ACMEEAUDIO 4S USB DAC Headphone Amplifier 192K/24BIT DSD128 Game Cellphone Audio Decoder Silver

Description:
The DAC headphone amplifier is small, powerful, and easy to use. It can significantly improve the sound quality of mobile phones, computers, and tablets, and effectively filter background noise to improve the sense of hearing. We have been dedicated to bringing good equipment to more enthusiasts.

It adopts RT6863 high-fidelity high-driving headphone amp chip, symmetrical balanced circuit, independent audio PCB, low-noise LDO and ±5.5V audio power supply. And it also has a 3.5mm audio terminal and a 4.4mm balanced interface, which can meet the drive of most headphones and bring you a good experience.

The headphone amp adopts ±5.5V audio power supply. The power supply of the left and right channels of the DAC is separated, and five LDO power supplies are used respectively, which improves the separation of the left and right channels, with digital circuit 3.3V power supply and 1.2V power supply. It has 6 power chips installed inside just for better sound.

Clean audio. It uses the same audio circuit independent PCB board as MF02S, which eliminates the interference of digital signals to the audio circuit and creates an independent pure land for the audio circuit. In addition, in the audio circuit, it adopts a completely symmetrical design of the left and right channels, and the trace length, trace width, trace path, and component layout are consistent to improve the consistency of the left and right channels.
