WIR TX90 DC

Large-area multi-channel infrared transmitter

The WIR TX90 DC two channel IR transmitter combines modulator and emitter technology into a single operating unit, which reduces
operating cost and eliminates precious rack space. The WIR TX90 DC transmitter produces a wide-angle infrared signal that

concentrates the IR energy eciently in the listening area. By modulating with frequencies 2.3-3.8 MHz bandwidth, the WIR TX90
DC is less susceptible to radio and lighting interference. Each WIR TX90 DC transmitter can cover up to 30,000 sq ft (2,787 sq m) in

single-channel operation. The coverage area can be easily increased by connecting additional WIR TX9 DC emitters. A wall/ceiling
mounting bracket is included, and stand kits are available for portable operation.
