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.
の 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.

操作手順
- 電源オン/オフ: 前面パネルにある電源ボタンを押して電源を入れます。 amplifier on or off. A built-in mute circuit prevents 'POP' noise during startup and ensures the tubes operate optimally.
- 音量調整: 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 メーター: 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.
- チューブのウォームアップ: Allow a few moments after powering on for the tubes to warm up and stabilize for optimal sound performance.

メンテナンス
- クリーニング： 定期的に拭き取ってください amplifier's exterior with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials, as they may damage the finish.
- チューブの交換: 12AU7 amplification tubes are pluggable, allowing for replacement. If you notice a degradation in sound quality or tube failure, consult a qualified technician or refer to specific tube replacement guidelines. Ensure the amplifier is powered off and unplugged before attempting any tube replacement. Only use compatible and matched tubes.
- 換気： 確実に amplifier has adequate ventilation to prevent overheating. Do not block the ventilation grilles.
トラブルシューティング
- サウンド出力なし:
- 確認してください amp電源がオンになり、電源インジケータが点灯します。
- Verify all audio cables (input and headphone) are securely connected.
- Ensure the volume knob is not set to minimum.
- Confirm the audio source is active and playing.
- 歪んだ音:
- 両方の音量レベルを下げます ampライターとオーディオソース。
- Check if the headphone impedance is within the suitable range (16Ω~600Ω).
- オーディオ ケーブルに損傷や接続の緩みがないか検査します。
- Consider if the tubes might need replacement if distortion persists and is not related to volume or connections.
- 電力の問題:
- If the unit does not power on, check the AC power cable connection and the wall outlet.
- 正しい巻を確認してくださいtage (110V or 220V) is supplied to the unit.
