Safety

Speaker Protection

All loudspeakers have electrical, thermal and physical limits that must be observed to prevent damage or failure. Too much power, low frequencies applied to high frequency drivers, severely clipped waveforms and DC voltage can all be fatal to cone and compression drivers. The Peavey PV® 3800 amplifier automatically protects speakers from DC voltages and subsonic signals. For more information, see the section on Protection Features. Mid- and high-frequency speakers, especially compression drivers, are highly susceptible to damage from overpowering, clipped waveforms or frequencies below their rated pass band. Be extremely careful that the low and mid bands of an electronic crossover are connected to the correct amplifiers and drivers and not accidentally connected to those for a higher frequency band. The amplifier’s clipping point is its maximum peak output power and can 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 that the amplifier never clips, use a properly adjusted external limiter (or a compressor with a ratio of 10:1 or higher) to control power output. In systems with active electronic crossovers, use one for each frequency band. The clip limiter will automatically limit the dura- tion of continuous square waveforms applied to the speakers. The amplifier will, however, allow normal musical transient bursts to pass. Some speaker systems are packaged with processors that have power limiting circuits and should not require additional external limiting.

Fuses may also be used to limit power to speaker drivers, although as current-limiting (rather than voltage-limit- ing) devices they are an imperfect solution. As the weakest links, fuses only limit once before needing replace- ment. Some poor-quality fuses have a significant series resistance that could degrade the amplifier’s damping of the speaker’s motion and may even deteriorate the system’s sound quality. If you elect to use fuses, check with the speaker manufacturer to determine the proper current rating and time lag required.

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.

Amplifier Maintenance and User Responsibility

A PV 3800 amplifier requires no routine maintenance and should never need any internal adjustment during its lifetime. Your PV 3800 amplifier is very powerful and can be potentially dangerous to loudspeakers and humans alike. It is your responsibility to read the Important Precautions section in the front of this manual and to make sure that the amplifier is installed, wired and operated properly. Many loudspeakers can be easily damaged or destroyed by overpowering, especially with the high power available from a bridged amplifier. Read the Speaker Protection section and always be aware of the speaker’s continuous and peak power

capabilities.

PV 3800 specifications

The Peavey PV 3800 is a powerful and versatile amplifier designed for professional audio applications. It is particularly popular among musicians, DJs, and sound reinforcement professionals who need reliable performance in various settings. This amplifier is known for its robust build quality and exceptional sound reproduction, making it a trusted choice in the world of live sound.

One of the standout features of the PV 3800 is its impressive power output. With 3,800 watts of peak power, this amplifier can easily drive large speaker systems, delivering clear and powerful audio even at high volumes. It provides 1,900 watts at 4 ohms in stereo mode, which ensures that it can handle demanding audio environments without distortion or loss of clarity.

Additionally, the PV 3800 is equipped with Peavey’s patented DDT speaker protection circuit. This technology helps prevent speaker damage by automatically detecting when the amplifier is being driven beyond its limits and adjusting the output accordingly. This feature is invaluable for live performances, where fluctuations in sound levels can occur, and it protects both the amplifier and the connected speakers.

Another key characteristic of the PV 3800 is its dual-channel design, which allows for multiple audio sources to be amplified simultaneously. Each channel features its own independent volume control and input options, providing flexibility for a variety of audio setups. Whether used in a simple two-speaker system or a complex multi-speaker arrangement, the PV 3800 can adapt to the specific needs of the user.

The amplifier's rear panel includes extensive connectivity options, such as XLR and 1/4-inch inputs, making it compatible with a wide range of audio equipment. Additionally, the PV 3800 features a fan-cooled design that helps maintain optimal operating temperatures during long performances, ensuring reliability and longevity.

In terms of size, the PV 3800 is notably portable, allowing for easy transport between gigs. Its durable construction means it can withstand the rigors of touring and live use, making it an excellent investment for professionals who need gear that can keep up with their demanding schedules.

In summary, the Peavey PV 3800 stands out for its powerful performance, innovative technologies, and user-friendly features. With its ability to deliver high-quality audio in a reliable and robust package, it continues to be a popular choice among audio professionals looking for a dependable amplifier.
