From 100% Tube Sound to 100% Solid State Sound — Mic Preamp with Tone Blending and DI BoxThe 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 FeaturesPreamp 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 DesignThe 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 ApplicationsThe 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.

Functionality and ConvenienceTwo Gain Stages: Gain and level adjustments allow for different tonal shades, from warm to crunchy.

Direct Input JFET: Discrete DI block with Ultra Hi-Z input at 2.2MΩ impedance.

Monolithic, Balanced Output Stage: Ensures clean and precise signal processing.

VU Meter with “Drive” Mode: Illuminated VU meter shows input drive levels.

Easy Mounting and Use: Rackmountable, portable design for studio, desk, or stage use.
