3. BEFORE YOU BEGIN: SAFETY AND CARE FOR YOUR CVP LOUDSPEAKERS

Positioning

High and upper mid frequencies are a crucial part of the audio spectrum, and have much to do with how perceive clarity and intelligibility. Whereas these frequencies are the most easily located, they are also the to be acoustically blocked. Taking the coverage angles of the models used into consideration, be sure to say your speakers so that the MF and HF drivers are free from obstructions and the higher frequencies can re entire audience (e.g. slightly above the heads of the audience). This will ensure optimal dispersion of higher-frequency content and thus improved speech intelligibility and clarity.

Avoiding Feedback

Always place the "front-of-house" speakers (the enclosures facing the audience) in front of the microphones, (e.g. towards the front edge of the stage). Use professional floor wedges (e.g. CVP-1152) or other dependent monitoring systems to ensure that the performers on stage can hear themselves. Whenever possible, positive monitor speakers so that they point only to the back side of microphones.

Avoiding Feedback When Using Turntables (e.g. DJ Applications)

Turntables often produce low-end feedback: low frequencies are fed back to the pickup arm and cartridge a reproduced again by the speakers. Common causes of low-end feedback are speakers positioned too close to the turntable or on wooden floors or stage elements prone to vibration. To avoid this, position the speakers from the turntable as possible. Placing them on a solid, non-resonating support will also help. If you are u CVP-1152 model speakers, try mounting them on stands. This will minimize direct contact between floor and speakers and reduce vibration.

Protecting Your Speakers

Next to following common-sense rules like exercising caution while setting levels to avoid overdriving your p amps, and understanding and respecting the physical limits of your system, there are a couple reliable met of protecting your speakers – and your entire system – using additional equipment. Using a high pass filter excessive low frequencies, low-frequency rumble or extreme low frequencies can lead to an excessive displacement of the speaker diaphragm and in turn to permanent damage. Using an equalizer or a low-cut pass filter to eliminate the low frequencies below the response curve of the speaker can effectively prevent Most consoles and outboard equalizers, as well as many other outboard signal processors and of course s management systems provide a high pass filter. The use of a high pass filter in the signal path is especially recommended when using turntables and/or CD players as signal sources. CD players often produce extrem low frequencies, which can lead to excessive diaphragm displacement. Using a limiter to limit the output le Insert the limiter between the mixing console output and your power amp. Many types of outboard signal processors and most speaker management systems include limiters for this application. Used properly, they eliminate overdriving of your audio signals and effectively suppress dangerous signal peaks, which can not degrade the sound quality, but also cause permanent damage to your speakers and other system compone

Power Amplifier Selection

Choosing the right power amplifier has a major effect on the performance of your speakers. The amplifier always provide at least as much power as the speaker system is capable of handling. In order to ensure reproduction of brief, high-power transients, the amp should provide about twice as much power as the speakers can handle. The minimum recommended input power ratings for CVP-1152 and CVP-2153 systems displayed in the Specifications Table.

Cable Selection

The quality and characteristics of the speaker cables used also greatly effect speaker performance. Always high-quality cables made with professional-grade wire and connectors that are correctly and carefully fitted. Selection of the appropriate wire gauge is especially important to system operation. A cable that is too light low-gauge will result in amplifier power being wasted due to the series resistance of the cable and in loss low-frequency performance due to degraded damping factor. The ideal gauge is determined by two factors: length of the cable and the load or impedance. For cable runs up to 50 feet (15m) with an 8-Ohm load, recommend using at least 14-gauge wire – 12-gauge is minimum for a 4-Ohm load. For runs between 50 feet (15-30m), use at least 12-gauge for 8-Ohm loads and 10-gauge for 4 Ohms. At 200 feet (60m), you use 10-gauge and 8-gauge, respectively, and so on.

Using Poles, Tripod Mounts, and Speaker Movement Due to Vibrations

The Cerwin-Vega! CVP speakers covered by this manual are designed for portable applications in which the speakers will be stacked directly on the floor, stage, a solid stable platform, mounted on a tripod stand or pole-mount. (Pole and tripod mounting only applies to the CVP-1152). The CVP Series also may be suspended using industry standard, forged M10 eye bolts. Please refer to the suspension warnings and instructions further in this document.

THESE SPEAKERS ARE HEAVY!

Please use common sense and adhere to the manufacturer's hardware ratings when placing speakers on s or poles. Never exceed the rated safety limit of a pole or speaker stand. Never place a speaker on a pol tripod that is leaning at an angle as the speaker may tip over.

Cerwin-Vega! Professional speakers can generate considerable energy. When placed on a slippery surface s as polished wood or linoleum, the speaker may move due to vibration caused by its acoustical energy outp Precautions should be taken to assure that the speaker does not fall off a stage or platform on which it i

The Cerwin-Vega! CVP-1152 speaker model includes a receptacle cup to allow mounting on tripod stands or poles. When using stands or poles, be sure to observe the following precautions:

• Check the stand specification to be certain it is designed to support the weight of the speaker.
• Observe all safety precautions specified by the stand manufacturer.
• Always verify that the stand is placed on a flat, level, and stable surface and be sure to fully extend legs of tripod type stands. Position the stand so that the legs do not present a trip hazard.
• Route cables so that performers, production crew, and audience will not trip over them pulling the spe over.
• Do not attempt to place more than one speaker on a stand designed for a single speaker.
• Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight (i.e. sandbags) on the base of the stand to improve stability.
• Unless you are confident that you can handle the weight of the speaker, ask another person to help you lift it onto the tripod stand or pole.

