Welcome to The Cool Life! I am a seller in Japan. I ship authentic products from Japan. Please enjoy shopping with peace of mind! You will find great products!

【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 high-end amplifiers full digital amplifier USB input supports high resolution 24bit/192kHz by adopting SA9123L Equipped with 3 digital inputs (high resolution compatible) + 1 analog RCA input High-quality electronic volume and tone control function Nichicon KT series audio capacitors are used as power supply decoupling capacitors. This is a high-quality full digital amplifier that minimizes sound quality deterioration along the route by transmitting digital signals from the input terminal to the digital amplifier IC. Based on the high-resolution fully 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 with USB connection.
