The SigNET PRO Range comprises of constant current, single and dual induction hearing loop
amplifiers, each with a graphical display. The dual loop amplifiers have a built-in phase shifter,
designed for ‘phased array’ induction loop systems. They may be free-standing, or wall-
mounted and are designed to cover areas up to 200m
