    The Tram TR50 is a professional omnidirectional electric condenser lavalier microphone with a low-profile design resulting in low visibility. The TR50 features a frequency response that enhances the character and frequencies associated with speech.

    The polar pattern provides a generous pick up response at the direct and off-axis sections of the microphone capsule. This enhances sensitivity and minimizes noise associated with movement, wind and clothing contact. The TR50 features minimum sound coloration and is available in a variety of connectors for direct integration with wireless transmitters. This version features a 1/8" (3.5mm) connection for use with Sennheiser EW wireless transmitters.

    Note: Please specify the model number of your wireless transmitter in the comments box shown in the shipping section of your shopping cart when placing your order.
