Description
Microphone Input Transformer VTX-MIC11
1 CT : 0.5+0.5 150Ω 8dBu
Microphone Input Transformer VTXMIC11 – designed specifically for impedance matching with the pre-amplifier stage
- for mic pre-amp input circuits to match microphones to pre-amp
- in tube microphones for matching high impedance tube circuits to normal output impedance
- in ribbon microphones to transform very low voltage, very low impedance ribbon motors to normal microphone output levels
