Description:
The TX90 two channel IR transmitter combines modulator and emitter technology into a single operating unit, which
reduces operating cost and eliminates precious rack space. The TX90 transmitter produces a wide-angle infrared sig-
nal that concentrates the IR energy efficiently in the listening area. Operating on the 2.3-3.8 MHz bandwidth, the
TX90 is less susceptible to radio and lighting interference. Each TX90 transmitter can cover up to 28,000 sq ft (2,600
sq m) in single-channel operation. The coverage area can be easily increased by connecting additional TX9 emitters.
A wall/ceiling omnidirectional mount is included, and stand kits are available for portable operation.
Applications:
Cinemas • Simultaneous Interpretation • Audio Description • Conferences • Multi-Media Rooms
Boardrooms • Courtrooms • Schools • Universities • Churches
