output to a 100 V-line or 70 V-line loudspeaker system. They are not intended for any other
purpose.

CXL Series transformers can be found in the Installation Guide supplied with the Cloud rack trays
Models CXL-800 and CXL-1600. If you intend to install this transformer without a Cloud rack
tray, and do not have experience in wiring high voltage transformers, we strongly recommend that
you download the full manual from www.cloud.co.uk, and follow the guidance therein.
