The Current Thinking ET120 is an Induction Loop Amplifier (AFILS), which covers areas of up to 64m² or 120m² respectively. (These coverage areas are greatly increased if the area to be covered is rectangular – up to 165m² and 350m² respectively.)

This particular model is useful for Induction Loop installations in buildings which feature metal reinforcement or structures in the ceilings and floors. If part of a 100V Line distributed Sound System, the ET60/ET120 can be installed parallel with the loudspeakers.

Front mounted LEDs indicate input signal limit and peak loop drive current status.
