Microphone Input Transformers

This represents only a small fraction of what we manufacture. If you do not see it here, ask. We develop new ones all of the time to meet customers' requirements.     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. \ Part No.: Impedance Ratio: Operating Level: 1%THD+N Notes    CMMI-2C  (RE-16-A) 150 : 600 +8 dBu Mic transformer. p.c. and leads.
