Transformerless Line Level Mics

The modification and updating of a good mic, the Classic AKG 414 P48, that turn it into a great mic!

In this article we detail the modification of a classic mic the AKG 414 P48 build during the mid 1980's. We undertook to turn this microphone into a line-level, transformer-less mic that has outstanding performance and has been used in many commercially released recordings ever since.

We will also detail a re-design of the line-level preamps that bring the performance to new levels, and adds some exciting new technology as well.
