Frequency Band IV

Interference generated through switched lighting systems or energy saving lamps (especially the harmonic waves of these devices) sometimes cause infrared receiving problems in Band II. These harmonic waves can disturb more than half of the Band II. In order to avoid these interference problems the usable channels may be shifted up or must work in Band IV.

How the system works

As the speaker delivers the speech, interpreters translate it simultaneously into the corresponding language. This is also possible the other way around: the simultaneous interpreter will translate any question from the audience into the preferred language of the speaker. Each conference delegate hears his language of choice via headphone. The infrared receiver can be set to the required language and volume.

Brähler ICS units support up to 32 languages in Band II and in Band IV. Therefore, they are suitable both: for small and large scale conferences. The INFRACOM system consists of the compact transmitter MSI8D (8 channels), interpreter console DOL7/2 (1+ 6 channels), high-power radiator IRad and conference receiver IRX (2, 12 or 32 channels). The system is fed by an audio signal from conference systems like AUTOMIC, CDS200, DIGIMIC, CDSVAN or other audio sources.
