Microphone Bridging Transformer, Quad Faraday Shields for High Isolation
Model: JT-MB-E
- Provides 3 additional, isolated balanced outputs as mic splitter
- Stops ground loop problems when a mic feeds multiple preamps
- High common-mode rejection 120dB at 60Hz
- Excellent frequency response and time domain performance
- Low insertion loss 2.2dB typical

Microphone bridging transformer is designed to be driven from a 150ohms microphone source and for each secondary to be loaded by the 1kohms input impedance typical of microphone preamps. The use of individual Faraday shields on each winding produces excellent RF attenuation. A 30dB magnetic shield package is standard.
