- What is the difference between a Neumann M49 and M249? or KM54 and KM254?

The "200" series of Mics was built to the specification of German Broadcast. The ONLY difference is the larger RF shielded connector. Everything else is identical. We see KM254, 253, 256, M269 (AC 701 version of the U67), M249, M250, etc.

-What is the warm up time for a VF14 tube?

The Neumann recommended warm up time for a VF14 tube is ONLY 1 minute!
