PLACEMENT AND APPLICATIONS
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 that 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.
The CP Series is primarily designed for portable audio reinforcement. This includes a variety of
uses in reinforcement for entertainers and presenters. Both models are designed to perform well
on their own in full-range audio. They can be used as a single unit, in stereo pairs, or in distributed
or delayed systems.

Suspension
The CP Series loudspeakers are not designed to be suspended with eyebolts. However, the optional Yoke bracket can be mounted to a
suspended fixture.
OPERATION
Cooling
This is a powered loudspeaker, containing an internal power amplifier that produces heat. Allow a minimum of 6 inches (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. Maximum ambient temperature for full
performance to specification is 35° C (95° 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. Replacements are 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!

GAIN) output.
7.
LIMITER LED – Illuminates (red) when the built-in limiter is activated to 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 (green) 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 provide a +25 dB boost for microphones requiring a
higher input gain. When not illuminated, it indicates the input is configured for a line‑level input including microphones that provide a
standard line-level output. The MIC BOOST setting should only be used if a microphone is connected directly to the MIC/LINE input.
NOTE: The MIC/LINE input does not provide phantom power.
CAUTION! The MIC BOOST setting should only be used if a microphone is connected directly to the MIC/LINE input. Using
the MIC BOOST setting for line-level may introduce distortion. Use caution when changing to the MIC BOOST selection as the
output level increases significantly when MIC BOOST is selected.
10. MIC BOOST button – Switches between MIC BOOST level input and line-level input. When engaged, MIC BOOST LED is illuminated, and
MIC BOOST level (+25 dB) is selected for Input B. When disengaged, line-level is set for Input B.

Outputs
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.
Connect an Extension Loudspeaker to the MIX OUT (Post Gain)
Set the Gain controls of all inputs on the extension loudspeaker to 0 dB. When the Gains on the extension
loudspeaker are set to 0 dB, the extension's output level is the same as the master's output level. Control both
master and extension outputs using the master's Gain controls.
CAUTION! Do not connect the MIX OUT (Post Gain) of a CP Series loudspeaker
to any INPUT on the same unit. This output is designed to send the mixed signal to
OTHER CP Series units or to other audio equipment.
— Figure 14 —
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 (exceptions are documented in the text and the table below).
• 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.
TD-001571-01-B

•
•
•
•
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.”)
Dance Ext Sub – A voicing with low frequency enhancement and mid/high clarity more suitable for program material playback like pop
or electronic music, with an 80 Hz high-pass filter for use with an external subwoofer, for example, the KS112. (When MIC BOOST is
selected, input B contour changes to “Speech” while input A remains as “Dance.”)
Floor Monitor – A voicing for a full, balanced sound when used as a floor monitor, giving added stability when live microphones are
nearby.
Speech – A voicing (Input B only) that gives clarity and stability when used with either a hand-held dynamic microphone or headset
microphone. Input A/C remains on the Default voicing so that music or audio can pass through the loudspeaker simultaneously without
the Speech voicing being applied to it.
MIC BOOST
CAUTION! The MIC BOOST setting should only be used when a microphone is connected directly to the MIC/LINE input.
Using the MIC BOOST setting for line-level may introduce distortion. Use caution when changing to the MIC BOOST selection as
the output level increases significantly when MIC BOOST is selected.
MIC BOOST adds +25 dB to Input B when the MIC BOOST button is engaged. Some of the voicings for Input B change when MIC BOOST is
on. The table below shows the differences on Input B when MIC BOOST is on or off.
