What does this device do?

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.

Can I use RCA and XLR outputs simultaneously?

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.

How do I reset EQ frequencies to neutral?

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.

What tubes can I upgrade to?

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.
