Product description:
1. Use original JRC5532.
2. The main circuit of electrolytic capacitor signal adopts famous brand, and the main filter capacitor adopts 470UF*14 to ensure strong and continuous power support.
3. The resistance uses five-ring metal resistors, and the main circuit uses 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 channel input coupling capacitors are coupled with ELNA 2.2UF, the treble is clearer and the sound is sweeter! The combination of high and low sounds is more perfect!
5. The PCB 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 PCB quality.
6. The fully enclosed dust-proof potentiometer has more stable performance and is more durable than ordinary potentiometers!
7. The wiring layout of the entire circuit board is quite rigorous and reasonable. 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. It has a very good performance in the home environment.
8. The front stage has a magnification switch, which can switch between 3.5 times and 7 times. The board has an op amp socket, which can be freely replaced and upgraded according to your own hobbies, which is flexible and convenient to use and meets different listening feelings.
Basic parameters:
Power supply voltage: Dual AC12V-18V.
PCB size: 117*65mm (width without potentiometer handle length)
Potentiometer distance: left to right 24MM*24MM*35MM (24)
