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 i...

9 AC Mains Connect AC power to the IEC socket on the back of the amplifier by locating the IEC connector-end of the AC power cord and inserting it fully into the IEC inlet on the power amplifier module. NOTE: Turn off the AC power switch before connecting AC power. The V-LOCK power cord has a specia...

10 Input Connections K8, K10, K12 The K8, K10 and K12 are designed to accept MIC Level and Line Level inputs with several different connectors. There are three input connection points on the input panel. Channel A will accept MIC or Line Level inputs by connecting a male XLR cable or a male 1/4"...

12 Output Connections K8, K10, K12 Both Channel A and Channel B have discreet direct outputs on female XLR connectors. The signal on this output is exactly equivalent to the signal from the corresponding input. The level of the output signal is not affected by the gain setting for that channel. Addi...

13 DSP Features The K Series features advanced DSP (digital signal processing) circuitry that performs many functions. Some functions are set at the design/production level and are not user accessible. These functions include crossovers, time alignment, limiting and protection, thermal management an...

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...

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. The voltage on t...
