AT 40T volume control is made of a control circuit having a 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 40 W. All connected loudspeakers shall have 100 V line matching transformers. It includes a 24 V dc override relay to either bypass the 6 position (5 + off) selector or insert a second 100 V line (not affected by the volume control) for paging. It can operate with 3 wire lines as well (in order to make emergency announcements without using the internal 24 V dc relay). It can be installed on whichever supporting frame for home / office electrical systems by drilling a hole in a blank key and fixing the control circuit. 3 knobs are included in 3 different colours: white, silver, anthracite. If there is enough room, the transformer can be put inside the wall / flush mounted box (where the control circuit is).
