5. Summary of Operations
• Connecting and starting-up:
Check to ensure that the mains voltage (110 V in the
USA and Japan, 230 V in Europe) at your location
corresponds to what is permitted for operating your
BASSCUBE. You will find the necessary information
on the rear under “Dest.” (country of destination)
and “AC-voltage”. The voltage is factory set appro-
priately for the country to which the set is delivered.
However, you can switch the voltage between 110
and 230 volts if you wish to operate the BASSCUBE
in another part of the world. For this purpose, re-
move the voltage switch element from the Power
on/off module and rotate the inset until the desired
voltage shows in the inspection window. Then re-
turn the element (115 volts on the indicator corre-
spond to 110 volts.
Before switching the amp on, the “Master” and “Re-
turn” controls should be in the zero position (as far
left as they will go) and all other controls in middle
position. Then make all necessary cable connections
(mains, instrument and/or microphone). Now you
can switch on your BASSCUBE with the “Power”-
switch on the rear of the amp. The green power in-
dicator shows that the amp in operational.
• Level control:
You can use the “Gain”-control to match the vari-
ous pick-up systems and signal sources to the BASS-
CUBE. The “Clip”-indicator shows when the input-
signal is too high. You should then reduce the gain-
control or the volume-control in your guitar or oth-
er source to ensure distortionfree reproduction. Then
set the desired overall-volume with the “Master”-
control; “HF-Vol.” is the control for the share for the
high-frequency power amplifier.

• Tone control:
The three-band tone control of your BASSCUBE is
technically of a completely parametric design; how-
ever, only the mid-band can be user adjusted in fre-
quency and level. We hope that we have chosen the
filters so that you will be provided with a versatile
and universal amplifier too that can come to terms
with the variety of basses and voices. Please tell us
if we are right. However, we are of the opinion that
more is needed in order to make an instrument sound
balanced. For one part, the “Colour”-switches on
channels 1 and 2 make it possible to turn the tone-
brighter and more transparent. On the other hand,
the “Harmonics”-control makes it possible to mix
generated overtones into the bass signal. We are
confident that harmonics, colour and variation of
the ratio of treble to bass will enable you to estab-
lish a basic sound that you can then adjust with the
tone-controls as needed. You should remember here,
too, that more can be less. Extreme treble-accentu-
ation (unbalanced reproduction characteristics par-
ticularly in combination with active bass-electron-
ics) will also amplify hiss from stage to stage.
• Three channels – why?
Channel 1 and 2 are intended to be the main in-
strumental channels. Several input stages, colour,
harmonics and three-band tone-control are equal-
ly available for two instruments or two signal-sources
on one instrument. Channel 3 is intended to be the
adress or vocals channel. Each channel has special
attributes, but the following features are also dou-
bly available: “Line”, “Piezo”, “Mic”, “Voice”,
“Colour”, “Harmonics” and “Three-band tone-con-
trol”.
