user responsibility

Your CD Series amplifier is very powerful and can be potentially dangerous to loud- speakers and operators alike. It is your responsibility to read important precautions (see the inside-front cover) and make sure that the amplifier is installed, wired, and operated properly as instructed in this manual.

Many loudspeakers can be easily damaged or destroyed by overpowering, especially with the high power available from a bridged amplifier. Always be aware of the speak- er’s continuous and peak power capabilities. Crest Audio is not responsible for damage to loudspeakers for any reason.

speaker protection

All loudspeakers have electrical, thermal and physical limits which must be observed to pre- vent damage or failure.Cone or compression drivers can be damaged (sometimes to the point of failure) from excessive power, low frequencies applied to high frequency drivers, severely clipped wave forms, and DC voltage. All CD Series amplifiers automatically protect speakers from DC voltages and subsonic signals.

see—TourClass protection

Mid- and high-frequency transducers—compression drivers in particular—are highly suscep- tible to damage from overpowering,clipped wave forms,or frequencies below their rated pass band.When using an electronic crossover,make absolutely certain that the low and mid bands are connected to the correct amplifiers and drivers—and not accidentally connected to those for a higher or lower frequency band.

The amplifier’s clipping point is its maximum peak output power. At maximum peak output power, Crest Audio CD Series amplifiers will deliver more power than many speakers can safely handle. Be sure the peak power capability of the amplifier is not excessive for your speaker system.To ensure that the speakers never receive excessive power, and to prevent amplifier clipping,use a properly adjusted external limiter (or a compressor with a ratio of 10:1 or higher) to control power output. Use one compressor/limiter for each frequency band in systems with active electronic crossovers.

The ACL clip limiting circuit will automatically limit the duration of squared-off, continuous wave forms applied to the speakers.The amplifier will,however,allow normal musical transient bursts to pass. Of course, when the amplifier does clip, it is operating at its maximum output power.Note that some speaker systems are packaged with proprietary“processors” that have power limiting circuits and therefore should not require additional limiting. Do not drive any low-frequency speaker enclosure with frequencies lower than its own tuned frequency; the reduced acoustical damping could cause a ported speaker to bottom out even at moderate power.Consult the speaker system specifications to determine its frequency limits,and employ a roll-off filter if necessary.

recommended speaker cabling

The wire gauge charts will assist you in determining the optimum copper wire gauge for your speaker cables.Remember that the speaker cable resistance robs amplifier power in two ways: through power lost directly to resistance (often referred to as I2R loss),and through increased total load resistance, which decreases the amount of power available from the amplifier. Appendix C gives cable length figures in feet/AWG wire gauges and in metric values.

CD Series specifications

Peavey CD Series loudspeakers are renowned for their robust design, durability, and high-performance sound, making them ideal for a wide range of applications, including live performances, installations, and mobile sound reinforcement. This series is characterized by its versatile range of passive and powered models that cater to the needs of both professional musicians and audio engineers.

One of the main features of the Peavey CD Series is its exceptional sound quality, achieved through advanced driver technology and precise engineering. The series employs high-performance woofers and tweeters, ensuring a balanced audio reproduction across a wide frequency range. This clarity makes the CD Series particularly attractive for those seeking accurate sound for live music, speeches, or other audio playback.

The construction of the CD Series cabinets is another noteworthy characteristic. Made from high-quality plywood, these cabinets are designed for durability and resilience. The finish is carefully applied to protect against wear and tear, ensuring that the speakers can withstand the rigors of touring and heavy use. The speaker enclosures are also designed to minimize resonance and distortion, further enhancing the sound quality.

The Peavey CD Series incorporates advanced technologies, including the patented Peavey Waveguide technology, which provides a controlled dispersion of sound across the listening area. This feature allows for consistent sound coverage, making the speakers effective for larger venues where audience members are spread out. The result is a more immersive listening experience, regardless of the listener's position.

Additionally, the series includes models with built-in power amplification, eliminating the need for external amplifier setups. These powered speakers often feature integrated DSP (Digital Signal Processing), allowing users to tailor the audio output to suit specific environments or preferences. This level of customization makes the CD Series an appealing choice for those who prioritize versatility in their audio setups.

Overall, the Peavey CD Series represents a fusion of innovation and practicality. With outstanding sound quality, rugged build, and user-friendly features, it serves as a reliable choice for musicians, DJs, and audio professionals alike, offering a seamless combination of performance and durability to meet the demands of any sound reinforcement scenario. Whether for a small venue or a large event, the Peavey CD Series continues to be a favored option in the world of professional audio.
