A. INPUT - Plug your bass in here.
B. PASSIVE/ACTIVE - Selects pickup type (sensitivity):
PASSIVE - normal (full input sensitivity)
ACTIVE - pre–amplified (low input sensitivity)
C. GAIN - Adjusts the preamp signal level. Use together with
MASTER VOLUME {L} to set the overall amplifier
loudness. Watch the
PRE AMP
LEDs to determine the
optimal GAIN setting:
PRE AMP CLIP - Indicates preamp clipping
(distortion). Occasional flashing is normal at peak playing
intensities – reduce GAIN if unwanted distortion is heard
while this LED is on.
PRE AMP SIGNAL - Indicates the presense of
sufficient signal strength. Constant illumination is normal
at moderate playing intensities – increase GAIN and/or
your instrument volume if this LED is off or only flashing.
D. ROOM BALANCE - Rotate clockwise for treble emphasis
to compensate for soft acoustic surfaces (carpet/drapes).
Rotate counter–clockwise for bass emphasis to
compensate for hard acoustic surfaces (cement/tile).
E. ENHANCE - Boosts low and high frequencies.
OFF - Useful for finger–style bass playing
ON - Useful for slap–style/deep–tone bass playing
F. BASS/TREBLE - Adjusts tone in low/high frequency
bands respectively.
G. SEMI-PARAMETRIC EQUALIZER - Adjusts
tone in three variable frequency bands. Each
FREQ
knob selects the frequency range that
the corresponding
LEVEL
knob adjusts.
NOTE: The EQ has no effect when all
LEVEL
knobs are set to “0.”
H. EQ GAIN - Adjusts the signal level of the semi-parametric
equalizer circuit (when
EQ ON/OFF is in). Useful for
setting a balance between EQ on and off volume levels.
I.
EQ ON/OFF - Switches the semi-parametric equalizer
on/off as indicated by the LED.
J. COMPRESSOR - Compresses the dynamic range of the
signal to smooth volume peaks and increase sustain.
Rotate fully counter-clockwise to disable the compressor.
K. MUTE - Disables all amplifier outputs except for TUNER
OUT. LED flashes when MUTE is active.
L. MASTER VOLUME - Adjusts overall amplifier loudness in
conjunction with GAIN {C}. Watch the
PWR AMP
LED to
determine the optimal MASTER VOLUME setting.
PWR AMP CLIP - Indicates power amp clipping
(distortion). Occasional flashing is normal at peak playing
intensities. Reduce MASTER VOLUME if unwanted
distortion is heard while this LED is on.
M. POWER - Switches the unit on/off as indicated by the LED.
