Questyle M12 Audio Dongle
  • Questyle M12 Audio Dongle

    To greet mobile lossless music in the 5G era, Questyle released the M12 in 2021, a mobile Hi-Fi headphone amplifier with DAC, which integrates Questyle's core technology and carries on the gene of mobile Hi-Fi feature.
    M12 allows all mobile phone users to break through limitations of technology, cost and size of the audio circuit integrated into mobile phones, and feel free to enjoy lossless music from streaming anytime in any place.
    Now, let M12 take you to your mobile Hi-Fi journey!

    M12 supports MQA (Master Quality Authenticated). MQA decoding is a new format of digital coding, which can make audio streams of high sampling rate be packaged into files that are small enough to be suitable for streaming.
    MQA format carries 100% information of the original audio signals. It can fit your audio products in a very smart way and achieve a highest-quality playback of those signals. During this playback, the sound you hear has the same quality as the artists perform in the studio.

    • Tech Specs

      - Operating system required

      • Android phone and pad: Android 5.0 and above
      • PC: Win10 1803 and above
      • Apple cellphone: iOS (You need to buy an OTG cable for Lightning to Type-C.)
      • Apple computer: Mac OS

      - DAC Capability of M12:

      • PCM: 32kHz - 384kHz (16/24/32Bit)
      • DSD: DSD64(1Bit 2.8MHz) , DSD128(1Bit 5.6MHz), DSD256(1Bit 11.2MHz)

      - Output Power:
      Built-in smart detection circuit will automatically self-adjust the output power to fit different
      impedance of headphones.

      • RL=16Ω,Po=46.11mW;
      • RL=32Ω,Po=26.71mW;
      • RL=300Ω,Po=12.26mW;

      When the detected impedance is less than 70Ω, M12 will self-adjust to low gain output.
      When it is more than 70Ω, M12 will self-adjust to high gain output.
      When it is more than 600Ω, M12 will automatically switch to 2Vrms line out.
