소개
The KGUSS xDuoo TA20 Plus is a desktop balanced tube headphone amplifier designed to deliver high-fidelity audio. It features a hybrid "Tube + Transistors" structure, utilizing two 12AU7 tubes for signal amplification in the pre-stage and high-quality transistors for a Class A buffer in the post-stage. This design aims to combine the delicate and soft vocal characteristics of tubes with the dynamic power and speed of musical instruments.
그만큼 amplifier boasts comprehensive input and output interfaces, including two RCA and one XLR balanced input, along with 6.35mm unbalanced, 4.4mm balanced, and 4-pin balanced headphone outputs. Its fully balanced circuit design from input to output significantly enhances crosstalk, resolution, and signal-to-noise ratio (SNR), providing an unparalleled listening experience. The TA20 Plus is suitable for driving a wide range of headphones with impedances from 16Ω to 600Ω.

작동 지침
- 전원 켜기/끄기: 전면 패널에 있는 전원 버튼을 눌러 전원을 켜세요. amplifier on or off. A built-in mute circuit prevents 'POP' noise during startup and ensures the tubes operate optimally.
- 볼륨 조절: Use the volume knob on the front panel to adjust the output level. The amplifier incorporates digital volume adjustment chips to maintain balanced left and right channels, even at low volumes.
- VU 미터: Observe the retro mechanical VU meter on the front panel, which displays the output level in real-time. The pointer will move in rhythm with the music.
- 튜브 워밍업: Allow a few moments after powering on for the tubes to warm up and stabilize for optimal sound performance.