Moisture

Moisture can damage the speaker cone and surround and cause corrosion of electrical contacts. Avoid exposing the speakers to direct moisture. Keep speakers out of extended or intense direct sunlight. The drip suspension will prematurely dry out and finished surfaces may be degraded by long-term exposure to intense ultra-violet (UV) light.

Powering Up

To avoid damage to your speaker and other parts of your system, when you turn On your system, always turn On the power amp last! This will avoid loud, damaging pops that will annoy your audience, and blow your spe. When you power down, the amplifier should always be turned Off first to avoid the same problems.

Polarity

When using two or more speaker systems, be sure to match the polarity (+/-) of the speaker system conn to those of the amplifier. If polarities do not match, the sounds produced by the speaker will interfere with other, making it impossible to achieve a well-balanced sound field.

Hearing damage and prolonged exposure to excessive SPL

CVP Series loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause permanent hearing damage to performers, production crew, and audience members. Proper precautions should be taken to avoid prolonged exposure to SPL in excess of 85 dB.

4. SET UP AND USE OF THE CVP-2153 AND THE CVP-1152

Input Configurations / Full Range and Bi Amp Modes

The CVP Series models are equipped with both a 4-pin Speakon connector and two 1/4" phone jack input speakers provide FULL RANGE mode where one amplifier signal powers the entire speaker or BI AMP mo (Speakon only) where one amplifier signal powers the high frequency compression driver and a second amplifier powers the low frequency driver(s).

The 4-pin Speakon connectors are configured as follows:

• FULL RANGE mode: 1+ positive / 1- negative. (2+ and 2- are not used)
• BI AMP mode: 1+ LF positive / 1- negative, 2+ HF positive / 2- HF negative.

The quarter inch phone jacks are configured as follows:

- FULL RANGE mode only: Tip positive / Sleeve negative.

To change the system to Bi Amp mode follow these directions:

1. Remove the grill (twelve screws) and woofer (eight screws) NOTE: Woofer connection polarity.
2. Move the wire harness from "FULL RANGE" to "BI AMP" on the input circuit board and the crossover circuit board. Please check (Figure 1, Full Range Mode), displayed on the next page.

1. Ensure the connector is seated properly.
2. Reconnect the woofer and tighten all eight screws.
3. Reinstall the grill with all twelve screws.

To change the system back to Full Range mode see steps 1-5 above, but move the wire harness from "E to "FULL RANGE" on the input circuit board and the crossover circuit board. Please check (Figure 2, Bi A Mode), displayed on the next page.

5. CONNECTING AND DAISY CHAINING SPEAKERS

The inputs of the connectors are paralleled to the “through” connectors in both Full Range and Bi Amp method that either connector will work. The other connector can then be used to send the signal to another speaker. Refer to the following diagrams for the proper impedance values (stated in Ohms) when daisy chaining speakers. (Figure 3)

6. HIGH FREQUENCY FAST REACTION PROTECTION CIRCUIT

Your CVP speakers offer a fast reacting suppression limiter that senses input voltage and reduces potential damaging voltage levels that would otherwise reach your high frequency drivers.

7. ROTATABLE HORN

The high frequency horn in the CVP series is installed in a 60 degree horizontal and a 40 degree vertical orientation. The horn can be rotated to provide 40 degrees vertically and 60 degrees horizontally for an alternative high frequency dispersion pattern which is useful in certain install situations or when using the CVP-1152 as a floor monitor.

Remove the screws, then rotate the horn 45 degrees, and replace the screws being careful not to apply to torque pressure.

8. USING THE CVP-1152 AS A FLOOR MONITOR

The CVP-1152 can be used as a floor monitor. Typically, you will want more high frequency coverage from right across your stage or performance area. Follow the instructions earlier in this document to rotate the Note that you can even rotate the grill to orient the Cerwin-Vega! logo in the correct position! How cool is

To rotate the grill, first remove the grill screws. Pull the grill out and turn it 90 degrees. Replace the screw careful with the torque pressure applied.

9. WARNING ABOUT SUSPENDING LOUDSPEAKERS

The CVP Series uses forged M10 eye bolts.

Only use eye bolts that are professionally certified for the proper 10x load requirements.

Suspending loudspeakers is serious business! Injury or death can occur if loudspeaker systems are not suspended correctly! Read and follow these instructions carefully!

Speaker suspension must take place in accordance with instructions provided by Cerwin-Vega! and under the supervision of a licensed, professional sound/rigging engineer or structural engineer. Only use attachments, mounts, accessories, or brackets specified by Cerwin-Vega! or only specified products rated for overhead suspension. Refer all servicing to qualified personnel. Servicing is required when the apparatus has been damaged in any way.

WARNING! Before placing, installing, rigging, or suspending any speaker 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 suspension, placement, or array. Any such condition severely reduces the safety of the suspension and should be immediately corrected. Use only hardware which is rated for the loading conditions of the suspension and any possible short-term unexpected overloading. Never exceed the rating of the hardware or equipment. Consult a licensed, professional engineer when any doubt or questions arise regarding a physical equipment installation. Cerwin-Vega! is not responsible for damage or liability for improperly installed or maintained mounting and/or rigging systems.

10. SUSPENSION OF THE CVP SERIES

Remove the fly bracket screws in the fly points where you want to install M10 eye bolts. Screw in the M10 bolts being careful not to strip the fly bracket screw insert point. Do not remove fly bracket screws from a where you will not install eye bolts – insure that either an eye bolt or a fly bracket screw is installed in a bracket screw insert locations.

De-rating

Using the mounting points at an angle will de-rate the WLL (Working Load Limit) for each mounting point. Point mounted at an angle should be de-rated according to the following formula.

• WLL = cosine (angle) x 500
• Where: angle = degrees form vertical pull

500 = WLL for each CVP mounting point @ vertical pull
