TIPS
Burn in/ Warm up
Your audio components need a certain time period until they reach maximum performance. The duration of this "warm up" time is very diffe- rent for the various elements of your audio system. Higher and homogeneous sound quality is achie- ved while keeping the device switched on.

Net frequency noise
Some audio source devices may in combination with the amplifier cause a humming noise at power line frequency audible from your speakers. Usually, its volume varies with the volume setting of the amplifier. This is no sign of a defect or fault of your audio products but has to be eliminated. Generally, every
Experience shows that this problem is mainly cau- sed by
speakers, subwoofers, record players or headpho- ne amplifiers that are connected to the audio inputs of the amplifier. Another possible reason for humming noise is electromagnetic interference of other components’ power supplies with
In most electric devices the ground potentials of all signals are connected to each other at one central point, where they have one common connection. If the device uses the protective conductor of the wall outlet, the corresponding wire of the line cord is connected intractably to the metal housing of the device. This is the mostly the point where the central grounding point is attached to. By doing this the housing is able to shield all signals from external radiated noise. Some main amplifiers are equipped with a "Ground
If the problem occurs and cannot be solved by yourself your audio specialist dealer will help you.
