 S.M.S.L. M400 MQA AK4499 USB DAC 

  • M400使用了旗艦芯片AK4499,該芯片是32位4通道開關電阻DAC,採用最新開發的技術實現了業界領先的低失真和低噪聲特性(輸出噪聲低至1.5uVrms)。最高的音質和最佳規格,已達到最新高度。
  • 支持MQA FULL解碼。不同的設備和不同的播放方法將播放同一MQA文件的不同聲音效果。MQA的工作方式是將摺紙之類的模擬音頻“折疊”成一個較小的文件。一旦在解碼器上播放此文件可以讀取MQA文件的文件,可以重新打開折疊的部分以釋放最高分辨率的音樂。誠然,播放質量取決於您的設備,但至少此文件具有復制原始錄音的潛力。
  • 最新的藍牙5.0支持APTX HD,SBC,AAC和業界最高規格的24bit / 192kHz UAT格式!在享受無線技術的同時仍能感受到技術的力量。
  • 使用彩色LCD屏幕和新開發的用戶界面,可為您帶來全新的體驗,全功能的遙控器。無論您坐在哪裡(在設備附近),都可以隨意控制它。 
  • M400將具有USB,光纖,同軸,藍牙和IIS輸入。對於輸出,它將具有RCA和XLR功能。支持LVDS電平差分I²S接收(使用HDMI接口),可以接受最低的抖動數字音頻!到8種輸入模式,與大多數音頻源兼容!此DAC僅通過USB體驗MQA。

S.M.S.L. M400 MQA AK4499 USB DAC  

  • M400 used a Flagship chip AK4499, This chip is a 32bits 4-channel switch resistance DAC, which uses newly developed technology to achieve industry-leading low distortion and low noise characteristics (output noise as low as 1.5uVrms). It was the audio industry's highest sound quality and best specification. Has reached the latest height.
  • Support MQA FULL decoding. Different equipment and different playback methods will play different sound effects of the same MQA file. The way MQA works is to "fold" the analog audio like origami, become a smaller file. Once this file is played on a decoder that can read MQA files, can reopen the folded part to release the highest resolution music. Admittedly, The playback quality will depend on your device, but at least this file has the potential to reproduce the original recording.
  • The latest Bluetooth 5.0 supports APTX HD, SBC, AAC and the industry's highest specification 24bit / 192kHz UAT format! Enjoy the wireless while still feeling the power of technology.
  • Using color LCD screen and newly developed user interface, give you a new experience, full-function remote control. No matter where you sit (near the device), can control it at will.
  • M400 will have USB, Optical, Coaxial, Bluetooth, and IIS inputs. For outputs, it'll have RCA and XLR capability. Support LVDS level differential I²S reception (using HDMI interface), it can accept the lowest jitter digital audio! Support up to 8 input modes, compatible with most audio sources! This dac decide mqa through only usb.
