What customers say
The Universal Audio 710 consistently earns acclaim for its exceptional versatility and robust build quality. Its defining strength is the innovative TWINfinity design, allowing users to seamlessly blend 100 percent solid state circuitry for clean punch with 100 percent tube circuitry for classic warmth and harmonic richness. This blend feature lets engineers precisely tailor the preamp character for any source, from vocals to drums. Users consider the 710 an indispensable workhorse, effectively replacing the need for two specialized preamps and offering significant value. While mastering the blend knob requires some attention, the consensus confirms the 710 delivers professional sound and UA reliability in one unit.
Know before you buy
The 710 TWIN features a unique blend knob that allows you to continuously vary the signal between 100% tube and 100% solid-state circuitry. This lets you dial in anything from the harmonic richness and saturation of a tube preamp to the clean, punchy transparency of a solid-state design.
Yes, it is highly versatile. The dual-channel design is excellent for capturing vocals, acoustic guitars, or even DI instruments like bass and electric guitar, giving you the flexibility to match the preamp's character to the source material.
The 710 TWIN is designed as a desktop unit, making it ideal for smaller studio setups or portable recording rigs. It does not require a rack-mount kit to function, though it can be integrated into a rack system with the appropriate mounting hardware.
Having two channels allows you to record stereo sources, such as a pair of overhead microphones for drums or a stereo acoustic guitar setup. It also provides the convenience of having two distinct signal paths ready for tracking a singer-songwriter simultaneously.
You should verify that all knobs and switches operate smoothly without crackling and ensure the tube is seated correctly. It is also good practice to test both channels with a microphone and a line-level source to confirm consistent gain and signal integrity.
