----------------------------------------------------------------------
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

High-efficiency, clean sound 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, the DP-1000 delivers up to 50W of power at 4Ω speakers, powerful enough to drive most bookshelf speakers on the market. With low distortion (0.03%) and a wide frequency response (20Hz-20kHz), it reproduces clean, distortion-free sound, from the subtle nuances of music to the powerful sound of movies. It's the perfect power for desktop or space-saving audio setups.
Seamless connection to various audio sources with Bluetooth 5.0 and AUX input: Built-in Bluetooth 5.0 allows for comfortable wireless music streaming from smartphones, tablets, and PCs. Connection is simple, and the Bluetooth name is "Nobsound TONE." It also features a 3.5mm AUX input jack, allowing for flexible connection to TVs, game consoles, and other audio sources you prefer via wired connections. Combining the convenience of both wireless and wired connections, it can be used to suit a variety of lifestyles and situations.
Intuitive Encoder Knob Operation & Visual LED Indicator: Instead of a standard volume knob, the unit uses a bidirectional, infinitely rotatable encoder knob. Its light and easy operation makes fine adjustments easy. The front LED indicator lights up in conjunction with the knob's rotation, allowing you to visually grasp the current volume level, making operation easy even in dark places. It also lights up when the maximum or minimum volume value is reached. This user interface is simple yet sophisticated.
Compact Aluminum Alloy Housing & Reliable Protection Circuits: The amplifier's body is made of aluminum alloy for superior heat dissipation, reducing heat generation and maintaining stable operation even during extended use. Its dimensions are just 78x70x32mm and it weighs approximately 129g, making it extremely compact. While small enough to fit anywhere, it features multiple built-in protection circuits to protect the amplifier from overloads, short circuits, and overheating, ensuring the safety of both the amplifier and connected speakers.
"Big sound in small spaces." The passion of the developer: In 2018, a young engineer living in a small one-room apartment in Tokyo faced a problem: high-quality audio systems took up too much space. At the time, mainstream amplifiers were large, taking up space on his desk, and organizing the cables was a pain every time he moved. He began development with the concept of a palm-sized amplifier with 50W output. The seventh prototype successfully combined the TPA3116 chip with aviation aluminum. After raising funds on Kickstarter, he received numerous user feedback, including examples of how the amplifier can be used in conjunction with a projector to watch movies while traveling and to save space in the study. Today, under the slogan "Real-quality sound in small spaces," the product is supported by both urban dwellers and outdoor enthusiasts.
