INTRODUCTION
REAR PANEL DESCRIPTION
Welcome to the EBS Reidmar Bass Head!
The EBS Reidmar provides a full bodied, warm and
transparent tone throughout the entire range. It is
equipped with EBS renowned built in compressor,
professional balanced XLR-output, Character filter
and an efficient 4-Band EQ that lets you master the
sound. The Reidmardoes not compromiseon the tone,
it uses and benefits from all the 250 Watts RMS,
without getting muddy or clipping, giving a powerful
and highly portable amp with an impressive tone that
will handle anystage or studiosession gig.
The EBS Reidmar handles a 4 Ohm load and is the
perfect companion to a stack of Mini size ClassicLine
or NeoLine cabinets, or used with a single full size
EBS cabinet.
The Reidmar amp is designed and developed in the
heart of Swedenby EBS.
GETTING STARTED...
1. Carefully unpack the bass head.
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 Reidmars settings
are "zeroed" and ready to be personalized.
3. Connect one or more speaker cabinets to the
speaker output. Make sure the total
impedance is not below 4 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.
BUILDING THE SOUND...
7. The first tonal shaping circuitry is the
Character Filter
This filters provides a preshape EQ
prior of further fine tuning of your sound.
8. Enable the filters by pressing the
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.
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 frequencies of the bass to give enhanced ambiance
and presence.

limiterthat works fast andeffectively,tightening
up the sound and preventing the bass head from

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.
