AYRE AX-5 - Manual (Page 33)

DC Offset
The Ayre AX-5 incorporates a circuit to detect the
presence of DC at the output terminals which could
be harmful to the loudspeaker. In this situation, the
warning LED in the display will glow red, the input
will be muted, the bias will be removed from the
output stage, and the amplifier will not operate.
The input selector characters will change to read
“DC” when excessive DC offset is present.
If the DC offset was coming from a faulty source
component, when the amplifier input mutes the red
warning LED will go out, the green LED will light
as the unit reverts to the low-operating current
mode, but the “
DC ” message will remain so that
cause of the error is known.
Disconnect the source component that caused the
error from your system. Then press the right-hand
front-panel button to return the unit to the normal
operate mode and select a different source
component. If the system operates properly in this
case, take the faulty source component to an
authorized dealer or service center.
If there are any unusual noises coming
from the loudspeaker, turn the
rear-panel AC power switch to “Off/0”
immediately. Please return the unit to
your authorized dealer or service
center.
