The gray Tram TR50 is a miniature omnidirectional lavalier microphone designed to deliver clear speech and dialog with a natural sound that mixes well with boom microphones, making it popular among professional sound recordists working in TV, film, broadcast, videography, and more.
The mic s omnidirectional polar pattern provides a generous 360° pickup response that helps to keep levels consistent, even if the talent turns and isn t speaking directly in the direction of the capsule. The flat, upward facing design allows the mic to be easily concealed while also helping it to resist clothing and rustling noises.
The TR50 features a 40 Hz to 16 kHz frequency response with a gentle 3 to 4 dB boost in the high frequencies for added clarity with minimum sound coloration, especially helpful if the mic is hidden behind clothing or fabric. This version of the TR50 is hardwired with a positive bias, a built-in TR79+ power supply, and an XLR connectora making it well suited for a wide variety of wired applications.
The mic is powered by 12 to 48V phantom power or the button-cell battery in the power supply. A tie bar, tie tac, clip-on holder, and tape-down holder are provided to help you mic up your subject. A windscreen, cable holder, cable reel, and carrying case are also included.

Miniature Mic Plays Well with Other Mics
The TR50 offers a small, flat design that offers flexible positioning options while isolating the mic capsule to help resist rustling and clothing noisea especially helpful for hidden or concealed uses. The mic s clear, uncolored reproduction of speech and dialog mixes well with boom mics in post production.
Headroom for Robust Speakers and Performers
With its ability to handle SPLs up to 134 dB, the mic offers plenty of headroom for most speech and vocal applications.
Omnidirectional Polar Pattern
The forgiving omnidirectional polar pattern picks up sound from all around the mic and provides a consistent frequency response, even for off-axis sound. This helps to supply clear, intelligible speech and vocals, even when the talent isn t speaking directly toward the microphone.
Positive Bias
This version of the TR50 is wired with a positive bias and a TR79+ power supply, allowing the mic to be powered via 48V phantom power or the LR44 battery in the power supply for wired use with XLR equipment. Negative-bias versions of the TR50 do not support phantom power and can only operate on the battery-powered TR79. When recording with multiple TR50 lavs, always use models with the same bias to avoid phase-cancellation problems.
