מָבוֹא

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.

ה 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.

הוראות הפעלה

  1. הפעלה/כיבוי: Press the power button located on the front panel to turn the amplifier on or off. A built-in mute circuit prevents 'POP' noise during startup and ensures the tubes operate optimally.
  2. התאמת עוצמת הקול: 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.
  3. מד VU: 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.
  4. חימום צינור: Allow a few moments after powering on for the tubes to warm up and stabilize for optimal sound performance.
