Airports and other large transport hubs call for critical announcements delivered to a large audience from staff to passengers and most importantly, emergencies. In such a scenario where broadcast announcements are the norm, seamless functioning is an absolute must. The size of the venue and portability concerns are some factors that play a vital role.

A powerful sound is achieved through a system that has high signal-to-noise ratio (SNR). This ensures that every announcement, whether it is live, digitally stored, text-to-voice, or pre-recorded is at an adequate level above the ambient noise environment. Thus, the sound reaches loud and clear to every person concerned.
