Suspension and mounting should be attempted only by those who are trained and skilled in safe suspension and mounting practices 7 - Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 8 - Only use attachments/accessories from QSC Audio Products, LLC. [. . . ] Consult the following illustrations. EN It is recommended that the yoke be attached to the mounting surface prior to attaching the yoke to the subwoofer enclosure. The yoke is designed to allow attachment to the mounting surface with mounting points ranging from 5. 5 in (140 mm) to 6. 5 in (165 mm) apart. 1 - Remove the screws from the selected attachment points using a #2 phillips-head screw driver or electric driver. Remove only the two screws that will be used for the attachment of the yoke. If a screw hole is left open, it will create an airleak which will cause noise and compromise the performance of the cabinet. 2 - Remove the adhesive backing from the rubber pad and attach the pad to the cabinet by pressing the adhesive coated side against the cabinet. Make sure not to obstruct the attachment holes. The adhesive will hold the pad in place as you mount the enclosure to the yoke. 3 - Align the yoke with the attachment points on the subwoofer and place the attachment hardware according to the illustration. Hex-head / phillips-head m6 Bolt Lock washer Flat washer Adhesive rubber pad (affixed to enclosure) 4 - Tighten the hex-head/phillips-head bolts enough to hold the subwoofer in place but loose enough to rotate with minimum force. Check the alignment of the subwoofer for best desired appearance. As long as the port is not blocked, the alignment of the subwoofer will not affect performance. Once positioned, tighten the bolts so that the subwoofer will not rotate with force. the yoke must be secured to structure that is capable of supporting the weight of the subwoofer and must be connected using load rated hardware. Consult a licensed, professional engineer when any doubt or questions arise regarding a physical equipment installation. Once the subwoofer is secured in position, the QSC logo can be rotated if desired. If the logo is difficult to rotate the first time, a tool may be required. A small flat-head screw driver is recommended. Gently work the tool between the logo badge and the grille to allow rotation. Exercise care to avoid scratching the grille surface. 5 Any unused attachment point can be used as a safety/seismic secondary attachment. Attach an eyebolt to an available attachment point according to the section of the manual titled: Suspending the Subwoofer Using Eyebolts and Shear Plates. Be sure to leave less than 12 in (300 mm) of slack in the secondary attachment cable. [. . . ] Strip the insulation for the signal wire so that approximately 3/4 in (20 mm) of bare wire is exposed. Place the bare wire under the screw down plate and retighten the screw as tightly as possible with a manual screw driver. The input and output pairs are parallel. The output terminals will pass exactly what is presented at the input terminals. [. . . ]
