User manual QSC AUDIO I-YM8 YOKE MOUNT

[. . . ] Any missing, corroded, deformed or non-load rated component could significantly reduce the strength of the installation, placement, or array. 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. [. . . ] Rotating the Waveguide to Alter HF Coverage Pattern 1- Remove the grill. Gently and evenly work the grill out of its retaining groove to avoid bending the grill. 2- Remove the eight waveguide retaining screws. A #2-size Phillips screwdriver is recommended. 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. Set the waveguide in place and reinstall the screws. 6- Replace the grill. Logo Badge Rotation The logo badge on the grill screen can be removed, rotated, and reinstalled. Using your fingers, pull the logo badge straight out. Rotate to the desired position and push back into place. 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. [. . . ] 5- Wash the components to be painted with a mild soap and hot water. 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. 7- Using compressed air, remove all dust from the components to be painted.
