Make sure that the amplifier is turned down, before turning the power on or off. So you can avoid
supersonic frequencies, which could damage your speakers.
Don't put your equipment next to TV, radio, etc., because of interference or distortion.
If you connect other parts of the system, be careful of ground loops.
The best way to avoid ground loops is connecting the electrical system ground to one central
point ("star" system). In this case the mixer can act as a central point.
Before changing the ground, always turn off your amplifier.
Please read this manual carefully and keep it for future reference. Remember that the amplifier
has a better value on the market, if you save the carton and all packing materials.
Always operate the unit with the AC ground wire connected to the electrical system ground.
Connecting amplifier outputs to oscilloscopes or other test equipment, while the amplifier is in
bridged mode, may damage both the amplifier and test equipment.
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.
In typical use, please set the volume at 0dB position.
Sometimes, when you want to send one signal to more than one amplifier, you should use a signal
distributor.
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.
Allow time to cool down, before cleaning or servicing.
For replacement use fuses of same type and rating only.
Prevent distortion! Make sure that all components connected to the DSA 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.
This device falls under protection class I. Therefore it is essential to connect the yellow/green
conductor to earth.
Repairs, servicing and electric connection must be carried out by a qualified technician.
WARRANTY: Till one year after date of purchase.
