Applications

The CP 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 3.

All three models are equipped with a 35 mm pole socket that allows use on a loudspeaker stand or on a pole over a

subwoofer. (The subwoofer must have a 35 mm pole socket capable of supporting the loudspeakers.) (RefertoFigure 4)

In addition, the CP Series have yoke accessories for each model that mount to the top and bottom. These yokes allow for

rigid mounting to structures and rotation of the loudspeaker system. (model numbers: CP8 YOKE and CP12 YOKE )

For portable installations, you can use the yoke knob to quickly and easily mount the loudspeakers on the yoke, or you

can use the yoke mounting bolt for more permanent installations. Each yoke has threaded inserts to store either the yoke

knob or the yoke mounting bolt. Refer to the CP Series Yoke Mounting Quick Start Guide TD-001570 for details.

Installation

WARNING!: Before placing, installing, rigging, or suspending any loudspeaker product, inspect all hardware,

suspension, cabinets, transducers, brackets 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

severely reduces the safety of the installation and should be immediately corrected. Use only hardware which is rated for

the loading conditions of the installation and any possible short-term, unexpected overloading.

Never exceed the rating of the hardware or equipment.

Consult a licensed, professional engineer regarding physical equipment installation. Ensure that all local, state and national

regulations regarding the safety and operation of loudspeakers and related equipment are understood and adhered to.

Deployment

The CP Series loudspeakers were designed to sit on the ﬂoor, stage, a subwoofer

enclosure, be yoke mounted, 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.

WARNING!: Do not use a loudspeaker support pole longer than the lengths

speciﬁed in the table below when supported by a subwoofer.

Suspension

The CP Series loudspeakers are not designed to be suspended from eyebolts.

However, the optional Yoke bracket can be mounted to a suspended ﬁxture.

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 in

locations that are 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 8)

Connect the AC power cord to the socket on the back of the ampliﬁer. Make sure

the plug is fully inserted into the 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.

If the QSC-supplied cord is lost or damaged, a standard 18-gauge IEC power

cord may be used. Available from QSC.

The CP 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.

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. Unplug the cable from the ampliﬁer.

Power Switch

Push in on the top of the rocker switch to apply AC mains power to the ampliﬁer.

Rear LED POWER Indicator

The green LED POWER indicator on the rear panel will illuminate when the AC Power is applied (AC cord connected,

power switch on). 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 15 seconds after power is applied, verify the AC mains

line cord is properly attached to the loudspeaker and plugged into the AC outlet. Verify the AC 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.

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 loudspeakers are “last on, ﬁrst off”.

Power On Sequence:

1. Bring the output level control of the mixer (or other audio source) feeding your loudspeakers to its minimum position.

2. Turn on all source devices (CD players, mixers, instruments)

3. Turn on subwoofer

4. Turn on the “top-boxes” (CP8 / CP12).

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

Power Off Sequence:

1. Turn off “top boxes,”

2. Turn off subwoofer,

3. Turn off all source devices.

If a CP Series loudspeaker is being driven from the output of another CP Series unit, it should be turned on after the unit

feeding it signal, and turned off before the unit feeding it signal.

TD-001571-01-A

Inputs

The CP 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 9

1. Input 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.

2. Input A – Combination XLR – 1/4” Phone

Jack connector. Balanced XLR and 1/4”

input. Accepts line-level inputs.

3. Input 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.

4. Input B – 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.

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

summed to mono.

6. Input A + C GAIN knob – Sets the sensitivity of Input A and Input C which controls the signal level sent to the

ampliﬁer and the MIX OUT (POST GAIN) output.

7. 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.

8. POWER LED – Illuminates (blue) when power is applied to the unit and the ON/OFF switch is in the ON position.

9. MIC BOOST 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. The MIC setting should only be used if a

microphone is connected directly to the MIC/LINE input.

NOTE: The input does not provide phantom power.

10. MIC BOOST button – When engaged, this selects MIC level (+25 dB) for Input B.

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 as the output level increases

signiﬁcantly when MIC is selected.

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” loudspeaker is intended to playback at the same level as the “master”

loudspeaker, the gain control on the “slave” loudspeaker should be set to0 dB.

Outputs

1. MIX OUT (Post Gain) output XLR is a mix of Channels A, B, and C. Produces a line-

level output signal that is Post Gain. Any adjustments made to the gain of any of the three

channels affects this output signal. This output does not contain any DSP processing.

CAUTION!: Do not connect the MIX OUT (Post Gain) of a CP Series loudspeaker

to any INPUT of the same unit. This output is designed to send the mixed signal to

OTHER CP Series units or to other audioequipment.

CP Series Contour Selections

The CP Series loudspeakers offer six different voicing contours to use with speciﬁc applications. Below is a list of these

contours and a description of each. The contour settings affect both inputs.

• Default – The standard, factory voicing of the loudspeaker for use with live music, program music, or instruments.

• Default Ext Sub – The standard, factory voicing of the loudspeaker with an 80 Hz high-pass ﬁlter for use with live

music, program music, or instruments, and an external subwoofer, for example, the KS112.

• Dance – A voicing with low frequency enhancement and mid/high clarity more suitable for program material playback

like pop or electronic music. (When Mic Boost is selected, input B contour changes to “Speech” while input A remains

as “Dance.”)
