MODEL TR-2000 PROFESSIONAL
COMMUNICATIONS HEADSET

MODEL TR-2000 HEADSET

OPTIMIZED MICROPHONE RESPONSE

The Model 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 reproduction quality.

NOISE CANCELLING FEATURE

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 signal.

SPRING-LOADED FLEXIBLE BOOM

The Model 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.

LARGE, PLUSH EARPADS
AND HEADBAND

Although the 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.

COMPATIBILITY

The Model 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.

EASY, STEP-BY-STEP ASSEMBLY INSTRUCTIONS

The kit version of the Model TR-2000 is supplied with detailed step-by-step instructions, written clearly, avoiding electronic "jargon." These "check-off as you go" instructions enable even a person with minimal technical skills and experience to assemble the product successfully, in just a few hours.

CONNECTOR KITS & CONNECTOR
INSTALLATION SERVICE

For the convenience of our customers, we stock connector kits for many popular, late model radios.

Please check with us for availability of a connector kit for your radio. Call us toll free 1-800-634-0094.

For those individuals who prefer to purchase the headset with connectors already installed, we offer to completely install connectors on the Model TR-2000, for your "plug and play" installation on many popular, modern radios. The total price for a headset with connectors for your radio $58.95, or $68.95 for older radios. The list of radios which we support with connector installation service is constantly growing, so please check with us on our toll free number, concerning yours. 1-800-634-0094.
