PA Speaker System
These operating instructions are intended for
users with basic knowledge in audio tech-
nology. Please read the instructions carefully
prior to operation and keep them for later
reference.
1 Applications
These speaker systems of the MEGA series have
been designed as 2-way systems for PA applica-
tions of highest requirements. They have a robust
cabinet of high-quality birch plywood. The cab-
inet shape and a great number of fixing points
integrated into the cabinet offer many setup and
mounting options. The tweeter and the bass
speaker of a speaker system can be controlled
together via the internal crossover network or
directly.

2 Important Notes

The speaker system corresponds to all relevant
directives of the EU and is therefore marked
with .
•
The speaker system is suitable for indoor use
only. Protect it against dripping water and
splash water, high air humidity and heat (ad-
missible ambient temperature range 0 – 40 °C).
•
For cleaning only use a dry, soft cloth, never use
chemicals or water.
•
No guarantee claims for the speaker system and
no liability for any resulting personal damage or
material damage will be accepted if the speaker
system is used for other purposes than originally
intended, if it is not correctly connected, over-
loaded, not safely mounted, or not repaired in
an expert way.
If the speaker system 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 Setting up or Mounting
Place the speaker system on a solid ground e. g.
on the stage and direct it towards the audience.
With its bevelled cabinet shape, the system can
also be used as a stage monitor radiating diago-
nally upwards.
Alternatively, the speaker system can be
placed onto a standard speaker stand with 35 mm
tube diameter (e. g. from the PAST series) via the
stand sleeve in the lower side.
For additional mounting possibilities, e. g.
suspension, numerous M8 threaded jacks are in-
tegrated into the cabinet. To use them, remove
the corresponding cover screws (hexagon socket
screws).
3.1 Turning the tweeter
For operating the speaker system mainly in a
horizontal position (e. g. as a floor monitor), the
tweeter may be turned by 90° for a wider radi-
ation of the high frequencies. For this purpose,
remove the metal front (lateral screws), remove
the four screws of the tweeter, turn the tweeter
counter-clockwise by 90° and then retighten it.
4 Selecting the Operating Mode
Select the desired operating mode with the MODE
SWITCH on the rear side of the system.
IMPORTANT: To prevent switching noise and
damage to speaker or amplifier, do not actuate
this switch during operation!

The bass speaker is directly controlled via the
contacts 1+ / 1− and the tweeter via the contacts
2+ / 2− of the Speakon jacks. For this operating
®
mode, the frequency splitting of the signal must
already take place ahead of or in the amplifier (e. g.
by means of a DSM-240 or DSM-260LAN; presets
for these speakers under: www.monacor.com).
An unfiltered signal must never reach the
tweeter; this signal may overload the tweeter (for
recommended crossover frequency see table).
5 Connection
Only make the connection or change the existing
connection with the amplifier switched off.
1) Connect the amplifier output to one of the two
Speakon jacks on the rear side of the speaker
system. After inserting the speaker plug into
the jack, turn the plug clockwise until it locks.
To remove the plug, withdraw the latch lock at
the plug and turn the plug counter-clockwise.
2) Another speaker system may be connected to
the other jack. All contacts of both jacks are
connected in parallel with each other. Make
sure that the amplifier will not be overloaded
by the parallel connection of several speakers.
Subject to technical modifications.
