Description
The United Studio Technologies UT Twin48 is an exceptional preservation of two venerable classic tube microphone designs. The original classics of the late ‘40s and ‘50s have been front and center in countless recordings, United has taken these classic-specification designs to the next level by uniting both designs into a single microphone.
The classic 47 and 48-style mics each derived their cardioid operation in very different ways — producing subtle tone differences as well as a slightly different polar pattern. For the first time ever, the UT Twin48 delivers both options in a single microphone.
Massive tube sound calls for the right tube: The UT Twin48’s amplifier stage is based around a select new old stock EF86 pentode glass vacuum tube — the last living descendent of the originals’ tube. This results in a bold, rich sound, due to the pentode’s harmonic profile being much different than modern dual-triode tubes.
United Studio Technologies UT Twin48 Features:
- Tube Microphone
- 2 microphones in one based on the original Neumann U47 and U48
- 47 Mode offers both 47 Cardioid and Omni patterns, while 48 Mode offers 48 Cardioid and Figure-of-8:
- 47 Cardioid: de-couples the rear diaphragm in a process known as True Cardioid, for a louder sound with improved sensitivity with more background and top-end detail.
- 48 Cardioid: polarizes the rear diaphragm with the same voltage as the backplate — AKA Active Cardioid — for a more tightly closed-in, warmer, intimate tone that is a bit lower in sensitivity.
