【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. Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.

■ Plug Type This product uses a Japanese plug (Type A or B). A plug adapter may be required depending on your region.

■ Transformer Requirement (Very Important) A transformer is required for safe use.

A plug adapter only changes the plug shape and DOES NOT convert voltage. Using this product without a transformer may cause serious and irreversible damage.

■ Buyer Responsibility As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.

■ No Return / No Refund Policy We do NOT accept returns or refunds for: ・Voltage mismatch (including 120V and 220–240V environments) ・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 Please ensure full understanding of the above before purchasing. Use only under the correct voltage environment. [Hybrid Design of Vacuum Tubes and Solid State] In the first stage, a 6J2 vacuum tube amplifies the signal and adds analog warmth, while in the second stage, a low-noise op-amp ensures DC stability. This suppresses the "high-frequency metallic noise" that is a problem when connecting to digital devices. In actual measurements, when connected to an iPhone 15, the distortion rate in the 10kHz band improved from 0.15% to 0.08%. The vacuum tube is compatible with six types, including 6K4/6J1/GE5654, allowing users to customize the tone to their liking. [Scene-Adaptive Gain Control System] Equipped with a 3-stage gain switch (39dB/42dB/45dB) to accommodate the output difference of MM cartridges (typically 2.5-6mV). For example, it is designed to be optimized for low-output MM cartridges (Ortofon 2M Red: 5.5mV) at the 42dB setting. When using AUX input, it switches to direct mode in the "OFF" position, allowing line signals (typically 600mV) from TVs and DACs to pass through without attenuation. Even sudden loud noises when connecting game consoles do not distort, and THD is maintained even with the explosion sound effect of the PS5 (150Hz band).
