★ DAC-A22 MQA version, only with USB input, XU216, support MQA. ★ DAC-A22 MQA version, only with USB input, XU216, support MQA. MQA version must have USB input, MQA only supports USB and other interfaces do not support.★ A22 MQA uses 2 AK4499EQ left and right channels as a pure decoder for DA conversion.★It supports a total of 90 high-quality digital volume adjustments from 0dB to -90dB, with a remote control for easy volume adjustment.★ The 8-channel hybrid discrete IV conversion circuit and independent adder circuit fully meet the requirements of AK4499 high current.★ CPLD programmable logic chips, self-constructed digital integrated circuits with logic functions, exclusive technologies such as clock management, 2nd PLL digital shaping, DOP demodulation, PCM/DSD depop switch, etc., have laid a solid foundation for excellent sound quality.
상품설명
Color:Black Description: 1. The USB module adopts XU216, a dedicated USB AUDIO chip from XMOS, and supports PCM768 DSD512. 2. Rich digital filtering There are 6 types of PCM: Short Delay Sharp Roll-off/Short Delay Slow Roll-off/Sharp Roll-off/Slow Roll-off/Super Slow Roll-off/Low Dispersion Short Delay Filter, There are 2 types of DSD: L-BW and H-BW. 3. The analog LPF circuit adopts a self-developed discrete circuit, and the parameters of each stage are carefully adjusted to achieve the best working state. 4. Native fully balanced structure, without any conversion, complete four-way output. 5. The brightness of the screen is adjustable, and it will automatically remember after 10 seconds of no operation, and the last setting will be maintained next time it is turned on. Humanized operation control. Full interface supports DSD hard solution: IIS supports DSD64, DSD128, DSD256, DSD512 hard decoding; SPDIF, AES/EBU support DSD64, DSD128 hard decoding (DOP mode); Optical supports DSD64 (DOP mode); USB supports DSD64, DSD128, DSD256, DSD512 hard decoding; Digital input: IIS and USB support PCM format: 16-32bit/44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384, 768kHz; DSD64, DSD128, DSD256, DSD512; Coaxial supports PCM formats: 16-24bit /44.1, 48, 88.2, 96, 176.4, 192, 384 kHz; DOP64, DOP128 Optical, AES/EBU support PCM format: 16-24bit /44.1, 48, 88.2, 96, 176.4, 192 kHz; DOP64 Product parameters: USB supports DSD64, DSD128, DSD256, DSD512 hard decoding Decoding chip: AK4499*2 USB module: XMOS XU216 Machine size: 330*260*65(MM) Packing size: length 420*width 360*height 175MM; International voltage AC100V-240V (manual adjustment); Frequency response: 20Hz-20kHz +/-0.08dB Line output: RCA output level single-ended 3.0 Vrms @0dBFS, balanced 6.0 Vrms @0dBFS XLR interface definition: American standard (1 ground, 2 heat, 3 cold)
