1.0 CONNECTIONS AND CONTROLS
frequencies are boosted or cut.
ACTIVE INPUT: Use this jack to connect basses with high
output levels, notably active instruments or basses
equipped with humbucking pickups.
TREBLE: Use this control to adjust the high end, i.e. dial in overtones or add a cutting edge to the tone. To give your
BassForce a warmer tone, we placed this pot in the circuit
right after the input stage, so it also has some influence over
preamp saturation.
PASSIVE INPUT: Connect traditional basses with passive pickups
and tone controls to this jack.
EQ MATRIX: Use this rotary knob to dial in several different basic
sounds.
EQ MATRIX ON: Activates the basic sound selected with the
rotary knob. When the EQ Matrix is switched on, the standard
EQ section of the BassForce remains active.
GAIN: Controls the input sensitivity of the BassForce preamp.
Use it to dial in a level suitable for the output level
of the bass you have connected. Higher gain settings
produce punchier tone well-suited to rock styles.
SATURATION LED: Indicates that the BassForce preamp is
being mildly overdriven. For ultra-clean sounds, set the
GAIN knob so that this LED does not illuminate.
BASS: This active voicing control defines the bottom end.
At a setting of 12 o’clock, the signal remains completely unaffected.
MID FREQ: Lets you select which mid-range frequencies are
affected. The MID LEVEL knob determines the intensity of the
adjustment.
MID LEVEL: Determines to what extent the mid-range
MASTER: Controls the stage volume of the BassForce.
It does not, however, influence the output level
of the LINE OUT jack. At higher volumes, the DynaClip
circuit kicks in and the tone of the amp will produce
a more "growling" tone.
PHONES: Connect headphones to this jack. The BassForce
speaker output circuit is automatically muted when this jack is
used.
MAINS: AC power switch.
REAR PANEL
MAINS SOCKET: Connect the Euro-norm mains cable to this
socket. The fuse bracket is integrated in the socket; ensure you
use specified replacement fuses only!
SPEAKERS: Use this output to connect external speakers/cabinets. You have two options for connecting additional cabinets
to the BassForce XXL. For one, the amp is equipped with a serial speaker circuit that lets you do just that—drive the internal
speaker in series with a connected external speaker. Although
this increases resistance and thus decreases power output, the
surface area of the speakers is enlarged several times over. For
the other

option, the amp is equipped with an external speaker jack
that deactivates the internal speaker, letting you connect a
set of speakers with a total load no lower than 4 ohms.
LINE OUT: Balanced output of the BassForce preamp. Connect
it to a mixer or power amp. This output is
post-EQ section—in other words, the tone knobs
influence this signal; the MASTER volume knob,
however, does not.
FX RETURN: Connect the output of your effects device
to this jack.

3.0 OPERATING THE BASSFORCE XXL
3.1 THE EQ MATRIX
The BassForce series is equipped with the EQ MATRIX,
a feature that lets you activate four different settings of
a 31-band graphic equalizer at the flick of a switch.
Renowned professional players helped define these
sounds and we painstakingly tuned them to give
you instant tone at your fingertips.
FX SEND: Connect this output to the input of your
effects device.
BASSFORCE XXL SOUND I:
FOOTSWITCH: Input jack for a standard footswitch. Note: The
front panel switch is deactivated when you plug a footswitch
into this jack.
BASSFORCE XXL SOUND II:
Warm bottom end, easy on the mids, shimmering highs,
suitable for all playing styles.
Highly defined and precise, lets you and your audience hear
every nuance of your slap technique.
BASSFORCE XXL SOUND III:
Fretless bass tone, also ideal for ballads, particularly when the
preamp is ever so slightly saturated.
BASSFORCE XXL SOUND IV:
Heavy stuff for serious headbanging; regardless whether you
use a pick or your fingers, this is a great sound for
rock bass.

best results when you do select another sound during your set.

The SATURATION LED will illuminate as the amp goes from a
clean sound to a tube-like mellow overdriven tone. If the LED
lights up in response to every note you play, the preamp of the
BassForce is thoroughly saturated. In this case, turn the GAIN or
TREBLE knob down.
2. Mid-range Fine-tuning:
You'll find the following procedure particularly effective:
• Turn the MID LEVEL control all the way up so you can clearly
hear the results when you tune the frequency band.
• Dial in the desired center frequency via the MID FREQ knob.
You will hear a wah-wah effect when turning this knob. At
