Projects > Samar Audio Ribbon Microphone Transformers
Samar Audio’s RT line of toroidal transformers are specifically designed to get a perfect match with each particular ribbon microphone with impedance, damping, response curve, and noise. They can be used in DIY ribbon microphones, or for modification of existing commercial ribbon microphones. OEM is also possible. Each transformer is available with either a flat or bass-roll off frequency response. Try pairing it with the RE-154 ribbon motor.

One thought on “Samar Audio Ribbon Microphone Transformers”
I have read an article by the guy who started the Samar Audio recently (shame, I can’t find a link again) and it left a very good impression. Informative and thoughtful, clear ideas, no “audiophile mystics”. A person with such in-depth knowledge of the matter just can’t make his transformers bad. I haven’t tried them, but bet, they worth every penny.
