Sound Setting
When the power is switched ON, all control knobs function as labeled
on the panel and described below. All lamps on the display above the
control knobs and switches are unlit.
Rotate the SOUND TYPE knob to select a sound type, then use the
Tone Control knobs to shape the sound. Before selecting a sound type,
first set the GAIN through TREBLE control knobs to their center posi-
tions then try out the different Sound Types.
Also, the COMP knob is used to adjust the compressor’s compression
ratio. The compressor automatically balances the differences between
loud and soft levels when playing. Rotate the knob to the right to in-
crease the amount of compression.
q
q INPUT LEVEL: Sets the Input Level
w SOUND TYPE: Selects the Sound Type (11 types)
FLAT ............A clean tone with all frequencies set flat. This setting also
works well with an upright bass or an electric-acoustic bass.
TUBE...........A clear and warm tube type sound. This setting also works
well with an upright bass or an electric-acoustic bass.
SOLID .........A fat solid-state type sound
R & B ...........A fat R & B type sound
VINTAGE .....A vintage tone with warm mid frequencies
MODERN ....A modern sound with rich low-end and bright high-end
CLASSIC .....Rock bass sound
HEAVY ........A heavier sound than the CLASSIC setting
DRIVE .........Overdrive bass sound
DIST ............Distortion bass sound
FUZZ ...........Fuzz bass sound
e COMP: Compression Ratio (1.0 to ∞, 16 steps)
This adjusts the compressor’s compression ratio and output levels simul-
taneously.
As the value increases, so does the amount of compression applied to
signals that exceed the threshold level (→ pg. 14).
r GAIN: Pre-Amp Gain (0 to 10, 0.1 step)
t MASTER: Master Volume (0 to 10, 0.1 step)
y BASS: Bass Frequency (-15dB to +15dB, 0.2dB step)
u LOW MID: Low Mid Frequency (-15dB to +15dB, 0.2dB step)
i MIDDLE: Middle Frequency (-15dB to +15dB, 0.2dB step)
o HIGH MID: High mid Frequency (-15dB to +15dB, 0.2dB step)
!0 TREBLE: Treble Frequency (-15dB to +15dB, 0.2dB step)
!1 OUTPUT: Sets the output level
Getting sound output
1 First, make sure that the POWER switch is switched OFF, then
connect your bass to the INPUT Jack on the front panel.
2 Rotate the OUTPUT knob fully to the left and then switch the
POWER switch ON.
To protect the speakers, make sure that the
OUTPUT knob is set to “0” whenever switch-
ing the POWER switch ON or OFF.
Operating Instructions
w e r t y u i o !0 !1
3 First, set the INPUT LEVEL knob to its 12 O’clock position, then
while playing the bass, gradually increase the GAIN, MASTER,
and OUTPUT knobs to adjust the sound.
4 Once the system is producing sound, set the input level as
described in the “Adjusting the Input Level” section below.
Set the knob so that the red
indicator does not light.
Adjusting the Input Level
The INPUT LEVEL control optimizes the signal received from the bass
for use with the amplifier, to produce wide dynamic range and rich tone.
A poorly adjusted level results in noise, feedback, a cutup sound, etc.
* Since output levels vary from instrument to instrument, you will need to
readjust the input level to match the instrument’s output level whenever
you change instruments.
1 Rotate the volume control on your bass to its maximum level
and play loudly while rotating the INPUT LEVEL knob.
An ideal level is attained when the green indicator is lit.
2 Continue to rotate the INPUT LEVEL knob to the right making
sure the red indicator does not light. As long as the red indica-
tor does not light, rotate the knob fully to the right.
HINT Using the OUTPUT and MASTER Controls
Both knobs can be used to control the overall volume however, the
MASTER knob is the preamplifier’s master volume and its setting is
saved in memory. The OUTPUT knob is the power amplifier’s output
volume and its setting is not saved in memory. Use the MASTER knob
to set individual volume settings of patches saved to memory, and use
the OUTPUT knob to set the output volume level produced by the speak-
ers.
