This product will provide you many years of useful service with proper use and care. Please read this manual completely and become familiar with the design and operation of this advanced active speaker system. The P.Audio CXP series was designed to bring a truly world class level of performance to the P.Audio loudspeaker enclosure range. The 121C and 151C coaxial models employ large format ferrite magnets and a thru pole piece compression driver mounting for near perfect time alignment between the woofer and compression driver. The P.Audio CXP-21Sub brings a new level of performance to both portable and installed sound in the form of the large 21 inch woofer, which provides extreme low end, high power handling and very high sound pressure level capabilities, whilst using all of P.Audio s expertise in world class component design to ensure very high reliability. The CXP-122F and CXP-152F passive models provide high peak power handling when enough amplifier power is available. This combined with P.Audio s unique insight into minimizing time domain resonances and imperfections through well-conceived woofer and horn designs give these models very high intelligibility and highly dynamic performance. Information regarding these models can be found at P.Audio s website The CXP range of products are suitable for both portable and fixed installation indoor environments such as night clubs, pubs, meeting halls and general live performance applications.

P.Audio is continually looking to improve products, so specifications are subject to change without notice.

5 3. SETUP AND USE OF THE CXP PRODUCTS 3.1. AC MAINS CONNECTION NOTE: The powered models in the CXP series use an automatic switching power supply. ONLY the 3 pin mains power lead supplied with the unit may be used. DO NOT SUBSTITUTE AC MAINS POWER CONNECTION LEADS. Prior to connecting the AC mains cable, ensure that the AC mains switch is in the OFF position. The CXP range of products will operate on AC mains voltages of 115 volts to 230 volts. The required AC mains frequency is between 45 Hz and 65 Hz. The acceptable voltage range is 85VAC-265VAC. The amplifier s switch mode power supply (SMPS) will automatically adjust to the mains voltage present. The powered CXP enclosures use a standard powercon type connector system. To mate the AC mains cable with the AC mains connector on the amplifier, simply align the plug with the panel s connector, insert into the connector and rotate clockwise through 90 degrees. The cable locking system should engage, ensuring the cable will not be removed accidentally. Always support the enclosure with one hand whilst performing this operation. The AC mains connector is shown above. To disconnect the cable end of the AC mains connector pull back on the spring loaded locking system and rotate 90 degrees anticlockwise, before removing completely. NOTE: ALWAYS turn off the AC mains power BEFORE attempting to disconnect the AC mains cable from the CXP amplifier module! NOTE: DO NOT CONNECT THE AC MAINS END OF THE AC MAINS CABLE IN AN AREA THAT IS WET OR SUBJECT TO CONDENSATION OR DAMP CONDITIONS! NOTE: Always ensure the cable has enough slack. The automatic locking feature of the cable ensures a tight fit, and very secure operation, but also means that the cable will not release only through tension on the cable. Leave enough slack to allow for accidents. In order to use the power link feature on the CXP series cabinets, a separate powercon cable must be purchased. This cable will have a powercon output and powercon input connector on either end. A MAXIMUM of 3 cabinets may be daisy chained using the powercon output connector, including the first cabinet (total of 3 cabinets on 1 line). Never attempt to link more than 3 cabinets. Once the AC mains cable is securely connected to both the amplifier and AC mains supply, the amplifier may be turned on. It is good practice to make certain that the audio levels on the mixer s output (or other source output) are reduced or muted prior to applying power. The pilot light is located on the rear panel.

