Warning
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 non-
observance of this manual or any unauthorized modification to the system.
Avoid flames and do not put close to flammable liquids or gases.
Before changing your grounds around, always turn your amplifiers down.
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 drive the inputs with a signal level bigger, than required to drive the equipment to full output.
Do not open this device.
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.
If device is dropped or struck, disconnect mains power supply immediately. Have a qualified
engineer inspect for safety before operating.
In system setup, the amplifier's output power must be 50%-100% more than the loaded loudspeakers
rated power.
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 there is sufficient room on all sides of the system for air circulation.
FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY
BEFORE YOUR INITIAL START-UP!
CAUTION! Be careful with your operations.
With a dangerous voltage you can suffer
a dangerous electric shock when touching the wires!

Make sure you don’t use the wrong kind of cables or defective cables.
Never remove warning or informative labels from the unit.
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 DRX-series 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.
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.
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”.

Connection Cables
Take care of your cables, always holding them by the connectors and avoiding knots and twists when
coiling them: This gives the advantage of increasing their life and reliability.
Periodically check your cables. A great number of problems (faulty contacts, ground hum, discharges,
etc.) are caused entirely by using unsuitable or faulty cables.
