ET30 Induction Loop Amplifier

The ET30 is designed for user-friendly installation to walls, vanity panels, desks and counters. The unit is compact, the front is printed with text boxes to allow the name of the responsible person and their contact number to be written in. The controls (Mix and Drive) are recessed to hinder unauthorised adjustment, and LED indication is provided for the presence of power and loop current.

The unit incorporates the latest design in audio processing allowing varying microphone levels to be compensated for automatically while preventing any sudden loud noises from reaching the output stage. The compressor design automatically adjusts the release time providing high quality music with a slow release and speech with a relatively fast release.

The compressor ratio is dynamically variable and will automatically change from 1:1 to over 20:1 in the case of limiting. The unit also provides an automatic noise suppression system, reducing the level of audible hiss from the compressor as gain is added to the system.