6 NOTE: If the pilot light does not illuminate within 30 seconds the unit may be in a FAULT CONDITION. If this occurs, the unit should be returned to P.Audio for evaluation. THERE ARE NO USER-SERVICABLE PARTS INSIDE. DO NOT REMOVE THE AMPLIFIER MODULE! (See the section below Replacement of Components for more detailed information) AUDIO CONNECTIONS The CXP amplifiers include both male and female XLR-type connectors. Any standard XLR-type cable end connectors may be used. The image below illustrates the inputs found on the amplifier plate. Line Input and Line Output (THRU) are shown. All the necessary EQ is provided in the on board pre amp. A line level input of voltage 0.775v will drive the on board amplifiers to full power. The CXP input section also allows for paralleling multiple powered enclosures together. This function is achieved by using the Line Output XLR-type connector located next to the input XLR-type connector on the amplifier module. The output level can be controlled using the level control knob, or using remote software (see section REMOTE SOFTWARE). For example, if 2 CXP-21Sub and 2 CXP-121C were used for a front of house system, the XLR signal lead can be linked to each enclosure. The correct preset should then be selected on each enclosure, for example: CXP-21 Sub: Preset 2 Flat with CXP-121C/CXP-151C CXP-121C: Preset 2 Flat with subwoofer (High Pass at 100Hz)

7 4. REMOTE SOFTWARE DSP.AUDIO The remote control software enables the user to adjust EQ, delay, polarity, noise gates and other aspects of the CXP series enclosures performance. Once the unit is connected to the computer, any changes made on the computer will become active, but will NOT be saved onto the amplifier, until the preset is stored onto the CXP series amplifier HARDWARE REQUIREMENTS Essential: Windows computer running windows XP or newer operating system. At this time, compatibility with windows 8.1 is not guaranteed. Spare hard drive space of 50MB Recommended: RAM 2GB Operating System Windows 7 Processor Dual core 2gHz or higher 4.2. COM CABLE The COM cable is an accessory, available from P.Audio, which allows the user to take control of the CXP series amplifiers from any windows based PC. Upon connecting the COM cable and opening dsp.audio software, a dialog screen will appear checking options for connecting to the device in question. To ensure communication occurs on the right COM cable, this must be selected from the drop down list. For linking between amplifiers, standard CAT5 type cabling can be used. To connect the COM cable to the CXP series amplifiers, simply connect the USB plug to the windows computer, and plug the other end into the socket on any available CXP series amplifier. Ensure to align the plug correctly and do not exert too much force onto the USB plug ID Once the required amplifiers are all linked together, the software can be started. To start the software, click start All Programs dsp.audio dsp.audio Application. Once the COM cable is chosen, the software needs to know which units to communicate with. ID for CXP series amplifiers as set by the factory range from 1-32, although the user to is free to change this as they see fit with the configure ID Device utility. The software can communicate with a maximum of 32 units at once. Once all is set up, press OK and the software will launch.

8 4.4. CONTROLLING THE CXP SERIES SPEAKERS Once the software is up and running, all connected speakers will be seen in the ID list to the left hand side of the screen. All parameters available to the user will be available by double clicking the device required to monitor, and the parameters screen will be displayed. Across the top of the parameters window, there are several options available to the user: Load Allows loading of a preset file from a storage location such as the computer hard drive. Save Allows saving of the current parameters to a file in a storage location such as the computer hard drive. Store Allows storing of the current parameters to a preset location on the amplifier. Locations are provided to the user to enable this, and avoid writing over any factory presets. Once a preset is overwritten, the original preset file must be used to recover the data. Recall Loads a preset from the amplifier memory, remotely. This allows presets to be changed on units in inaccessible locations. However, once the COM cable is removed, the unit will revert back to the preset as indicated by the knob on the unit itself. Setup This is largely a factory operation to switch the amplifier from two-way to bridged mode. This is not required by the user unless some drastic last minute servicing is required. Name Device This allows the user to change the name for each device, and this is stored in the amplifier memory. The name will also be changed in the ID list to allow for easy identification. From the parameters page, the following parameters can be adjusted: Noise Gate Allows the user to cut out background noise when the device is not in use. This can be especially useful when a lot of open microphones are picking up crowd noise, or making a stage very noisy. Input Source Allows the user to select between a noise source and the analog input. The noise source is especially useful when tuning the system to a particular room, or for fault finding. Noise Generator Provides level control and noise type when noise generator is selected as the input. Phase Polarity switching is allowed with the option of 0 or 180 degrees. Delay Delay can be specified in both time and distance.

