1. Power On Procedure this gives you the ability to select the option that will apply when the DLM26 powers up after being switched on By pressing ENTER and rotating the Param 2 or Param 3 encoder it is possible to choose between two options Fade In On or Fade In Off The currently running option will be displayed with an asterisk to the right of the option description To change the option simply ENTER on the option not displaying the Asterisk and that option will become active and an Asterisk will now appear to the right of the option description The following two options are available FADE In Off when the DLM26 is turned on all Outputs regard of their status before the Unit was switched off will be MUTED or UNMUTED automatically meaning the DLM26 will have no active Outputs or active Outputs during the start up process depending from the Outputs previous status FADE In On when the DLM26 is turned on all Outputs not previously muted before the Unit was switched off will be active meaning the DLM26 outputs will be controlled by a volume ramp to avoid any sudden sound If the option Fade In On is selected the screen will show the following Delay Time Distance this page allows you to select the measurement unit to be used for the Delays Time in milliseconds ms or Distance in meters m By pressing ENTER and rotating the Param 2 or Param 3 encoder it is pos
