【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.
[About clocks that synchronize time via radio waves]
The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.
Equipped with Infineon “MA5332M” new amplifier IC! It provides high sound quality and excellent audio performance with extremely high energy consumption efficiency.
BTL connection possible. Not only can it be used in stereo 170W + 170W, but it can also drive high power of 350W in BTL mode. Switch BTL mode and change A20a to monaural amplifier. Furthermore, by combining multiple A20a units and using an audio DAC that supports panoramic sound, you can create an optimal HIFI audio system that matches the speakers that are combined.
It can be used not only as a full-range amplifier, but also as an amplifier that independently drives a passive subwoofer. Switch the A20a to low-pass mode (also requires switching to BTL mode) and adjust the bass cutoff frequency from 70 to 200Hz.
Compatible with Bluetooth 5.0 input. With low latency and more stable wireless transmission, you can play music sources from various devices with Bluetooth output, such as smartphones, PCs, and laptops. With a maximum transmission distance of over 20 meters, you can enjoy the best music wirelessly anywhere in the room!
We are particular about the construction. Precisely machined from all-aluminum CNC process, to ensure good sound, the entire electrical circuit uses a large number of capacitors used in the professional audio field, and has comprehensive safety measures such as eddy current protection and thermal protection.
