GAIN adjusts the input signal level for the EBS
MicroBass 3. An optimum level is when the
peak
led starts flashing when playing hard on your
instrument. A correctly set gain is vital for the
signal processing to work properly.
CHARACTER FILTER
When active, bass and
treble are boosted while the
midrange gain will be slightly
dropped, known as a smiley
EQ curve. This way the sound
will be preshaped before the
final adjustments using the
other features of the preamp.
BRIGHT is an advanced high pass filter that
produces a bright high-treble timbre, without
adding any noise. This switch gives a gain of
10 dB at 10kHz.
BASS is a 'shelving' type
12dB/oct slope phase
compensated bass filter
with a wide gain range.
MID. These two knobs works
in conjunction. Use the right
control to pick a frequency.
Use the left control to boost
or cut the gain in the range
of the chosen frequency.
Note: When the left control
is set to
Notch
, you can use
the right control to find and
erase a precise frequency that
causes unwanted feedback
(a common issue with upright
basses in larger rooms).
TREBLE is a shelving type filter controlling the
higher mids and treble registers, giving presence
and ambiance to the sound.
BYPASS. This switch
bypasses ALL filters in the
clean channel and sets a
flat frequency response.
COMP. This control knob sets the
compression ratio, i.e. The signal strength
relation between the input and output; the
higher the ratio the more compression. The
LED indicates when the compressor responds
during play. It is a low noise compressor/
limiter that will tightening up the sound and
prevent the preamp from saturating at peaks
when approaching the headroom limit.
DRIVE controls the amount of gain in the tube
emulation stages (engines), and provides an
extra gain all the way up to 40 dB. This control
also compresses the sound when turning up level
up to maximum, producing pure limitation.
TYPE sets the drive tone character to THIN or
DEEP (neutral in the between position). The
deep position compensates for low-frequency
loss at very high gain.
GAIN selects between a low- and high-gain drive engine.
TONE shapes the tone range of the drive engine.
Flat setting when turned all the way up.
MID is a peaking filter for the drive
channel. The two knobs works in
conjunction. Pick your frequency with
the right control, and boost or cut with
the left control in the chosen range.
BLEND sets the mix level between the
clean
channel
and
drive channel
when the drive
channel is active. To jump between the
Clean
and
Drive
channels, set this knob to the max
position and set the Serial switch to
Off
.
MUTE FOOT SWITCH
. Mutes the balanced
outputs and the master output.
Fx Send is not affected by this function.
The Mute switch also enables the built-in tuner
for silent tuning.*
DRIVE FOOT SWITCH
- Engages the drive
channel. The clean channel is always active,
but if the BLEND control is turned all the way
up, in parallel mode, this switch will make the
sound jump from the clean channel to the drive
channel when activated.
MASTER controls the volume on the Output jack.
The balanced outputs (XLR) are not affected by
the setting of this knob.
LEVEL sets the output volume for
the Drive channel.
