CAUTION:Thereistheriskofdamagetotheloudspeakers,ifClipLimitersaredeactivated. Youshouldnot
deactivateClipLimitersunlesstheirfunctionistakenoverbyexternaldevices,suchasdigitalsystemcontrollers.
Insuchcasesitismandatory,toproperlyadjustparametersintheexternaldevice
