Industry-Leading Chipset

The SMSL M400 features Flagship DAC chip AK4499, the audio industry’s highest performance paired with ultra-low phase noise crystal oscillators to provide noise-free and high-quality sound rich with details. When using an A-weighted measurement, THD+N is as low as 0.000058%. Besides, it also supports MQA decoding, just as if you were actually in the recording studio.

Multiple Input/Output

SMSL M400 has multiple input options, including USB, Optical, Coaxial, Bluetooth, and IIS input modes. The highest Bluetooth module features various protocols, for instance, UAT, LDAC, aptX-HD, AAC, and SBC. Besides, there are two outputs ports: full-balanced output and RCA unbalanced output.

Latest Bluetooth Connectivity

The SMSL M400 equips with Qualcomm Bluetooth module, which supports LDAC, APTX / HD, SBC, AAC and the industry's highest specification 24bit / 192kHz UAT format. UAT is a high-definition wireless audio Bluetooth transmission standard developed by HiBy. It supports Bluetooth transmission streams of up to 1.2Mbps and sampling frequencies up to 192kHz, which is faster than any previous standard.

Gorgeous Aluminum Alloy and Glass

The M400 features an excellent visual appearance with a whole piece of tempered glass on the top and an integrally formed aluminum alloy shell, which effectively prevents oxidation. The use of non-magnetic raw materials can not only shield the interference of external magnetic fields but also have no magnetic fields. It is worth mentioning that the M400 can further improve the quality of music.

Full-Functional Remote Control

The SMSL M400 characterizes a color LCD display on the front and newly developed user interface that shows active format type, active input type and more details. It also follows with a full-functional remote control that you can control the device with ease.
