Current Thinking ET120 Loop Amplifier
The Current Thinking ET60 and ET120 wall mounted induction loop amplifiers (AFILS) cover 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 model is useful for induction loop installations in buildings which feature metal reinforcement or structures in the ceilings and floors as it features a metal loss correction system.

If part of a 100 volt line distributed sound system, the ET60 / ET120 can be installed in parallel with the loudspeakers.

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