AYRE TK-8150 - Manual (Page 29)

In Case of
Trouble
Should the Ayre KX-R preamplifier ever fail to operate
properly, please check the following:
Symptom: Mechanical noise when changing
the volume level or selected input.
This is a normal consequence of the precision stepping motors
moving the solid-silver contact rotary switches.
Symptom: An audible “whirring” sound
when selecting or deselecting an input
connected to a surround-sound processor.
This is a normal consequence of the precision stepping motors
moving the solid-silver contact rotary switches at high speed to
reach the unity-gain setting or revert to the normal gain
setting.
Symptom: Slight audible hum from the
loudspeakers when listening at high levels.
This is a normal consequence of the ultra-high input impedance
picking up hum from an input that is activated (named), but
not connected to a source component. Deactivating the input or
connecting a source component will eliminate any hum pickup.
Symptom: Remote control not working. Check the condition of the batteries (4 x AAA) located in the
remote control.
Symptom: Standby indicator LED not
illuminated.
1) Be sure that the unit is connected to a working AC outlet.
2) Check the AC line fuse on the rear panel of the unit.
