---------------------------------------------------------------------- 【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. ----------------------------------------------------------------------

AC adapter required (sold separately): DC12V/2A or higher DC jack 5.5mm x 2.1mm (center positive) Sound quality comparable to that of a high-end amplifier Fully Digital Amplifier Adoption of SA9123L enables USB input to support high-resolution 24-bit/192kHz audio Equipped with 3 digital inputs (high-resolution compatible) and 1 analog RCA input High-quality electronic volume and tone control Nichicon KT series audio capacitors are used for the power supply decoupling capacitors This is a high-quality, fully digital amplifier that minimizes sound quality degradation along the signal path by transmitting digital signals all the way from the input terminal to the digital amplifier IC. Based on the high-resolution compatible full digital amplifier product "D302J+", this high-end model uses the new generation SAVITECH BRAVO-HD "SA9123L" as the USB receiver chip, and supports up to 24bit/192kHz via USB connection.
