Common name: Advanced Audio CM48T

Production Status: In production

This 3-pattern tube microphone is based on a combination of the vintage U47 and U48 microphone made after 1958.  The CM48T has a traditional single stage class “A” U47/U48 type circuit. Advanced Audio added a 3-pattern option combining the OMNI feature of the U47 with the FIG-8 feature of the U48 while retaining the passive, polarisation method of the original U47 and U48 microphones. The CM48T an exceptional microphone with an amazing attention to detail built into a very compact body with extremely high quality components.In studio testing, we have found it to be an excellent choice for vocals, over the drums, or on acoustic guitar. The CM48T can easily be placed on electric guitar amplifiers, on a bass cabinet, on kick drum and other high SPL sources, yielding great results.  Its small stature and added -10db pad allows it to perform recording tasks once thought to be impossible from larger vintage tube microphone circuitry.It is a perfect addition to any project studio as your first tube mic. It has been designed to work seamlessly in any serious commercial studio as well. You can buy a matched pair without breaking the bank and with the FIG-8 option use them as a Blumlein pair. Like the original circuit designs, we are using a socketed 7-pin military grade pentode tube wired as a triode.  The use of modern, high tolerance components results in a far quieter, more reliable microphone with the extra feature of 3-patterns and a -10db pad. The single class “A” tube circuit stage uses a military GE/JAN 5654W sub-miniature 7 pin tube.  Great care was take to closely match the plate current and output impedance parameters to that of the original VF14 tube found in vintage U47 & U48 microphones. The CM48T uses our tried and true, AK47 capsule, the same capsule used in our CM47ve, CM49, CM48fet and CM47fet/CE microphones. All Advanced Audio Microphones capsules are hand skinned using 6 micron, gold sputtered mylar. Each capsule goes through rigorous testing procedure.
