------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ AC adapter required (sold separately) DC12V/2A or higher DC jack 5.5mm x 2.1mm (center positive) 12AU7 (ECC82) vacuum tube adopted High power output & high quality headphone amplifier circuit Electronic volume with low distortion and low output noise Equipped with an OLED display that allows complex setting operations! TUBE series High-performance model of vacuum tube preamplifier and headphone amplifier 12AU7 (ECC82) A fusion of vacuum tube preamp and high power headphone amplifier! This is a preamplifier and headphone amplifier product that allows you to switch the vacuum tube preamplifier stage ON/OFF. The front stage amplifier circuit is equipped with a vacuum tube amplification stage using 12AU7 (ECC82) vacuum tubes, followed by the NJW1194 electronic volume IC with tone control function, which achieves high sound quality with a low distortion and low noise design. The amplification stage consists of a headphone amplifier circuit that focuses on drive power using power transistors. The headphone amplifier circuit enables high-power output, maximizing the potential of the headphones with powerful drive power, and allowing you to experience the pleasant and heart-shaking sound created by the addition of overtones from vacuum tubes. You can also add it to your existing stereo system as a preamp, and if you turn on the tube preamp, it will add the characteristics of a vacuum tube and produce a pleasant sound. Equipped with TREBLE/BASS tone control, you can set the sound quality to your preference. The RCA output is linked to the volume control, and can be used as a preamp by connecting it to an amplifier, etc. The volume settings for the RCA output and headphone output can be set independently, so there is no need to change the volume settings every time you switch output destinations. Equipped with an OLED display on the front panel, it also supports advanced settings and operation with the included remote control. The setting menu screen displayed on the display not only allows volume control and vacuum tube operation mode switching settings, but also a wide range of settings such as tone control, display brightness, and automatic display OFF function.
