【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】
■ Voltage Compatibility
This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).
Many regions use 120V or 220–240V.

・Use without a transformer
・Plug incompatibility
・Damage caused by improper setup or usage
■ Liability
We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.
■ Final Notice
