WARNING!

This amplifier is intended to drive passive loudspeakers. These may produce sound pressure 
levels which can be harmful for humans and animals when used incorrectly and/or without 
protection. Possible permanent hearing loss may occur when humans or animals are exposed to
high sound pressure levels for anextended period of time.
