Universal Audio 710 Twin-Finity Microphone Preamplifier

Single-Channel Dual-Path Preamp

The Universal Audio 710 Twin-Finity is a single-channel microphone and line preamplifier with an integrated instrument direct-inject input. Its dual-path architecture combines a high-voltage vacuum tube stage with a solid-state circuit. A front-panel blend control allows continuous mixing between the two signal paths. The design targets engineers and musicians seeking flexible tonal shaping in a compact desktop format.

Tube Warmth With Solid-State Clarity

The preamp replaces single-topology units that offer only tube coloration or only transparent gain. The tube circuit runs a 310V single-ended Class-A triode stage phase-aligned with a solid-state gain stage. The jump is worth it when a session demands both harmonic richness and clean headroom without patching multiple devices. Variable input and output controls plus the blend knob deliver an extensive range of gain structures from one channel.

Studios Needing One Channel Of Hybrid Tone

This unit suits project studios and home recordists who want tube and solid-state flavors in a single insert point. It also fits producers tracking guitars or basses directly via the discrete JFET DI. Buyers requiring multiple simultaneous preamp channels should look elsewhere. Sessions needing remote gain recall or digital connectivity will not find those features here.
