MODEL TR-2000 HEADSET
TR-2000 electret microphone's frequency response has been
tailored with a broad rise centering in the upper
mid-range and a smooth roll-off below 500Hz. This careful
"shaping" optimizes communications
effectiveness by increasing the clarity of the received
signal, while retaining a pleasing, natural voice
The Model TR-2000 uses
acoustic noise cancelling which was developed to allow
clear radio communications, in extremely high ambient
noise environments (such as cockpits of powerful piston
engine aircraft). Noise cancelling is accomplished by
allowing the rear of the microphone diaphragm, as well as
the front, to be exposed to the ambient noise field.
Since the front and rear sound waves differ in phase from
each other by 180 degrees, a highly effective
cancellation results. The ambient sound is substantially
prevented from being converted to an electrical analog,
thereby nearly eliminating it from the microphone output
TR-2000's flexible boom may be bent anywhere along its
length, in any direction. The "mechanical
memory" provided by the spring-loaded feature allows
the boom to maintain its adjustment, even when
accidentally bumped of pushed.
Model TR-2000 boom microphone headset weighs only 11
ounces, the large, plush, foam-filled earpads reduce
background noise substantially, allowing the operator to
hear received signals clearly, even in very noisy
environments. The matching padded headband increases
comfort on the top of the head and imparts a luxurious
appearance to the unit.
TR-2000 microphone and earphones are compatible with
almost all modern amateur radio equipment - fixed,
portable, handheld or mobile. It also should work well
with many "vintage" transceivers, receivers and
transmitters. The TR-2000PC version is compatible with
nearly any personal computer, and simply plugs-in to
sound card on the back of the PC, via the two
pre-installed 3.5mm phone plugs. Plug and play for
internet telephony or other voice applications.
