CM48 T $595.00 USD

CM48 T CM48 T

Advanced Audio CM48T

Our 3-pattern tube microphone based on the vintage U47 that in 1958 added a 3-pattern version called the U48 with OMNI, CARDIOD and FIG 8.

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 put up on electric guitar or bass cabinet, on kick drum and other high SPL sources, yielding great results.

Stay tuned for clips!

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!

If your looking for that vintage tube mic sound, in a smaller, amazingly affordable package, the Advanced Audio CM48T is that microphone at $595USD!


 Like the original circuit designs, we are using a pentode tube wired as a triode, but the use of modern, high tolerance components results in a far quieter, more reliable microphone.

The single class "A" tube circuit stage uses a GE/JAN 5654W sub-miniture 7 pin tube,


Our custom wound BV18 transformer, with bi-metal laminations, and 8:1 ratio on the output yields outstanding headroom.


We use our tried and true, AK47 capsule, the same used in our CM47ve, CM49 and CM47fetCE microphones. All Advanced Audio Microphones capsules are hand skinned using 6 micron, gold sputtered mylar. Each capsule goes through rigurous testing here in our shop in Canada.
