AN-107: Authorized Replacement Transformers for the Langevin AM-16

Langevin AM-16 Microphone Preamplifier

The Langevin AM-16 remains one of the most respected microphone preamplifiers from the early days of solid-state professional audio. CineMag’s deep connection to its original design allows us to offer replacement transformers that meet the same exacting standards as the units that helped shape countless classic recordings.

A Classic Microphone Preamplifier with Enduring Studio Legacy

The Langevin AM16 is one of the acoustic gems from the early days of bipolar transistors being in professional grade audio equipment.  The AM16 were used by major studios such as Capitol Records to record numerous hits.

CineMag’s Authorized Role in Preserving the AM-16

CineMag is the sole authorized manufacturer of replacement Langevin transformers, courtesy of its relationship with Orphan Audio which  is the owner of all of the known existing Langevin transformer engineering documentation and is the owner of Langevin intellectual property.

We are proud that CineMag’s founder, Edward Reichenbach, as well as CineMag president David Geren, had personal and engineering relationships with John Hall who designed the AM16.   Their  relationships date back to the early 1970’s.  John approved CineMag’s reproduction of the AM16 transformers.
