About the EBS Magni 500 Bass Combo!

The name ’Magni’ stems from a character in
Norse mythology – Magni, son of Thor (the
God of Thunder). The word Magni translates
to ‘Strong’ and is indeed significant for these
thunderous Magni 500 bass combos!

The Magni 500 combo is based on the
Reidmar 470 amp design. It is available in
two configurations, sporting either 2x10” or
1x15” speakers, and a tweeter. The rig can
be extended with an 8 ohm passive speaker
cabinet.

The Magni 500 is designed and developed
in the heart of Sweden by EBS.

GETTING STARTED...

1. Carefully unpack the bass combo.

2. Check that all knobs are set fully counter
clockwise besides the EQ controls marked
BASS, MIDDLE and TREBLE which should be
set to mid position. Make also sure all push
switches are set to their outer positions. Now
the EBS Magni 500 settings are "zeroed" and
ready to be personalized.

BUILDING THE SOUND...

7. The first tonal shaping circuitry is the
Character Filter next to the GAIN control.
This filters provides a preshape EQ prior of
further fine tuning of your sound.

8. Enable the filters by pressing the Filter
Active pushbutton and explore the filter
section. Play your bass. Note that there
isn't any difference in sound yet.

9. The filters are basically of the boost/cut
design. This means that the level controls
marked with + and -signs, either boost or
cuts the selected frequency band. Further,
the MIDDLE section has got a frequency
control for precise adjustment of the midrange.

10. Gradually increase or decrease the level
and vary the frequency of the middle filter
when operating the middle filter. Notice how
the sound is effected. An A/B comparison can
be made by toggling the filter active switch.

11. Proceed to the COMP/LIMIT knob. This
control adjusts the compression and is useful
when playing very dynamic or loud.

3. If you add another cabinet, make sure
the impedance of that cabinet is not below
8 ohms.

4. Turn on the POWER switch.

5. Plug in your bass. While plucking the
strings as hard as you would during your
hardest playing, gradually increase the
GAIN knob unit the peak LED starts to flash
at peaks.

6. Move over to the VOLUME knob and
adjust for the desired output volume.

12. Turn up the COMP/LIMIT knob to mid
and max position. Notice how the peaks in
volume will straighten out as you play harder
and harder.

13. Now, go on to the BRIGHT and turn it
half way up. Play your bass. The BRIGHT
filter is a high pass filter which works on
the highest fre quencies of the bass to give
enhanced ambiance and presence.

This was a brief introduction and as you go
on further in this manual, you will learn how
to use and utilize all of the useful features
that the EBS Magni 500 offers you.

1. INPUT

-A low noise, high impedance
instrument input that will inter face with
passive and active instruments perfectly.

2. CHARACTER FILTER -The EBS Magni 500

provides a preshape filter, Character, which
operate independently from the other
preamp functions. This gives the user the
opportunity to preshape the sound before
the final processing with the other features
of the preamp. When on, boost is achieved
in bass and treble ranges respectively, while
the midrange has a slight drop in gain.

3. GAIN -Control to adjust the instruments’

signal strength to the right operating level
in the EBS Magni 500. 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 EBS Magni 500.

4. COMP/LIMIT -A low noise compressor

limiter that works fast and effectively,
tightening up the sound and preventing
the bass head from saturating at peaks
when approaching the headroom limit. A
string may be plucked very hard and fast,
without any greater difference in level or
side effects. The COMP/LIMIT knob sets the
compression ratio, i.e. The signal strength
relation between the input and output; the
higher ratio the more compression. The LED
intensity dynamically indicates the amount
of compression during play.

5. FILTER ACTIVE – This switch actives the filter

section described under point 6.

6. FILTERS

enhanced performance filters:

BASS is a ’shelving’ type 12dB/oct slope
phase compensated bass filter with a wide
gain range.

MIDDLE has an extended frequency range
of 100-6000 Hz. This filter facilitates
total control over the mids, with a wide
bandwidth giving a natural and non­peaking result using frequency dependent
gain. In addition, at minimum setting this
filter facilitates a notch function, suitable for
cutting an exact frequency or eliminating
acoustic coupling.

TREBLE is a shelving type filter controlling
the higher mids and treble registers, giving
presence and ambience to the sound.

BRIGHT is an advanced high pass filter
capable of producing bright high treble
timbre, without adding practically any noise.

-The filter section contains four

7. VOLUME -The VOLUME knob controls

all volume in the unit, controlling the
poweramp and LINE output. The balanced
output (XLR) is not affected by the setting of
this knob.

8. PILOT LAMP -Indicates power on condition.

1. BALANCED OUTPUT

functions as a high quality line box for
connecting to PA mixing consoles or to
studio or broadcast recording units, with
high noise immunity. The volume level does
not effect this output.

-A balanced output

2. GND LIFT SWITCH -Lifting ground is a great

aid in many occasions eliminating ground
noise and hum. When required, set this
switch to Lift position to disconnect the
ground from the balanced output.

3. PRE/POST EQ SWITCH -The switch selects the

signal source. In the inner position this
switch selects the overall sound included
settings on the EQ, otherwise, in the lower
position an uncolored sound is taken
immediately after the amplifiers input.

4. EFFECTS LOOP – This is a serial effects loop

for the use of external units such as box or
rack effects. Nominal level is set for use
with standard stomp boxes.
The loop puts the external effects after the
filter, compressor and drive sections.

5. LINE OUT -This is a fullrange output that will

drive multiple poweramps, extending the
power of the system. The signal present at
this output is taken after the volume control.

6. PHONES - 1/4” stereo contact to connect

a pair of standard headphones.

7. SPEAKER OUTPUT – Option to connect an

extra speaker here. The impedance must
not be lower than 8 ohms.

Warning: Lower impedance than 8 ohms may cause
permanent damage to the amp.

8. MAINS SELECTOR SWITCH -Selects the

operating mains voltage. Unplug the amp
before selecting the mains voltage!

9. MAINS – Connect only to the indicated

mains AC voltage and replace fuse if
needed only with same type and value.

10. POWER -Switches the amp on or off.
