When it was introduced, the TRAM® TR50 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 TRAM® TR50 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 unique design permit a variety of uses and fastening options, that make it ideal for 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.
The TR50 is available with a variety of connectors (Micro-Mini, Lemo (4, 6 or 8pin), Mini Switchcraft (3, 4 or 5pin), Sony, Sennheiser, etc.) For direct attachment to any wireless microphone transmitter. In addition to its use with wireless transmitters, the TR-50 can be used as a low impedance hard-wired microphone with the TR-79 power supply. 12/48v phantom powering (in addition to internal powering) is available on all TR-50*PS microphones and TR-79+ positive bias power supplies.
The TR79 power supply provides a balanced transformer output to an XLR
connector and uses an Eveready 357 battery. The battery compartment is designed
to permit only one insertion direction, so the polarity cannot be reversed. This
compartment is accessible by turning the black plastic end cap counter clockwise
and pulling firmly. The battery is removed by pushing it out with a sharp object
through the hole provided in the bottom of the compartment.
When using the Clip On and Tape Down Holders under clothing, mount the mic with the back out (facing clothing), as the back of the microphone housing has less rubbing noise than the front grid. There will be no reduction in audio sensitivity. These accessories are available in Black, Gray, Tan or white.
Provides powering and balanced XLR output to the TR50 miniature microphone. Available in two powering configurations (microphone bias must match power supply bias.): TR79 Connection between the TR50 and TR79 is through a connector of choice (from an extensive list), matching the connector used by an accompanying wireless transmitter if required.

Positive Bias or Negative Bias? What's the Difference?
This is an extremely popular question.

There are are generally 3 types of repairs with TRAM® microphones:
Cable is intermittent (or frayed or pulled out) where it enters the mic head (mic element).
This
can not be fixed. Any problem with or near the mic head (mic
element) can not be repaired. The housing is assembled by a machine
at the factory and therefore is not serviceable. Your only solution
is to purchase a new mic. We offer the
mic only
with no case and no clips, and with or without a connector at a lower cost.
For mics that are hard wired into the power supply, we can
install a new mic head/cable assembly onto your old power supply (the approximate cost to replace a hardwired mic with a new head/cable
assembly is ~$238). To send us the mic for repair, please see the section
sending in a repair.
If you are still lost and have no idea whether it can be fixed or not or what component is at fault, you can send us everything and we can figure it out for you!
Manufacture Warranty
TRAM® microphones are warranted to the original purchaser to be
free from defects in material and workmanship under normal use for a period of
one year from date of purchase. During this one year period, and upon proof of
purchase, your
microphone will be repaired or replaced, at the
manufacture's option, without charge for
either parts or labor, provided the microphone is sent prepaid to the
manufacture. This
warranty will not apply if the microphone has been misused, abused, incorrectly
wired or altered. Warranty repair/replacement does not extend this warranty.
For warranty repairs, please contact the manufacture directly or contact the dealer you purchased it from.

distributor and therefore only handle warranty repairs on microphones that
we have sold.
