1.0 CONNECTIONS AND CONTROLS
ACTIVE INPUT:
Use this jack to connect basses with high output
levels, notably active instruments or basses equipped with hum-
bucking pickups.
PASSIVE INPUT:
Connect standard basses with passive pickups
and tone controls to this jack.
EQ MATRIX:
Use this rotary knob to dial in several different basic
sounds.
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-sui-
ted to rock styles.
BASS:
This active voicing control defines the bottom end. At a set-
ting of 12 o’clock, the signal remains completely unaffected.
MID:
Determines to what extent the mid-range frequencies are
boosted or cut.
TREBLE:
Use this control to adjust the high end, i.e. dial in overto-
nes 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.
MASTER:
Controls the stage volume of the BassForce. It does not,
however, influence the output level of the LINE OUT jack. When
you crank this knob, be sure to keep on eye on the POWER AMP
CLIP LED!
MAINS:
AC power switch.

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!
PHONES:
Connect headphones to this jack. The BassForce spea-
ker output circuit is automatically muted when this jack
is used.
SPEAKERS:
Use this output to connect external speakers/cabinets.
You have two options for connecting additional cabinets to the
BassForce XL. 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 deac-
tivates the internal speaker, letting you connect a set of speakers
with a total load no lower than 4 ohms.
LINE OUT:
Output of the BassForce preamp. Connect it to a mixer
or power amp. This output is post-voicing section—in other words,
the tone knobs influence this signal; the MASTER volume knob,
however, does not.
