Page 7: Installation
Installation Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers, brack- ets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation or placement. Any such condition severely reduces the safety of the installation and should be immediately cor- rected. - Page 8 Ensure all pick-point fasteners are installed and correctly tightened in order to maintain enclosure’s rated strength. Use either QSC’s M10 forged shoulder eye bolts contained in K SERIES M10 KIT or an M10 forged shoulder eyebolt with a thread length no more than 0.8 inch (20 mm).

Page 9: Power Switch
The IEC plug and socket are both blue in color so the power cord can be identified as a K Series loudspeaker cord. If the QSC supplied cord becomes lost or damaged, a standard 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, LLC. -

Page 14: Subwoofer Polarity
Subwoofer Polarity Polarity (sometimes improperly referred to as phase) refers to the voltage of an input signal and whether it is a positive or negative voltage at any given time. In most cases a positive voltage causes a woofer cone to move forward with respect to the cabinet orientation, and a negative voltage then moves the woofer cone backward. - Page 15 Remote Gain Attenuator A 3 pin “Euro” connector has been provided to adjust the volume of the K Series loudspeaker or put the system into standby. (Figure 13) By varying the voltage on the pin between +5V (provided on pin) and ground ( pin), the volume can be linearly controlled.
