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.
די 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.

סעטאַפּ אינסטרוקציעס
- מאַכט קשר: Connect the supplied AC power cable to the amplifier's power input and then to a suitable wall outlet (AC 110V or 220V, depending on your region).
- אַודיאָ מקור קשר:
- פֿאַר RCA אַרייַנשרייַב, connect your audio source (e.g., CD player, DAC) to the RCA input jacks on the rear panel.
- פֿאַר XLR באַלאַנסט אַרייַנשרייַב, connect your audio source to the XLR balanced input jack on the rear panel.
- כעדפאָון קאַנעקשאַן: Connect your headphones to one of the available output jacks on the front panel:
- פֿאַר 6.35mm unbalanced headphones, use the 6.35mm jack.
- פֿאַר 4.4mm balanced headphones, use the 4.4mm balanced jack.
- פֿאַר 4-pin XLR balanced headphones, use the 4-pin XLR balanced jack.

אַפּערייטינג ינסטראַקשאַנז
- מאַכט אויף / אַוועק: 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.
- באַנד אַדזשאַסטמאַנט: 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 מעטער: 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.
- רער וואַרעם-אַרויף: Allow a few moments after powering on for the tubes to warm up and stabilize for optimal sound performance.
