NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous” voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in this manual. 1- Read these instructions. 2- Keep these instructions. 3- Heed all warnings. 4- Follow all instructions. 5- WARNING: To prevent fire or electric shock, do not expose this equipment to rain or moisture. Do not use this apparatus near water. 6- Clean only with a dry cloth. 7- Allow a minimum of 6” (152mm) clearance at cabinet back for convection cooling. Keep anything that might restrict airflow away from the rear of the enclosure (i.e draperies, fabric, etc...). Do not block any ventilation openings. This product contains an internal power amplifier that produces heat. 8- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9- Do not defeat the safety purpose of the grounding-type plug. The grounding plug has two blades and a grounding prong. The third prong is provided for your safety. If the provided plug does not fit your outlet, consult an electrician for the replacement of the obsolete outlet. Do not cut off the grounding prong or use an adapter that breaks the grounding circuit. This apparatus must be properly grounded for your safety. 10- Protect the power cord from being walked on or pinched, particularly plugs, convenience receptacles, and the point where they exit from the apparatus. 11- This product is not equipped with an all-pole mains switch. To fully disconnect from the AC mains, the AC plug must be removed from the AC outlet or the appliance coupler (IEC block) must be removed from the amplifier module. Ensure either the AC line cord plug or the appliance coupler are accessible in case of emergency disconnect requirement. 12- Use only attachments/accessories specified by QSC Audio Products, Inc. 13- Use only with hardware, brackets, stands, and components sold with the apparatus or by QSC Audio Products, Inc. 14- Unplug the apparatus during lightning storms or when unused for long periods of time. 15- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug 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. 16- Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation or placement. Any such condition severely reduces the safety of the installation and should be immediately corrected. Use only hardware which is rated for the loading conditions of the installation and any possible short-term, unexpected overloading. Never exceed the rating of the hardware or equipment. 17- Consult a licensed, Professional Engineer regarding physical equipment installation. All local, state and national regulations regarding the safety and operation of equipment are understood and adhered to. 18- HPR152i WARNING! Do not use a loudspeaker support pole longer than 26” (660mm) when supported by QSC’s HPR151i or HPR181i subwoofer. 19- HPR122i WARNING! Do not use a loudspeaker support pole longer than 31” (787mm) when supported by QSC’s HPR151i or HPR181i subwoofer. 20- Do not use the HPR152i, HPR153i, HPR151i, or HPR181i oriented horizontally. Horizontal orientation can cause overheating and thermal limiting. The cooling fins on the amplifier module must be vertically oriented in order to efficiently dissipate the heat generated by the amplifier. 21- The appliance shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases, shall be placed on the apparatus. 3 Introduction Congratulations and thank you for your purchase of this professional, powered loudspeaker product.
