7 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 sev[...]

8 Integrated Suspension P oints (suspended installations) The K8, K1 0 and K1 2 enclosures each feature three load-rated M1 0 installation points. As shipped from the factor y, each pick point has a rubber plug installed to retain the sleek look of the enclosure. These installation points are designed for use with the eyebolts included in the avail[...]

9 AC Mains Connect AC power to the I EC socket on the back of the amplifier by locating the I EC connector-end of the AC power cord and inser ting it fully into the I EC inlet on the power amplifier module. NOTE: T urn off the AC power switch before connecting AC power. The V-L OC K power cord has a special latching feature to prevent the po wer [...]

10 Input Connections K8, K1 0, K1 2 The K8, K1 0 and K1 2 are designed to accept MI C Level and Line Le vel inputs with several different connectors.

14 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 backw[...]

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 1 3) By varying the voltage on the pin between +5V (provided on pin) and ground ( pin), the volume can be linearly controlled. The voltage on the pin can be created by using a potentiomet[...]
