The QSC KW Series SUS KIT 122 is a specialized suspension kit designed to facilitate the safe and secure installation of QSC KW122, KW152, and KW153 Loudspeaker Systems. This kit is essential for both vertical and horizontal suspension applications, ensuring that the loudspeakers are mounted from a solid, structural foundation. The primary function of the kit is to provide the necessary hardware and instructions for securely attaching the loudspeakers to overhead structures, allowing for optimal sound dispersion and system integration in various environments.
For the KW122 Loudspeaker System, the kit supports both vertical and horizontal suspension. In a vertical orientation, the loudspeaker can be suspended using three M10 eyebolts. Two eyebolts are installed on the top surface of the enclosure, replacing factory-installed M10 flat-head screws. The third eyebolt, designated as the pull-back eyebolt, is installed at the rear of the enclosure, just below the amplifier module. This configuration allows for a straightforward vertical hang, ensuring stability and proper alignment. It is crucial to tighten the eyebolts until their shoulders are snug against the enclosure and then rotate them to the desired position for optimal orientation. Importantly, no washers or the Pull Back Bar are used when vertically suspending the KW122 loudspeaker, simplifying the installation process for this specific orientation.
When suspending the KW122 in a horizontal position, the installation becomes slightly more involved, requiring the use of the Pull Back Bar in addition to the eyebolts. This orientation allows the loudspeaker to be suspended with the LF Driver positioned to either the left or right, offering flexibility in system design. For horizontal suspension, two top-surface eyebolts are installed on one of the side panels, which then becomes the top surface. The Pull Back Bar is attached to the same M10 installation location on the side of the enclosure. The installation of the Pull Back Bar involves removing a factory-installed M10 flat-head screw and then attaching the bar using an M10 Hex Socket, Button-head screw, along with an M10 Lock Washer and M10 Flat Washer. A KW122 Pull Back Gasket is applied to the Pull Back Bar, ensuring a secure and vibration-dampening interface between the bar and the loudspeaker enclosure. The gasket should be carefully aligned with the hole in the Pull Back Bar before attaching it to the enclosure. Once the Pull Back Bar is bolted to the enclosure, an eyebolt is inserted into the bar and secured with an M10 hex nut, lock washer, and flat washer. The "eye" of this eyebolt must be oriented towards the two top eyebolts installed on the enclosure, ensuring proper alignment for the horizontal hang. The detailed steps for attaching the Pull Back Bar, including test fitting and ensuring perpendicular alignment, are critical for a safe and stable horizontal suspension.
For the KW152 and KW153 Loudspeaker Systems, the kit primarily addresses vertical suspension, allowing the LF Driver to be on either the top or bottom. Similar to the KW122's vertical setup, three M10 eyebolts are used. Two eyebolts are installed on the top surface of the loudspeaker enclosure, replacing existing M10 flat-head screws. The third eyebolt, the pull-back eyebolt, is installed at the rear of the enclosure, just below the amplifier module. An optional threaded insert just above the amplifier module can also be used for the pull-back eyebolt. For these models, no flat washer or standoff is used on the pull-back eyebolt, streamlining the installation. The tightening procedure for the eyebolts remains consistent: snug against the enclosure, then rotated to the desired position.
The kit also provides instructions for horizontal suspension of the KW152 and KW153, which mirrors the process for the KW122. Two top-surface eyebolts are installed on the side that becomes the top, and a pull-back eyebolt is installed at the rear, just above the amplifier module. The emphasis on proper tightening and orientation of the eyebolts is consistent across all models and suspension types, highlighting the importance of secure connections for safety.
Maintenance features for the QSC KW Series SUS KIT 122 primarily revolve around ensuring the integrity and safety of the installation over time. Before any installation, rigging, or suspension, a thorough inspection of all hardware, suspension components, enclosures, transducers, brackets, and associated equipment is mandated. This includes checking for any missing, corroded, deformed, or non-load rated components, as these can significantly compromise the strength and safety of the installation. Any such conditions must be corrected immediately to prevent severe safety risks. Users are explicitly warned to use only properly rated hardware for the specific loading conditions of the installation and to never exceed the rating of the hardware or equipment.
The manual strongly advises consulting a licensed Professional Engineer for physical equipment installation to ensure compliance with all local, state, and national regulations regarding equipment safety and operation. This professional oversight helps to mitigate risks associated with improper installation. Furthermore, the kit emphasizes the use of load-rated hardware exclusively for attaching to the eyebolts or Pull Back Bar, and strictly prohibits suspending products from any structural element of the loudspeaker enclosure other than the designated load-rated M10 suspension points. Adherence to proper lifting techniques and technologies is also highlighted as a crucial aspect of safe maintenance and installation.
The kit's instructions are meticulously detailed, using specific terminology to guide the user. "WARNING!" indicates instructions critical for personal safety, where non-compliance could lead to bodily injury or death. "CAUTION!" points to instructions that, if not followed, could result in damage to physical equipment not covered under warranty. "IMPORTANT!" signifies instructions vital for successful operation, while "NOTE" provides additional useful information. These distinctions help users understand the criticality of each step and ensure a safe and effective installation and maintenance process. The overall design and instructional approach of the QSC KW Series SUS KIT 122 prioritize safety, precision, and long-term reliability for professional audio installations.
