This supports PCM playback up to 32-bit/768kHz and DSD256
M300 SE is capable of directly sampling PCM digital audio up to 32-bit/768kHz without downsampling. It also supports Native DSD playback up to DSD256 without conversion.
Performance-grade headphone amplifier
The front panel features a 6.35mm single-ended headphone jack and a 4.4mm balanced headphone jack, with an integrated high- performance stereo headphone amplifier that can provide substantial driving power to each interface simultaneously. The chip's proprietary headphone impedance detection allows for automatic adaptation to various types of headphones.
5 PCM Filters
A filter is a step in converting PCM digital audio to an analog signal. It mainly acts on high-frequency signals after about 20khz. The 5 modes of M300SE are shown in the figure below.
Support A MQA full decoding
M300 SE is a complete MQA decoder, which will fully expand MQA music files to provide high-quality sound sources. At this playback level, you will fully hear the content created by the artist in the studio.
Preamp volume control function
M300 SE can turn off the volume control function in the pre- amp mode, keeping the output level at 4.0Vrms (XLR balanced) or 2.0Vrms (RCA single). At this time, the M300 SE works as a pure DAC.
True balanced XLR output
The M300 SE utilises two audio decoding chips, namely the CS43131, combined with the engineer's carefully crafted circuitry, enables more accurate expression of music. Moreover, it employs a substantial quantity of audiophile-grade resistors and capacitors specifically designed for audio purposes, as well as multiple sets of low-noise LDO power supplies.
Wireless transmission Bluetooth 5.0
We have adopted a modular Bluetooth solution with an external Bluetooth antenna, which has significantly improved signal stability and transmission quality in all directions. This advancement has pushed HiFi towards wireless connectivity.
Infrared remote control for easy operation
You can place the M300 SE wherever you like and control all of its functions via remote control. The menu allows for adjustable screen time output settings, ranging from 5 to 30 seconds, which completely turns off the screen and reduces interference.
CS43131*2 | Cirrus Logic Audio D/A Converters
This chip integrates a new generation of low-power audio decoder and high-fidelity headphone amplifier with impedance detection function. It provides excellent professional-grade audio performance, greatly reduces the space occupied on the circuit board to prevent interference between circuits. It supports various Hi-Fi headphones and offers outstanding audio quality.
