INPUTS: Normal and High inputs are provided for connection of bass guitars. High output
basses, either Active or Passive should be connected via the High socket. Low output basses
should be connected using the normal input. High output basses may also be placed in the
Normal input if pre-amp overloading is desired.
GAIN: This control is used to set the level of gain present in the pre-amp. The higher the level
of gain, the more the signal will clip producing distortion. The GAIN control should be used in
conjunction with the VOLUME control (9) to produce the desired signal characteristics.
COMPRESSOR SWITCH: Engages and disengages the on-board compressor. This
compresses the input-signal giving a punchier sound. In association with the compressor are
two LED’s, one indicating that the compressor is engaged and one indicating the compressor
is active. It is possible to have the compressor engaged but it only be active during certain
periods of playing - typically the most dynamic sections.
ENHANCE: provides an increased definition at the low-end of the frequency spectrum giving
you a tighter, punchier sound. The ENHANCE control does this by providing a dip in the
frequency-response of the amplifier at approximately 200hz. This dip eliminates some of the
secondary-harmonics of the important low-frequencies around 40-80 Hz producing a thicker
sound. Turning the control through to its maximum has the effect of boosting both the low and
high-frequency content of the signal whilst not effecting the mids.
BASS: Controls the low-frequency response of the pre-amplifier
GRAPHIC EQ: The 7-band onboard GRAPHIC-EQ allows extensive tonal-shaping to be
achieved. With the sliders along the centerline the GRAPHIC-EQ will exert a flat signal-
response; it is at this point that individual frequency-bands can be cut or boosted. Moving
the slider beneath the centerline will incur a frequency-cut; conversely, pushing the slider
above the centerline facilitates frequency-boost. As a general rule, avoid extreme settings of
the sliders: try to set the GRAPHIC with as little cut or boost as possible.
