2 Safety Notes

This unit corresponds to all relevant directives of
the EU and is therefore marked with
WARNING The unit uses dangerous mains
voltage (230 V~). Leave servicing
to skilled personnel only and do
not insert anything into the air
vents! Inexpert handling of the unit
may result in electric shock.
Please observe the following items in any case:
G
The unit is suitable for indoor use only. Protect
it against dripping water and splash water,
high air humidity and heat (admissible ambi-
ent temperature range: 0 – 40 °C).
G
Do not place any vessel filled with liquid on the
unit, e. g. a drinking glass.
G
The heat generated inside the unit must be
dissipated by air circulation; never cover the
air vents of the housing and the cooling fins
(14). Never position the rear side of the
speaker system directly against a wall; always
make sure the distance is sufficient.
G
Do not operate the unit and immediately dis-
connect the mains plug from the socket
1. if the unit or the mains cable is visibly dam-
aged,
2. if a defect might have occurred after the unit
was dropped or suffered a similar accident,
3. if malfunctions occur.
In any case the unit must be repaired by
skilled personnel.
G
Never pull the mains cable to disconnect the
mains plug from the socket; always seize the
plug.
G
For cleaning only use a dry, soft cloth; never
use water or chemicals.
G
No guarantee claims for the unit and no liabil-
ity for any resulting personal damage or mate-
rial damage will be accepted if the unit is used
for other purposes than originally intended, if it
is not correctly connected or operated, or if it
is not repaired in an expert way.
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harmful
to the environment.

3 Applications

The speaker systems of the MEGA DSP series
are high-performance active speaker systems in
rugged wooden housings. They are suitable for
a wide range of applications, e. g. for dances, for
smaller stages or as monitor speakers for bands.
The speakers are designed as 2-way systems.
Each of them is provided with a separate ampli-
fier for the bass speaker and tweeter ranges.
The amplifiers are equipped with protective cir-
cuits against overload and overheating.
The speaker systems include two balanced
signal inputs; one of them can be switched to
microphone sensitivity. For the other input,
unbalanced connections are available. Addi-
tional signal outputs allow, for example, for the
.
connection of further active speaker systems.
The digital signal processor (DSP) is the
core component of the MEGA-DSP series, offer-
ing numerous options for changing the sound,
readjusting the delay time and limiting the
dynamic range. The DSP can be remotely con-
trolled via a computer network. Various configu-
rations may be saved as presets in the speaker
system and can thus be made available for
standalone operations.

4 Setup and Connection

Place the speaker system on a firm ground, e. g.
on the stage or on a table and align it to the ears
of the listeners. Due to its bevelled housing, the
speaker system can be used as a stage monitor,
radiating diagonally upwards. If a microphone is
to be used, do not direct the speaker towards the
microphone and make sure that the distance
between the speaker system and the micro-
phone is sufficient; otherwise, an acoustic feed-
back (loud howling) may occur.
Alternatively, use the stand sleeve located
on the lower side of the speaker system to place
the speaker onto a standard speaker stand with
a tube diameter of 35 mm (e. g. from the PAST
series of the "img Stage Line" product range).
To support additional mounting options, the
housing is provided with numerous M8 threaded
jacks where, for example, mounting brackets
(MHB-.../ MVB-...) or the ring bolt delivered with
the speaker system can be fastened. To use the
M8 threaded jacks, remove the corresponding
cover screws (hexagon socket screws).
When positioning the speaker system,
always make sure that air is able to flow freely
through the cooling fins (14) on the rear side of
the system to provide sufficient cooling.
WARNING Installations which are not made in
an expert way are a hazard, espe-
cially if systems are suspended
(flown) above persons. Therefore,
the installation must only be made
by expert personnel familiar with
the valid standards and safety reg-
ulations.
The installation, especially the stability of the
mounting connections, must be checked at reg-
ular intervals.

4.1 Turning the tweeter

If the speaker system is to be mainly operated in
a horizontal position (e. g. as a floor monitor), the
tweeter may be turned by 90° for a wider radia-
tion of the high frequencies. For this purpose,
remove the metal front (lateral screws), remove
the four screws of the tweeter and retighten the
tweeter in a position turned counterclockwise
by 90°.
