Product details

n adopts the brand-new JRC5532.

The main circuit of the n electrolytic capacitor signal adopts, and the main filter capacitor uses 470UF*14 to ensure a strong and continuous power support.

The n resistor selects a five-ring metal resistor, and the main circuit adopts a five-ring metal film resistor with an accuracy of ±1%, ensuring a good signal-to-noise ratio for the entire machine.

The n left and right channel input coupling capacitors adopt ELNA 2.2UF coupling, making the high frequencies clearer and the sound sweeter! The combination of high and low notes is even better!

The n PCB adopts a 1.6mm thick double-sided board with a copper thickness of 2.0 ounces and a full tin-spraying process to ensure excellent performance for both large and small currents. The quality of the PCB.

n adopts a fully enclosed dust-proof potentiometer, which has more stable performance and is more durable than ordinary potentiometers!

The wiring layout of the entire circuit board is quite rigorous and reasonable. The operation is stable and reliable, with a solid and powerful low frequency, an excellent signal-to-noise ratio, and a wide dynamic range. The details are clear and the transient response is excellent. It can handle all kinds of music with ease and performs very well in a home audio environment.

The n preamplifier is equipped with an amplification factor switching switch, which can be switched between 3.5x and 7x. The board is equipped with an operational amplifier socket, allowing you to freely replace and upgrade the operational amplifier according to your own preferences. It is flexible and convenient to use, meeting different listening sensations.
