## Questions & Answers

**Q: What does this device do?**
A: T8 can compensate for the defects of speakers and sound field by adjusting 7-band high, middle and low frequencies, and modify various sound sources. The timbre and loudness also can be changed to achieve different sound effects.

**Q: Can I use RCA and XLR outputs simultaneously?​​**
A: Yes! Both outputs work concurrently - connect XLR to studio monitors and RCA to a subwoofer simultaneously. Ideal for multi-amp setups without signal degradation. Perfect for A/B testing or expanding your audio chain.

**Q: How do I reset EQ frequencies to neutral?​**
A: Rotate any band's knob until you feel a tactile pause at the center position (scale line vertical). This zero point means no boost/cut applied. Reset all knobs to center for flat reference response.

**Q: What tubes can I upgrade to?**
A: Stock 6H1N-BN tubes support direct swaps with 6N1/6AQ8/ECC85. For 6SN7GT tubes, you MUST use a 6SN7-to-6N1 adapter (not included). Adapter ensures proper pin alignment and voltage safety.

## Customer Reviews

### ⭐⭐⭐⭐⭐ イージーリスニングな音にしてくれる
*by バ***作 on December 9, 2024*

非AmazonのECで購入。（取扱ショップはNob sound）すごく懐かしい感じの音です。ハッキリ言うとDAC→パワーアンプセクションの直結に比べると解像感そのものは下がる。でもアナログ時代の聴き心地を提供してくれます。音の密度は増しバスドラムから本来出している低音がドスドス迫ってくるような音像。耳に刺さる音のカドが取れ、弾力を感じる。真空管プリの中には定位感を変えてしまうような物があると思いますがそういう野暮さは見えず、EQの効きもほどほどで極端なセッティングをしても音源の持ち味が損なわれるには至らない。真空管アンプですがこれといってハムノイズ等の弊害は無し。とはいえ個体差がある可能性は否めず。耐久性については到着直後なのでわかりません。何時間でも鳴らしっぱなしにしてしまいそうな心地良さがあります。
