Applications The K.2 Series has been primarily designed for portable audio reinforcement. This includes a variety of uses in reinforcement for entertainers and presenters. All are designed to perform well on their own in full-range audio. They can be used singly, in stereo pairs or in distributed or delayed systems. They perform extraordinarily well as both main reinforcement systems and as floor monitors as shown in Figure 4.
Deployment The K.2 Series loudspeakers were designed to sit on the floor, stage, a subwoofer enclosure, be suspended, or be pole mounted on a 35 mm diameter loudspeaker support pole. If you are going to pole-mount on a subwoofer, refer to the chart below for specifics. K8.2 K10.2 K12.2 WARNING!: Do not use a loudspeaker support pole longer than the lengths specified in the table below when supported by a subwoofer. Subwoofers K.2 Series KS212C KW181 Maximum 36 in (914 mm) KSUB K8.
Cooling This is a powered loudspeaker containing an internal power amplifier that produces heat. Allow a minimum of 6" (152 mm) clearance at cabinet back for convection cooling. Keep anything that might restrict airflow away from the rear of the enclosure (i.e draperies, walls, etc.) CAUTION!: Do not install enclosures with their rear panels exposed to direct sunlight. Direct sunlight will heat the amplifier module and reduce its ability to produce full output. Install sunshades if needed.
System Power Sequencing Proper power turn on/turn off sequencing can help to prevent unexpected sounds from being produced by the system (pops, clicks, thumps). Always follow the rule that speakers are “last on, first off”. Power On Sequence: Bring the output level control of the mixer (or other audio source) feeding your speakers to its minimum position. Turn on all source devices (CD players, mixers, instruments), turn on subwoofer, then turn on the “topboxes” ( K8.2, K10.2 and K12.2).
Inputs The K.2 Series amplifier has three separate inputs; two combination XLR / 1/4” Phone Jack (Inputs A and B) and one 1/8” (3.5 mm) TRS jack (Input C). Refer to Figure 12 1. Input A a. SIG LED – When illuminated (green), it indicates a signal is present. If this LED is not illuminated, the input signal is missing or too low to detect. 2a 2b 2c 3a 3b 1a 1b 1c 3c 4 5 1d 2d b. MIC LED – When illuminated (yellow) it indicates the input — Figure 12 — is configured to accept a microphone input.
4. LIMITER LED – Illuminates (red) when the built-in limiter is activated to protect and avoid damage to the amplifier or loudspeaker. If the signal level at any frequency is too high, or the amplifier is too hot, the limiter is activated and the LED is illuminated. 5. POWER LED – Illuminates (blue) when power is applied to the unit and the ON/OFF switch is in the ON position.
Outputs 1. Channel B pass-through output connector. The signal here is the same as the input signal on Channel B. Use this to daisy-chain loudspeakers or to provide the signal to other audio equipment. 2. Channel A pass-through output connector. The signal here is the same as the input signal on Channel A. Use this to daisy-chain loudspeakers or to provide the signal to other audio equipment. 1 2 3 3. MIX OUT (Post Gain) output XLR is a mix of Channels A, B, — Figure 17 — and C.
