Danger to hearing!

Extended listening at high volumes may lead to 

hearing loss.

high volumes.

volume and the unit is activated, very high noise pressure 

may suddenly be produced. This may have psychological 

consequences and also cause physical injury. Children 

and pets are particularly at risk. Set your signal source
