The purity in the sound wave goes beyond mere listening
When the fingertips lightly touch the play button, the synergy between the AB5301 decoding chip and the NE5532X3 operational amplifier allows every note to break free from constraints, resulting in precise audio reproduction. With a ±12DB adjustment range for both treble and bass, the low frequencies dive deep like echoes from the ocean, while the high frequencies are as transparent as morning mist brushing against strings.
The low distortion enhancement of TPA3221 enables a shocking sound field on a 3.96-inch column speaker with an output power of 4 ohms 100W×2, while maintaining a -100DB signal-to-noise ratio and -95DBTHD+N delicacy.
The stable connection of Bluetooth 5.3 instantly turns the playlist on your phone into a sound field in the living room. Plugging in a USB drive directly can also evoke those old times hidden in the digital world.
It's not just an amplifier, but also a "translator" between you and music, delivering every emotion directly to your ears.
