Adaption of input impedance
You can change input impedance (resistive loading) and gain by using the onboard DIP-switches for each channel separately.
These switches are accessible from the bottom of the unit. Input capacitance is always 100pF.
You may change the setting of the switches withthe Black Cube SE II connected to mains voltage and even to your stereo
system however in that case please first turn your volume knob to the minimum position because loud pops could occur during
switching.

The Black Cube SE II is highly flexible and also offers an insert point for inserting a resistor to accommodate cartridges which
require special loading to be activated by the switch and one additional hardwire slot for each channel for permanant
installation with direct effectivity. In case you own a cartridge that needs special load adaption please consult your dealer to
have him install this special impedance. High quality metal film resistors are recommended for sonic reasons. In case you want
to install a custom impedance yourself please proceed as follows:
• Disconnect the power from the Black Cube SE II's power supply..
• Place the Black Cube SE II on a clean smooth surface of sufficient size and without any sharp edges that could harm
the unit.
• Carefully unscrew the six screws of the audio board‘s case with the tool included.
• After removing the top you can now insert your custom input load for each channel. Do not use any tools
that could damage the electronic circuit. Please use only high quality metal film resistors.
• The custom load can now be activated the DIP switches that are accessible from the outside at the bottom of the
unit near the input RCA connectors. To activate your custom load you have to set the switches no. 3 to the “on”
position.
If all impedance switches of DIP-switch nr. 1 are in the OFF-position the input impedance is 47kOhms which is suitable for most
MM cartridges. The gain switch can be activated deparately so that MC/47k becomes an easy option. This is recommended for
some MC cartridges. Please refer to your cartridge‘s information sheet for the recommended load. If you only know the
internal impedance of your cartridge you can use the rule that the load imnpedance should not be less then 10x the internal
impedance of the cartridge.
Both channel settings and impedances have to be identical!
Important: The impedance switches connect the selected impedance in parallel to the 47k Ohms resistor. So the highest
custom load that can be realized is always lower than 47k Ohms. Install these resistors only if you know what you are doing.
Otherwise please consult your dealer.
