    Hardware configuration
    Being equipped with the XMOS platform allows the Q1 Mark II to support decoding up to 384 kHz/32 bit PCM as well as up to DSD256 (the latter is indicated by a green light). When combined with the two separate crystal oscillators, each designed to handle different sampling rates.

    Specifically designed for the iPhone
    By connecting the included Lightning-tomicro USB cable from the iPhone to the Q1 Mark II, you can continue to use your 3.5mm headphone jack headphones for the highest-quality audio. Your iPhone has never sounded so good. 

    Supports connection to Sony Walkman players
    By using a specially designed adapter cable, you can connect from the WM-Port of your Sony Walkman player to the Q1 Mark II, so that the latter may do digital decoding duties.

    Partners well with your computer
    The Q1 Mark II can be used as a USB DAC when paired with a computer through a USB cable, decoding audio formats up to 384kHz/32 bit PCM. With a Mac, the FiiO Q1 is automatically recognized when connected with no need to install a separate driver. With a Windows computer, a special driver from FiiO is required, which will also allow for ASIO output.

    Perfect companion to players and amplifiers
    The Q1 Mark II contains a 3.5mm multifunction connector used for line-input and line-output duties. When this is used as line-input, the Q1 Mark II can be used purely as an amplifier to be paired with another player. When this multifunction connector is used as line-output, the Q1 Mark II can be used as a DAC and be hooked up to an external amplifier.

    Innovative ADC volume adjustment technology
    The Q1 Mark II employs a clever ADC volume adjustment mechanism - by accurately reconstructing the ADC curve, problems such as volume imbalance between the left and right channels and noise when adjusting the volume are all avoided while also greatly enhancing volume adjustment accuracy with each turn of the knob.

    Stylish obconical volume knob
    The volume knob employs a unique obconical design, which allows us to maximize the knob's diameter to make it easier to rotate while still fitting it into a limited space. The 45-degree lines etched on the surface and the red ring that adorns this knob ensures a fashionable touch.

    Form and function come together in a stunning all-metal shell
    The fully metal exterior is not only aesthetically pleasing, but also effectively protects the Q1 Mark II's innards from electromagnetic experience, ensuring sound quality is not compromised when it is used together with an iPhone.

    Switch to your heart's content between single-ended and balanced outputs
    The Q1 Mark II comes with both a single-ended and a balanced headphone output, for two delicious but distinct flavors of audio.

    Automatically determines input type for ultimate ease of use
    The USB interface of the Q1 Mark II automatically determines what type of device it is paired to, so you do not have to manually switch to the optimal settings. For instance, if the Q1 Mark II is paired with an iPhone, it will automatically recognize that and turn off charging over USB. On the other hand, if the Q1 Mark II is paired with a computer, it will also automatically identify that and turn on charging over USB to make sure the Q1 is constantly powered.

    Gain and bass-boost switches
    The Q1 Mark II features a switch for adjusting gain as well as another switch to fine-tune bass levels. Change the amount of gain depending on how sensitive your headphones are, and tailor the bass level to your liking depending on the music you listen to.
