Tram TR-50 Lavalier Microphone with Vega Lemo 4-Pin Positive Bias Black
When it was introduced, the Tram TR-50 miniature microphone revolutionized the industry - it has become the standard in feature film, televison 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 therfore 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.
The TR50 features minimum sound coloration and is available in a variety of connectors for direct integration with wireless transmitters. The TR79 power supply (not included - for power supply order XL models) allows direct connection to XLR microphone inputs.
Bias is basically which way power flows to the microphone. Think of any piece of electronic equipment that requires a battery to work. When you install the battery, you need to insert it the correct way. The positive(+) side and the negative(-) side of the battery needs to be inserted the proper way. If you insert the battery the wrong way it won't work.
If you are using a wireless microphone system or a lavalier power supply, that unit's bias and the bias of the lavalier must match for the microphone to work. Some wireless system only offer negative bias, some only offer positive bias and some offer both bias options. The same goes for lavalier microphones, some can only be used with negative bias, some only with positive bias and some can be wired to be used either way. The ones that offer both options are of course the most versatile, but also the most confusing. Lectrosonics Wireless Systems and Tram Microphones are two examples that offer both bias options. So whether your Tram is wired for positive or negative bias, it will work either way with a Lectrosonics. The problem comes into play when you are using a "detachable lavalier power supply". If the power supply is positive bias, the microphone must be positive bias as well. If you attempt to connect a negative bias microphone into a positive bias power supply, it will not work.
