Connections And Controls; Rear Panel - Hughes & Kettner BassForce XXL Manual

1.0 CONNECTIONS AND CONTROLS

ACTIVE INPUT: Use this jack to connect basses with high
output levels, notably active instruments or basses
equipped with humbucking pickups.
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 unaf-
fected.
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
frequencies are boosted or cut.
TREBLE: Use this control to adjust the high end, i.e. dial in over-
tones 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. 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.

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/cabi-
nets. You have two options for connecting additional cabinets
to the BassForce XXL. For one, the amp is equipped with a seri-
al 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
