Do not connect (parallel or series) an amplifier output with any other amplifier output.
Only use system indoor, avoid contact with water or other liquids.
Avoid flames and do not put close to flammable liquids or gases.
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.
Make sure you don’t use the wrong kind of cables or defective cables.
Make sure that the signals into the mixer are balanced, otherwise hum could be created.
Make sure you use DI boxes to balance unbalanced signals; All incoming signals should be clear
Make sure that there is sufficient room on all sides of the system for air circulation.
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 system and the power-
cord from time to time.
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).
Avoid installing your equipment very near radio or TV sets, mobile phones, etc., as these can
cause RF (radio frequency) interference.
When connecting the other parts of your sound system, watch out for the so-called “ground
loops”.
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.
Before changing your grounds around, always turn your amplifiers down.
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.
Always operate the unit with the AC ground wire connected to the electrical system ground.
Do not drive the inputs with a signal level bigger, than required to drive the equipment to full
output.
In system setup, the amplifier's output power must be 50%-100% more than the loaded
loudspeakers rated power.
Please turn off the power switch, when changing the power cord or signal cable, or select the
input mode switch.
Sometimes, when you want to send one signal to more than one amplifier, you should use a signal
distributor.
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.
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”)
For replacement use fuses of same type and rating only.
Prevent distortion! Make sure that all components connected to the Soundmate have sufficient
power ratings. Otherwise distortion will be generated because the components are operated at
their limits.
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!
If system 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.
Repairs, servicing and electric connection must be carried out by a qualified technician.
WARRANTY: Till one year after date of purchase.
