The TT-1020 is designed to provide consistent intelligible emergency notification for enclosed linear spaces and other long projection applications. Precise pattern control and very narrow coverage angles deliver outstanding performance in highly reverberant environments.
To meet the performance goals for long projection emergency notification, the system utilizes a single high power purpose-built MF transducer, ensuring accurate signal reproduction and very low distortion. Biamp's proprietary 2-inch (51 mm) exit compression driver delivers high intelligibility at elevated sound pressure levels necessary to overcome the high ambient noise and reflected acoustic conditions. This makes it ideal for road or rolling stock tunnels and similar acoustically challenging environments. The large-format waveguide ensures precision directivity control throughout the entire voice band.
