Description:

Basic parameters:
   Supply voltage: AC 12V-18V.
   PCB size: 140*70mm (width does not include potentiometer handle length)
   Potentiometer distance: left to right 24MM*24MM*24MM

feature:
1. Use the original JRC5532.

2. The main circuit of electrolytic capacitor signal adopts famous brand, and the main filter capacitor adopts ELNA capacity of 6×1800UF 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 WIMA 1UF 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 board is quite rigorous and reasonable. 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. The front stage has a zoom switch that can be switched between 5 and 9 times. The board is equipped with an op amp socket, which can be freely replaced and upgraded according to your own hobby. It is flexible and convenient to meet different listening sensations.

  Packing: 1 JRC5532 tone finished board
