• Annotazioni
• The T-32 was manufactured for the US Army Signal Corps by Kellogg. The microphone is a single button carbon element that requires a small bias voltage. The bias voltage is supplied by the transmitter or other equipment that the T-32 was used with. Audio reproduction is communications quality. The element can be readily replaced, if necessary. The push-to-talk switch can be used to actuate the equipment that the microphone is to be used with. The T-32 dates from the late twenties and was mainly used for military communications up to WWII and sometimes even beyond into the early fifties. A popular microphone with the Signal Corps.
