Refine speaker performance and modify any audio sources and compensate channel imbalances.
Delivers noise-free signal transmission with enhanced separation for pristine sound reproduction.
Can be changed to the following models: 6N1/6AQ8. 6SN7GT requires a 6SN7 to 6N1 socket adapter.
Instantly toggle between CH1 and CH2 sources. Two outputs (RCA+XLR) can work at the same time.
Boosts signal integrity and refines tonality before amplification, revealing hidden details.
Minimizing coloration for critical near-field monitoring.
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.

## Features

- Professional 7-band equalizer (50Hz-16KHz) precisely adjusts highs/mids/lows to compensate speaker defects & optimize any sound source, delivering custom audiophile-grade acoustic profiles.
- Dual XLR/RCA inputs & outputs with balanced signal transmission eliminate interference noise, while independent channel balance control ensures accurate stereo imaging.
- Upgradable 6H1N-BN vacuum tubes generate warm HiFi analog sound signature; pluggable sockets support ECC85/6SN7GT tubes for personalized timbre sculpting.
- CH1/CH2 input switching & simultaneous RCA/XLR output modes enable flexible connectivity with amplifiers/active speakers, simplifying studio-grade setups.
- Compact aluminum chassis with EMI-shielding iron plate fits desktops seamlessly, featuring vintage tube glow for both aesthetic appeal and noise-free performance.
