A 1:1 sounding replica of the beloved Telefunken M49

The Stam Audio SA-49 is an exact sounding replica of one of the most sought after tube microphones in history, the Telefunken M49. With some clever adjustments and the aid of a NOS 6SB6-V tubes, a custom made K49 capsule and a US-made AMI BV11R output transformer we have managed to give this replica the true character of an original M49 at a fraction of the price, making it affordable to everyone. The SA-49 has a dual-diaphragm design with a remotely switchable pickup pattern having constant sensitivity: the psu doubles as a pattern selector, with a continuously-variable potentiometer for choosing cardioid, omni-directional, figure-eight or any position in-between the three.

The SA-49 is made with premium components

Since the capsule is the single most important component on a microphone’s tone, we have decided to take extra care and use the best replica available of both the K49 on the market. Each capsule is individually tested on both sides to match an original K47/M7 frequency response.

The SA-49 features premium capacitors on the audio path as well as polystyrene capacitors, which are more stable and much more linear in the top end which makes them the perfect choice for feedback circuitry. Additionally, the unit features a NOS 6SB6-V tube reducing noise and the output impedance to give this microphone the true character of an original M49 microphone.

Critical to the microphones timbre is the output transformer which is as important as the capsule on this circuit. After testing dozens of samples and every BV11R replica under the sun we settled for the US made AMI BV11R which is wound to original Braunbuch specification using custom UI30 laminations.

We have remained 100% faithful to the original vintage circuit and schematic and have made no compromise in parts, which ensures you get the best possible sounding microphone.

Each SA-49 comes with a rock solid power supply with a voltage selector which allows you to use it anywhere in the world and includes a premium XLR cable with a locking system. Directional patterns can be switched on the microphone head basket.
