Description
Microphone Bridging Transformer VTXMICB2
Microphone Bridging Transformer VTXMICB2 – 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. 1:1:1 150Ohm 2dBu
