  • Page 15: Chapter 2: Inst Allation

    CHAPTER 2: Inst allation The XAP 800 is designed for easy installation and setup. All connections are made through rear-panel connectors.This chapter provides instructions on making hardware connections, creating an expansion bus (E-bus) network, assigning device ID numbers, selecting the mixer mode, and using the front panel LCD menu.

  • Page 16: To Connect The Unit

    Plug in the XAP 800 to complete the installation. The power output [A] will operate at any level between 100–240VAC and 50–60Hz. If you are installing only one XAP 800 and are not connecting it to any other XAP or PSR1212 units, you have completed the hardware installation.

    XAP 800 or XAP 400. For example, if the cable from the XAP 800 to the XAP TH2 is 50 feet and the cable from the XAP TH2 to the second XAP 800 is 50 feet, then the total length between the two XAP 800s is 100 feet which is beyond the maximum 80-foot limit.

  • Page 18: Device Ids

    Once your expansion bus connections are made (and if you have more than one XAP 800 at a site), you need to set up a unique expansion bus device ID number—a network address—for each XAP 800 on the network. As shipped from the factory, all XAP 800s are set to device ID 0.
