| CineMag manufactures an extensive line of Microphone Output
transformers. We only list a portion of our full product line.
We make transformers for ribbon microphones, vacuum tube output
stage condenser microphones, and solid state microphones of all
types. Dual bobbin construction is normally used for the best
possible CMRR which also permits phantom powering of the
microphone. Proprietary laminations and mixes of exotic
materials (high nickel and cobalt) can be found in these
meticulously crafted Mic Output transformers. |
