[. . . ] is not liable for any damage to amplifiers, or any other equipment that is caused by negligence or improper installation and/or use of this loudspeaker product. ("QSC") guarantees its products to be free from defective material and / or workmanship for a period of three (3) years from date of sale, and will replace defective parts and repair malfunctioning products under this warranty when the defect occurs under normal installation and use - provided the unit is returned to our factory or one of our authorized service stations via pre-paid transportation with a copy of proof of purchase (i. e. , sales receipt). This warranty provides that the examination of the return product must indicate, in our judgment, a manufacturing defect. This warranty does not extend to any product which has been subjected to misuse, neglect, accident, improper installation, or where the date code has been removed or defaced. [. . . ] Gently and evenly work the grill out of its retaining groove to avoid bending the grill. 3- Reach into the waveguide's port and pull gently to remove the waveguide. Be careful not to damage the connections, wiring, or the gasket between the waveguide and the cabinet. 4- Rotate the horn 90° clockwise or counter clockwise and set it back in place. Make certain the wiring is not stressed or pulled loose from its connections. 5- Before reinstalling the waveguide screws, lift the assembly a small distance and make sure that the gasket is properly in place. 6- Replace the grill. Logo Badge Rotation The logo badge on the grill screen can be removed, rotated, and reinstalled. 3 Connection The I-82H has two Speakon® NL4-type connectors wired for full range, passive operation. Connect the amplifier's + and - outputs directly to the Speakon's 1+ and 1- terminals. The two connectors are wired in parallel to make parallel cabinet connection easy. Your amplifier must be able to safely power the lower impedance of parallel-connected loudspeakers. EN NL4 to NL4 Wiring (two- and four-conductor cables) Two- or four-conductor cable may be used for Speakon to Speakon connections. Four-conductor cable can be used, but the extra conductors do not carry signal. The I-82H is not wired for biamp operation. Do not connect biamplified equipment to the I-82H. To Amplifier To Loudspeaker Banana to NL4 Wiring To Amplifier To Loudspeaker 1/4" Phone to NL4 To Amplifier To Loudspeaker Maintain proper speaker and amplifier connection polarity throughout the entire system. All positive-marked loudspeaker terminals should be connected to positive-marked amplifier output terminals. This will provide the best possible low-frequency output from your system. 4 Mounting Stand Alone Mounting If using the loudspeaker only, it can be set on any appropriate surface. The cabinet will lean back at a slight angle when set on a flat surface. Install the four self-adhesive rubber feet on the cabinet bottom to stabilize the loudspeaker and to help prevent it from moving due to cabinet vibration at high output levels. On the back of the loudspeaker, near the bottom, is a safety cable attachment point. Install a safety cable strong enough to support several times the weight of the loudspeaker assembly in the event it may fall. The cable must be secured to a secondary support point which is also strong enough to support several times the loudspeaker's weight. ENSURE THAT THE LOUDSPEAKER IS MOUNTED PROPERLY AND A SAFETY CABLE IS INSTALLED TO RETAIN THE LOUDSPEAKER IN THE EVENT OF A MOUNTING FAILURE. Ensure the mounting surface and supporting structure are appropriately strong enough to support the loudspeaker assembly and any potential vibration or seismic activity. [. . . ] Ensure the safety cable, cable attachment technique, securing hardware, and attachment points are strong enough to support several times the weight of the loudspeaker in the event of a primary-mount failure. 6 I-82H Loudspeaker Dimensions EN I-YM8 with I-82H Loudspeaker Dimensions 7 Specifications Frequency Response : 1 80- 21k Hz (-6 dB) 60- 22k Hz (-10 dB) 113 dB SPL continuous rms output 119 dB SPL peak output 8 ohms nominal 7. 0 ohms minimum, 210 Hz 135 ohms maximum Maximum Output : (calculated) 2 Impedance: EN Power Rating : rms (IEC 100 hrs): recommended amp power: 3 200 watts rms 400 watts rms 90. 5 dB, 1 watt, 1 meter, free field (4 pi) 500 Hz 1000 Hz 2000 Hz 4000 Hz 8000 Hz 16000 Hz 500 Hz 1000 Hz 2000 Hz 4000 Hz 8000 Hz 16000 Hz 4. 0 5. 5 11. 7 8. 9 8. 6 7. 2 2. 5 3. 6 14. 7 7. 7 7. 3 5. 3 Sensitivity: Directivity Index: Q: Weight: I-82H: 17. 5 lb. Alternatively, the inside of the grill can be completely masked and set in place on the loudspeaker enclosure for painting. Be careful not to get water on or into either of the drivers or the input connections. 6- Scuff-sand the components to be painted using red Scotchbrite® pad or 320 - 400 grit sandpaper. [. . . ]
