When it was introduced, the Tram TR-50 miniature microphone revolutionized the industry – it has become the standard in feature film, television production and other areas of the entertainment industry. In addition to its diminutive size and superior sound quality, the TR-50 offers a combination of features that are simply not offered by any other microphone. The TR-50 miniature professional lavalier microphone answers the needs of even the most demanding sound recording engineer. It has been designed with the latest electret development and electronics technology to provide high-sound quality with little or no visibility. Its small size and special design make it ideal for a variety of uses and fastening locations – particularly when situations require an unobtrusive appearance and hidden mic use.

The tiny omni-directional capsule features minimum sound coloration and is therefore easily combined with boom-mics during post production. A variety of accessories makes mounting the mic on or under clothing easy, with reliable results.

The extended frequency response range and omni-directional characteristics have been designed to satisfy the most stringent requirements in all professional audio fields, particularly film and TV production.

We find that most people need a TA5 connector for use with Lectrosonics wireless systems. However, the TR-50 is available with a variety of connectors for direct attachment to any wireless microphone transmitter. Please call for details.
