Description
Microphone Bridging Transformer VTX-MICB1
Microphone Bridging Transformer VTXMICB1 – Used in audio applications to connect a microphone to an audio input without heavily loading the microphone’s output. It’s designed to “bridge” the connection by presenting a high impedance to the microphone while driving the input stage of the connected device effectively. 1:1 150W 0dBu
- Provides isolated balanced output
- Low insertion loss
- Can be used in reverse for 1C.T. : 1
- Fitted with multiple electrostatic screens
- Low distortion Mu-metal core
- Mu-metal screening can reduces electrical noise by up to 30dB
- Hi-pot, primary to secondary: 500VDC
- Windings to screens+can: 500VDC
- Operating temperature range: 0 to +70 C
- Storage temperature range: -25 C to +120 C
- Mass = 0.058kg
