A Bridge Between UA's Analog DNA and Modern Precision
Born from Universal Audio's expertise, the 710 Twin-Finity combines the warmth of UA's tube circuits with the speed of semiconductors. Designed and manufactured in California, it stands as a creative alternative to "neutral" preamps, offering authentic analog textures in a portable half-rack format.
For Creators Who Want to Choose Their Tone, Take After Take
Singers, producers, engineers, and multi-instrumentalists find a versatile ally here. Transparent for vocals and acoustic instruments, edgy for guitars, punchy for basses, it adapts to every microphone and source. The "blend" control allows you to align the sonic signature with your aesthetic, from precise modern sound to vintage thickness.
Features Tailored for the Modern Studio
In-Phase Tube/Transistor Blending
The two gain stages, perfectly in phase, mix to a common output. The "blend" potentiometer shifts from 100% tubes to 100% transistors, offering an almost infinite sonic palette and reproducible timbres.
Dynamic and Saturation Management
The dual "Gain/Level" control enables creative gain staging scenarios, similar to a guitar amplifier. The backlit VU meter switches to "Drive" mode to visualize input stage saturation in real time.
JFET DI and Professional Connectivity
The high-impedance JFET direct input preserves the attack and frequency range of instruments. Comprehensive XLR connectivity and the monolithic balanced output stage ensure professional-level output and controlled noise.
