INTRODUCTION

REAR PANEL DESCRIPTION

Welcome to the EBS Reidmar BassHead!

The EBS Reidmar 250 provides a full bodied, warm
and transparent tone throughout the entirerange.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 Reidmar does not compromiseonthetone,
it uses and benefits from all the 250 Watts, without
getting muddy or clipping, giving a powerful and
highly portable amp with an impressive tone that will
handle any stageor studio session 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.

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. AnA/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.

connecting speakers so that the minium total
impedance is not lower than 4 ohms.

Note: Lower impedance than 4 ohms may cause
permanent damage to the amp.
