Need help?Do you have a question about the Peavey PV 3800 and is the answer not in the manual?
OSHA permissible noise exposure limits for hearing protection and potential loss.
Channels operate independently, controlled by individual attenuators.
Single input drives both channels, input attenuators active.
Combines both channels for single-channel monaural output, use caution.
Reduces gain to prevent clipping and protect speakers from square waves.
Outputs disconnected for ~6 seconds at power-up for stabilization.
Adjusts gain to safe level for overstressed loads, superior to conventional limiting.
Gradually raises signal after power-up, prevents bursts, extends contact life.
Shuts down channel if heat sink reaches 75°C to prevent overheating.
LFC circuit senses shorts, attenuates signal, eventually disconnects load.
Opens output relay to prevent speaker damage from DC voltage or subsonic frequencies.
Explains speaker limits and amplifier's protection against damage from power/clipping.
