United Studio Technologies UT Twin48 Twin Mode Tube-Driven Large Diaphragm Condenser Microphone

What Is the United Studio Technologies UT Twin48 and Why It’s a Must-Have Microphone
The United Studio Technologies UT Twin48 is a tube-driven large-diaphragm condenser microphone that combines the best qualities of two classic vintage microphones, the 47 and the 48. With its two operating modes, this microphone offers versatility that no other mic in its class can match. Whether you're capturing vocals, instruments, or voiceovers, the UT Twin48 delivers bold, rich sound with exceptional clarity, making it the ideal choice for studios looking for an all-in-one microphone that covers a wide range of applications. Built with a focus on quality and performance, the UT Twin48 brings legendary sound to your mic locker.

Dual Operating Modes for Maximum Versatility
One of the most unique features of the UT Twin48 is its dual-mode operation, which allows you to switch between two distinct sounds that each mic design (47 and 48) is known for. In 47 Mode, you have the option of cardioid and omnidirectional patterns, delivering an open, detailed sound with greater sensitivity, perfect for a bigger, more ambient capture. In 48 Mode, the mic offers cardioid and figure-8 patterns, providing a warmer, more intimate tone, ideal for capturing focused sounds with less background interference. Each mode delivers a different tonal character, giving you more options and greater control over your recordings.

Classic Tube Sound with Modern Refinements
The UT Twin48 features a select new old stock (NOS) EF86 pentode tube, which is the last remaining descendant of the original tubes used in classic microphones of the ‘40s and ‘50s. This tube offers a rich, harmonic profile that produces bold, full-bodied sound with exceptional clarity and low noise. Coupled with the custom-designed UT-BV8 transformer, made to the original Braunbuch specifications, the UT Twin48 offers a level of detail and warmth that’s rare in modern microphones. The transformer’s high-nickel alloy laminations and copper Faraday shield help eliminate interference, ensuring a clean signal for every recording.

High-Performance Power Supply for Consistent Sound
A tube microphone’s performance is only as good as its power supply, and the UT Twin48 doesn’t skimp on this crucial aspect. It’s powered by a fully discrete power supply that uses individually isolated discrete rails for filament, B+, and polarization voltages, ensuring stable operation with no calibration required. Sparkos Laboratories’ custom-made discrete regulator for the filament voltage provides clean, noise-free power, while the high voltage rails are regulated with discrete Zener diodes. The power supply also includes EMI/RFI filters to reduce unwanted interference, ensuring a smooth, transparent sound.

Premium Components for Superior Sound Quality
The UT Twin48’s exceptional sound is made possible by the use of high-quality, custom components. The microphone features a custom-made, dual-diaphragm, 24k gold-sputtered Mylar capsule, which captures every nuance of the sound source with an incredible level of detail. The capsule is optimized for 60V operation and finely tuned to match the exacting specifications of the original models, providing a smooth, natural sound with no harsh or sibilant overtones. The use of audiophile-grade capacitors, resistors, and other components ensures the UT Twin48 delivers a boutique-quality sound that rivals other high-end tube microphones.

Built to Last and Ready for Professional Use
Crafted with care in the USA, the UT Twin48 is built to withstand the demands of professional studios. The microphone features a solid, durable body made of high-quality materials, including a nickel-plated finish and brass housing. To ensure consistent performance in any studio environment, the microphone is equipped with premium components that are carefully tested for quality control. The microphone also includes a vintage-inspired briefcase that fits the microphone and its accessories, providing secure storage and easy transport for on-the-go engineers and producers. Whether you're using it for recording sessions or live performances, the UT Twin48 is built to last.
