Cooling fan
The DD 820 M's intelligent micro-processor controlled
cooling fan continuously monitors all the operating
parameters of the output stages and the mains power
supply unit.
Temperature data is measured at several points, and the
machine uses this information together with load and
output level data to calculate a requirement profile for
cooling fan power, and the output of the fan is set to one
of three stages accordingly.
This method of regulation enables the DD 820 M to
deliver high output levels for several hours continuously
without problem and without overheating.
At the other extreme fan power is reduced in quiet music
passages, keeping the output stages at the optimum
operating temperature for sound quality. Fan noise is
minimised at this setting.
The fan must never be blocked by cables

etc. Ensure that the fan blades are free to
rotate, and cannot be obstructed.
