6 Applications The K Series has been primarily designed for portable audio reinforce- ment. This includes a variety of uses in reinforcement for entertainers and presenters. The K8, K1 0 and K1 2 are all designed to perform well on their own in full-range audio.
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.
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.
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.
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. There are three input connection points on the input panel.
11 Balanced Inputs: Connect to the plug as shown. Unbalanced Inputs: Connect to the plug as shown. If a 3 conductor (TR S) plug is used to connect an unbalanced source, Pin 3 and pin 1 must be connected with a jumper as shown.
12 Output Connections K8, K1 0, K1 2 Both Channel A and Channel B have discreet direct outputs on female XLR connectors. The signal on this output is ex actly equivalent to the signal from the corresponding input. The level of the output signal is not affected by the gain setting for that channel.
13 DS P Features The K Series features advanced DSP (digital signal processing) circuitr y that per forms 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 and a number of proprietary features.
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.
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.
