23 OPERATION
MODE
Press CLASS A, CLASS AB
or AUTO to put the
amplifier into the corresponding operating
mode.
The display will show yo
ur selection. In AUTO
mode the built-
in microcomputer will
automatically set the most suitable mode.
Class A mode uses a higher nominal
quiescent current through the output
stage, which in turn produces more heat
dissipation. The output transistors heat
the cooling sink, and the temperature is
measured by a sensor, feeding the
information back to the output stage, thus
regulating the bias.
The regulation takes a few minutes before
it becomes completely stable. During this
time high listening volumes should be
avoided.
