Installation
This section tells you about the connections, control elements
and application possibilities of your Lehmannaudio Black CubeII/
Black Cube SEII phono amplifier.
1 | Unpacking
After unpacking the Black CubeII/Black Cube SEII check it for possible transport
damages. If you notice visible damages, you must by no means connect the
device to mains. In this case consult your dealer immediately.
Delivery includes the following components:
≠Black CubeII device
≠Power supply (Black CubeII) or
PWX power supply (Black Cube SEII)
≠Mains cable
≠User manual
≠Allen key (2 mm)
≠2 jumpers
≠Certificate of warranty
Note
We recommend keeping the entire packaging for later shipment.
That way you will avoid transport damages. Use by no means
‘foam chips’ or similar packaging material. Otherwise the device
will jolt through to the bottom of the cardboard box during
transport and can be damaged! If the original packaging is no
longer available, it’s best to use bubble wrap in which to wrap up
the device in a generous manner. Finally the whole should be put
into a solid cardboard box.
2 | Setup
Always position the Black CubeII/Black Cube SEII on a stable surface. Thanks to
the compact dimensions and low weight, you can set up the Black CubeII/Black
Cube SEII directly next to the record player.
3 | Connecting
Check whether the included mains adapter is suitable for connection to the
mains network used in your country. On the adapter, you will find informa-
tion about the specified mains voltage for the device. Now connect the Black
CubeII/Black Cube SEII to the mains network using the external power supply
and the connection on the rear of the device.
Note the safety instructions starting on page 32!

Black Cube II/Black Cube SE IIBlack Cube II/Black Cube SE II

ATTENTION!
Never connect the output of the Black CubeII/Black Cube SEII
to the phono input of another device. This could damage the
phono stage or speakers.
5+7| Input jacks (IN)
Connect the cables coming from your record player to these jacks. Here too,
please be sure to connect the cables to the correct channels.
Putting into operation
To put your Black CubeII/Black Cube SEII into operation, you
need information about your pick-up system.
Two details are important: Are we talking about an MM (moving magnet) or MC
(moving coil) system? What is the required connection resistance? As a rule, you will
find both pieces of information on the product packaging of your pick-up system.
Please ask your specialist dealer for recommended values in case of doubt. Support
for correctly configuring your Black CubeII/Black Cube SEII will be gladly provided.
Once you have the required information, please proceed as follows:
1 | Set the volume on your system to minimum or turn your amplifier off
entirely.
2 | Connect the power supply.
3 | Set the gain for your pick-up system (MM/MC) on the Black CubeII/Black
Cube SEII. The settings must be made in the same way for both channels
and are done by means of the DIP switches A and B on the bottom side
of the device. Common amplifier settings for various types of pick-ups
are found on the next page. The gain switch (respectively B1) is active on
delivery.
4 |
Set the terminating resistance on the Black CubeII/Black Cube SEII. The
setting must be identical for both channels. Use the custom impedances in-
side and the DIP switches on the bottom of the device. Further information
is found on page 44.
5 | Connect the record player to the input on the Black CubeII/Black Cube SEII.
6 | Connect the output on the Black CubeII/Black Cube SEII to a line input on
the downstream amplifier. To largely exclude line losses, the signal cables
should be kept short.

Expert notes
The Black CubeII/Black Cube SEII can be adapted to virtually
all systems available on the market. With the exception of the
DIP switches, the adjustment mechanisms are located inside
the device and should only be changed by experts. An Allen key
for opening the enclosure and jumpers for bridging the output
capacitors are supplied with the device.

1 | DC L/DC R
The MKP output capacitors are bridged with these jumpers so they are no longer
in the signal path. These jumpers are not activated at delivery.
ATTENTION!
When output capacitors are bridged, there may be DC voltage on
the outputs. Before activating these jumpers, it is therefore neces-
sary to ensure that the downstream input stage has a DC voltage
input filter since DC voltage can damage the speakers. In case of
doubt, have your system checked by the dealer first.
2 | DIP switch C on the bottom side of the device
With switch no. 1 you can set the bass cut filter behind the output stage to 27 Hz.
Switch no. 2 sets the filter to 15 Hz.
An attenuation of the low-frequency range may be useful to protect your
loudspeakers against excessive transients, particularly from warped records. If the
speakers are placed close to a wall, a low-frequency adjustment can enhance the
sound.
The Black CubeII/Black Cube SEII offers a total of 16 different filter settings
which you can select by ear. More details on the different setting options can be
found in the annex on page 138 ff.
3 | DIP switch B on the bottom side of the device
Switch no. 1 changes the gain by +10 dB and is active on delivery.
Using switches no. 2 and 3 you can set the bass cut before the output stage to 23,
30 or 47 Hz. More details on the different filter settings can be found in the annex
on page 138 ff.

Black Cube II/Black Cube SE IIBlack Cube II/Black Cube SE II

4 | DIP switch A on the bottom side of the device
With these switches you can choose between different gain settings and also
select the input impedance for MC systems. Common setting options for various
systems are available in the chart on page 42 f.
5 | R104/R204
Available custom impedance plug connections for activation with the DIP switches
for the channels (respectively no. 3). An impedance/capacity activated here is
switched in parallel to all other impedances/capacities activated by switches and
the 47 kohms/100 pF.
6 | R102/R202
These are free hardwire plug-in slots for additional impedances/capacitors with
immediate effect and no need for activation via switches. A resistor/capacitor
plugged in here will be put in parallel with all other switch-activated impedances/
capacitors and the 47 kohms/100 pF.
1 | Adjusting the pick-up arm geometry and system should always be performed by
a specialist. In case of incorrect settings, the effects range from sound problems to
one-sided and therefore premature wear of the system. Good specialist dealers have
special measuring and adjusting equipment. It is much more accurate than what may
be included with the pick-up system.
2 | On record players with a sub-chassis, the vibration behaviour should also be
optimised by an expert. Sound improvements are possible here as well.
3 | Using a decoupling mat that contributes to better mechanical separation
between the record and turntable can further improve the sound quite significantly.
4 | Special attention should also be paid to the chosen cable materials and
assembly. This applies in particular to the system cables (headshell), the cables from
the pick-up to the Black CubeII/Black Cube SEII and the cables to the downstream
pre-amplifier.
Sound optimisation tips
The Black CubeII/Black Cube SEII can only be as good as the
signal supplied by the turntable or pick-up system. Since playing
back a record consists of mechanical sampling with many impor-
tant influencing variables, we provide some sound optimisation
tips here. For high-end record players in particular, you should
consult your dealer for the required service and adjustments.
