Using the Klark Teknik DN9650 Digital Audio Network Bridge is easy. First, connect the included power supply to the bridge and plug it into a power outlet. Keep in mind that this unit doesn't have a Network Module, so you'll need to provide your own if required. When using, place it in a well - ventilated area to prevent overheating. For maintenance, regularly check the power supply for any signs of damage. Wipe the unit with a dry, soft cloth to keep it clean. Avoid using harsh chemicals on it as this could damage the surface.
