DuraFlex™ Finish
The DuraFlex finish used on your MRX500 series speakers is one of the most rugged finishes ever applied to a
speaker. However, all speaker finishes are subject to damage. Should the DuraFlex finish require repair, a touch-
up kit (Part Number 16677) is available from JBL Professional Parts.
Single Box On Pole Coverage
The dual angle pole socket on the MRX512M and MRX515 provides flexibility in aiming the speaker. As a gen-
eral rule, the speaker should be positioned so that the audience cannot see the top or bottom panels of the
speaker. 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.
• Be certain that the surface on which the system is to be stackedis flat, stable and solid.
• Route cables so that performers, production crew and audience will not trip and topple the speakers.
• Inspect the stand (or pole and assorted hardware) before each use and do not use equipment with
worn, damaged or missing parts.
• Always be cautious when deploying the system outdoors. Unexpected winds may topple a system. It
may be necessary to place additional weight (i.e. sandbags) on the base of the stand to improve
stability. Avoid attaching banners or similar items to any part of the 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 stand or pole.
