Topping D90 MQA

Topping D90 MQA

  • ♬ High Quality Chips:(MQA D90 Version)AK4499 is AKM's flagship model. With current output architecture and 4-channel design. The D90MQA parallels the channels of the AK4499 in pairs for better performance. Only USB input mode support MQA decoding.
  • ♬ High-Resolution Music: With the support of AK4499 and XMOS,D90 can support 32bit768kHz and DSD512 resolutions,and the data magnitude and resolution are far beyond CD and SACD.Customized German Thesycon driver(Win7 and higher).
  • ♬ Bluetooth 5.0 Tech: D90MQA is equipped with CSR8675 chip, supports Bluetooth 5.0 well,supports LDAC/AAC/SBC/APTX/APTX LL/APTX HD and other audio encoding.24bit96kHz HD transmission can be achieved under LDAC encoding.(If you don't need Bluetooth input, you can turn it off in the menu.)
  • ♬ Rich Input Interface: AES,USB,OPT,COAX,IIS,Bluetooth input.Among them, USB,IIS support 32bit/768k DSD512 input;AES,OPT,COAX support 24bit/192k input,BT supports 24bit/96k input under LDAC;IIS input can be set in the machine,compatible with most IIS signals on the market using HDMI transmission.
  • ♬ AK4118 Receiver: It is currently the lowest jitter S/PDF receiver with good compatibility.It is used for D90 OPT,COAX, and AES receivers,all supporting up to 24bit/192kHz.

    Topping D90 MQA VERSION Bluetooth 5.0 DAC AK4499 AK4418 Chips CPLD LDAC DSD512 PCM 32Bit/768kHz USB/AES/IIS/OPT/COAX/BT HiFi Hi-Res Audio Desktop Decoder with Remote Control

    Optional Output:Because the D90 has a fully balanced structure,it is compatible with both balanced and single-ended outputs.You can choose any one output,the other is closed,or both.It is especially convenient when used with other devices.

    Switchable Global Voltage:AC 100-120V 50/60Hz uses 115V,AC 220-240V 50/60Hz uses 230V.

    DAC Flter Mode:D90 provides 6 different PCM filter modes to choose from, there is always one for you.

    Bluetooth Decoder Application:Connect your mobile phone,tablet,and laptop's Bluetooth to D90,and D90 will become your BT decoder.If your device supports LDAC transmission,you will get better sound effects.
