current phase angle or the reactance of the loudspeakers
which the amplifier is driving. Sometimes, when the
amplifier is in use, the LEDs may occasionally flicker
during high volume listening, particularly if you are driving
low impedances. This flickering is no cause for concern.
The LEDs are simply warning you that the amplifier is
approaching its maximum power output into the particular
loudspeakers you are using. If, however, the Distortion
Alert LEDs glow brightly or are illuminated most of the
time during playback, you are over driving the amplifier
and should turn down your volume control to reduce
the listening level, otherwise it may cause the Thermal
Protection to be activated or, in extreme cases, damage
your loudspeakers.
