BEFORE YOU BEGIN
The MRX500 speakers covered by this manual are not intended for fixed installation in outdoor or high moisture
environments. Moisture can damage the speaker cone and surround and cause corrosion of electrical contacts
and metal parts. Avoid exposing the speakers to direct moisture. Keep speakers out of extended or intense direct
sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by long-term
exposure to intense ultra-violet (UV) light.
MRX500 speakers can generate considerable energy. When placed on a slippery surface such as polished wood
or linoleum, the speaker may move due to its acoustical energy output. Precautions should be taken to assure
that the speaker does not fall off a stage or table on which it is placed.
Stand mounting safety precautions
Some MRX500 models include a 35 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.

Route cables so that performers, production crew, and 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 MRX500 speaker on a stand or pole.

Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight (i.e. sand
bags) 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.
Hearing damage, prolonged exposure to excessive SPL
MRX500 loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause perma-
nent hearing damage to performers, production crew and audience members. Caution should be taken to avoid
prolonged exposure to SPL in excess of 90 dB.
