If cabled connections are possible and the primary focus is on secure communication and constant availability for all participants, then there is no alternative to the CT-WireCom Digital system. The system permits continuous two-way conversation for up to 20 participants with superior speech transmission quality at levels of ambient noise approaching 110 dB (A). Since all headsets are equipped with CT-DNR (Digital Noise Reduction), all interference noise is digitally suppressed.

Thanks to the use of digital technology, volume levels no longer need to be adjusted when additional parties join the system – levels are adjusted fully automatically. Nonetheless, each participant can set his or her volume level individually on the headset.
