----------------------------------------------------------------------
【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.
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.
[Changes from 5th lot to 6th lot]
Change the capacitor of the output stage LPF circuit
