The Z-LT-84 is a 2 channel Infrared transmitter and radiator that is easy to use and install
The Z-LT-84 is a 2 channel Infrared transmitter and radiator that is easy to use and install whilst also being a cost effective system that can provide a large area coverage. One CAT-5e cable provides both the power and the audio signal to the transmitter and to the Z-LA-141 expansion radiator.
Combined with Z-LR-4200 and Z-LR-5200 infra red receivers the Z-LT-84 can provide up to 30,000 ft² of coverage without gaps or null spaces. So to provide maximum flexibility in the field the two channel system can use up to four frequencies.
Available with a multitude of mounting and accessories options this infrared assistive listening system can provide for an array of applications.
Affordable, effective, and expandable solution ideal for small to mid-size spaces such as classrooms, courtrooms, boardrooms, and more
Multiple frequency options offer additional flexibility and simplicity during installation and setup
Offers gapless coverage up to 2,787 square meters (30,000 square feet)
Can be expanded with up to four (4) LA-141 expansion radiators for additional coverage area
One-cable design utilizes a single CAT-5e to carry both power and signal to LA-141 expansion radiators
Multiple input options for easier setup and operation
