AT20T garso reguliatorius 20W/100 V (be rėmelio)

Attenuator for constant voltage systems, max 20W
Universal mounting on any standard European electrical wall plate.

AT 20T volume control is made of a control circuit having a 6 position (5 + off) selector and a separated transformer. It can be used in 100 V line systems to adjust the volume level of a loudspeaker group having a total power not exceeding 20 W. All connected loudspeakers shall have 100 V line matching transformers.
It can be set (through an internal jumper) to operate with 3 wire lines (in order to make emergency announcements at the max. volume). AT 20T can be installed on whichever supporting frame for home / office electrical systems by drilling a hole in a blank key and fixing its control circuit. 3 knobs are included in 3 different colours: white, silver, anthracite. The transformer can be put inside the wall / flush-mounted box (where the control circuit is).
