TR50 Lavalier Microphone
When it was introduced, the TRAM
®
TR50 miniature microphone revolutionized the
industry- it has become the standard in eature ilm, television production and other areas o
the entertainment industry. In addition to its diminutive size and superior sound quality, the
TR-50 o ers a combination o eatures that are simply not o ered by any other microphone.
The TRAM
®
TR50 miniature pro essional lavalier microphone answers the needs o 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 o uses and astening options, that
make it ideal or unobtrusive appearance and hidden mic use. The tiny omni-directional
capsule eatures minimum sound coloration and is there ore easily combined with boom mics
during post production. A variety o accessories makes mounting the mic on or under clothing
easy, with reliable results.
The extended requency response range and omni-directional characteristics have been
designed to satis y the most stringent requirements in all pro essional audio ields, particularly
ilm and TV production.
The TR50 is available with a variety o connectors (Micro-Mini, Lemo (4, 6 or 8pin), Mini
Switchcra t (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 trans ormer 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 irmly. The battery is removed
by pushing it out with a sharp object through the hole provided in the bottom o the
compartment.

Repairs
There are are generally 3 types o repairs with TRAM
®
microphones:
•
Connector
o
Cable is intermittent at the
connector end o the mic (or
where the cable enters the
power supply on a hard-wired
mic). This is by ar the most
common problem. The solution
is to cut the cable back about 1
inch rom the connector and re-
install connector. We provide
this service or $41 plus
shipping with a turn-a-round o
a couple o days ($50 plus
shipping or hard-wired mics to rebutt the cable where it enters the power
supply). We can also replace the connector i it is damaged at that time-
connector costs vary rom connector to connector. To send us the mic or
repair, please complete our Repair Form.
•
Head
o
Cable is intermittent (or rayed 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
actory and there ore is not serviceable. Your only solution is to purchase a
new mic. We o er 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 ~$225 and you can send it to us using our Repair Form).
•
Power Supply
o
Power Supply is dead. First make sure you test the power supply with another
known "good" mic. Second, make sure the bias o the microphone is the same
as the power supply (See FAQs above about Bias). Third, make sure you are
using a "good" battery. It is very rare that we see a bad power supply and
the cause o the ault is generally one o the items just listed. I you have tried
all three o those things and the power supply still doesn't work, then your only
recourse is to purchase a new power supply as it is a non-serviceable item.
o
Cable is intermittent or rayed where it enters the power supply on a hard-
wired mic. This is repairable, see "Connector" type repairs above.
I you are still lost and have no idea whether it can be ixed or not or what component is at
ault, you can send us everything and we can igure it out or you!
