•

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. 

•

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. 

•

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”) 

•

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. 

•

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. 

•

Repairs, servicing and electric connection must be carried out by a qualified technician. 

•

For replacement use fuses of same type and rating only. 

•

WARRANTY: Till one year after date of purchase.
