FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY
CAUTION! Be careful with your operations.
a dangerous electric shock when touching the wires!
Warning
BEFORE YOUR INITIAL START-UP!
Unpacking Instructions
Immediately upon receiving this product, carefully unpack the carton and check the contents to ensure
that all parts are present and have been received in good condition. Notify the dealer immediately and
retain packing material for inspection if any parts appear damaged from shipping or the carton itself
shows signs of mishandling. Save the carton and all packing materials. In the event that a fixture must be
returned to the factory, it is important that the fixture be returned in the original factory box and packing.
Safety Instructions
Every person involved with the installation, operation and maintenance of this device have to:
- be qualified
- follow the instructions of this manual
Before your initial start-up, please make sure that there is no damage caused by transportation. Should
there be any, consult your dealer and do not use the device.
To maintain perfect condition and to ensure a safe operation, it is absolutely necessary for the user to
follow the safety instructions and warning notes written in this manual.
Please consider that damages caused by manual modifications to the device are not subject to
warranty. This device contains no user-serviceable parts. Refer servicing to qualified technicians only.
IMPORTANT!
The manufacturer will not accept liability for any resulting damages caused by the nonobservance of this manual or any unauthorized modification to the system.
Always disconnect power from the mains, when system is not used. Only handle the power-cord by
the plug. Never pull out the plug by tugging the power-cord.
Always operate the unit with the AC ground wire connected to the electrical system ground.
Avoid flames and do not put close to flammable liquids or gases.
Avoid ground loops! Always be sure to connect the power amps and the mixing console to the
same electrical circuit to ensure the same phase!
Avoid installing your equipment very near radio or TV sets, mobile phones, etc., as these can cause
RF (radio frequency) interference.
Before changing your grounds around, always turn your amplifiers down.
Before connecting or disconnecting the power cord, make certain the ON / OFF switch is in the OFF
position.
Before switching on or off make certain the sound system’s amplifiers are off or turned down: this will
avoid signal peaks, which are annoying and sometimes dangerous (particularly for speaker
enclosures).
Do not connect this device to a dimmer pack.
With a dangerous voltage you can suffer

Disposing of this product should not be placed in municipal waste and should be
separate collection.
Do not drive the inputs with a signal level bigger, than required to drive the equipment to full output.
Do not open this device. Risk: hazardous radiation exposure.
Do not switch the system on and off in short intervals, as this would reduce the system’s life.
Extreme frequency boosts in connection with a high input signal level may lead to overdriving your
equipment. Should this occur, it is necessary to reduce the input signal level by using the INPUT
control.
For replacement use fuses of same type and rating only.
If device is dropped or struck, disconnect mains power supply immediately. Have a qualified
engineer inspect for safety before operating.
If the system has been exposed to drastic temperature fluctuation (e.g. after transportation), do not
switch it on immediately. The arising condensation water might damage your system. Leave the
system switched off until it has reached room temperature.
Keep this user’s manual for future consultation. Also remember that the crossover will get a better
price on the secondhand market if (as well as being in good condition) it has its original
documentation and packaging.
Make sure that the available voltage is not higher than stated on the rear panel.
Make sure that the power-cord is never crimped or damaged. Check the device and the power-
cord from time to time.
Make sure that the signals into the mixer are balanced, otherwise hum could be created.
Make sure that there is sufficient room on all sides of the system for air circulation.
Make sure you don’t use the wrong kind of cables or defective cables.
Make sure you use DI boxes to balance unbalanced signals; All incoming signals should be clear
Never let the power-cord come into contact with other cables! Handle the power-cord and all
connections with the mains with particular caution!
Never remove warning or informative labels from the unit.
Never use anything to cover the ground contact.
Only use device indoor, avoid contact with water or other liquids.
Please turn off the power switch, when changing the power cord or signal cable, or select the input
mode switch.
Prevent distortion! Make sure that all components connected to the M10/M12/M15 active monitor
have sufficient power ratings. Otherwise distortion will be generated because the components are
operated at their limits.
Repairs, servicing and electric connection must be carried out by a qualified technician.
Sometimes, when you want to send one signal to more than one amplifier, you should use a signal
distributor.
The best way (even if not always feasible) to avoid ground loops is to connect the electric ground of
all the equipment to a single central point (“star” system). In this case, the central point can be the
mixer.
To avoid or solve hum and buzzing troubles, try different combinations of lifting grounds on units that
are supplied with ground lift switches or make sure all chassis are connected to earth ground, either
through the A.C. power cord ground or by the front panel rack mount screws.
To emphasize a frequency range, you don’t necessarily have to move its respective sliding control
upward; try lowering surrounding frequency ranges instead. This way, you avoid causing the next
piece of equipment in your sound path to overdrive. You also preserve valuable dynamic reserve
(“headroom”)
WARRANTY: Till one year after date of purchase.
When connecting the other parts of your sound system, watch out for the so-called “ground loops”.
