The information provided
on this page is calculated

channels to rated output.
Other parameters used in
calculation include a con-
servative idle draw esti-
mate of 90 Watts and a
conservativeestimationof
efficiency at 85%.Informa-

duced. Actual perfor-
mancewillvarydepending
on environment, program
material, load, signal, and
AC mains voltage and fre-
quency. Figures calcu-
lated for various program
material use estimated
duty cycles, taking into
account the typical crest
factor for each type of
source material. Values of
calculated current draw
are intended to represent
averagedrawcorrespond-
ing to the thermal breaker
requirements that should
be met to handle the am-
plifier as a load on theAC
mains. Peak current draw
withdynamic program ma-
terial may be significantly
higher. Thermal informa-
tion is provided to assist
with calculating air condi-
tioning needs. The above
