Michi X3 Stereo Integrated Amplifier
Troubleshooting
Most difficulties in audio systems are the result of incorrect connections, or
improper control settings. If you encounter problems, isolate the area of the
difficulty, check the control settings, determine the cause of the fault and
make the necessary changes. If you are unable to get sound from the amplifier,
refer to the suggestions for the following conditions:
Power Indicator Is Not Illuminated
The front power indication will be illuminated anytime the unit is connected to
AC power and the rear power switch is set to the ON position. The indication
will be RED for standby mode and WHITE in normal operation. If the indication
is not illuminated, test the power outlet with another electrical device, such
as a lamp. Be sure the power outlet being used is not controlled by a switch
that has been turned off. And check all AC power including the rear power
switch to ensure the unit is receiving power.
Fuse Replacement
If another electrical device works when plugged into the power outlet, but
the Power Indicator still will not illuminate when the amplifier is plugged into
the outlet, it indicates that the internal power fuse may have blown. If you
believe this has happened, contact your authorized Michi dealer to get the
fuse replaced.
No Sound
Check the signal source to see if it is functioning properly. Make sure the cables
from the signal source to the amplifier inputs are connected properly. Check
the wiring between the amplifier and the speakers.
Cannot Connect via Bluetooth
If you cannot pair your Bluetooth enabled device to the amplifier, delete the
memory of the previous connection on your device. On your device this is
often listed as “Forget this Device”. Then try to make the connection again.
