【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. Adopts ES9023P manufactured by ESS Technology. Adopts ARM-based MCU for USB receiver Output coupling-less specification / Equipped with gain setting DIP switch High power headphone amplifier circuit with 3 operational amplifiers and 2 stages Bus-powered design also supports external power supply DAC series high-performance model with powerful headphone amplifier function and 3 high-resolution input systems This is a D/A converter and headphone amplifier product that uses ESS Technology's ``ES9023P'' as the DAC IC and Cirrus Logic's ``CS8416'' as the digital audio receiver. You can experience the sound quality of a high-performance DAC with a coupling-less design that provides straight, high-quality sound that is close to the original sound without any seasoning, making it as realistic as if you were playing the performance right in front of your eyes. In addition to USB, digital inputs include SPDIF optical input and coaxial input terminals, allowing you to switch between three digital inputs. The headphone amplifier has a two-stage configuration using three operational amplifiers, and the current amplification stage has independent left and right configurations, achieving high sound quality with good channel separation and high power output that can drive high-impedance headphones.
