamp Mixer Board Pre-Amplifier Board
Features:1. Using NE5532.
2. The main circuit of electrolytic capacitor signal adopts famous brand from Taiwan, and the main filter capacitor adopts Japanese Erkon capacity 2×1000UF, and adopts 1A and above rectifier bridge to ensure strong continuous .
3. The resistance uses five-ring metal resistance, and the main circuit adopts a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine.
4. The left and right input coupling capacitor adopts Siemens 1UF coupling from Germany, the treble is clearer and the sound is sweeter! The combination of high and low sounds is more perfect!
5. The adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. First-class quality.
6. The fully enclosed dust-proof potentiometer is more stable and more durable than ordinary potentiometers!
7. Using gold-plated round hole IC socket, you can freely replace op amp ICs according to your preferences
8. The wiring layout of the whole circuit board is quite rigorous and reasonable, and the whole wiring adopts one-point grounding method. The work is stable and reliable, the low frequency is steady and powerful, the signal-to-noise ratio is excellent, and the dynamic range is wide; the details are clear, the transient response is excellent, and all kinds of music can be played freely, and it has a very good performance in the home environment.Description::red
