Listen Technologies LT-84-01 ListenIR
2-Channel Transmitter and Radiator Combo; Provides venues, businesses,
government agencies, and more with an affordable and easy-to-use
assistive listening solution; Offering twice the IR power and up to
six times the coverage area of similar products, the LT-84
can transmit a clear, reliable signal across 2,787 square meters; UPC
LISTENTECHNLOGIESLT8401; This signal range ensures that users in any
mid-sized space, from boardroom to courtroom and beyond, enjoy
uninterrupted audio performance; The LT-84 is also the first infrared
assistive listening system to feature expansion radiators (LA-141),
which provide delay compensation to ensure that there are no signal
cancellation dropouts; Up to four (4) expansion radiators (LA-141) can
be added to the system to offer additional coverage; In addition, the
LT-84 is the only two-channel transmitter-radiator that can transmit on
up to four different frequencies (2.3 MHz, 2.8 MHz, 3.3 MHz, or 3.8
MHz); This flexibility in the field makes setup and operation even
easier, while also eliminating the need to purchase separate,
frequency-specific transmitter-radiator units; Thanks to a single CAT-5e
cable that provides power and signal, the included mounting hardware,
and the flexible frequency selection and input connectivity, the LT-84
is an ideal way to add infrared assistive listening capabilities and ADA
compliance to your business or venue; Dimensions 1.5" x 10.7" x 4.1";
Weight 0.8 lbs; Shipping Weight 3.4 lbs
