INTRODUCTION • GETTING STARTED TECHNICAL SPECIFICATIONS
The EBS Session30 is a solid-state
amplifier combo, extremely easy to dialin and performs extremely well in all
styles and situations. The sound is a
combination of vintage bass sound and
the transparent ’EBS’ sound that let your
playing style and the character of your
instrument speak. Versatility is provided
by a carefully designed EQ with a wide
range of possible settings. By using the
built in auxiliary input in stereo, you can
use this combo for practicing at home
with headphones. These brief tutorials
will help you to become acquainted with
some of the features of the EBS
Session30 combo.
GETTING STARTED...
1. Carefully unpack the bass combo.
2. Check that the Volume and Gain controls
are set to zero, fully counter clockwise.
Set the two filter controls to mid position.
Now the EBS Session30s' settings are
"zeroed" and ready to be personalized.
3. Power up the combo and plug in your
bass.
4. While plucking the strings as hard as you
would during your hardest playing, adjust
the GAIN knob until the PEAK led starts
to flash only at highest peaks.
5. Move over to the VOLUME knob and
adjust for the desired output volume.
BUILDING THE SOUND...
Your EBS Session30 features a tone
shaping circuit that will enable you to
create a variety of bass sounds.
The filters are basically the boost/cut
6.
design. This means that the level controls
marked with + and - signs, either boost or
cuts the selected frequency band.
7. Gradually increase or decrease the level
and vary the frequency of the various
filter sections. Notice how the sound is
affected.
8. If you have an MP3 player or other sound
source, you may connect this to the Aux In
input. Note that the volume must be
controlled from the source here, since this
input has no associated level control.
This was a brief tutorial of EBS
Session30. As you go on further in this
manual, you will learn how to use and
utilize all of the useful features that the
EBS Session30 offers you.

BLOCK DIAGRAM PANEL CONTROLS AND FUNCTIONS
INPUT - A low noise, high impedance
instrument input for all types of
instruments, active and passive.
___________________________________
GAIN - Control to adjust the instruments'
signal strength to the right operating level in
the Session120.
For optimum basic signal level, turn up the
GAIN knob until the PEAK led starts
flashing from the strongest signal from the
instrument.
Note: A correctly set GAIN is vital for the
signal processing to work properly in the
Session30.
__________________________________
AUX IN - This input will accept a stereo or
mono 3.5mm plug and gives you the option
of mixing in an external source such as
MP3 player or similar to the Session30.
Since this input does not have any level
control, be sure to control the volume from
the source.
Both channels will be mixed in from this
input.
The signal at this input will not be present
at the balanced output.
VOLUME - The VOLUME knob controls
all volume in the unit, controlling the
poweramp/speaker and headphones
output. The balanced output (XLR) is not
effected by the setting of this knob.
__________________________________
HEADPHONES – Connect your favorite
headphones here. By connecting the headphones the speakers will automatically be
muted. This headphones output is a mono
output.
__________________________________
BALANCED OUTPUT - Is a high
quality balanced output that functio ns as a
line box for connecting to PA mixing
consoles or to studio or broadcast
recording units.
Lifting ground is a great aid in many
occasions. When required, set the Gnd Lift
switch to inner position to disconnect the
ground from the output.
The Aux In signal is not present at this
output.

FILTERS POWER AMP • CABINET
FILTERS - The filter section
contains two versatile filters:
BASS is a 'shelving' type bass
filter with a wide gain range.
TREBLE is a 'shelving' type
filter controlling the higher
mids and treble registers,
giving presence and ambiance
to the sound.
POWERAMP - The internal poweramp is
of highly integrated design giving natural
sound reproduction and output with exceptional clarity.
The incorporated soft clip system provides tube-alike distortion characteristics,
protects the power amp from saturation
and increases its output performance and
sound quality.
__________________________________
CABINET - The cabinet is formed by
one specially designed fullrange 8"
speaker. In addition, the cabinet is
carefully tuned for best bass response.
