Use only QSC’s M10 forged shoulder eye bolts. Contact QSC Technical Services department for complete information. Cooling This is a self-powered loudspeaker containing an internal power amplifier that produces heat. 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 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. Do not install enclosures with their rear panels exposed to direct sunlight. Direct sunlight will heat the amplifier module and reduce its ability to produce full output. Install sunshades if the application merits. Maximum ambient temperature for full performance to specification is 40° C. (104° F.). Do not install enclosures where exposed to rain or other water sources. The enclosure is not weatherproof. Outdoor installations must provide protection from the elements.

NOTE: Turn off the AC power switch before connecting AC power. The V-LOCK power cord has a special latching feature to prevent the power cord from being unintentionally removed. The IEC plug and socket are both blue in color so the power cord can be identified as an HPRi loudspeaker cord. If the QSC-supplied cord becomes lost or damaged, a replacement 18 gauge IEC power cord may be used. However, the latching system will only function with a V-LOCK power cord available from QSC Audio Products. The correct AC line voltage is shown on the serial number label, on the rear panel. Connecting to the wrong line voltage may damage the amplifier or increase the risk of electric shock. AC Mains Disconnection Turn the AC power switch to the off position. To remove the AC mains cord, grasp the IEC connector’s plastic body, press the yellow latch release button and pull, removing the connector from the socket. Power Switch Push in on the top of the rocker switch to apply AC mains power to the powered loudspeaker. Push in on the bottom of the rocker switch to turn the powered loudspeaker off. When turned on, the blue POWER indicator LED and the red LIMIT (limiter) indicator LED will illuminate; after a few seconds the red LIMIT indicator will extinguish. LED POWER Indicator The blue LED POWER indicator will illuminate when the AC Power switch is in the “ON” position, the AC mains power cord is connected properly, and the AC mains are functioning properly. The LED POWER indicator will extinguish when the AC Power switch is in the “off” position or AC mains power has been removed from the loudspeaker. If the POWER indicator does not illuminate when the Power switch is placed in the “on” position, verify the AC mains line cord is properly attached to the loudspeaker and plugged into the AC outlet. Verify the outlet is functioning properly. If the AC mains cordset is serviceable and the AC mains outlet is operating properly, but the loudspeaker fails to operate, the loudspeaker may require servicing. Contact QSC’s Technical Services department. System Power Sequencing Proper power turn on sequence can help to prevent unexpected sounds from your system (pops, clicks, thumps). These unintended sounds can damage drivers and cause audience members to question the professionalism of the sound team. Turn on and off the system in the proper order to avoid unexpected sounds. Power On Sequence: Turn on all source devices (CD players, mixers), turn on subwoofer, then turn on the “top-boxes” (HPR122i, HPR152i and HPR153i). AC power switch Power “on” indicator LED To remove AC cord, press the yellow latch release button and pull on the connector body. 9 Input Connections Full-range models have one female XLR line-level input marked FULL RANGE LINE IN. Subwoofers have a second set of connectors, one for the left channel’s audio and one for the right channel’s audio. We recommend balanced connections be used. Balanced connections will reduce AC hum and interference, especially with long cable runs. Unbalanced connections may be suitable for short cables. The input impedance is 22k ohm for balanced connections or 11k ohm for unbalanced connections. The signal's source impedance should be less than 600 ohms. HPR122i, HPR152i and HPR153i: Insert the male XLR input into the jack marked FULL RANGE LINE IN. Ensure the connector is fully seated. HPR151i and HPR181i: Insert the left channel’s XLR input into the left channel’s (L) FULL RANGE LINE IN connector. Insert the right channel’s XLR connector into the right channel’s (R) FULL RANGE LIN...
