PSS-110 MKIII
Ordercode: D2611
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.
●
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.
● Never leave any cables lying around.
● Do not connect this system to a dimmer pack.
● Do not open the device and do not modify the device.
● Only use device indoors, avoid contact with water or other liquids.
● 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!
● 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.
● 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 sure that the power switch is in the OFF
position.
● Before switching on or off make sure 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 (parallel or series) an amplifier output with any other amplifier output.
● Do not drive the inputs with a signal level higher than required to drive the equipment to full output.
● Do not run the output of any amplifier channel, back into another channel’s input.
● 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.
● 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.
● If your DAP Audio device fails to work properly, discontinue use immediately. Pack the unit securely
(preferably in the original packing material), and return it to your DAP Audio dealer for service.
● In system setup, the amplifier's output power must be set 50%-100% higher than the loaded
loudspeakers’ rated power.
● 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 do not 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
● 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 PSS have sufficient power rating.
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.
