Microphone Transformers are necessary for good coupling of the microphone to the pre-amplifier stage. CineMag's experience goes back to the 1940s with Ed Reichenbach's pioneering designs for Altec-Lansing. The technology has made huge strides since then, but the reasons for employing CineMag's superior quality mic transformers remain the same: Excellent impedance matching between the microphone and the pre-amplifier, excellent balance and common mode rejection ratios (CMRR), very low distortion, and superior bandwidth. |
