DAPAudio K-115, Product Manual

3 

Do not connect this device to a dimmerpack. 

Do not open the device and do not modify the device. 

Do not switch the device on and off in short intervals, as this would reduce the system’s life. 

Do not shake the device. Avoid brute force when installing or operating the device. 

Do not run the output of any amplifier channel, back into another channel’s input. 

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 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. 

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 to 0dB position. 

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 K-115 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. 

The user is responsible for correct positioning and operating of this device. The manufacturer will 
not accept liability for damages caused by the misuse or incorrect installation of this device. 

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

WARRANTY: Till one year after date of purchase. 

OPERATING DETERMINATIONS 

If this system is operated in any other way, than the one described in this manual, the product may suffer 
damages and the

warranty becomes void.  

Any other operation may lead to dangers like short-circuit, burns, electric shock, etc. 
 
You endanger your own safety and the safety of others! 
 

Improper installation can cause serious damage to people and property !
