  • Page 16: Chapter 2: Installation

    CHAPTER 2: Installation The XAP 400 is designed for easy installation and setup. All connections are made through rear-panel connectors. This chapter provides instructions on installing the units and making initial connections, creating an expansion bus (E-bus) network, assigning device ID numbers, selecting the mixer mode, and using the LCD menu.

  • Page 17: To Connect The Unit

    Plug in the XAP 400 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 400 and are not connecting it to any other XAP or PSR1212 units, you have completed the hardware installation.

The XAP 400’s CD Horn EQ compensates for this characteristic. Crossover A device that passes designated frequency segments of an audio signal to various loudspeaker elements in a sound system.
  • Page 159 E-bus network. Because up to eight XAP 400s may be used in the same network, the device ID range is 0–7. Device Type A number which identifies the type of unit. For example, a XAP 400 is device type 7.

  • Page 163 Off Attenuation The amount of level reduction a microphone is given when the microphone is not gated on. PA Adaptive Mode The XAP 400 recognizes how much loudspeaker audio is picked up by the microphones and then uses this level as the new ambient level when audio is present at the power amplifier.
