NEAR FIELD TRANSMISSION
for installed and mobile multilingual conference setups, tour guides and assistive listening

The CSX IRT3 and CSX IRT4 are 10 channel infrared transmitter. Using digital PPM signal always all LED's cover the same area and distance, regardless the number of channels needed in an application ensuring perfect coverage even with changing channel needs. The CSX IRT3 and 4 can be cascaded almost without limit due to a signal refresher built into all transmitters. Even very large areas can be covered. The transmitters are designed in a way that no cooling fans are needed -- they act absolute quiet without any noise. Clearly visible LED's indicate the status from the distance, providing highest security for the technician on site.

The CSX IRT4 is designed for near field use, e.g. in ceilings above the area to be covered. The radiation angle is +/-60° and the working distance up to 35m.
