Dual monaural drive digital integrated amplifier with YDA138 digital amplifier IC USB input DAC amplifier FX-AUDIO- YD-202J built-in (black)

【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. Equipped with tone control, loudness control, gain boost, and mute functions 3 systems (RCA/3.5mm/USB) input switching, electronic volume, USB-DAC, built-in headphone amplifier YAMAHA YDA138 digital amplifier IC x 2 dual monaural drive digital amplifier Dedicated remote control included as standard AC adapter required (sold separately) DC12V/2A DC jack 5.5mm x 2.1mm (center positive) This is a digital amplifier with a dual mono amplifier configuration equipped with two YAMAHA YDA138 digital amplifier ICs. USB-DAC function, 3-system input switching, electronic volume, tone control function, headphone amplifier, It is a multi-functional model equipped with loudness control and gain boost functions, and is a fun amplifier to play with. Completely designed in-house as a successor model that inherited the functions and sound quality trends of the Lepai LP-2020A+, which was originally sold by our company. However, as a result of collecting the opinions received from the sale of prototype lots, we have developed a dual monaural configuration. We have changed to a pure line concept that takes advantage of its characteristics, and have further evolved the sound quality and operability! This will be the 6th lot starting from May 7, 2021.
