The 6 (5 + off) position selector CT 61 shall be matched to a (not included) RCF TL 128 line transformer (or equivalent), in order to get a volume control for a loudspeaker group (in a 100 V constant voltage system) having a total power not exceeding 120 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 selector or insert a second 100 V line (not affected by the volume control) for paging. It can works with 3 wire lines as well, in order to make emergency announcements without using the internal 24 V dc relay. CT 61 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
