【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.
Equipped with the latest XMOS XU316 chip, the core of high-quality sound reproduction: Supports ultra-high resolution DSD512/PCM768kHz: The U2 PRO, equipped with the latest XMOS XU316 asynchronous transmission, guarantees virtually no delay and a stable signal, enabling native playback of ultra-high resolution audio sources such as DSD512 and PCM 32bit/768kHz, which was difficult with conventional USB interfaces. By minimizing delay in USB transmission and achieving stable data transfer, it delivers high-definition sound that faithfully reproduces even the smallest details of the sound.
Simultaneous supply of three independent digital outputs: Dramatically expands the connectivity of your DAC or amplifier: It provides three types of digital outputs simultaneously: optical, coaxial, and I2S (via HDMI interface). This makes it easy to connect music from your PC or smartphone to older, high-end DACs and AV amplifiers that do not have a USB input. If you have a high-performance DAC that supports I2S input, you can expect even higher purity signal transmission and improved sound quality.
UAC mode switching function for compatibility with a wide range of devices, from games to high-resolution audio: Easily switch between UAC (USB Audio Class) modes with the switch on the back. In UAC 1.0 mode, it is instantly recognized by game consoles such as PS5 and Switch, and in environments where driver installation is difficult, allowing for plug-and-play use. Switching to UAC 2.0 mode allows you to take full advantage of the functions of high-resolution audio playback on your PC.
Clock-upgradable design for advanced users: Despite its compact, postcard-sized body, it features space on the circuit board for replacing the clock oscillator. By replacing it with a higher-precision oscillator with less jitter (time-axis fluctuation), it leaves room for further sound quality improvement, satisfying the demands of audiophiles (soldering skills are required for replacement).
Compact and intuitive operation: Easy setup with USB power supply: Operates on USB bus power, eliminating the need for a cumbersome AC adapter. The included USB Type-C cable (compatible with both A and C) allows direct power supply from PCs, mobile devices, PS5 USB ports, etc. The front indicator clearly shows the current audio format (PCM/DSD), making it a simple yet high-performance digital audio enhancement device.
[Introduction] Are you fully unlocking the true potential of the music stored on your PC, smartphone, or game console? The Nobsound U2 PRO acts as a bridge, converting the USB output of these devices into higher-quality digital signals (optical/coaxial/I2S). It's the perfect first step to experiencing clearer, more immersive sound than ever before with your favorite DAC or amplifier.