9 DLF DLF is a set of filters tuned specifically to make recorded music sound more dynamic at low levels. In the music presets on the amplifier, this option is turned on. High Pass Filter All of the cabinets already have a high pass filter programmed in, but an extra high pass filter is provided to the user for crossover, or extra subsonic filtering. 5 Band Parametric EQ Q factors up to 10 are available to give the user complete control over the sound of their system. Mute On CXP-151C and CXP-121C, separate mute controls for low and high are available. On CXP-21 Sub, a single mute control is available PROTECTION In installation, or when the operator is away from the desk, it is understandable that protection will be desired to ensure other users do not get unwanted access. If the LOCK button is pressed, a password prompt will be shown. To block use to all features of the software (only signal monitoring will be seen), please use the password: dspamp For advanced users only (not recommended): to gain access to the individual processing for the transducer components, please use password: outamp For very advanced users only (not recommended): to gain access to master compressor/limiter settings, please use password: limamp

10 5. RIGGING AND SUSPENSION The CXP Series (with the exception of CXP-21 Sub) features M10 (metric) steel rigging points. The enclosures (EXCEPT CXP- 21Sub) may be suspended for either temporary installation or permanent installation. Suspension of the CXP Series should be attempted ONLY by someone familiar with overhead suspension of products and familiar with local and national codes associated with suspension of products. All associated rigging is the responsibility of others! DO NOT SUSPEND THE CXP PRODUCTS UNLESS YOU ARE EXPERIENCED WITH OVERHEAD RIGGING AND UNDERSTAND AND OBEY ALL GENERALLY ACCEPTED SAFETY PRACTICES! The CXP 121C, 151C, 122F, 152F may be mounted to any high-quality loudspeaker stand with a standard inch (35 mm) diameter mounting pole that is capable of supporting the weight of the enclosure. The mounting pole MUST be located on a level surface that is capable of safely supporting the weight of both the loudspeaker stand and the enclosure. DO NOT ADD OR SUSPEND ANY ITEMS TO THE ENCLOSURE OR LOUDSPEAKER STAND. These enclosures may also be suspended using the M10 Eye bolt kit available from P.Audio. DO NOT SUBSTITUTE SUSPENSION HARDWARE. The CXP-21Sub is intended to be used with a standard M20 screw thread style satellite pole mount (available from P.Audio) for mounting the CXP-121C, 151C, 122F, or 152F above it. The CXP-21Sub MUST be located on a level surface that is capable of safely supporting the weight of both the CXP-21Sub and the mid-hi speaker. WARNING: The pole used to mount the mid-hi enclosure must NOT be more than 0.8 meters (31.5 inches) long. DO NOT use a pole that is longer than 0.8 meters! DO NOT PLACE ANY OTHER LOUDSPEAKERS, EXCEPT THE CXP SERIES on the CXP-21Subs POLE. WARNING: DO NOT ATTEMPT TO SUSPEND P.AUDIO PRODUCTS WITHOUT UNDERSTANDING LOCAL AND NATIONAL CODES THAT APPLY TO OVERHEAD SUSPENSION OF PRODUCTS. DO NOT ATTEMPT TO SUSPEND P AUDIO PRODUCTS UNLESS YOU ARE A PROFESSIONAL WITH KNOWLEDGE OF LOCAL AND NATIONAL CODES RELATED TO SAFE SUSPENSION AND ARE EXPERIENCED IN SUSPENDING PRODUCTS OVERHEAD. WARNING: The CXP PRODUCTS are intended for indoor suspension ONLY! DO NOT suspend or attempt a permanent installation in an outdoor environment! P.AUDIO IS NOT RESPONSIBLE FOR FAILURES RELATED TO NON-COMPLIANCE WITH LOCAL AND NATIONAL CODES AND SAFE SUSPENSION PRACTICE. ALL ASSOCIATED RIGGING IS THE RESPONSIBILITY OF OTHERS. 6. APPLICATION AND TROUBLE SHOOTING TIPS The CXP Series makes up components of a high-quality professional sound reinforcement system designed for use in both indoor, and dry outdoor applications. Some basic precautions will insure long-term reliability. EQUALIZATION AND GAIN The CXP-121C and 151C have all the required equalization and gain functions included in the internal analog signal processing circuits. Both the equalization and gain functions have been optimized for flat frequency response and maximized system dynamics. If distorted sound is heard the gain and EQ settings on the outboard mixer and any other external equipment should be carefully checked to ensure that the input section of the CXP-121C/CXP-151C is not overloaded. If additional equalization is required, care should be taken to avoid excessive EQ in any frequency band, but particularly at low frequencies. Excessive equalization can produce band selective clipping and distortion. All EQ boost levels should be monitored if system distortion is present. Applications that require excessive low frequency equalization are almost always an indication that a sub woofer is required. P.Audio offers the CXP-21Sub; a companion product for use with the CXP Series and it will provide substantial low-frequency acoustic output.

