ACMEE Magic Sound 4S 192K
Magic Sound 4S ES9018K2M 192K/24Bit DSD128 USB DAC HiFi Portable Type-C to 3.5mm/4.4mm Headphone Amplifier
Dark blue color Magic Sound 4S, simple and pure.
The Magic Sound 4S amp inherits the exquisite sandblasting workmanship and dark blue of the MF02S. The appearance design echoes and inherits the MF01 and MF02S. It adopts the same intaglio process of the side gully and the MF02S high-end version. It feels great. In terms of appearance, Magic Sound 4 uses a non-button, single indicator light, and seamless design. The appearance is extremely simple and generous, blue is dark, and hearing is pure.
Fully equipped with power supply, seven stars with the moon
The audio power supply of the Magic Sound 4S amp adopts ±5.5V boost and ±4.8V ultra-low noise LDO design, which effectively reduces power supply noise. The DAC left and right channel power supplies are separated, using two 3.3V LDO power supplies to improve the left and right channel separation . Plus the 3.3V power supply and 1.2V power supply for the digital circuit. Magic Sound 4 has 7 power chips in its petite body.
Audio pure land, channels symmetrical left and right
Magic Sound 4S uses the same independent PCB board design for audio circuits as MF02S, which is called pure land technology within the ACMEE team, which is to create an independent pure land for audio circuits and eliminate the interference of digital signals on audio circuits. In addition, in the audio circuit, a completely symmetrical design for the left and right channels is adopted, and the wiring length, wiring width, wiring path, and component layout are consistent to improve the consistency of the left and right channels.
Balance support, amp assist
Magic Sound 4S uses RT6863 high-sound quality and high-drive amp chip, and has both 3.5mm audio and 4.4mm balanced interfaces, which can satisfy most headphone drivers. Please refer to the specification for details.
