Tram Lavalier Microphones

     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.
