IR Audio Transmission Technology |
General Description
The SI 29-5 is a 5-channel modulator. Its audio channels can be programmed to any
of the 32 narrow-band channels, and monitoring is no problem due to integrated IR
transmission diodes. The modulator is easy to program and features clear LED dis-
plays for monitoring all modulator functions.
