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.

All three models are equipped with two 35 mm pole sockets that allows use on a speaker stand or on a pole over a subwoofer. (The subwoofer must have a 35 mm pole socket capable of supporting the loudspeakers.) One socket is for vertical mounting, the other for tilting the enclosures down 7.5 degrees. (RefertoFigure 5)

In addition, the K.2 Series have features designed for various suspension methods. They feature two M10 threaded inserts for suspension with eyebolts and a built-in pull-back ring. There are also yoke accessories (model numbers: K8.2 YOKE, K10.2 YOKE, K12.2 YOKE) for each model that can mount either to the sides of the cabinet or to the top and bottom. These yokes allow for rigid mounting to structures and rotation of the speaker system. (Refer to Figure 6 andFigure 7)

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. Maximum ambient temperature for full performance to speciﬁcation is 50° C (122° F). Do not install enclosures where exposed to rain or other water sources. The enclosure is not weatherproof. Outdoor installations must provide protection from the elements.

AC Mains

Refer to Figure 10)

Connect the AC power cord to the IEC socket on the back of the ampliﬁer. Make sure the plug is fully inserted into the IEC socket on the power ampliﬁer module.

NOTE: Make sure that the AC power switch is in the OFF position before connecting AC power cord to the AC source.

Connect the AC Power cord to the facility’s AC outlet.

The V-LOCK power cord has a special latching feature to prevent the power cord from being unintentionally removed. The IEC plug and socket are both blue in color so the power cord can be identiﬁed as a K.2 Series loudspeaker cord. If the QSCsupplied cord is lost or damaged, a standard 18-gauge IEC power cord may be used. However, the latching system works only with a V-LOCK power cord. Available from QSC.

The K.2 Series loudspeakers are equipped with a universal power supply that can use input AC power voltages ranging from 100–240VAC at 50 – 60 Hz.

— Figure 10 —

WARNING!: Use only the power cable that is correct for your location.

AC Mains Disconnection

Push in on the bottom of the rocker switch to turn the powered loudspeaker off. Unplug the AC cable from the power source. To remove the AC mains cord from the ampliﬁer, grasp the IEC connector’s plastic body, press the yellow latch release button and pull.

Power Switch

Push in on the top of the rocker switch to apply AC mains power to the ampliﬁer. When power is applied to the ampliﬁer, the blue POWER indicator LED illuminates.

Rear LED POWER Indicator

The blue LED POWER indicator on the rear panel will illuminate when the AC Power is applied. The rear LED POWER indicator will extinguish when the AC Power has been removed.

If the rear LED POWER indicator does not illuminate within the ﬁrst 3 minutes after power is applied, verify the AC mains line cord is properly attached to the loudspeaker and plugged into the AC outlet. Verify the outlet is functioning properly.

NOTE: If the AC mains cord is usable and the AC mains outlet is operating properly, but the unit fails to operate, the loudspeaker may require servicing. Contact QSC’s Technical Services department.

TD-000523-01-F

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). The level controls on your mixer may now be brought up.

Power Off Sequence: Turn off “top boxes,” turn off subwoofer, then turn off all source devices.

If a K.2 Series speaker is being driven from the output of another K.2 Series unit, it should be turned on after the unit feeding it signal, and turned off before the unit feeding it signal.

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.

b. MIC LED – When illuminated

(yellow) it indicates the input is conﬁgured to accept a microphone input. When not illuminated, it indicates the input is conﬁgured for a line-level input. You can change the setting through the Menu. When MIC is selected, the MIC Pre-amp is activated, and the yellow MIC level LED illuminates. The MIC setting should only be used if a microphone is connected directly to the MIC/LINE input. Note that the input does not provide phantom power.

c. GAIN knob – Sets the sensitivity of Input A which controls the signal level sent to the ampliﬁer and the MIX OUT

(POST GAIN) output.

— Figure 12 —

3c 4 5

d. Combination XLR – 1/4” Phone Jack connector. Balanced XLR and 1/4” input. Accepts line-level or MIC-level

inputs. Select MIC or Line through the Menu.

CAUTION!: The MIC setting should only be used if a microphone is connected directly to the MIC/LINE input. Using the MIC setting for line-level may introduce distortion. Use caution when changing to the MIC selection in the Menu as the output level increases signiﬁcantly when MIC is selected.

2. Input B

a. GAIN knob – Sets the sensitivity of Input B which controls the signal level sent to the ampliﬁer and the MIX OUT

(POST GAIN) output.

b. 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.

c. HI-Z LED – When illuminated (yellow) it indicates the input is conﬁgured to accept a high impedance input, typically

a musical instrument. When not illuminated, it indicates the input is conﬁgured for a line-level input. You can change the setting through the Menu.

d. Combination XLR – 1/4” Phone Jack connector. Balanced XLR and 1/4” input. Accepts line-level and high

Impedance inputs. Select line level or high impedance through the Menu.

3. Input C

a. GAIN knob – Sets the sensitivity of Input B which controls the signal level sent to the ampliﬁer and the MIX OUT

(POST GAIN) output.

b. 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.

c. Stereo 1/8” (3.5 mm) TRS connector – Accepts line-level stereo input. Stereo input received at Input C is summed

to mono.

TD-000523-01-F

4. LIMITER LED – Illuminates (red) when the built-in limiter is activated to protect and avoid damage to the ampliﬁer or

TRS TS

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.

NOTE: Unless the gain controls of all active inputs are set to 0 dB, the output signal from the MIX OUT (POST GAIN) will not be at the same level as the input signal. If a “slave” speaker is intended to playback at the same level as the “master” speaker, the gain control on the “slave” speaker should be set to0 dB.
