NOS Audio NOS251 Modeling Tube Microphone How do you emulate a classic microphone? You start with a classic microphone. The NOS251 starts off as a re-creation of one of the most sought after large diaphragm tube microphones of all time: the venerable ELA M 251E. Its sound is airy and present while at the same time full-bodied and smooth, characteristics that make it especially desirable for recording vocals or any instruments you want to sound larger than life. These characteristics also make it an excellent base for emulating other classic tube microphones, such as the C12, ELA M 251E, U47, U67, and C800G.
