Univox TLS-2.2 - Introduction
Univox TLS-2.2 is an audio induction loop driver developed for hearing loop installations
in railway and other large vehicle applications. With its rugged and sophisticated design
TLS-2.2 ensures efficient and reliable operations in environments completely or partially
enclosed by metal, like train cars, trams, subways and ships.
TLS-2.2 provides high output current, up to 30 Arms, enabling compensation for the strong
damping effect that conductive materials may have on magnetic transmission. Metal loss
correction is also available for high frequency slope corrections.
