JBL JRX118SP manual Before You Begin, Amplifier Module Precautions

BEFORE YOU BEGIN

JBL Professional does not support suspension of the JRX100 models covered by this manual nor are these models intended for fixed installation in outdoor or high moisture environments. Moisture can damage the speaker cone and surround and cause corrosion of electrical contacts. 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.

JRX100 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.

Some JRX100 speaker models include a 35mm receptacle cup to allow mounting on tripod stands or use of a pole to mount a satellite speaker over a subwoofer. When using stands or poles, be sure to observe the following precautions:

·Check the stand or pole specification to be certain it is designed to support the weight of the speaker.

·Observe all safety precautions specified by the stand manufacturer.

·Always verify that the stand or subwoofer 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 over them and pull the speaker over.

·Do not attempt to place more than one speaker on a stand designed for a single speaker.

·Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight (i.e. sandbags) on the base of the stand to add stability.

·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

JRX100 loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause per- manent hearing damage to performers, production crew and audience members. Caution should be taken to avoid prolonged exposure to SPL in excess of 90 dB.

Amplifier Module Precautions

Do not attempt to service this unit beyond instructions contained in this manual. Refer all servicing to a JBL Professional Authorized Service Center. Serving is required when the apparatus has been damaged in any way, such as power-supply input connector is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

Keep your JRX118SP amplifier module away from sources of heat, such as a radiator or oven. Do not cover or surround your JRX118SP amplifier module with material that may retain heat, such as a blanket or cur- tain. Be certain that the vents on the panel of the amplifier module are clear of all obstructions during opera- tion.

WARNING - Shock Hazard: To reduce risk of fire or electric shock, do not expose this unit to rain or mois- ture. Do not immerse your JRX118SP amplifier module in any liquid. Do not operate your JRX118SP near a pool, bathtub or other standing water. Do not bypass or defeat the grounding or polarization means used on the JRX118SP amplifier module. Make sure all blades on the polarized power plug can be fully inserted into the receptacle or other outlet that will be used with the unit. Your JRX118SP amplifier module should be cleaned only with a dry cloth. Take care of the power cord attached to your JRX118SP amplifier module. Avoid situations where your cord might be stretched, pinched, or otherwise abused. Route it to avoid foot traffic. Pay special attention to the cord connector and attachment points.
