Themis V2

[ VERSION  2 ]

What is Themis - [ VERSION 2 ]

Introducing the evolution of analog excellence – Themis V2 transcends its predecessor to become a truly universal audio buffer. This sophisticated device seamlessly bridges the gap between professional and audiophile equipment while delivering reference-grade headphone amplification.

Universal Signal Architecture: • Pristine balanced/unbalanced conversion • Professional-grade unity gain buffering • Dual-format headphone amplification • Automated voltage regulation system

Powerful Headphone Performance: The dual amplification stages deliver an impressive 3.5W of pure analog power, ensuring absolute control over any headphone load. Whether you’re using studio monitors or audiophile headphones, both 6.3mm and 3.5mm outputs provide identical, uncompromised performance.

Professional Signal Control: At the heart of Themis V2 sits a precision ALPS stepping potentiometer, offering exact volume adjustments with perfect channel tracking. The interchangeable operational amplifier architecture allows fine-tuning of the sonic signature to match your preferences.

Advanced Features: • Automated voltage regulation for consistent performance • Zero-gain buffer mode for ultimate transparency • Balanced and unbalanced connectivity • Professional-grade signal conversion circuitry • Dual discrete amplification stages

Perfect Integration: • Professional recording studios • Audiophile listening rooms • Home studio setups • Reference monitoring systems

Themis V2 represents the pinnacle of analog interface design, where professional functionality meets audiophile performance. Whether converting signals, driving headphones, or serving as a transparent buffer, it maintains absolute signal integrity at every stage.
