Speaker damage
The DA-2800 amplifier is among the most powerful professional amplifiers available and therefore, if
used improperly, is capable of damaging Procella loudspeakers. Reduce power immediately if you hear
any clipping distortion or other distress such as a woofer "bottoming out" - harsh pops or cracking
distortion that indicate that the speaker voice coil or diaphragm is striking the magnet assembly.
Speaker output shock hazard
The DA-2800 amplifier is capable of producing hazardous output voltages. To avoid electrical
shock, do not touch any exposed speaker wiring while the amplifier is operating.
This manual contains important information on the proper and safe operation of your DA-2800
amplifier. Please read it carefully before operating your amplifier. If you have any questions,
contact your Procella dealer or distributor.
