    Connecting from TV with a single HDMI cable
    The only connection between the AI-303 and a TV is an HDMI cable. Supporting ARC/eARC and HDMI CEC, volume control and power on/off of the AI-303 can be controlled from a TV remote, while receiving PCM 192/24 Hi-Res audio as long as the TV supports the resolution. Thanks to its small footprint, installing the AI-303 on a TV cabinet is possible.
    * Please set the digital output to "PCM" in the output settings of the TV.

    Supporting DSD512 and PCM 384/32 Hi-Res audio formats
    In order to maximize studio master quality sound quality of the digital source, the D/A converter on the AI-303 equips two types of digital filters and x2Fs, x4Fs, and x8Fs up-conversion processing to pursue your preferred sound.


    Wide range of digital inputs, HDMI, USB-C, Coaxial, and Optical
    Connections with the digital sources are up-to-dated. The AI-303 equips an HDMI for TV, a USB-C for PC/Laptop and Coaxial/Optical for conventional digital music players, maximizing potential of each digital source with the high performance D/A converter.

    Built-in Bluetooth® receiver supporting LDAC®, and Qualcomm® aptX™ HD
    The Bluetooth® receiver is employed for easy wireless connection with a smartphone, supporting high-resolution wireless codecs including LDAC®, LHDC, and Qualcomm® aptX™ HD, in addition to other standard Bluetooth® codecs such as Qualcomm® aptX™, AAC, and SBC. The LEDs on the front panel indicate which codec is engaged when connection is established.

    USB-C for versatile USB connection with PC, Smartphone and Tablet

    The AI-303 also supports wide variety of digital devices such as smartphone/tablet and portable digital audio player that support USB Audio 2.0, via a self-powered USB-C port allowing auto device detect when the device equips a USB-C. Most Android devices and recent iPad Air/iPad Pro that equip USB-C port allow single USB-C cable connection without extra devices.
    *1 An additional USB Camera Adapter from Apple is required when connecting to an iPhone.
    *2 When connecting to an Android device, "OTG Connection" must be turned on or "USB Debug" must be turned on from the developer option menu.


    MQA full decoding
    The AI-303 supports MQA full decoding to enjoy studio master quality sound, from any digital inputs USB-C, HDMI, Coaxial and Optical inputs from MQA streaming and MQA CD from CD player via digital connection.

    “Bulk Pet” digital audio transmission
    When sending a huge amount of digital data of high-resolution sound sources through a USB cable, the conventional transmission method causes a large uneven processing load on both the sending PC and the receiving USB DAC, which may result in problems such as sound interruption. However, "Bulk Pet" realizes stable data transfer by averaging the processing load on both sides to transfer a certain amount of data consistently. Since the sound quality also changes as the load status of the PC changes, you are able to select your preferred sound quality from four pre-set transfer modes.

    Bluetooth® multipoint connection for two

    The built-in Bluetooth® receiver engages connections with two difference devices at the same time. For example, when playing songs from a smartphone, the AI-303 can switch to another just like input source select without having annoying reconnection steps.
    * Simultaneous playback is not supported.

    Asynchronous mode to eliminate USB transmission jitter

    When used as a USB DAC, the AI-303 operates in asynchronous mode, where the input signal timing is regulated by the on-board clock, the connection with PC/Laptop and the AI-303 realizes purer digital signal transmission without affecting USB transmission jitters.


    High-quality analog volume with ladder type attenuator

    Unlike conventional volume circuit, the front volume circuit of the AI-303 is designed not to pass the music signal directly.
    By reading the value of the volume knob, the circuit reproduces the value with a resistive ladder type attenuator on the circuit board, thereby transmitting the music signal to the amplifier in the shortest path and maintaining the purity of the signal.
