Plug the power supply into the
outlet.
Connect the power supply to
the device.
Check whether the cables com-
ing from the record player are
connected to the input and the
cables leading to the amplifier
are connected to the output
of the Black Cube Statement,
and connect them correctly if
applicable.
Select the correct input channel.
Check the position of both DIP
switches and/or gain Jumpers.
Make sure that the settings are
the same for both channels.

Check the connecting cable
for bad contacts, loose plug
connections and defects, and
replace it if required. Possibili-
ties: System cable (head shell),
pick-up arm cable from the
record player to the Black Cube
Statement and line cable from
the Black Cube Statement to
the downstream input.
Resolve by connecting to vari-
ous line inputs.
Check the connecting cables
and swap the channels here if
applicable. Possibilities: System
cable (head shell), pick-up arm
cable from the record player to
the Black Cube Statement and
line cable from the Black Cube
Statement to the downstream
input.
Increase the amplification
factor according to this user
manual using the DIP switches
under the Black Cube State-
ment and/or activate the high
gain Jumper.
Adjust the input resistance so
it is higher than the system
impedance of the pick-up by at
least a factor of 10.
