Stand Mounting Safety Precautions Always follow instructions and precautionary advice from the speaker stand manufacturer.
This speaker contains a 36 mm receptacle cup to allow mounting on tripod stands or on a pole over subwoofers. When using stands or poles, be sure to observe the following precautions:

  • Check the stand or pole specification to be certain the device is designed to support the weight of the speaker. Observe all safety precautions specified by the manufacturer.
  • Always verify that the stand (or subwoofer/pole) is placed on a flat, level, and stable surface, and be sure to fully extend the legs of tripod-type stands. Position the stand so that the legs do not present a trip hazard.
  • Use this floor stand only on a flat, solid surface. Once the support (extended leg) has been placed and adjusted, carefully tighten the screws and use the safety pin. After placing the speaker on the stand, check for stability: When tilting each direction to 10 degrees (for the surface), the speaker should not turn off. If necessary, reduce the height of the speakers and extend the base of the stand.
  • Route cables so that performers, the production crew, and the audience will not trip and topple the speakers over. Inspect the stand (or pole and associated hardware) before each use and do not use equipment with worn damaged or missing parts.
  • Do not attempt to place more than one PartyBox series speaker on a stand or pole.
  • Always be cautious in windy, outdoor conditions. It may be necessary to place an additional weight (i.e. sandbags) on the base of the stand to improve stability. Avoid attaching banners or similar items to any part of a speaker system. Such attachments could act as a sail and topple the system.
  • Unless you are confident that you can handle the weight of the speaker, ask another person to help you get it onto the tripod stand or pole.
