Convenient and easy-to-use USB power supply. *The USB terminal is for power supply only. It cannot be as a USB-connected DAC. Ultra-compact and incredibly easy to use, yet delivers high-quality sound! Don't compare it to just any converter! With the widespread adoption of devices equipped with optical digital outputs, such as TVs, game consoles, and digital players, and the decline of devices with traditional analog outputs, there is a growing demand for a device that converts optical digital output to analog RCA output, allowing users to easily connect to audio equipment and enjoy high-quality sound. This D/A converter product, developed with three core concepts in mind—small size and compactness, ease of use, and high sound quality—is specifically designed for optical digital signals. Simply connect it to a USB port using the included USB cable to operate it, and then connect it to a playback device such as a player or TV using the optical digital cable. You can then enjoy high-quality sound by connecting the output to a soundbar, amplified speakers, or audio amplifier. This product is a compact D/A converter compatible with high-resolution audio sources (24-bit/192kHz), featuring an ESS Technology ES9018K2M DAC IC and an optical digital input terminal. By limiting the interface to optical digital input, this compact, single-function, high-quality D/A converter achieves thorough miniaturization while delivering sufficient sound quality for an audio product. The power connector is a highly versatile USB (Type-C) terminal, and it operates on a 5V USB power supply. Since it operates simply by connecting it to a USB port using the included USB cable, you can use it anywhere, powered by AC-USB adapters commonly for mobile phone chargers or USB ports on TVs, etc. In particular, it can be conveniently as a digital-to-analog converter (optical digital input → RCA stereo output) to convert the optical digital output of TVs and game consoles to high-quality analog, and connect to audio amplifiers, speakers with built-in amplifiers, soundbars, etc. [Main IC Specifications] ■DAC IC: ES9018K2M manufactured by ESS Technology DAC IC for high-end audio Dynamic range: 127dB THD+N: -120dB ■ Differential conversion section operational amplifier: STMicroelectronics TL062 [Notes] *The USB port is for power supply only.