11 PROBLEM: Distorted sound When input levels to the CXP amplifiers exceed V RMS for line level inputs it is possible to produce system clipping or overdrive. It is still possible to overdrive the input section of the enclosure. If distorted sound is present the following steps should be taken: 1. Verify that the mixer s output is not clipping or overloaded. If the output metering section of the mixing console is continuously in the red then the output level should be reduced. (occasional red indications are usually fine and are dependent on the mixing console s output capability). 2. Verify that excessive equalization is not present anywhere in the signal chain. 3. Verify that AC mains levels are within the required range. Voltage measurements on the AC Mains should be performed by a licensed electrician or individual trained in making high-voltage measurements. PROBLEM: No sound from active units 1. Verify that the amplifier pilot light is on. 2. Verify that there is AC Mains voltage on the AC Mains input to the amplifier. NOTE: NOT DO ATTEMPT TO REPLACE THE FUSE. THERE ARE NO USER SERVICABLE PARTS INSIDE THE CXP SERIES AMPLIFIERS. 7. PRODUCT SERVICE There are NO user-serviceable parts inside the CXP Series amplifiers. However, the amplifier does need to be removed in case of compression driver service. See notes below for compression driver service and repair (Replacement of Components). The CXP amplifier module MUST be serviced by a company authorized by P. Audio. Replacement of Components REPLACEMENT OF COMPONENTS MUST BE PERFORMED BY A QUALIFIED TECHNICIAN OR ONE KNOWLEDGABLE IN THE REPLACEMENT OF TRANSDUCER COMPONENTS! DO NOT ATTEMPT ANY REPAIRS UNLESS THE CXP SERIES AMPLIFIER HAS BEEN DISCONNECTED FROM THE AC MAINS SOURCE! In the event of woofer failure or compression driver failure, the woofer may be accessed by removing the front grille and then removing the coaxial drive unit. This should be done by a qualified technician or contractor. There is no need to remove the amplifier panel in the event of a woofer failure, or compression driver failure. USE EXTREME CARE WHEN HANDLING THE CXP AMPLIFIER MODULES. THE COMPONENTS ARE FRAGILE AND THE MODULE MUST NOT BE SET DOWN ON THE COMPONENT SIDE OR DAMAGE WILL OCCUR! NOTE: The powered models in the CXP series feature an internal fuse to protect the power amplifier. THE INTERNAL FUSE IS NOT USER REPLACABLE. UNDER NO CIRCUMSTANCES SHOULD THE AMPLIFIER PANEL BE REMOVED FROM THE CABINET.

12 Care should be exercised when disconnecting the amplifier module from both the woofer and the compression driver. Be sure to observe the wiring polarity of both the woofer and the compression driver. The compression drivers are of a screw on type and are easily removed once the woofer has been removed. Ensure that both the woofer and compression driver are wired with the correct polarity observed after replacement. Thank you once again for purchasing this P.Audio product.
