【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.
The Fosi Audio V3 2.0 channel amplifier is built with high-quality components, including Japan Sumida inductors, Black Gate and WIMA capacitors, and ELNA miniature aluminum electrolytic capacitors, ensuring reliable and stable performance. Thanks to these components, the V3 stereo amplifier offers more precise control and more efficient power handling, delivering a superior audio experience.
300W x 2 Output Power: The Digital Amplifier V3 is equipped with the TI TPA3255 Class D power amplifier chip. This highly compatible chip is suitable for a wide range of audio applications, from stereo systems to home theater setups, and is easy to use for everyday use. With an SNR of ≥ 110dB and THD of ≤ 0.003%, it produces virtually imperceptible noise.
RCA inputs, speaker outputs, and 3.5 mm pre-outs: The Class D amplifier V3 boasts several innovative design features, including a tapered A volume control knob. For example, the amplifier body is equipped with ventilation holes for efficient cooling. Furthermore, thanks to its energy-saving mode, both the amplifier and its components have a longer lifespan.
Op-amp Chip Customization: The V3 HiFi amplifier comes with two interchangeable plug-in NE5532 op-amps. You can replace them with LME49720HA/MUSES02 120-140/OPA26041P/OPA2134PA 25-35/LM4562/NJM4556AD op-amps to better suit your preferences and specific musical types.
Peace of Mind Guarantee: Enjoy peace of mind with the V3 stereo amplifier. It comes with a 24-month warranty, guaranteeing reliable performance and customer satisfaction. *Note: The V3 is not an integrated amplifier, so the "pre-out" level is not controlled by the volume knob. Therefore, the volume cannot be adjusted when connected to the "pre-out".
The package includes a DC 32V 5A power adapter that limits the maximum output to 125W. To achieve the advertised maximum power of 300W, you will need to upgrade to a DC 48V 10A power adapter. The orange knob for the V3 is sold exclusively on the official website. If you wish to purchase it, please visit the official website at "https://fosiaudioshop.com".
1) Before using this product, please check that all cables are connected correctly. 2) This product uses a Taper A volume potentiometer, and the volume increases exponentially. 3) To turn this product on/off, please use the volume knob on the product itself. We do not recommend operating it directly at the power outlet.
[※] For better heat dissipation, we recommend using a Fosi Audio cooling fan (sold separately) with the amplifier.
This compact stereo amplifier is perfect for enjoying your favorite music. You'll love the Fosi Audio V3's easy installation and powerful sound output.
