From 100% Tube Sound to 100% Solid State Sound — Mic Preamp with Tone Blending and DI Box

The award-winning 710 Twin-Finity™ preamp from Universal Audio is a modern design that offers both classic, retro tube warmth and clear, transient-enhanced solid-state sound, all in a compact 2U half-rack form. The 710 is a versatile preamp that stands out from typical preamps found in audio interfaces, inspiring with its tonal flexibility. With its smooth tone blending control, from 100% tube to 100% solid-state, users can achieve an infinite palette of sounds and easily find their unique tone. On the market, you can find many affordable solid-state and tube preamps, but only the 710 offers the best of both worlds — and everything in between — in one unit, without breaking the budget of a serious project studio owner.

Key Features

• Preamp from Putnam’s 610 Console and DI Box: Legendary, fully tube sound at a price suitable for project studios.
• Tone Blending Function: Allows mixing signals from tube and solid-state paths, offering an infinite palette of sounds.
• Versatility and Flexibility: Provides maximum tonal diversity with gain, level, and impedance adjustments.
• Robust Construction: Durable metal housing ensures reliability in the studio and on stage.

Innovative Circuit Design

The key to tonal freedom is the innovative circuit design, where a solid-state, transimpedance input amplifier simultaneously drives separate, phase-aligned gain stages — tube and solid-state — with the signal summed at the output. Using the “∞” control, you can smoothly blend the signals from the solid-state and single-ended Class A tube paths, achieving an infinite palette of preamp tones and quickly finding your distinctive sound.

Versatility and Applications

The 710 is perfect for use with a variety of microphones, and the discrete component-based JFET DI input allows connection of any electric instrument. Guitarists and bassists will especially appreciate the ability to connect both active and passive pickups. The 710 Twin-Finity comes with a 19” rackmount kit for one or two units.
