■Connect to your TV with a single HDMI cable
Connecting the TV and AI-303 only requires an HDMI cable. Then, by combining it with your favorite speakers, you can easily upgrade the sound of your TV. Since it supports ARC/eARC and HDMI CEC, you can also control the AI-303's volume and on/off with the TV's remote control. Its small size means you won't have trouble finding a place for it around your TV.
If your TV supports it, you can also enjoy high-resolution quality playback up to 192kHz/24bit.

*Please use an HDMI cable that supports "HDMI2.1" and "Ultra-High Speed".
*Please set the digital output to "PCM" in the TV's output settings.
*The HDMI terminal is exclusively for the HDMI (ARC) terminal of TVs that support ARC (Audio Return Channel) or eARC (Enhanced Audio Return Channel), so HDMI connection with devices other than TVs is not possible.
The supported signal is only 2ch PCM signal.
It does not support 5.1ch or Dolby Digital signals, so please be sure to set the TV's output to 2ch PCM before use.

■Supports 11.2MHz DSD native playback and 384kHz/32bit high-resolution (HD) audio sources
You can fully enjoy high-resolution audio sources of studio master quality that surpass CDs, with their original sound quality. The DAC's operating mode features two types of digital filters and up-conversion functions of x2Fs, x4Fs, and x8Fs, allowing you to pursue your preferred sound quality.

■Equipped with various digital inputs such as HDMI, USB-C, OPTICAL, and COAXIAL
Digital connection is possible with various devices, such as TV via HDMI, PC via USB, and existing CD players via OPTICAL/COAXIAL, and the high-performance DAC will maximize the performance of each source.

■Adoption of USB-C terminal as USB DAC input facilitates connection with smartphones and tablets
In addition to being used as a high-quality USB DAC when connected to a PC, it can also be used as a USB DAC by connecting to a wide range of devices that support USB Audio Class 2.0, such as smartphones, tablets, and DAPs.
The AI-303 is equipped with a self-powered USB-C terminal, and if connected with C-type terminals, it can automatically identify the host and device and be used as a USB Audio Class 2.0 audio device. It can be directly connected to most Android devices and recent iPad Airs and iPad Pros equipped with USB-C terminals.

*A separate USB camera adapter is required for iPhone connection.
