The Vortexion 400 Series of mixer and induction loop amplifiers has been designed to complement the established Vortexion 4000 Series. Manufactured in Great Britain, the new range maintains the Company's traditional high standards of construction, sound quality and reliability.

Induction loops are increasingly used for the assistance of the hard of hearing, the relaying of commentaries and translations and for increased intelligibility of speech generally, wherever the symbol is displayed - in public places, at conferences, in theatres, museums, banks, post offices and railways. The 400 Series induction loop amplifier, with a loop drive of six amps rms, offers the user a choice of up to six input channels and is designed to cover an area over 500 square metres.
