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
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

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.
