Connecting the speaker array and power stand

The speaker array can be connected with or without the extension. Connecting without the extension might be useful, for example, when on an elevated stage to bring the array closer to ear level of the audience.
  1. Align the connector at the bottom of the extension with the connector on the power stand, then firmly press the extension into the power stand
  2. Align the connector at the bottom of the speaker array with the connector at the top of the extension, then firmly press the speaker into the extension.
    Tip: When properly connected, there should be no visible gaps where the pieces connect.

Powering on or off

Connect the power cord from the the POWER jack on the power stand to a working outlet. Then, on the back of the system, push the POWER button: When powered on, the light above the power button glows.
