Microphone Output 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.

" >  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.  Part No.: Impedance Ratio: Operating Level: 1%THD+N Notes: Data Sheets       CMO-2.65/200CT 2650 : 200 CT (3.64 : 1) +14 dBu Condenser microphone output transformer.
