Signal on one
channel only.
One connection lead
has a loose contact, is
not well plugged in or
defective.
Check the connection leads
for slack joints, loose pushfits
or defects and, if necessary,
replace them. Potential causes:
system cable (headshell),
tonearm cable from turntable
to Black Cube/Black Cube SE
and line cable from Black Cube/
Black Cube SE to the following
input.
The subsequent input
stage is defective.
Check by connecting to differ-
ent line inputs.
Left and right
channels are
reversed.
The channels were re-
versed in the connection
lead.
Check the connection leads and
swap the channels here, if nec-
essary. Potential causes: system
cable (headshell), tonearm cable
from turntable to Black Cube/
Black Cube SE and line cable
from Black Cube/Black Cube SE
to the following input.
Signal level is too
low.
Non-optimal matching
between pickup cartridge
and Black Cube/Black
Cube SE.
Increase the gain factor ac-
cording to this user manual
by means of the DIP switches
located on the bottom side
of the Black Cube/Black Cube
SE and/or enable the gain
jumpers.
The selected input
impedance on the Black
Cube/Black Cube SE is
too low.
Select a resistance value for the
input impedance which is at
least 10 times greater than the
pickup’s system impedance.

Input and output are
not wired correctly on
the Black Cube/Black
Cube SE.
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 Black
Cube/Black Cube SE. Reconnect
them correctly if necessary.
A wrong input channel
has been selected on the
following amplifier.
Select the appropriate input
channel.

The DIP switches are
unevenly set or there
is only one gain jumper
plugged in.
Check the positions of both
DIP switches or gain jumpers.
Make sure that the settings are
equal on both channels.
