【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. High-efficiency clean sound with 50W x 2 power delivered by the TPA3116 Class D amplifier: Equipped with the Texas Instruments TPA3116 Class D amplifier chip, known for its high efficiency and low heat generation. Despite its compact body, it delivers a maximum output of 50W x 2 with 4Ω speakers, powerfully driving many commercially available bookshelf speakers. With low distortion (0.03%) and a wide frequency response (20Hz-20kHz), it reproduces clean, low-distortion sound from the subtle nuances of music to the powerful sound of movies. It has the perfect power for desk setups and space-saving audio setups. Seamless connectivity with various audio sources via Bluetooth 5.0 & AUX input: Built-in Bluetooth 5.0 enables comfortable wireless music streaming from smartphones, tablets, and PCs. Connection is simple; the Bluetooth name is "Nobsound TONE". It also features a 3.5mm AUX input terminal, providing flexible connectivity to TVs, game consoles, and other audio sources that require a wired connection. Combining the convenience of both wireless and wired connections, it can be used in a variety of lifestyles and situations. Intuitive Encoder Knob Operation & Visual LED Indicator: Instead of a conventional volume knob, it employs a bidirectional, infinitely rotatable encoder knob. Its smooth operation makes fine adjustments easy. The front LED indicator lights up in conjunction with the rotation, allowing you to visually see the current volume level, making it easy to operate even in dark places. The light also indicates when the volume has reached its maximum or minimum value. It's a simple yet highly sophisticated user interface. Compact Aluminum Alloy Casing & Reliable Protection Circuitry: The body is made of aluminum alloy with excellent heat dissipation properties, suppressing heat generation even during prolonged use and maintaining stable operation. Its size is just 78x70x32mm and it weighs approximately 129g, making it extremely compact. Despite its small size, which allows it to be placed anywhere, it incorporates multiple protection circuits to protect the equipment from overload, short circuits, and overheating, ensuring the safety of both the amplifier and connected speakers. "Loud sound in a small space." The developer's passion: In 2018, a young engineer living in a small studio apartment in Tokyo faced a problem: "High-quality audio systems take up too much space." Amplifiers that were mainstream at the time were large, taking up desk space, and he struggled to organize the wiring every time he moved. He started development with the concept of "50W output in a palm-sized device." With his seventh prototype, he succeeded in combining the TPA3116 chip with aircraft-grade aluminum. After raising funds on Kickstarter, he received numerous reports from actual users about how they are using it, such as "watching movies with a projector while traveling" and "saving space in a study." Currently, with the slogan "Authentic sound even in small spaces," it is supported by both urban dwellers and outdoor enthusiasts. specification Brand: Nobsound Model: TONE Input terminals: AUX/Bluetooth Output terminal: Banana plug AUX input sensitivity: 0.775V THD+N: 0.03% SN ratio: ≧93dB Frequency response: 20Hz-20KHz (±2.5dB) Maximum output: 50W x 2 (4Ω) Supported impedance: 4-8Ω Operating voltage: DC 12-24V External dimensions: 78 x 70 x 32 mm Weight: 129g Package weight (excluding power supply): 250g Package weight (19V power supply included): 400g Contents included 1 x TONE Amplifier Unit 1 x DC 19V power adapter (optional)
