    These functions include crossover, equalization, delay, limiting, high-pass and low-pass filtering as well as signal distribu- tion. Programs may be created, selected and edited with the DS48's front panel controls. However, to create new programs, it is best to use the included free PC software and configure the programs using the graphical user interface (GUI) and a Windows PC.

    2. RS232 Interface Connect this to the serial port on a PC using the included cable or other standard DB-9 type cable. With the software installed, the PC can now monitor and program the DS48. 3. XLR Outputs 1-8 These are balanced (Pin 2 Hot) XLR outputs.
  • Page 10: Quickstart

    Before hooking up the system, make sure that all items are OFF, especially the power amps. Use high quality balanced XLR mic cables to make the connections. The feeds from the DS48 at "front of house" can also be sent through the audio snake returns to the amp stacks if used in a live setting.
  • Page 11 QUICK START Depending on the mode selected, other options will appear for this level of the menu, primarily concerned with input and output assignments. Some assignments are fixed with the crossover type selected. Only those assignments that can be selected will show on the display. Either the BACK/NEXT (2) buttons or the Parameter dial will work for stepping through the selections.
