Gustard DAC - A22 MQA DUAL AK4499 USB DAC

  • A22 使用了旗艦芯片AK4499EQ x 2 DUAL MONO,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。兩個聲道DAC電路完全獨立且獨立接地,互不干擾,以實現最佳性能.
  • 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。
  • 使用CPLD可編程邏輯芯片,自行開發的邏輯功能數字集成電路,內置時鐘管理,第二PLL數字整形,DOP解調,PCM / DSD去爆開關等專有技術,為出色的音質奠定了堅實的基礎;
  • 8通道Discrete轉換電路和獨立的加法器電路,完全滿足AK4499輸出電流的要求,並確保從源頭獲得高音質
  • 數字和模擬電路均使用專門定制的50W音頻專用環形變壓器,該變壓器是完全獨立的並且不會相互干擾;
  • 本機全平衡架構,無需任何轉換,即可完成兩通道全平衡輸出;
  • PRE-AMP 支持高質量的0dB〜-90dB數字音量調節,總共90個位置,並帶有遙控器,可輕鬆調節音量;
  • 使用LCD屏幕和新開發的用戶界面,可為您帶來全新的體驗
  • A22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

Gustard DAC - A22 MQA DUAL AK4499 USB DAC

  • A22 used a Flagship chip AK4499 x 2 DUAL MONO, 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.
  • Using CPLD programmable logic chip, self-developed logic function digital integrated circuit, built-in clock management, 2nd PLL digital shaping, DOP demodulation, PCM/DSD depop switch and other exclusive technologies, laying a solid foundation for excellent sound quality;
     
  • 8-channel hybrid discrete IV conversion circuit and independent adder circuit, fully meet the requirements of AK4499 output current, and ensure high sound quality from the source;
  •  The digital and analog circuits each use a specially customized 50W audio dedicated toroidal transformer, which is completely independent and does not interfere with each other;
  • Native fully balanced architecture, without any conversion, complete two-channel fully balanced output;
  • The analog LPF circuit uses the discrete line independently developed by Gustard, and has carefully adjusted each level of parameters to achieve the best working condition;
  • Supports high-quality digital volume adjustment of 0dB~-90dB total 90 positions, with remote control for easy adjustment of volume;
  • Using 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, 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.
