Troubleshooting
Fault Cause Solution
LED indicator is
not lit.
The mains cable is not

The power supply is not
connected with the device.
Connect the power supply with
the device.
Input and output are not
wired correctly on the
Decade.
Check if the cables coming from
the turntable are connected to
the input and also if those going
out to the amp are connected
to the output of the Decade.
Reconnect them correctly if
necessary.
