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.

Free Standing
Refer to Figure 3
Use the angled side for floor monitor applications, or placed vertically on a stage, subwoofer or floor.

Pole Mounting
CP8 CP12
Refer to Figure 4 and Figure 5

Both models are equipped with a 35 mm pole socket that allows use on a loudspeaker stand or over a subwoofer with a 35 mm pole socket capable of supporting the loudspeakers. Refer to Table 1 for specifics about pole mounting the loudspeaker over a subwoofer.

WARNING! Do not use a loudspeaker support pole longer than specified in Table 1, when supported by a subwoofer.
Subwoofers

Yoke Mounting

The CP Series loudspeakers have yoke accessories that attach to the top and bottom of the loudspeakers. The yokes allow for rigid mounting to structure surfaces and loudspeaker rotation. (Models CP8 YOKE / CP12 YOKE)
For portable installations, use the Yoke Knob to quickly, and easily mount the loudspeakers on the yoke, 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 for details.

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! 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 AC Power is applied (AC cord connected, power switch on). The rear LED POWER indicator will extinguish when 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 emanation from the system (pops, clicks, thumps). Always follow the rule that loudspeakers are “last on, first off”.

Power-On Sequence:
NOTE: Steps 3 and 4 below are interchangeable depending on the order in which the top box and the subwoofer are wired.

1. Bring the output level control of the mixer, or other audio sources 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 the mixer may now be brought up.

Power Off Sequence:

NOTE: Steps 1 and 2 below are interchangeable depending on the order in which the top box and the subwoofer are wired.

1. Turn off “top boxes”.
2. Turn off subwoofer.
3. Turn off all source devices.

Inputs

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 inch TRS connector. Balanced XLR and 1/4 inch 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 inch TRS connector. Balanced XLR and 1/4 inch input.
   Accepts line-level and mic-level inputs.

5. Input C Stereo 1/8 inch (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 gain of Input A and Input C that 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 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.

11. Input B GAIN knob ­ Sets the gain of Input B that controls the signal level sent to the amplifier and the MIX OUT (POST GAIN) output.

Balanced Inputs

Connect the XLR plug as shown in Figure 10.

1.  Shield (ground)
2.  Positive
3. Negative
   

Connect the TRS (Tip Ring Sleeve) plug as shown in Figure 11. Do not use a TS 1/4 inch jack for balanced input.

1. Shield (for TRS jumper Sleeve to Ring)
2. Negative (for TRS jumper Ring to Sleeve)
3. Positive
   

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.

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.
• 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.

Input A, Input B Comparison With MIC BOOST On and Off

Contour| Input A| Input B| Input B (mic boost on)
Default| Default| Default| Default (+25 dB)
Default w/sub| Default w/sub| Default w/sub| Default w/sub (+25 dB)
Dance| Dance| Dance| Speech (+25 dB)
Dance w/sub| Dance w/sub| Dance w/sub| Speech (+25 dB)
Floor Monitor| Floor Monitor| Floor Monitor| Floor Monitor (+25 dB)
