【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.

[Recording studio-level resolution] The ESS9038Q2M chip spins a silent background of over 121 dB. The 0.0007% distortion-free sound path protected by the op-amp OPA1678 transmits the texture of the bow rubbing on a classical record, the husky voice reverberating in a jazz live performance, and the warmth of an analog synth. Here's why it's chosen by music college professors as a teaching material for teaching students "three-dimensional expression of sound" and as a reference equipment used by studio engineers for mastering checks.
[A versatile driving station for headphone collectors] From 32Ω in-ear IEMs to 600Ω open headphones, the 560mW power reserve will awaken any beloved device. Enjoy late-night earphone listening in low gain mode, or daytime headphone blast sessions in high gain mode. Anime nerds can amplify the impact of battle scenes with bass boost, and audiobook lovers can catch the narrator's breathing in bypass mode. Dual output allows you to watch with friends at the same time.
[Precision tool for sound creators] The tone control, which can be fine-tuned by ±6dB from the neutral setting at 3 o'clock, is perfect for rock band bassists to adjust the low sound pressure of live sound sources and podcasters to optimize their voice quality. Dual Type-C/USB-A power supply ensures stable operation in a bus case on the go or in an audio rack at home. When connecting multiple devices in a recording studio, optical output provides noise-free transmission.
[Functional beauty recognized by designers] The machined aircraft aluminum body blends in with the modern interior of coworking spaces. The colorful LED display can be used as a visual aid to distinguish formats during blind tests. The one-handed rotary knob is also ideal for adjusting the volume while playing an instrument. It demonstrates its functional beauty in any situation, whether as a teaching tool in a music university lecture hall or as a central controller in a gaming room.
