how to use this manual

format

This manual uses a format that is intended to be easy to read, yet technical for those who need to know all the details. For feature descriptions, this is done by devoting the left side of each page to 1) an overall module picture, 2) a block diagram, and 3) a con- trol closeup.These images all pertain to the features and control descriptions on the right side of the page.The intention is to make the manual easy to read while including all the technical details needed for getting the most out of the X-Rack - a compact, flexi- ble, feature-rich addition to Crest Audio's growing line of audio mixing console products.
