The best re-amp box. The debate is finally over.

United’s Replay Box offers the very best performance and options for re-amplification. Whether you’re producing the most tone-savvy musician or experimenting with sound design, the Replay Box performs on a level all of its own — with an ultra-quiet design and flexible tone voicing. With two different custom transformers for two unique sonic fingerprints and all of the gain you need, the Replay Box raises the bar for all recordists.

The Definitive Vocal Microphone. The debate is finally over.

The UT Twin87 captures the essence of both the original classic and modern incarnations of the “87-style” microphone design. For the first time ever, United has created a microphone that duplicates both circuits, and can reconfigure itself on the fly for an exceptional reproduction of the sonic capabilities of both microphones. The UT Twin87 features our own large-core, custom-wound, US-made output transformer, our own custom made 24k gold sputtered dual diaphragm/dual backplate K87 style capsule, and a whole assortment of selected, premium components such as polystyrene, tantalum, multilayer ceramic, WIMA film capacitors, metal and carbon film resistors, and hand-selected transistors.
