The Tram TR-50 is
a professional omni-directional, slightly peaked response lavalier microphone.
Its miniature size makes it ideal for field recording and studio or theater
applications. It may be had either hard wired for use without a wireless
microphone or it may be had wired with an appropriate connector for wireless
microphone use. When the cable is terminated with a connector appropriate for
wireless microphone use, the TR-79 power supply may be purchased with a mating
connector to allow the Tram to be used as a hard wired microphone as well. Tram
microphones are available for a variety of wireless microphone transmitter
makes and models. The more common ones are listed below. Should you not see
what you need below; Vark Audio can supply the Tram with almost any connector
for wireless transmitters. Tram microphone sets come with six accessories and the hardwired version comes with an additional cable reel. Note: The picture accompanying Tram TR-50
microphones and accessories is not necessarily the color indicated in the
picture. The color indicated in the drop down box is the color you will
be receiving.
